Permission grant flow

Check -> Request -> Grant

Check

Check permission status

// In Activity int permission = ContextCompat.checkSelfPermission( this, Manifest.permission.WRITE_EXTERNAL_STORAGE );

if (permission != PackageManager.PERMISSION_GRANTED) { // not granted} else { // granted or pre-Marshmallow}

Request

Request permission

if ( ActivityCompat.shouldShowRequestPermissionRationale( this, Manifest.permission.WRITE_EXTERNAL_STORAGE ) ) { // should show rationale} else { // needs request permission ActivityCompat.requestPermissions( this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, PERMISSION_REQUEST_CODE );}

Grant

Check permission granted

// In Activity @Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); if (requestCode == PERMISSION_REQUEST_CODE) { int grantResult = grantResults[0]; String statusString = toStatusString(grantResult); statusTextView.setText(statusString); if ( grantResults.length > 0 && grantResult == PackageManager.PERMISSION_GRANTED ) { // granted } else { // not granted } }}
