I know that Android 6.0 has new permissions and I know I can call them with something like this
if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) !=
PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[] {
Manifest.permission.WRITE_EXTERNAL_STORAGE
}, PERMISSION_WRITE_STORAGE);
}
Today I saw a Google app which needs 3 permissions: contacts, sms and camera. It's making a page 1-3 and calls them all together at the same time to activate.
Can anybody tell me how I can call 4 permissions to activate at the same time like sms, camera, contacts and storage?
Example (forgot the name of the google app :( )
The app needs sms,contacts and camera
the app asked me (and made a dialog page1-3) activate sms, activate contacts and then camera.
So this google app was calling all 3 required permissions together and my question is how can i achive the same ?
Just include all 4 permissions in the ActivityCompat.requestPermissions(...) call and Android will automatically page them together like you mentioned.
I have a helper method to check multiple permissions and see if any of them are not granted.
public static boolean hasPermissions(Context context, String... permissions) {
if (context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
Or in Kotlin:
fun hasPermissions(context: Context, vararg permissions: String): Boolean = permissions.all {
ActivityCompat.checkSelfPermission(context, it) == PackageManager.PERMISSION_GRANTED
}
Then just send it all of the permissions. Android will ask only for the ones it needs.
// The request code used in ActivityCompat.requestPermissions()
// and returned in the Activity's onRequestPermissionsResult()
int PERMISSION_ALL = 1;
String[] PERMISSIONS = {
android.Manifest.permission.READ_CONTACTS,
android.Manifest.permission.WRITE_CONTACTS,
android.Manifest.permission.WRITE_EXTERNAL_STORAGE,
android.Manifest.permission.READ_SMS,
android.Manifest.permission.CAMERA
};
if (!hasPermissions(this, PERMISSIONS)) {
ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}
Here is detailed example with multiple permission requests:-
The app needs 2 permissions at startup . SEND_SMS and ACCESS_FINE_LOCATION (both are mentioned in manifest.xml).
I am using Support Library v4 which is prepared to handle Android pre-Marshmallow and so no need to check build versions.
As soon as the app starts up, it asks for multiple permissions together. If both permissions are granted the normal flow goes.
public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(checkAndRequestPermissions()) {
// carry on the normal flow, as the case of permissions granted.
}
}
private boolean checkAndRequestPermissions() {
int permissionSendMessage = ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS);
int locationPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
List<String> listPermissionsNeeded = new ArrayList<>();
if (locationPermission != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
}
if (permissionSendMessage != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.SEND_SMS);
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
return false;
}
return true;
}
ContextCompat.checkSelfPermission(), ActivityCompat.requestPermissions(), ActivityCompat.shouldShowRequestPermissionRationale() are part of support library.
In case one or more permissions are not granted, ActivityCompat.requestPermissions() will request permissions and the control goes to onRequestPermissionsResult() callback method.
You should check the value of shouldShowRequestPermissionRationale() flag in onRequestPermissionsResult() callback method.
There are only two cases:--
Case 1:-Any time user clicks Deny permissions (including the very first time), it will return true. So when the user denies, we can show more explanation and keep asking again
Case 2:-Only if user select “never asks again” it will return false. In this case, we can continue with limited functionality and guide user to activate the permissions from settings for more functionalities, or we can finish the setup, if the permissions are trivial for the app.
CASE -1
CASE-2

It's easy, do this way
private static final int REQUEST_READ_PHONE_STATE = 110 , REQUEST_ACCESS_FINE_LOCATION = 111, REQUEST_WRITE_STORAGE = 112;
In your onCreate
//request permission
boolean hasPermissionPhoneState = (ContextCompat.checkSelfPermission(getApplicationContext(),
Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED);
if (!hasPermissionPhoneState) {
ActivityCompat.requestPermissions(LoginActivity.this,
new String[]{Manifest.permission.READ_PHONE_STATE},
REQUEST_READ_PHONE_STATE);
}
boolean hasPermissionLocation = (ContextCompat.checkSelfPermission(getApplicationContext(),
Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
if (!hasPermissionLocation) {
ActivityCompat.requestPermissions(LoginActivity.this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
REQUEST_ACCESS_FINE_LOCATION);
}
boolean hasPermissionWrite = (ContextCompat.checkSelfPermission(getApplicationContext(),
Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED);
if (!hasPermissionWrite) {
ActivityCompat.requestPermissions(LoginActivity.this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
REQUEST_WRITE_STORAGE);
}
Then check result
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode)
{
case REQUEST_READ_PHONE_STATE: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
//reload my activity with permission granted or use the features what required the permission
finish();
startActivity(getIntent());
} else
{
Toast.makeText(LoginActivity.this, "The app was not allowed to get your phone state. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
}
}
case REQUEST_ACCESS_FINE_LOCATION: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
//reload my activity with permission granted or use the features what required the permission
finish();
startActivity(getIntent());
} else
{
Toast.makeText(LoginActivity.this, "The app was not allowed to get your location. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
}
}
case REQUEST_WRITE_STORAGE: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
//reload my activity with permission granted or use the features what required the permission
finish();
startActivity(getIntent());
} else
{
Toast.makeText(LoginActivity.this, "The app was not allowed to write to your storage. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
}
}
}
}
My approach is based on Nicks' answer and hopefully is a bit more usable for multiple (as many as needed, not only two) permissions.
It suggests adding single-responsibility PermissionsHelper class:
import android.app.Activity;
import android.app.AlertDialog;
import android.content.pm.PackageManager;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.util.Log;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class PermissionsHelper {
private static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 100; // any code you want.
public void checkAndRequestPermissions(Activity activity, String... permissions) {
List<String> listPermissionsNeeded = new ArrayList<>();
for (String permission : permissions) {
if (ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(permission);
}
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(activity, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
}
}
public void onRequestPermissionsResult(Activity activity, int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case REQUEST_ID_MULTIPLE_PERMISSIONS: {
Map<String, Integer> perms = new HashMap<>();
for (String permission : permissions) {
perms.put(permission, PackageManager.PERMISSION_GRANTED);
}
if (grantResults.length > 0) {
for (int i = 0; i < permissions.length; i++)
perms.put(permissions[i], grantResults[i]);
boolean allPermissionsGranted = true;
for (String permission1 : permissions) {
allPermissionsGranted = allPermissionsGranted && (perms.get(permission1) == PackageManager.PERMISSION_GRANTED);
}
if (allPermissionsGranted) {
Log.d(PermissionsHelper.class.getSimpleName(), "onRequestPermissionsResult: all permissions granted");
} else {
for (String permission2 : perms.keySet())
if (perms.get(permission2) == PackageManager.PERMISSION_GRANTED)
perms.remove(permission2);
StringBuilder message = new StringBuilder("The app has not been granted permissions:\n\n");
for (String permission : perms.keySet()) {
message.append(permission);
message.append("\n");
}
message.append("\nHence, it cannot function properly." +
"\nPlease consider granting it this permission in phone Settings.");
AlertDialog.Builder builder = new AlertDialog.Builder(activity);
builder.setTitle(R.string.permission_required)
.setMessage(message)
.setPositiveButton(android.R.string.ok, (dialog, id) -> dialog.cancel());
AlertDialog alert = builder.create();
alert.show();
}
}
}
}
}
}
If one or several required permissions have not been granted by user, the detailed AlertDialog message will be shown to him.
Example of usage in Activity:
private PermissionsHelper permissionsHelper;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
checkPermissions();
//any other code
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
permissionsHelper.onRequestPermissionsResult(this, requestCode, permissions, grantResults);
}
private void checkPermissions() {
permissionsHelper = new PermissionsHelper();
permissionsHelper.checkAndRequestPermissions(this,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION);
}
Hope that this will be useful for someone.

🔥 NEW EASY AND CLEAN WAY OF ASKING MULTIPLE PERMISSIONS IN 2022 🔥
At the top of your activity class, write
private val multiplePermissionContract = registerForActivityResult(ActivityResultContracts.RequestMultiplePermissions()) { permissionsStatusMap ->
// permissionStatusMap is of type <String, Boolean>
// if all permissions accepted
if (!permissionsStatusMap.containsValue(false)) {
// All persmissions are accepted, do here whatever you want
} else {
Toast.makeText(this, "all permissions not accepted", Toast.LENGTH_SHORT).show()
}
}
And, launch the permission asking dialogs whenever you want like below(for now, I am thinking that you need to ask the permissions when you click on xyzButton)
xyzButton.setOnClickListener {
multiplePermissionContract.launch(
arrayOf(
android.Manifest.permission.READ_CONTACTS,
android.Manifest.permission.WRITE_CONTACTS,
android.Manifest.permission.WRITE_EXTERNAL_STORAGE,
android.Manifest.permission.READ_SMS,
android.Manifest.permission.CAMERA
)
)
}
NOTE -
registerForActivityResult() method will always be called whenever we click on xyzButton. If all any of the all permissions is not accepted earlier, it will ask that particular permission again; else it will directly execute the if condition block.
There is nothing wrong with answers asking for multiple permissions but multiple permission result code is not implemented very elegantly and may cause checking wrong permission result.
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) is terrible logic for checking multiple permissions result, i don't know why Google implemented such a terrible code.
It's a mess especially when you check multiple permissions. Let say you ask for CAMERA, ACCESS_FINE_LOCATION and ACCESS_NETWORK_STATE.
You need to check for ACCESS_FINE_LOCATION but user only granted CAMERA at first run and you check for grantResults[1] but in second run ACCESS_FINE_LOCATION becomes the permission with index 0. I got so many problems with user not granting all permissions at once and have to write so pointless permission result logic.
You should either use
int size = permissions.length;
boolean locationPermissionGranted = false;
for (int i = 0; i < size; i++) {
if (permissions[i].equals(Manifest.permission.ACCESS_FINE_LOCATION)
&& grantResults[i] == PackageManager.PERMISSION_GRANTED) {
locationPermissionGranted = true;
}
}
Or simpler one
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
// Do something ...
}
in onPermissionRequestResult method.
Checking every situation
if denied - showing Alert dialog to user why we need permission

public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case CAMERA_PERMISSION_REQUEST_CODE:
if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.CAMERA)) {
// check whether camera permission granted or not.
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
launchCamera();
}
}
break;
case STORAGE_PERMISSION_REQUEST_CODE:
if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
// check whether storage permission granted or not.
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
launchCamera();
}
}
break;
case MULTIPLE_PERMISSIONS:
if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.CAMERA) && permissions[1].equals(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
// check whether All permission granted or not.
if (grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
launchCamera();
}
}
break;
default:
break;
}
}
you can just copy and paste this code, it works fine. change context(this) & permissions according to you.
Short and sweet :). what I believe in.
int PERMISSION_ALL = 1;
String[] PERMISSIONS = {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}; // List of permissions required
public void askPermission()
{
for (String permission : PERMISSIONS) {
if (ActivityCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(PERMISSIONS, PERMISSION_ALL);
return;
}
}
}
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
int[] grantResults) {
switch (requestCode) {
case 1:{
if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED){
//Do your work.
} else {
Toast.makeText(this, "Until you grant the permission, we cannot proceed further", Toast.LENGTH_SHORT).show();
}
return;
}
}
After seeing all the long and complex answers. I want post this answer.
RxPermission is widely used library now for asking permission in one line code.
RxPermissions rxPermissions = new RxPermissions(this);
rxPermissions
.request(Manifest.permission.CAMERA,
Manifest.permission.READ_PHONE_STATE)
.subscribe(granted -> {
if (granted) {
// All requested permissions are granted
} else {
// At least one permission is denied
}
});
add in your build.gradle
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
dependencies {
implementation 'com.github.tbruyelle:rxpermissions:0.10.1'
implementation 'com.jakewharton.rxbinding2:rxbinding:2.1.1'
}
Isn't this easy?
I have successfully implemented simple code for Multiple permission at Once.
Follow the below steps
1:Make Utility.java class like below
public class Utility {
public static final int MY_PERMISSIONS_REQUEST = 123;
#TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public static boolean checkPermissions(Context context, String... permissions) {
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, permission)) {
ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE,Manifest.permission.GET_ACCOUNTS}, MY_PERMISSIONS_REQUEST);
} else {
ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE,Manifest.permission.GET_ACCOUNTS}, MY_PERMISSIONS_REQUEST);
}
return false;
}
}
}
return true;
}
}
2: Now call
boolean permissionCheck = Utility.checkPermissions(this, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CALL_PHONE, Manifest.permission.GET_ACCOUNTS);
in your Activity onCreate() or according to your logic.
3:Now check permission before performing operation for particular task
if (permissionCheck) {
performTaskOperation();//this method what you need to perform
} else {
Toast.makeText(this, "Need permission ON.", Toast.LENGTH_SHORT).show();
}
4: Now implement onRequestPermissionsResult() method in your Activity as below
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case Utility.MY_PERMISSIONS_REQUEST:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if (userChoosenTask.equals("STORAGE"))
performTaskOperation();//this method what you need to perform
}
break;
}
}
I just use an array to achieved multiple requests, hope it helps someone. (Kotlin)
// got all permission
private fun requestPermission(){
var mIndex: Int = -1
var requestList: Array<String> = Array(10, { "" } )
// phone call Permission
if (ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
mIndex ++
requestList[mIndex] = Manifest.permission.CALL_PHONE
}
// SMS Permission
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
mIndex ++
requestList[mIndex] = Manifest.permission.SEND_SMS
}
// Access photos Permission
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
mIndex ++
requestList[mIndex] = Manifest.permission.READ_EXTERNAL_STORAGE
}
// Location Permission
if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
mIndex ++
requestList[mIndex] = Manifest.permission.ACCESS_FINE_LOCATION
}
if(mIndex != -1){
ActivityCompat.requestPermissions(this, requestList, PERMISSIONS_REQUEST_ALL)
}
}
// permission response
override fun onRequestPermissionsResult(requestCode: Int,
permissions: Array<String>, grantResults: IntArray) {
when (requestCode) {
PERMISSIONS_REQUEST_ALL -> {
// If request is cancelled, the result arrays are empty.
if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission accept location
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
Log.d(TAG, "Phone Call permission accept.")
}
// permission accept location
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS) == PackageManager.PERMISSION_GRANTED) {
Log.d(TAG, "SMS permission accept.")
}
// permission accept location
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
Log.d(TAG, "SMS permission accept.")
}
// permission accept location
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
Log.d(TAG, "Location permission accept.")
}
} else {
Toast.makeText(mContext, "Permission Failed!", Toast.LENGTH_LONG).show()
}
return
}
}
}
I found this is in the runtime permissions example from Google's github.
private static String[] PERMISSIONS_CONTACT = {Manifest.permission.READ_CONTACTS,
Manifest.permission.WRITE_CONTACTS};
private static final int REQUEST_CONTACTS = 1;
ActivityCompat.requestPermissions(this, PERMISSIONS_CONTACT, REQUEST_CONTACTS);
Check the "Asking for multiple permissions at a time" section in this article:
Things you need to know about Android M permissions
It's very well explained, and may also touch other related topics you haven't think about.
Use helper like this (permissions names do not matter).
public class MyPermission {
private static final int PERMISSION_REQUEST_ALL = 127;
private MainActivity mMainActivity;
MyPermission(MainActivity mainActivity) {
mMainActivity = mainActivity;
}
public static boolean hasPermission(String permission, Context context) {
if (isNewPermissionModel()) {
return (ActivityCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED);
}
return true;
}
private static boolean hasPermissions(Context context, String... permissions) {
if (isNewPermissionModel() && context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
private static boolean shouldShowRationale(Activity activity, String permission) {
return isNewPermissionModel() && ActivityCompat.shouldShowRequestPermissionRationale(activity, permission);
}
private static boolean isNewPermissionModel() {
return VERSION.SDK_INT > VERSION_CODES.LOLLIPOP_MR1;
}
/**
* check all permissions
*/
void checkAll() {
//check dangerous permissions, make request if need (Android will ask only for the ones it needs)
String[] PERMISSIONS = {
permission.READ_CALENDAR,
permission.ACCESS_COARSE_LOCATION
};
if (!hasPermissions(mMainActivity, PERMISSIONS)) {
ActivityCompat.requestPermissions(mMainActivity, PERMISSIONS, PERMISSION_REQUEST_ALL);
}
}
void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if (requestCode == PERMISSION_REQUEST_ALL) {
if (grantResults.length > 0) {
//for not granted
for (int i = 0; i < permissions.length; i++) {
if (permissions[i].equals(permission.READ_CALENDAR)) {
if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {
smartRequestPermissions(permission.READ_CALENDAR, R.string.permission_required_dialog_read_calendar);
}
} else if (permissions[i].equals(permission.ACCESS_COARSE_LOCATION)) {
if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {
smartRequestPermissions(permission.ACCESS_COARSE_LOCATION, R.string.permission_required_dialog_access_coarse_location);
}
}
}
}
}
}
private void smartRequestPermissions(final String permissionName, int permissionRequiredDialog) {
if (shouldShowRationale(mMainActivity, permissionName)) {// If the user turned down the permission request in the past and chose the Don't ask again option in the permission request system dialog, this method returns false.
//Show an explanation to the user with action
mMainActivity.mSnackProgressBarManager.show(

)
.setAction("OK", new OnActionClickListener() {

})
.setSwipeToDismiss(true).setAllowUserInput(true)

Simple way to ask multiple permission,
https://github.com/sachinvarma/EasyPermission
How to add :
repositories {
maven { url "https://jitpack.io" }
}
implementation 'com.github.sachinvarma:EasyPermission:1.0.1'
How to ask permission:
List<String> permission = new ArrayList<>();
permission.add(EasyPermissionList.READ_EXTERNAL_STORAGE);
permission.add(EasyPermissionList.ACCESS_FINE_LOCATION);
new EasyPermissionInit(MainActivity.this, permission);
For more Details - >
https://github.com/sachinvarma/EasyPermission/blob/master/app/src/main/java/com/sachinvarma/easypermissionsample/MainActivity.java
It may help someone in future.
In Kotlin:
private val id = 1
private val permissions = arrayOf(Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.ACCESS_FINE_LOCATION)
fun hasPermissions(): Boolean {
for (perm in permissions) {
if (ActivityCompat.checkSelfPermission(this, perm) != PackageManager.PERMISSION_GRANTED) {
return false
}
}
return true
}
if(! hasPermissions()){
requestPermissions(this, permissions, id)
}
This is what I have done in my activity. Hoping will be helpful. I am asking for camera and microphone permissions.
public class ActiveCallActivity extends AppCompatActivity {
.....
private static final String cameraPermissionKey = "cameraPermission";
private static final String microphonePermissionkey = "microphonePermission";
private static ArrayList<String> permissionsQueue = new ArrayList<String>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
.....
// in ValidationCheckersAndValidators simply checking if have permission or not.
if(ValidationCheckersAndValidators.haveCameraPermission(this)) performHaveCameraPermissionLayout(); else performHaveNoCameraPermissionLayout();
if(ValidationCheckersAndValidators.haveMicrophonePermission(this)) performHaveMicrophonePermissionLayout(); else performHaveNoMicrophonePermissionLayout();
}
private void performHaveNoCameraPermissionLayout() {
.....
permissionsQueue.add(cameraPermissionKey);
}
private void performHaveNoMicrophonePermissionLayout() {
.....
permissionsQueue.add(microphonePermissionkey);
}
#Override
protected void onResume() {
super.onResume();
.....
passThroughPermissionsQueue();
}
private void passThroughPermissionsQueue() {
if(!permissionsQueue.isEmpty()) {
String permissionKey = permissionsQueue.remove(0);
switch (permissionKey) {
case cameraPermissionKey: {
ValidationCheckersAndValidators.requestForCameraPermission(this);
return;
}
case microphonePermissionkey: {
ValidationCheckersAndValidators.requestForMicrophonePermission(this);
return;
}
}
}
}
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch(requestCode) {
case cameraPermissionRequestCode: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
performHaveCameraPermissionLayout();
}
break;
}
case microphonePermissionRequestCode: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
performHaveMicrophonePermissionLayout();
}
break;
}
}
passThroughPermissionsQueue();
}
}
You can use Dexter
In build.gradle add:
implementation 'com.karumi:dexter:5.0.0'
And use it in your activity as:
val requiredPermissions = when {
Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q -> listOf(Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.ACCESS_BACKGROUND_LOCATION)
else -> listOf(Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION)
}
Dexter.withActivity(this)
.withPermissions(
requiredPermissions
)
.withListener(object : MultiplePermissionsListener {
override fun onPermissionRationaleShouldBeShown(
permissions: MutableList<PermissionRequest>?,
token: PermissionToken?
) {
/* ... */
}
override fun onPermissionsChecked(report: MultiplePermissionsReport) =
if (report.isAnyPermissionPermanentlyDenied) {
toast("You should grant all permissions")
} else {
toast("All permissions granted")
// continue here if permission is a must
}).check()
// continue here if permission is not a must

So here My problem is that Its Asking two Permission at a time...
If I try to grant them its moving to another Activity... So I have Given Similar 3 activities with 2 Permission on Each..
But Due to Handler its Opening new activities..
Then I removed Delay Handler... Now It opening Last activity... Directly...
Can Any one Suggest Me How to Start The Main Activity after All Permissions only...
Without permission It should Exit app... Please Help me on this
Update
Insted of Multiple permissions I have Splited the 3 activities with two permission each... But here It should Go to next activity after permission But its Going to last activity every time first two activity permission are missing
So I need to exit app and give them...
All I need is that without permission don't move to next screen
Can any one suggest me after permission only move to next activity....

You have to make method for check permission for each
for ex. this is for READ CONTACT, same way add all other
private boolean checkReadContactPermission() {
int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.READ_CONTACTS);
if (result == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
return false;
}
}
Method for request permissions
private void requestPermission() {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_CONTACTS,
Manifest.permission.WRITE_CONTACTS,
Manifest.permission.READ_PHONE_STATE,
/* Manifest.permission.CAMERA,*/
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_EXTERNAL_STORAGE},
PERMISSION_REQUEST_CODE);
}
finally RequestPermissionResult
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
// if granted then 0 else -1
// i have 5 permisson to check so 0,1,2,3,4..
if (grantResults[0] == PackageManager.PERMISSION_GRANTED &&
grantResults[1] == PackageManager.PERMISSION_GRANTED &&
grantResults[2] == PackageManager.PERMISSION_GRANTED &&
grantResults[3] == PackageManager.PERMISSION_GRANTED &&
grantResults[4] == PackageManager.PERMISSION_GRANTED) {
// means all permission are granted..move to Main activity
} else {
// show alert
}
break;
}
}
When you request for permission(s) you'll receive results in onRequestPermissionsResult handle results from inside as google docs says here
Updated
The permissions you mentioned are grouped ones example
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE
it will ask only one permission for that and one will be for calls(Reading phone state) and you don't need to ask for permission for accessing network state and internet
I am working on an app in which I want to ask multiple permission at run time.
My code is worked fine for one Permission. However when I want to ask for multiple permission my code does nothing .
Can anyone tell me what wrong with my code?

Any kind of help is appreciate by me thanks.
First check permission is already granted or not.
Here you can check more then one permissions.
if (checkForPermission(getActivity(), CAMERA_PERMISSION) && checkForPermission(getActivity(), GALLERY_PERMISSION)) {
//Permission granted here
//TODO
} else {
requestPermissions(new String[]{CAMERA_PERMISSION, GALLERY_PERMISSION}, 1);
}
checkForPermission method.
/***
* Method is checking permission for Marshmallow
*
* #param context
* #param permission
* #return
*/
private static boolean checkForPermission(final Context context, String permission) {
int result = ContextCompat.checkSelfPermission(context, permission);
//If permission is granted then it returns 0 as result
if (result == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
return false;
}
}
onRequestPermissionsResult method its like onActivityResult.
/***
* This is call when user allow or deny permissions in the Marshmallow
*
* #param requestCode
* #param permissions
* #param grantResults
*/
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case 1:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
//Permission granted here
//TODO
}
break;
}
}
In your activity:
private static final int MY_PERMISSIONS = 111;
in onCreate method:
String[] mPermissionToRequest = new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.CAMERA,Manifest.permission.CALL_PHONE};
ActivityCompat.requestPermissions(this, mPermissionsToRequest, MY_PERMISSIONS);
#Override
public void onRequestPermissionsResult( int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
}
Check for your AndroidManifest.xml file:
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
For Multiple Permisions:
public abstract class AbsRuntimePermission extends Activity {
private SparseIntArray mErrorString;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mErrorString = new SparseIntArray();
}
public abstract void onPermissionsGranted(int requestCode);
public void requestAppPermissions(final String[]requestedPermissions, final int stringId, final int requestCode) {
mErrorString.put(requestCode, stringId);
int permissionCheck = PackageManager.PERMISSION_GRANTED;
boolean showRequestPermissions = false;
for(String permission: requestedPermissions) {
permissionCheck = permissionCheck + ContextCompat.checkSelfPermission(this, permission);
showRequestPermissions = showRequestPermissions || ActivityCompat.shouldShowRequestPermissionRationale(this, permission);
}
if (permissionCheck!=PackageManager.PERMISSION_GRANTED) {
if(showRequestPermissions) {
Snackbar.make(findViewById(android.R.id.content), stringId, Snackbar.LENGTH_INDEFINITE).setAction("GRANT", new View.OnClickListener() {
#Override
public void onClick(View v) {
ActivityCompat.requestPermissions(AbsRuntimePermission.this, requestedPermissions, requestCode);
}
}).show();
} else {
ActivityCompat.requestPermissions(this, requestedPermissions, requestCode);
}
} else {
onPermissionsGranted(requestCode);
}
}
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
int permissionCheck = PackageManager.PERMISSION_GRANTED;
for(int permisson : grantResults) {
permissionCheck = permissionCheck + permisson;
}
if( (grantResults.length > 0) && PackageManager.PERMISSION_GRANTED == permissionCheck) {
onPermissionsGranted(requestCode);
} else {
//Display message when contain some Dangerous permisson not accept
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(new ContextThemeWrapper(this, android.R.style.Theme_Holo_Light_Dialog));
alertDialogBuilder
.setMessage("Please enble permisions")
.setTitle("Please enble permisions")
.setCancelable(false)
.setPositiveButton(" Enable",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Intent i = new Intent();
i.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
i.setData(Uri.parse("package:" + getPackageName()));
i.addCategory(Intent.CATEGORY_DEFAULT);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
i.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
startActivity(i);
}
});
alertDialogBuilder.setNegativeButton(" Cancel ", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.show();
}
}
}
And In Your Main Activity:
public class MainActivity extends AbsRuntimePermission {
private static final int REQUEST_PERMISSION = 10;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
requestAppPermissions(new String[]{
Manifest.permission.READ_CONTACTS,
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.WRITE_CONTACTS},
R.string.msg,REQUEST_PERMISSION);
}
#Override
public void onPermissionsGranted(int requestCode) {
//Do anything when permisson granted
Toast.makeText(getApplicationContext(), "Permission granted", Toast.LENGTH_LONG).show();
}
}
try this:
final private int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 124;
public boolean checkMultiplePermission() {
List<String> permissionsNeeded = new ArrayList<String>();
final List<String> permissionsList = new ArrayList<String>();
if (!addPermission(permissionsList, Manifest.permission.ACCESS_FINE_LOCATION))
permissionsNeeded.add("GPS");
if (!addPermission(permissionsList, Manifest.permission.READ_CONTACTS))
permissionsNeeded.add("Read Contacts");
if (!addPermission(permissionsList, Manifest.permission.WRITE_CONTACTS))
permissionsNeeded.add("Write Contacts");
if (permissionsList.size() > 0) {
if (permissionsNeeded.size() > 0) {
// Need Rationale
String message = "You need to grant access to " + permissionsNeeded.get(0);
for (int i = 1; i < permissionsNeeded.size(); i++)
message = message + ", " + permissionsNeeded.get(i);
showMessageOKCancel(message,
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
}
});
return;
}
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
return;
}
insertDummyContact();
}
private boolean addPermission(List<String> permissionsList, String permission) {
if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
permissionsList.add(permission);
// Check for Rationale Option
if (!shouldShowRequestPermissionRationale(permission))
return false;
}
return true;
}
private void showMessageOKCancel(String message, DialogInterface.OnClickListener okListener) {
new AlertDialog.Builder(MainActivity.this)
.setMessage(message)
.setPositiveButton("OK", okListener)
.setNegativeButton("Cancel", null)
.create()
.show();
}
When every single permission got its grant result, the result will be sent to the same callback method, onRequestPermissionsResult()
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS:
{
Map<String, Integer> perms = new HashMap<String, Integer>();
// Initial
perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.READ_CONTACTS, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.WRITE_CONTACTS, PackageManager.PERMISSION_GRANTED);
// Fill with results
for (int i = 0; i < permissions.length; i++)
perms.put(permissions[i], grantResults[i]);
// Check for ACCESS_FINE_LOCATION
if (perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
&& perms.get(Manifest.permission.READ_CONTACTS) == PackageManager.PERMISSION_GRANTED
&& perms.get(Manifest.permission.WRITE_CONTACTS) == PackageManager.PERMISSION_GRANTED) {
// All Permissions Granted
//do your task..
} else {
// Permission Denied
Toast.makeText(MainActivity.this, "Some Permission is Denied", Toast.LENGTH_SHORT)
.show();
}
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
Hope this helps u..
do this...
on on create
int PERMISSION_ALL = 1;
String[] PERMISSIONS = {Manifest.permission.CAMERA,Manifest.permission.WRITE_EXTERNAL_STORAGE};
if(!hasPermissions(this, PERMISSIONS)){
//ask user for granting permissions on api22+
ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}
Checking if already permission...
public static boolean hasPermissions(Context context, String... permissions) {
//checaking if the application has permission
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
This is for camera and read storage, you can add whatever you want...
you can achieve this by this way
private static final int MY_PERMISSIONS_REQUEST_CALL = 7;
private static String[] PERMISSIONS = {
Manifest.permission.CALL_PHONE, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE};
now create a method
public void checkSmsPermission() {
try {
if (Build.VERSION.SDK_INT >= 23) {
if (ActivityCompat.checkSelfPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED
|| ActivityCompat.checkSelfPermission(context, Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED ||
ActivityCompat.checkSelfPermission(context, Manifest.permission.CALL_PHONE)
!= PackageManager.PERMISSION_GRANTED
) {
requestPermission();
} else
checkLogin();
} else {
checkLogin();
}
} catch (Exception e) {
e.printStackTrace();
}
}
you can check grants result array for checking which permission is granted
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
try {
boolean flagDenied = false;
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_CALL:
if (grantResults.length > 0
) {
for (int i : grantResults)
if (i == -1) {
flagDenied = true;
break;
}
if (!flagDenied)
doJob();
else showPermissionDialog();
}
break;
}
} catch (Exception e) {
e.printStackTrace();
}
}
My code is worked fine for one Permission. However when I want to ask
for multiple permission my code does nothing.
Leaving aside that your code is too verbose and makes it harder to read, the checkMultiplePermission() method works fine. I have copied it into a test project and when I started the app I was asked for the 5 permissions.
(5 because WRITE_EXTERNAL_STORAGE/READ_EXTERNAL_STORAGE and ACCESS_FINE_LOCATION/ACCESS_COARSE_LOCATION are merged each into a single permission request)
Please double check that you updated your AndroidManifest.xml file with the new permissions.
It can be that previously when you were testing your code with only one permission, you accepted it, then more permissions were added to the request logic but forgotten to be listed in the AndroidManifest.xml. In this case Android will ignore your request, nor will throw it an exception, it will simply do nothing.
I am trying to take an image from Gallery and set it to an imageview but in Android 6 there are some permission problems. Below is the method to ask for the permission. Should I ask for read external storage or write external storage?
Here is what I have done so far:
private static final int READ_CONTACTS_PERMISSIONS_REQUEST = 1;
public void getPermissionToReadExternalStorage() {
if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
if (shouldShowRequestPermissionRationale(
Manifest.permission.READ_EXTERNAL_STORAGE)) {
requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
READ_CONTACTS_PERMISSIONS_REQUEST);
}}}
#Override
public void onRequestPermissionsResult(int requestCode,
#NonNull String permissions[],
#NonNull int[] grantResults){
// Make sure it's our original READ_CONTACTS request
if (requestCode == READ_CONTACTS_PERMISSIONS_REQUEST) {
if (grantResults.length == 1 &&
grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(getActivity(), "Read Contacts permission granted", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getActivity(), "Read Contacts permission denied", Toast.LENGTH_SHORT).show();
}
} else {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
Now my on click listener to pick data from the Gallery:
pro.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
if (android.os.Build.VERSION.SDK_INT >= 23) {
getPermissionToReadExternalStorage();
if (getPermissionToReadExternalStorage () this???? <==)
startActivityForResult(Intent.createChooser(intent, "Select Picture"), 0);
} else {
startActivityForResult(Intent.createChooser(intent, "Select Picture"), 0);
}}
});
return v;
}
Now I want to get result of the method getPermissionToReadExternalStorage() so I can start the Activity for picking gallery for Android 6. How can I get the result of the void class?
And another thing is do I have to write method for every permission my app asks for?
So I have completely rewritten the code to request permissions.
Now it supports requesting for multiple permissions and running code with proper result.
Also it works with preMarshmallow devices, so you don't have to check and copy the code in that case.
First, create an Activity class with this code (You can extend any king of activity you need, e.g. AppCompatActivity):
public abstract class PermissionActivity extends AppCompatActivity {
private final ArrayList<PermissionListener> permissionListeners = new ArrayList<>();
#SuppressWarnings("unused")
public void requestPermissions(int requestCode, String[] requestPermissions, PermissionListener permissionListener) {
requestPermissions(requestCode, requestPermissions, null, permissionListener);
}
#SuppressWarnings("unused")
public void requestPermissions(final int requestCode, String[] requestPermissions, String message, final PermissionListener permissionListener) {
final int[] grantResults = new int[requestPermissions.length];
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
ArrayList<String> list_notGranted = new ArrayList<>();
for (String requestPermission : requestPermissions)
if (ContextCompat.checkSelfPermission(this, requestPermission) != PackageManager.PERMISSION_GRANTED)
list_notGranted.add(requestPermission);
if (list_notGranted.size() > 0) {
permissionListeners.add(permissionListener);
requestPermissions = list_notGranted.toArray(new String[list_notGranted.size()]);
if (message != null) {
boolean shouldShowRequestPermissionRationale = false;
for (String permission : requestPermissions)
if (ActivityCompat.shouldShowRequestPermissionRationale(this, permission)) {
shouldShowRequestPermissionRationale = true;
break;
}
if (shouldShowRequestPermissionRationale) {
final String[] f_requestPermissions = requestPermissions;
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(message);
DialogInterface.OnClickListener onClickListener = new DialogInterface.OnClickListener() {
#TargetApi(Build.VERSION_CODES.M)
#Override
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case DialogInterface.BUTTON_POSITIVE:
PermissionActivity.super.requestPermissions(f_requestPermissions, requestCode);
break;
default:
for (int i = 0; i < grantResults.length; i++)
grantResults[i] = PackageManager.PERMISSION_DENIED;
if (permissionListener != null)
permissionListener.onResult(requestCode, f_requestPermissions, grantResults);
break;
}
}
};
builder.setPositiveButton("OK", onClickListener);
builder.setNegativeButton("Cancel", onClickListener);
builder.show();
} else {
super.requestPermissions(requestPermissions, requestCode);
}
} else {
super.requestPermissions(requestPermissions, requestCode);
}
} else {
for (int i = 0; i < grantResults.length; i++)
grantResults[i] = PackageManager.PERMISSION_GRANTED;
if (permissionListener != null)
permissionListener.onResult(requestCode, requestPermissions, grantResults);
}
} else {
if (permissionListener != null) {
for (int i = 0; i < grantResults.length; i++)
grantResults[i] = PackageManager.PERMISSION_GRANTED;
permissionListener.onResult(requestCode, requestPermissions, grantResults);
}
}
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String permissions[], #NonNull int[] grantResults) {
for (Iterator<PermissionListener> it = permissionListeners.iterator(); it.hasNext(); ) {
PermissionListener permissionListener = it.next();
if (permissionListener.onResult(requestCode, permissions, grantResults)) {
it.remove();
}
}
}
public interface PermissionListener {
boolean onResult(int requestCode, String[] requestPermissions, int[] grantResults);
}
}
If you want to request permissions from Fragments, add this class:
public class PermissionFragment extends Fragment {
#SuppressWarnings("unused")
public void requestPermissions(int requestCode, String[] requestPermissions, PermissionActivity.PermissionListener permissionListener) {
requestPermissions(requestCode, requestPermissions, null, permissionListener);
}
#SuppressWarnings("unused")
public void requestPermissions(final int requestCode, String[] requestPermissions, String message, PermissionActivity.PermissionListener permissionListener) {
((PermissionActivity) getActivity()).requestPermissions(requestCode, requestPermissions, message, permissionListener);
}
}
Your Activities and Fragments should extend these classes instead of the standart ones.
Now you are ready to request the permissions by calling a method:
requestPermissions(int requestCode, String[] requestPermissions, PermissionListener permissionListener)
If the permission is required for the app to work, you should call this method and specify the message saying why the permission is required.
requestPermissions(int requestCode, String[] requestPermissions, String message, PermissionListener permissionListener)
DONT MISSCALL THE DEFAULT METHOD, WHICH IS
// DON'T USE THIS ONE!
requestPermissions(String[] requestPermissions, int requestCode)
// DON'T USE THIS ONE!
Here is the example of requesting contacts:
private void requestAndLoadContacts() {
String[] permissions = new String[]{Manifest.permission.READ_CONTACTS};
requestPermissions(REQUEST_PERMISSIONS_CONTACTS, permissions, "Read contacts permission is required for the app to work!", new PermissionListener() {
#Override
public boolean onResult(int requestCode, String[] requestPermissions, int[] grantResults) {
// Check if the requestCode is ours
if (requestCode == REQUEST_PERMISSIONS_CONTACTS) {
// Check if the permission is correct and is granted
if (requestPermissions[0].equals(Manifest.permission.READ_CONTACTS) && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Permission granted
// Calling a method to actually load the contacts
loadContacts();
} else {
// Permission not granted
Toast.makeText(MainActivity.this, "Access denied!", Toast.LENGTH_SHORT).show();
}
return true;
}
return false;
}
});
}
NOTE:
When you implement the PermissionListener, don't forget to return true when the requestCode is the correct one, otherwise the PermissionListener won't be removed from the ArrayList and you'll most likely get a small memory leak.
EDIT
I have rewritted the code and posted in another answer.
Old answer:
Yes, you have to check and ask for permission every time.
Usually I write the code like this:
private int requestPermissionCode;
private Runnable requestPermissionRunnable;
private void runPermissionCode(String requestPermission, int requestCode, Runnable codeToRun) {
if (android.os.Build.VERSION.SDK_INT >= 23) {
if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
requestPermissionCode = requestCode;
requestPermissionRunnable = codeToRun;
requestPermissions(new String[]{requestPermission},
requestCode);
}
} else {
codeToRun.run();
}
}
#Override
public void onRequestPermissionsResult(int requestCode,
#NonNull String permissions[],
#NonNull int[] grantResults) {
if (requestCode == requestPermissionCode) {
if (grantResults.length == 1 &&
grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if (requestPermissionRunnable != null)
requestPermissionRunnable.run();
} else {
Toast.makeText(getActivity(), "Permission denied", Toast.LENGTH_SHORT).show();
}
} else {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
and run it like this:
runPermissionCode(Manifest.permission.READ_EXTERNAL_STORAGE, READ_CONTACTS_PERMISSIONS_REQUEST, new Runnable() {
#Override
public void run() {
// your code here
}
});
I am sure it is not a best way, but at least it gives a possibility to request permission and make actions easier.
Initialize Your Permission
private static final int INITIAL_REQUEST = 1337;
private static final int GET_ACCOUNTS = INITIAL_REQUEST+2;
private static final int LOCATION_REQUEST =INITIAL_REQUEST+3;
private static final String[] INITIAL_PERMS = {
Manifest.permission.GET_ACCOUNTS,
Manifest.permission.INTERNET,
Manifest.permission.ACCESS_FINE_LOCATION
};
Check for device and Request for permissions
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!canAccessAccounts()|| !canAccessLocation() ||!canAccessInternet()) {
requestPermissions(INITIAL_PERMS, INITIAL_REQUEST);
}
}
Check Permission is granted Or not
private boolean canAccessAccounts() {
return (hasPermission(Manifest.permission.GET_ACCOUNTS));
}
private boolean canAccessLocation() {
return (hasPermission(Manifest.permission.ACCESS_FINE_LOCATION));
}
private boolean canAccessInternet() {
return (hasPermission(Manifest.permission.INTERNET));
}
private boolean hasPermission(String perm) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
return (PackageManager.PERMISSION_GRANTED == checkSelfPermission(perm));
}
return (true);
}
Update Permissions and Check method for permissions onRequestPermissionsResult
void UpdatePermissions(){
canAccessInternet();
canAccessLocation();
canAccessInternet();
}
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
UpdatePermissions();
switch(requestCode) {
case GET_ACCOUNTS:
if (canAccessAccounts()) {
}
else {
}
break;
case LOCATION_REQUEST:
if (canAccessLocation()) {
}
else {
}
break;
case INITIAL_REQUEST:
if(canAccessInternet()){
}else {
}
break;
}
}
