SMS does not send in Marshmallow

SMS does not send in Marshmallow - android

I am trying to open System default Messaging activity when clicking on a button. Here is my code:
smsUri = Uri.parse("tel:" + teacherPhone2);
Intent intent = new Intent(Intent.ACTION_VIEW, smsUri);
intent.putExtra("address", teacherPhone);
intent.setType("vnd.android-dir/mms-sms");
startActivity(intent);
It works fine below MarshMallow. But in MarshMallow the app crashes when clicking that button. I have set the user-permission and also requested send sms permission.
Can anyone tell me why this happens?

Check runtime permission before sending sms:
if (Build.VERSION.SDK_INT >= 23) {
int checkCallPhonePermission = ContextCompat.checkSelfPermission(RegistrationActivity.this,Manifest.permission.SEND_SMS);
if(checkCallPhonePermission != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(RegistrationActivity.this,new String[]{Manifest.permission.SEND_SMS},SEND_SMS);
return;
}else{
sendSms(mobile);
}
} else {
sendSms(mobile);
}

1. Add SEND_SMS permission in manifest
<uses-permission android:name="android.permission.SEND_SMS"/>
2. Request permission if not granted, send sms otherwise
if (Build.VERSION.SDK_INT >= 23) {
int checkCallPhonePermission = ContextCompat.checkSelfPermission(RegistrationActivity.this,Manifest.permission.SEND_SMS);
if(checkCallPhonePermission != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(RegistrationActivity.this,new String[]{Manifest.permission.SEND_SMS},SEND_SMS);
return;
} else{
sendSms(mobile);
}
} else {
sendSms(mobile);
}
3. Override onActivityResult in order to send sms after permission is granted
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
int checkCallPhonePermission = ContextCompat.checkSelfPermission(RegistrationActivity.this,Manifest.permission.SEND_SMS);
if(checkCallPhonePermission == PackageManager.PERMISSION_GRANTED){
sendSms(mobile);
}
}

The reason may be in MarshMallow we can turn off and on permissions for particular app. So check for permissions turned on or off before sending SMS.

String[] PERMISSIONS = {Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_SMS, Manifest.permission.CAMERA};
if(!hasPermissions(this, PERMISSIONS)){
ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}
public static boolean hasPermissions(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) {
return false;
}
}
}
return true;
}
try this code

Android check camera permission in target sdk 22 or lower

I have my code like this to check camera permission.
if (Build.VERSION.SDK_INT >= 23) {
Log.e("Permission State",ContextCompat.checkSelfPermission(activity, Manifest.permission.CAMERA)+"");
// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(activity, Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED){
showCameraActivityForResult(activity);
}else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.CAMERA}, Constant.MY_PERMISSIONS_REQUEST_CAMERA);
}
}else{
showCameraActivityForResult(activity);
}
Problem is that I always have permission granted in 5.1 or lower. Other user also said here.
How can I know if my app's camera permission is granted?
In some device like samsung, user can disable camera permission from device setting and as a result, when user open my app and tap on camera, it always show blank. How can I detect whether user can use camera? (it need to be different from my code since it is not working.)

If you use AppCompatActivity, you can use checkSelfPermission to check if permission have been granted.
if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, Manifest.permission.CAMERA)) {
//Show permission dialog
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions((Activity)context, new String[]{Manifest.permission.CAMERA}, code);
}
}

On API 22 and below permissions are granted if specified in the manifest.
For API 23+ ContextCompat#checkSelfPermission could be of use. It "degrades" gracefully on earlier APIs and will tell you the permission is granted if it appears in the manifest. On API 23 and above it will actually check if it's granted.
It returns PackageManager.PERMISSION_GRANTED if the permission is granted.
call it in an Activity with Manifest.permission.CAMERA to avoid typos.
ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA));

Try this,
private Context mContext=YourActivity.this;
private static final int REQUEST = 112;
if (Build.VERSION.SDK_INT >= 23) {
String[] PERMISSIONS = {android.Manifest.permission.CAMERA};
if (!hasPermissions(mContext, PERMISSIONS)) {
ActivityCompat.requestPermissions((Activity) mContext, PERMISSIONS, REQUEST );
} else {
showCameraActivityForResult(activity);
}
} else {
showCameraActivityForResult(activity);
}
get Permissions Result
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case REQUEST: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
showCameraActivityForResult(activity);
} else {
Toast.makeText(mContext, "The app was not allowed to write in your storage", Toast.LENGTH_LONG).show();
}
}
}
}
check permissions for marshmallow
private static boolean hasPermissions(Context context, String... permissions) {
if (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;
}
Manifest
<uses-permission android:name="android.permission.CAMERA" />
OR :
if (Build.VERSION.SDK_INT >= 23)
{
Log.e("Permission State",ContextCompat.checkSelfPermission(activity, Manifest.permission.CAMERA)+"");
// Here, thisActivity is the current activity
if (ActivityCompat.checkSelfPermission(activity, android.Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED)
{
showCameraActivityForResult(activity);
}
else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(activity, new String[]{android.Manifest.permission.CAMERA}, Constant.MY_PERMISSIONS_REQUEST_CAMERA);
}
}else{
showCameraActivityForResult(activity);
}

checkSelfPermission is available above sdk 23.
we can check the permission is available or not using package manager
public static Boolean checkpermissions(Activity activity) {
PackageManager mPackageManager = activity.getPackageManager();
int hasPermStorage = mPackageManager.checkPermission(android.Manifest.permission.CAMERA, activity.getPackageName());
if (hasPermStorage != PackageManager.PERMISSION_GRANTED) {
// do stuff
// Toast.makeText(getApplicationContext(), "No permission", Toast.LENGTH_LONG).show();
return false;
} else if (hasPermStorage == PackageManager.PERMISSION_GRANTED) {
// do stuff
// Toast.makeText(getApplicationContext(), "Has permission", Toast.LENGTH_LONG).show();
return true;
} else {
return false;
}

Not able to get Android run time permission result

I want to check SMS reading permission is Granted or not in API 23+. So I implemented its as follows;
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS) != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, PERMISSIONS_REQUEST_READ_SMS);
}
Handling permission resp. as follows;
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if (requestCode == PERMISSIONS_REQUEST_READ_SMS) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//Doing task regarding SMS permission.
}else if (grantResults[0] == PackageManager.PERMISSION_DENIED){
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.READ_SMS)) {
//Show an explanation to the user *asynchronously*
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("This permission is important to Read SMS.")
.setTitle("Important permission required");
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
ActivityCompat.requestPermissions(GenerateOTPActivity.this, new String[]{Manifest.permission.READ_SMS}, PERMISSIONS_REQUEST_READ_SMS);
}
});
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, PERMISSIONS_REQUEST_READ_SMS);
}else{
//Never ask again and handle your app without permission.
}
}
}
}
By default SMS permission is Granted so checkSelfPermission() reterns zero but when I manually deny permission from device setting then also checkSelfPermission() returns zero value.
I dont understand how to check SMS permission is denied or not. Please provide me some solutions.

try this codes and also provide permissions in android manifest
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
marshmallowPermission(); //***** marshmaloow runtime permission*****//
}
public Boolean marshmallowPermission(){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkPermission()) {
Toast.makeText(this,"Permission already granted.", Toast.LENGTH_SHORT).show();
} else {
requestPermission();
}
}
return true;
}
#TargetApi(Build.VERSION_CODES.M)
public boolean checkPermission(){
int sms = checkSelfPermission(android.Manifest.permission.READ_SMS);
if (sms == PackageManager.PERMISSION_GRANTED ){
return true;
} else {
return false;
}
}
#TargetApi(Build.VERSION_CODES.M)
public void requestPermission(){
if (shouldShowRequestPermissionRationale(android.Manifest.permission.READ_SMS)){
if(shouldShowRequestPermissionRationale(android.Manifest.permission.READ_SMS)){
Toast.makeText(this,"sms Permission must be needed which allows to access sms . Please allow sms in App Settings for additional functionality.",Toast.LENGTH_LONG).show();
}
Intent intent = new Intent();
intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", this.getPackageName(), null);
intent.setData(uri);
this.startActivity(intent);
} else {
requestPermissions(new String[]{android.Manifest.permission.READ_SMS},100);
}
}
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case 100:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this,"Permission Granted, Now you can access app without bug.",Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this,"Permission Denied, App maybe get crashed.", Toast.LENGTH_LONG).show();
}
break;
}
}

Android debugging on real device - MissingPermissionException [duplicate]

In Lollipop, the download functionality works fine in my app, but when I upgraded to Marshmallow, my app crashes and gives this error when I try to download from the internet into the SD card:
Neither user nor current process has android.permission.WRITE_EXTERNAL_STORAGE
It complains about this line of code:
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
I have the permissions in the manifest outside application:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
I cleaned and rebuilt the project, but it still crashes.

You should be checking if the user has granted permission of external storage by using:
if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
Log.v(TAG,"Permission is granted");
//File write logic here
return true;
}
If not, you need to ask the user to grant your app a permission:
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_CODE);
Of course these are for marshmallow devices only so you need to check if your app is running on Marshmallow:
if (Build.VERSION.SDK_INT >= 23) {
//do your check here
}
Be also sure that your activity implements OnRequestPermissionResult
The entire permission looks like this:
public boolean isStoragePermissionGranted() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED) {
Log.v(TAG,"Permission is granted");
return true;
} else {
Log.v(TAG,"Permission is revoked");
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
return false;
}
}
else { //permission is automatically granted on sdk<23 upon installation
Log.v(TAG,"Permission is granted");
return true;
}
}
Permission result callback:
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
Log.v(TAG,"Permission: "+permissions[0]+ "was "+grantResults[0]);
//resume tasks needing this permission
}
}

Android's permission system is one of the biggest security concern all
along since those permissions are asked for at install time. Once
installed, the application will be able to access all of things
granted without any user's acknowledgement what exactly application
does with the permission.
Android 6.0 Marshmallow introduces one of the largest changes to the
permissions model with the addition of runtime permissions, a new
permission model that replaces the existing install time permissions
model when you target API 23 and the app is running on an Android 6.0+
device
Courtesy goes to Requesting Permissions at Run Time .
Example
Declare this as Global
private static final int PERMISSION_REQUEST_CODE = 1;
Add this in your onCreate() section
After setContentView(R.layout.your_xml);
if (Build.VERSION.SDK_INT >= 23)
{
if (checkPermission())
{
// Code for above or equal 23 API Oriented Device
// Your Permission granted already .Do next code
} else {
requestPermission(); // Code for permission
}
}
else
{
// Code for Below 23 API Oriented Device
// Do next code
}
Now adding checkPermission() and requestPermission()
private boolean checkPermission() {
int result = ContextCompat.checkSelfPermission(Your_Activity.this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
if (result == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
return false;
}
}
private void requestPermission() {
if (ActivityCompat.shouldShowRequestPermissionRationale(Your_Activity.this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
Toast.makeText(Your_Activity.this, "Write External Storage permission allows us to do store images. Please allow this permission in App Settings.", Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(Your_Activity.this, new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, PERMISSION_REQUEST_CODE);
}
}
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Log.e("value", "Permission Granted, Now you can use local drive .");
} else {
Log.e("value", "Permission Denied, You cannot use local drive .");
}
break;
}
}
FYI
onRequestPermissionsResult
This interface is the contract for receiving the results for
permission requests.

Check multiple Permission in API level 23
Step 1:
String[] permissions = new String[]{
Manifest.permission.INTERNET,
Manifest.permission.READ_PHONE_STATE,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.VIBRATE,
Manifest.permission.RECORD_AUDIO,
};
Step 2:
private boolean checkPermissions() {
int result;
List<String> listPermissionsNeeded = new ArrayList<>();
for (String p : permissions) {
result = ContextCompat.checkSelfPermission(this, p);
if (result != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(p);
}
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), 100);
return false;
}
return true;
}
Step 3:
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
if (requestCode == 100) {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// do something
}
return;
}
}
Step 4:
in onCreate of Activity
checkPermissions();

Unless there is a definite requirement of writing on external storage, you can always choose to save files in app directory. In my case I had to save files and after wasting 2 to 3 days I found out if I change the storage path from
Environment.getExternalStorageDirectory()
to
getApplicationContext().getFilesDir().getPath() //which returns the internal app files directory path
it works like charm on all the devices.
This is because for writing on External storage you need extra permissions but writing in internal app directory is simple.

you need to use runtime permission in marshmallow
https://developer.android.com/training/permissions/requesting.html
you can check in app info -> permission
is your app get permission for write external storage or not

From marshmallow version, developers need to ask for runtime permissions to user.
Let me give you whole process for asking runtime permissions.
I am using reference from here : marshmallow runtime permissions android.
First create a method which checks whether all permissions are given or not
private boolean checkAndRequestPermissions() {
int camerapermission = ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA);
int writepermission = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
int permissionLocation = ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION);
int permissionRecordAudio = ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO);
List<String> listPermissionsNeeded = new ArrayList<>();
if (camerapermission != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.CAMERA);
}
if (writepermission != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
}
if (permissionLocation != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
}
if (permissionRecordAudio != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.RECORD_AUDIO);
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
return false;
}
return true;
}
Now here is the code which is run after above method. We will override onRequestPermissionsResult() method :
#Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
Log.d(TAG, "Permission callback called-------");
switch (requestCode) {
case REQUEST_ID_MULTIPLE_PERMISSIONS: {
Map<String, Integer> perms = new HashMap<>();
// Initialize the map with both permissions
perms.put(Manifest.permission.CAMERA, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.WRITE_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.RECORD_AUDIO, PackageManager.PERMISSION_GRANTED);
// Fill with actual results from user
if (grantResults.length > 0) {
for (int i = 0; i < permissions.length; i++)
perms.put(permissions[i], grantResults[i]);
// Check for both permissions
if (perms.get(Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED
&& perms.get(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED
&& perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
&& perms.get(Manifest.permission.RECORD_AUDIO) == PackageManager.PERMISSION_GRANTED) {
Log.d(TAG, "sms & location services permission granted");
// process the normal flow
Intent i = new Intent(MainActivity.this, WelcomeActivity.class);
startActivity(i);
finish();
//else any one or both the permissions are not granted
} else {
Log.d(TAG, "Some permissions are not granted ask again ");
//permission is denied (this is the first time, when "never ask again" is not checked) so ask again explaining the usage of permission
// // shouldShowRequestPermissionRationale will return true
//show the dialog or snackbar saying its necessary and try again otherwise proceed with setup.
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)
|| ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)
|| ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)
|| ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.RECORD_AUDIO)) {
showDialogOK("Service Permissions are required for this app",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case DialogInterface.BUTTON_POSITIVE:
checkAndRequestPermissions();
break;
case DialogInterface.BUTTON_NEGATIVE:
// proceed with logic by disabling the related features or quit the app.
finish();
break;
}
}
});
}
//permission is denied (and never ask again is checked)
//shouldShowRequestPermissionRationale will return false
else {
explain("You need to give some mandatory permissions to continue. Do you want to go to app settings?");
// //proceed with logic by disabling the related features or quit the app.
}
}
}
}
}
}
If user clicks on Deny option then showDialogOK() method will be used to show dialog
If user clicks on Deny and also clicks a checkbox saying "never ask again", then explain() method will be used to show dialog.
methods to show dialogs :
private void showDialogOK(String message, DialogInterface.OnClickListener okListener) {
new AlertDialog.Builder(this)
.setMessage(message)
.setPositiveButton("OK", okListener)
.setNegativeButton("Cancel", okListener)
.create()
.show();
}
private void explain(String msg){
final android.support.v7.app.AlertDialog.Builder dialog = new android.support.v7.app.AlertDialog.Builder(this);
dialog.setMessage(msg)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface paramDialogInterface, int paramInt) {
// permissionsclass.requestPermission(type,code);
startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:com.exampledemo.parsaniahardik.marshmallowpermission")));
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface paramDialogInterface, int paramInt) {
finish();
}
});
dialog.show();
}
Above code snippet asks for four permissions at a time. You can also ask for any number of permissions in your any activity as per your requirements.

The easiest way I found was
private boolean checkPermissions(){
if(ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
return true;
}
else {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, PERMISSION_CODE);
return false;
}
}

Add below code to your OnCreate() function in MainAcitivity, which will display pop up to ask for permission:
if (ActivityCompat.shouldShowRequestPermissionRationale(TestActivity.this,
Manifest.permission.WRITE_EXTERNAL_STORAGE)){
}
else {
ActivityCompat.requestPermissions(TestActivity.this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
100);
}

if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(),
Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
Log.d(TAG, "Permission granted");
} else {
ActivityCompat.requestPermissions(getActivity(),
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
100);
}
fab.setOnClickListener(v -> {
Bitmap b = BitmapFactory.decodeResource(getResources(), R.drawable.refer_pic);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/*");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
b.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(requireActivity().getContentResolver(),
b, "Title", null);
Uri imageUri = Uri.parse(path);
share.putExtra(Intent.EXTRA_STREAM, imageUri);
share.putExtra(Intent.EXTRA_TEXT, "Here is text");
startActivity(Intent.createChooser(share, "Share via"));
});

After lots of searching This code work for me:
Check the permission already has:
Check WRITE_EXTERNAL_STORAGE permission Allowed or not?
if(isReadStorageAllowed()){
//If permission is already having then showing the toast
//Toast.makeText(SplashActivity.this,"You already have the permission",Toast.LENGTH_LONG).show();
//Existing the method with return
return;
}else{
requestStoragePermission();
}
private boolean isReadStorageAllowed() {
//Getting the permission status
int result = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
//If permission is granted returning true
if (result == PackageManager.PERMISSION_GRANTED)
return true;
//If permission is not granted returning false
return false;
}
//Requesting permission
private void requestStoragePermission(){
if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE)){
//If the user has denied the permission previously your code will come to this block
//Here you can explain why you need this permission
//Explain here why you need this permission
}
//And finally ask for the permission
ActivityCompat.requestPermissions(this,new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE},REQUEST_WRITE_STORAGE);
}
Implement Override onRequestPermissionsResult method for checking is the user allow or denie
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
//Checking the request code of our request
if(requestCode == REQUEST_WRITE_STORAGE){
//If permission is granted
if(grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
//Displaying a toast
Toast.makeText(this,"Permission granted now you can read the storage",Toast.LENGTH_LONG).show();
}else{
//Displaying another toast if permission is not granted
Toast.makeText(this,"Oops you just denied the permission",Toast.LENGTH_LONG).show();
}
}

Before starting your download check your runtime permissions and if you don't have permission the request permissions like this method
requestStoragePermission()
private void requestStoragePermission(){
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
android.Manifest.permission.READ_EXTERNAL_STORAGE))
{
}
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
STORAGE_PERMISSION_CODE);
}
#Override
public void onRequestPermissionsResult(int requestCode,
#NonNull String[] permissions,
#NonNull int[] grantResults) {
if(requestCode == STORAGE_PERMISSION_CODE){
if(grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
}
else{
Toast.makeText(this,
"Oops you just denied the permission",
Toast.LENGTH_LONG).show();
}
}
}

In a simple way the permission can be granted using manifest.xml file, but it was ok till the api level 23 sdk version 6, after from here, if we want to get the permission we have to ask for the use to allow the permission which are needed.
Just add this code in the mainActivity.java
Override
public void onClick(View view) {
// Request the permission
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.CAMERA},
PERMISSION_REQUEST_CAMERA);
Replace CAMERA or add with WRITE_EXTERNAL_STORAGE if you want, and with the unique code.
new String[]{Manifest.permission.CAMERA,
Manifest.permission.WRITE_EXTERNAL_STORAGE},
101);
This is the simple code to get permission.

Marshmallow permissions should ask only if not already granted

I'm developing an app that require multiple permissions, so i added it and did marshmallow code too, but the problem is when i re-open an app in marshmallow it always ask for permission, i want to ask only if its not granted.
kindly help me to code for it, Thanks in Advance!

Just check for the permission and only request if neccessary.
Check permission with the help of
checkSelfPermission(Manifest.permission.READ_CONTACTS)
Check if permission is already granted or not
if (checkSelfPermission(Manifest.permission.READ_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.READ_CONTACTS},
MY_PERMISSIONS_REQUEST_READ_CONTACTS);
// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
// app-defined int constant
return;
}
Then handle the permission
#Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! do the
} else {
// permission denied, Disable the
// functionality that depends on this permission.
}
return;
}
}}

the Permission system has changed. But here is a good explanation how to deal with it properly.
https://developer.android.com/training/permissions/requesting.html
This way the dialog is only opened once if the user grants permission. If he declines you have a option to show a explanation the next time the permission is requested.
They also have a section with best practices that is worth to read:
https://developer.android.com/training/permissions/best-practices.html

Follow these steps :
Create a group of permission you need to access.
Pass the group/array to check permission granted or not
Sample code for your reference :
public static boolean hasPermissions(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) {
return false;
}
}
}
return true;
Above code will check your group of permissions later pass these all to ask for once
int PERMISSION_ALL = 1;
//create all permissions array
String[] PERMISSIONS = {Manifest.permission.READ_CONTACTS, //all your permissions};
//Now check whether permissions are granted or not
if(!hasPermissions(this, PERMISSIONS)){
ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}
Hope this will works out for you.

Application crashed after selecting contact from Contacts in android 6.0

From my activity when i call Contacts to get a contact number the application crashed. Application is running ok on other devices but when i'm try to run it in android 6.0, it crashed. i've no idea what i'm doing wrong.
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);
After getting the the data in onActivityResult method.
#Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
switch (reqCode) {
case (PICK_CONTACT) :
if (resultCode == Activity.RESULT_OK) {
Uri contactData = data.getData();
Cursor c = this.getContentResolver().query(contactData, null, null, null, null);
if (c.moveToFirst()) {
String contactId = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));
String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String phoneNumber = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
Log.d(TAG, "name : "+name+" , Phone Number : "+ phoneNumber);
}
}
break;
}
}
can Anyone help me ?

All of the answers here are wrong. You shouldn't need READ_CONTACT permission at all to retrieve single contact using ACTION_PICK intent. You should be granted this permission temporary to be able to retrieve contact specific data. However there are some devices that don't implement this API in a good way. Myself I have found Sony Xperia Z3, but I heard about HTC devices also had this problem.
To have the user select a contact and provide your app access to all the contact information, use the ACTION_PICK action and specify the MIME type to Contacts.CONTENT_TYPE.
The result Intent delivered to your onActivityResult() callback contains the content: URI pointing to the selected contact. The response grants your app temporary permissions to read that contact using the Contacts Provider API even if your app does not include the READ_CONTACTS permission.

[UPDATE]
After upgrading Sony Xperia Z3 system image to version 23.5.A.1.291 bug does not occur anymore.

From android 6.0 (Mashmello) , android has introduced Run Time Permissions for users to grand permission to apps while the app is running, not when they install the app. So, Your calling should be like this ->
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
/*If Android M*/
if (ContextCompat.checkSelfPermission(SendMoneyByDetailsActivity.this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
/*If Android M and Not permission granted */
ActivityCompat.requestPermissions(SendMoneyByDetailsActivity.this, new String[]{Manifest.permission.READ_CONTACTS}, REQUEST_READ_CONTACTS);
} else {
/*If Android M and permission granted */
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);
}
} else {
/*IF not Android M*/
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);
}
And when user grant the permission then you can call the intent to pick contact list ->
#Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case REQUEST_READ_CONTACTS: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//permission was granted, yay! Do the
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);
} else {
// permission denied
}
return;
}
}
}
And don't forgot to add permission in your manifest file.
<uses-permission android:name="android.permission.READ_CONTACTS" />

It not your manifest problem its problem with android 6.0 it requires Runtime Permissions...
after adding this in manifest
<uses-permission android:name="android.permission.READ_CONTACTS" />
Just change your code to this In your code..
public class MainActivity extends Activity {
public static final int REQUIRED_PERMISSIONS = 001;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
//give here permissions what ever you want...
// if you are using one add only one... not all..
if ((CheckPermission(this, Manifest.permission.READ_CONTACTS))&&
(CheckPermission(this, Manifest.permission.READ_PHONE_STATE))&&
(CheckPermission(this, Manifest.permission.INTERNET))&&
(CheckPermission(this, Manifest.permission.ACCESS_NETWORK_STATE))&&
(CheckPermission(this, Manifest.permission.ACCESS_WIFI_STATE)))
{
PermHandling();
}
//now reqest runtime permissions..
else {
RequestPermission(MainActivity.this, Manifest.permission.READ_CONTACTS, REQUIRED_PERMISSIONS);
RequestPermission(MainActivity.this, Manifest.permission.READ_PHONE_STATE, REQUIRED_PERMISSIONS );
RequestPermission(MainActivity.this, Manifest.permission.INTERNET, REQUIRED_PERMISSIONS );
RequestPermission(MainActivity.this, Manifest.permission.ACCESS_NETWORK_STATE, REQUIRED_PERMISSIONS );
RequestPermission(MainActivity.this, Manifest.permission.ACCESS_WIFI_STATE, REQUIRED_PERMISSIONS );
}
}
private void PermHandling() {
//Your app internal parts....
//Here your stuff works...
}
//private void NewPermHandling(){
//}
#Override
public void onRequestPermissionsResult(int permsRequestCode, String[] permissions, int[] grantResults) {
switch (permsRequestCode) {
case REQUIRED_PERMISSIONS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
PermHandling();
} else {
//Toast.makeText(this, "Please Grant Permissions other wise app will close.!", Toast.LENGTH_SHORT).show();
}
return;
}
}
}
public void RequestPermission(Activity thisActivity, String Permission, int Code) {
if (ContextCompat.checkSelfPermission(thisActivity,
Permission)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
Permission)) {
} else {
ActivityCompat.requestPermissions(thisActivity,
new String[]{Permission},
Code);
}
}
}
public boolean CheckPermission(Context context, String Permission) {
if (ContextCompat.checkSelfPermission(context,
Permission) == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
return false;
}
}
}
I also faced same problem my applications worked on till 5.1 but 6.0+ due to Runtime permissions We need to add them.. and accept those permissions at runtime

I think this is permission issue
add bellow permission inside manifest file
<uses-permission android:name="android.permission.READ_CONTACTS" />
accept permissions in marshmallows
https://developer.android.com/training/permissions/requesting.html
actual implementation
add bellow code inside Main Activity
call checkAndAddPermission() method inside onCreate() method
final private int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 1244;
private void checkAndAddPermission() {
List<String> permissionsNeeded = new ArrayList<>();
final List<String> permissionsList = new ArrayList<>();
if (!addPermission(permissionsList, android.Manifest.permission.READ_CONTACTS))
permissionsNeeded.add("ReadContacts");
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);
ActivityCompat.requestPermissions(MainActivity.this, permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
} else {
ActivityCompat.requestPermissions(MainActivity.this, permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
}
}
}
#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;
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch (requestCode) {
case REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS: {
Map<String, Integer> perms = new HashMap<>();
// Initial
perms.put(android.Manifest.permission.READ_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(android.Manifest.permission.READ_CONTACTS) == PackageManager.PERMISSION_GRANTED) {
// All Permissions Granted
} else {
// Permission Denied
Toast.makeText(MainActivity.this, "Some Permission is Denied", Toast.LENGTH_SHORT)
.show();
}
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}

SMS does not send in Marshmallow - android

The reason may be in MarshMallow we can turn off and on permissions for particular app. So check for permissions turned on or off before sending SMS.
