Instead of creating a new transparent activity, Use the SYSTEM_ALERT_WINDOW permission to do this

public void onReceive(Context ctx, Intent intent) {

    View popup = inflater.inflate(R.layout.mypopup, null, false);
    CustomDialog dialog = new CustomDialog(ctx, popup );

    dialog.getWindow().getAttributes().windowAnimations = R.style.PauseDialogAnimation;
    dialog.show();
}
