//Add this method to show Dialog when the required permission has been granted to the app.
@Override
public void onRequestPermissionsResult(int requestCode,@NonNull String permissions[],@NonNull int[] grantResults) {
switch (requestCode) {
case FilePickerDialog.EXTERNAL_READ_PERMISSION_GRANT: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if(dialog!=null)
{ //Show dialog if the read permission has been granted.
dialog.show();
}
}
