Utiliser Unity comme sous-vue me donne un écran noir

J'utilise Unity avec Android et cela fonctionne lorsque la vue est en plein écran, mais lorsque je la transforme en sous-vue, l'écran n'affiche rien.

Cela fonctionne en plein écran:

Intent intent = new Intent(this, UnityPlayerActivity.class);
intent.putExtra("arguments", "data from android");
startActivity(intent);

Ces questions sont également sans réponse:

J'ai essayé les solutions dont ils disposent, mais aucune ne semble avoir fonctionné.

Mon manifeste MainActivity / Unity actuel:

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

        m_UnityPlayer = new UnityPlayer(this);
        int glesMode = m_UnityPlayer.getSettings().getInt("gles_mode", 1);
        boolean trueColor8888 = false;
        m_UnityPlayer.init(glesMode, trueColor8888);

        setContentView(R.layout.activity_main);

        FrameLayout layout = (FrameLayout) findViewById(R.id.frameLayout2);
        LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
        layout.addView(m_UnityPlayer.getView(), 0, lp);
    }

vous pouvez y parvenir en utilisant uniquement la disposition du cadre, MainActivitydevrait être étendu comme Activitynon UnityPlayerActivity. Ajoutez ces deux lignes à l'activité dans le AndroidManifest.xml.

<meta-data android:name="unityplayer.UnityActivity" android:value="true" />
<meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="false" />
