Android Marshmallow includes a new functionality to let users accept or denied permissions when running an app instead of granting them all when installing it. This approach gives the user more control over applications but requires developers to add lots of code to support it.

droid-Runtime Permission is an Android sample project that simplifies the process of requesting permissions at runtime.

Usage

To start using this sample project you just need to extends RuntimePermissionActivity :

public class PermissionSampleActivity extends RuntimePermissionActivity {
   ...
 }

Single permission

For each single permission :

if (ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
    askRequestPermissions(new String[]{Manifest.permission.READ_CONTACTS}, R.string.enable_permission, REQUEST_CONTACT_PERMISSIONS);
} else {
    // Permission already granted. 
    // add your logic
}

Multiple permissions

For each group permission :

if ((ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED)
     || (ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)
     || (ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED)) {
     askRequestPermissions(new String[]{Manifest.permission.READ_CONTACTS, Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE},
             R.string.enable_permission, REQUEST_GROUP_PERMISSIONS);
} else {
      // Permission already granted. 
      // add your logic
}

Permission Granted

After granting permission write down your method or custom code :

@Override
    public void onRequestPermissionsGranted(int requestCode) {
        switch (requestCode) {
            // Single permission granted
            case REQUEST_CONTACT_PERMISSIONS:
                //TODO Add your logic
                break;
            
            // Group permission granted
            case REQUEST_GROUP_PERMISSIONS:
                //TODO Add your logic
                break;
        }
    }
