Strange issue, but on one device Android no longer lets the app create a directory (or any directories). This seems to have happened since I moved to SDK 27 (I brought in a 3rd party library that requires the upgrade). Even stranger, it works on other devices. The device that does not work is a Samsung Galaxy Tab S3, running Android 8 (sdk 26).
Here is the code that fails:
public static String mediaStorageDirectory() {
return Environment.getExternalStorageDirectory().toString() + File.separator + "myapp";
}
private DatabaseHelper(Context context) {
super(context, DB_NAME, null, 1);
File dbPath = new File(Utilities.mediaStorageDirectory() + "/databases/");
if (!dbPath.exists()) {
if (dbPath.mkdirs()) {
this.mContext = context;
createDataBase();
}
}
}
The code creates a directory, then copies the app DB in into that directory. This code has been working since the dawn of time...has Android changed some security requirements for file creation?
If you are wondering, I have set privileges as follows:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
And the user is prompted for those privileges successfully before the creation of the directory structure.
So the problem seems to be related to SDK 27. Seems they are now requiring (enforcing?) that the permissions for WRITE be granted. Previously only READ was required. I would assume that this was related to security upgrades, but I could not find any documentation on this change. Perhaps everyone else just did the inclusion previously. For those wanting to see code that does the permissions handling, I pulled the following code from another Stack Overflow a while back. I merely added the WRITE_EXTERNAL_STORAGE part that was previously missing:
final private int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 124;
public void checkPermissions() {
List<String> permissionsNeeded = new ArrayList<String>();
final List<String> permissionsList = new ArrayList<String>();
if (!addPermission(permissionsList, Manifest.permission.CAMERA))
permissionsNeeded.add("Camera");
if (!addPermission(permissionsList, Manifest.permission.READ_EXTERNAL_STORAGE))
permissionsNeeded.add("Read External Storage");
if (!addPermission(permissionsList, Manifest.permission.WRITE_EXTERNAL_STORAGE))
permissionsNeeded.add("Write External Storage");
if (!addPermission(permissionsList, Manifest.permission.ACCESS_FINE_LOCATION))
permissionsNeeded.add("GPS");
if (!addPermission(permissionsList, Manifest.permission.RECORD_AUDIO))
permissionsNeeded.add("Record Audio");
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);
}
message = message + "." + " If you do not the application may not function correctly.";

The call is SDK specific, added to the OnCreate() of your main activity:
// Check permissions for Android 6.0 devices
if (Build.VERSION.SDK_INT >= 23) {
// Marshmallow+
checkPermissions();
}
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.

The following methodology is about
asking permissions dynamically ;
showing a AlertDialog if the user denies any permission
looping until the user accepts permission(s)
Create a "static" class for permissions methods
public class PermissionsUtil {
public static final int PERMISSION_ALL = 1;
public static boolean doesAppNeedPermissions(){

🔥 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 static final int MULTIPLE_PERMISSIONS = 1;
public static final int CAMERA_PERMISSION_REQUEST_CODE = 2;
public static final int STORAGE_PERMISSION_REQUEST_CODE = 3;
private void askPermissions() {
int permissionCheckStorage = ContextCompat.checkSelfPermission(this,
Manifest.permission.WRITE_EXTERNAL_STORAGE);
int permissionCheckCamera = ContextCompat.checkSelfPermission(this,
Manifest.permission.CAMERA);
// we already asked for permisson & Permission granted, call camera intent
if (permissionCheckStorage == PackageManager.PERMISSION_GRANTED && permissionCheckCamera == PackageManager.PERMISSION_GRANTED) {
launchCamera();
} //asking permission for the first time
else if (permissionCheckStorage != PackageManager.PERMISSION_GRANTED && permissionCheckCamera != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE},
MULTIPLE_PERMISSIONS);
} else {
// Permission denied, so request permission
// if camera request is denied
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.CAMERA)) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("You need to give permission to take pictures in order to work this feature.");
builder.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
});
builder.setPositiveButton("GIVE PERMISSION", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
// Show permission request popup
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.CAMERA},

}
});
builder.show();
} // if storage request is denied
else if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.WRITE_EXTERNAL_STORAGE)) {

}
});
builder.show();
}
}
}
Checking Permission Results
#Override
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:

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.

.....
// 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
I am properly allowing and denying permission and app is running properly first time but when all permission is granted and next time when user launches the app, it shows only splash screen and become stable and do not move to next activity , and it also not give any error , what i am trying is below.

perms.put(android.Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
perms.put(android.Manifest.permission.READ_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.READ_SMS,PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.READ_CONTACTS,PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.READ_CALL_LOG,PackageManager.PERMISSION_GRANTED);
// Fill with results
for (int i = 0; i < permissions.length; i++)
perms.put(permissions[i], grantResults[i]);
if (perms.get(android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
&& perms.get(android.Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED

finish();
}
}
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
because if all permissions are granted then this will be false and there is no else case to do anything
if (permissionsList.size() > 0)
{
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
}
so it should be like this
if (permissionsList.size() > 0)
{
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
}
else{
startActivity(new Intent(Splash.this,UserGuideActivity.class));
finish();
}
Improvements : you can eliminate creating map and loop by making reuse of checkMultiplePermissions function but modification will be required at other places accordingly
Check this condition :
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
{
checkMultiplePermissions();
}else{
startActivity(new Intent(Splash.this,UserGuideActivity.class));
finish();
}
Nothing will happen after checkMultiplePermissions() is run, so you need to add startActivity there only when permissions are granted.
Hope this helps !
As you described in your question that it is working first time and you are giving all permissions. So according to your code if all permissions are granted it will not go to onRequestPermissionsResult. And you have written your Intent part in that method so it will stick to same screen.
Add else statement as stated by Pavneet
Try to create method to check is all permission is granted or not if not granted then it will automatically ask each permission additional pass isAllPermissionRequired flag to use same method on onRequestPermissionsResult if you not required all permission move another screen

if (!listPermissionsNeeded.isEmpty()) {
if(isAllPermissionRequired) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
return false;
}else {
return true;
}
}
return true;
}
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
if (requestCode == REQUEST_ID_MULTIPLE_PERMISSIONS) {
if (checkAndRequestPermissions(false)) {
startActivity(new Intent(Splash.this,UserGuideActivity.class));
finish();
}
}
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(checkAndRequestPermissions(true)){
startActivity(new Intent(Splash.this,UserGuideActivity.class));
finish();
}
}
Note : Above sample i have pass isAllPermissionRequired = true from onCreate to ask for each permission and isAllPermissionRequired = false from onRequestPermissionsResult to not ask any permission even user not grant but you need to pass isAllPermissionRequired = true in onRequestPermissionsResult if required all permission mandatory.
I am trying to get all permission in a single dialog file and I followed the below link which provided me with an example
http://inthecheesefactory.com/blog/things-you-need-to-know-about-android-m-permission-developer-edition/en
This is my code
public class MActivity extends AppCompatActivity {
final private int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 124;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_m);
insertDummyContactWrapper();
}
#TargetApi(Build.VERSION_CODES.M)
private void insertDummyContactWrapper() {
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();
}
#TargetApi(Build.VERSION_CODES.M)
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(MActivity.this)
.setMessage(message)
.setPositiveButton("OK", okListener)
.setNegativeButton("Cancel", null)
.create()
.show();
}
private static final String TAG = "Contacts";
private void insertDummyContact() {
// Two operations are needed to insert a new contact.
ArrayList<ContentProviderOperation> operations = new ArrayList<ContentProviderOperation>(2);
// First, set up a new raw contact.
ContentProviderOperation.Builder op =
ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI)
.withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, null)

operations.add(op.build());
// Next, set the name for the contact.
op = ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)

"__DUMMY CONTACT from runtime permissions sample");
operations.add(op.build());
// Apply the operations.
ContentResolver resolver = getContentResolver();
try {
resolver.applyBatch(ContactsContract.AUTHORITY, operations);
} catch (RemoteException e) {
Log.d(TAG, "Could not add a new contact: " + e.getMessage());
} catch (OperationApplicationException e) {
Log.d(TAG, "Could not add a new contact: " + e.getMessage());
}
}
#Override

I got the dialog box which asked for the permission and after given ok I checked the setting-->apps-->myappname-->permission, but permission was not set ?
Can some one please help me in this matter.
When I added permission in my mainfest file it worked perfectly.
Note : But I did anotherway
public class RecursionActivity extends AppCompatActivity {
Context context;
private static final int PERMISSION_REQUEST_CODE = 1;
String p1 = android.Manifest.permission.READ_CONTACTS, p2 = android.Manifest.permission.ACCESS_FINE_LOCATION,
p3 = android.Manifest.permission.WRITE_CONTACTS, p4 = Manifest.permission.CAMERA;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context = this;
setContentView(R.layout.activity_recursion);
permissionAccess();
}
private void permissionAccess() {
if (!checkPermission(p1)) {
Log.e("TAG",p1);
requestPermission(p1);
} else if (!checkPermission(p2)) {
Log.e("TAG",p2);
requestPermission(p2);
} else if (!checkPermission(p3)) {
Log.e("TAG",p3);
requestPermission(p3);
} else if (!checkPermission(p4)) {
Log.e("TAG",p4);
requestPermission(p4);
} else {
Toast.makeText(context, "All permission granted", Toast.LENGTH_LONG).show();
}
}
private boolean checkPermission(String permission) {
int result = ContextCompat.checkSelfPermission(context, permission);
if (result == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
return false;
}
}
private void requestPermission(String permission) {
if (ContextCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(RecursionActivity.this, new String[]{permission}, PERMISSION_REQUEST_CODE);
} else {
//Do the stuff that requires permission...
Log.e("TAG","Not say request");
}
}
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
Log.e("TAG", "val " + grantResults[0]);
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
permissionAccess();
} else {
Toast.makeText(context, "Bye bye", Toast.LENGTH_LONG).show();
}
break;
}
}
}
I don't know whether this is an optimized solution or not but I hope it will be helpful for someone.
In your addPermission method add required permissions as follows:
ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.READ_PHONE_STATE,android.Manifest.permission.ACCESS_FINE_LOCATION,android.Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
