     @RuntimePermissions
     public class MainActivity extends AppCompatActivity {
  
     private AlertDialog alert = null;
     private AlertDialog.Builder builder = null;
  
     private Button btnRe;

        btnRe.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
