Android - Little dialog box appears after closing a dialog fragment

I've made this simple dialog fragment to display over the home screen, which works fine except when I dismiss the fragment dialog, a second little box appears with the word Dialogue in it. I can't for the life of me figure where its coming from.

Anyone have any suggestions? Could it be something to do with the chain of classes being called and that one of them is launching the alert again but without the custom layout view?

enter image description here

The dialog fragment.

public class DialogFragmentTest extends DialogFragment implements View.OnClickListener{

private AlertDialog.Builder mBuilder;
private AlertDialog mAlertDialog;
private View mDialogView;
private Button mOkBtn, mCancelBtn;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    mDialogView = inflater.inflate(R.layout.dialog_layout, container, false);

    Log.d("DialogFrag", "onCreate");

   // mBuilder = new AlertDialog.Builder(getContext());

    mOkBtn = (Button) mDialogView.findViewById(R.id.ok);
    mCancelBtn = (Button) mDialogView.findViewById(R.id.cancel);

    mOkBtn.setOnClickListener(this);
    mCancelBtn.setOnClickListener(this);

    return mDialogView;
}


@Override
public void onClick(View view) {
    switch (view.getId()) {
        case R.id.ok:

            this.dismiss();

            break;
        case R.id.cancel:
            this.dismiss();
            break;
    }
}

}

Dialog Receiver class.

public class AlertDialogReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    Intent alarmIntent = new Intent("android.intent.action.MAIN");
    alarmIntent.setClass(context, AlarmDialogClass.class);
    alarmIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(alarmIntent);
}
}

The class that instantiates the fragment.

public class AlarmDialogClass extends Activity {

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

    Log.d("AlarmClass", "onCreate:");

    FragmentManager fm = getFragmentManager();
    FragmentTransaction ft = fm.beginTransaction();
    DialogFragmentTest dft = new DialogFragmentTest();
    dft.show(fm, "Sample Fragment");


}

}

manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.android.shnellers.dialogue"
      xmlns:android="http://schemas.android.com/apk/res/android">

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
    <activity
        android:name=".AlarmDialogClass"
        android:theme="@android:style/Theme.Dialog"
        android:launchMode="singleInstance" />

    <receiver android:process=":remote" android:name=".AlertDialogReceiver"/>
</application>

It's the AlarmDialogClass Activity. Even though you don't call setContentView(), its window is still created, and with the Theme.Dialog, that's what it'll look like.

Finishing the Activity as soon as the DialogFragment is dismissed would take care of it, though that's a little unwieldy, and you might still see the Activity for a split second before it goes. You could instead use a NoDisplay theme for the Activity, but you'd still have to handle finishing the Activity after the DialogFragment is dismissed.

It's probably easier to just use the Activity itself as your dialog, and drop the DialogFragment.
