Android Studio 3.4

public class SubscribesFragment extends SubscribesBaseFragment {

 @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        if (context instanceof Activity) {
            mActivity = (Activity) context;
        }
}
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, final Intent intent) {
            // Get extra data included in the Intent
            String action = intent.getAction();
            if (action.equals(ExistSubscribeWidget.ACTION_REFUSE_PAPER_INVOICE)) {
                String providerGUID = intent.getStringExtra(ProviderWidget.EXTRA_PROVIDER_TAG);
                String notificationSubscribeOwnerKey = intent.getStringExtra(ExistSubscribeWidget.NOTIFICATION_SUBSCRIBE_OWNERkEY);
                showConfirmDialogRefusePaperInvoice(context, providerGUID, notificationSubscribeOwnerKey);
            }
        }
    };

    private void showConfirmDialogRefusePaperInvoice(Context context, final String providerGUID, final String notificationSubscribeOwnerKey) {
        final Activity actitivity = mActivity;
        AlertDialog.Builder builder = new AlertDialog.Builder(actitivity);
        builder.setTitle(R.string.refuse_paper_dialog_title);
        View customView = AndroidUtil.getLinearLayout(actitivity, R.layout.refuse_paper_dialog);
        builder.setView(customView);
        builder.setPositiveButton(R.string.ok, new android.content.DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
              //some code
            }
        });
        builder.setNegativeButton(R.string.cancel, new android.content.DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {

            }
        });
        AlertDialog dialog = builder.create();
        dialog.setCanceledOnTouchOutside(true);
        dialog.show(); // crash here
    }

}
