About coding

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }

    public void requestPermission(View view) {
        PermissionManager.request(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE});
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        Log.e(TAG, "onRequestPermissionsResult()");
