How to check Grants Permissions at Run-Time?

Question

In Android M (Preview) the user can choose a specific app and retreive specific permission.

So I am asking How to check Grants Permissions at Run-Time?

Answer 1

Nice !!

I just found my need we can check if the permission is granted by :

checkSelfPermission(Manifest.permission.READ_CONTACTS) 

Request permissions if necessary

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;     } 

Handle the permissions request response

@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                 // calendar task you need to do.              } else {                  // permission denied, boo! Disable the                 // functionality that depends on this permission.             }             return;         }          // other 'switch' lines to check for other         // permissions this app might request     } }

Try this instead simple request code

public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;  private  boolean checkAndRequestPermissions() {     int camera = ContextCompat.checkSelfPermission(this, android.Manifest.permission.CAMERA);     int storage = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);     int loc = ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION);     int loc2 = ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION);     List<String> listPermissionsNeeded = new ArrayList<>();      if (camera != PackageManager.PERMISSION_GRANTED) {         listPermissionsNeeded.add(android.Manifest.permission.CAMERA);     }     if (storage != PackageManager.PERMISSION_GRANTED) {         listPermissionsNeeded.add(android.Manifest.permission.WRITE_EXTERNAL_STORAGE);     }     if (loc2 != PackageManager.PERMISSION_GRANTED) {         listPermissionsNeeded.add(android.Manifest.permission.ACCESS_FINE_LOCATION);     }     if (loc != PackageManager.PERMISSION_GRANTED) {         listPermissionsNeeded.add(android.Manifest.permission.ACCESS_COARSE_LOCATION);     }     if (!listPermissionsNeeded.isEmpty())     {         ActivityCompat.requestPermissions(this,listPermissionsNeeded.toArray                 (new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);         return false;     }     return true; }
