Не удалось расширить RemoteViews: MediaSessionCompat и NotificationCompat.MediaStyle на устройствах HUAWEI
Мое приложение падает, когда я пытаюсь отобразить уведомление на моем устройстве HUAWEI P8 lite под управлением Android 5.0.1 (он отлично работает на устройствах Nexus и Samsung). Большая часть моего кода взята из видео Media Media в правильном направлении (Big Android BBQ 2015) Яна Лейка. Весь мой код находится в службе Android. Если я удалю код:
builder.setStyle(new android.support.v7.app.NotificationCompat.MediaStyle()
.setShowActionsInCompactView(0, 1)
.setMediaSession(mMediaSessionCompat.getSessionToken()).setShowCancelButton(true)
.setCancelButtonIntent(MediaStyleHelper.getActionIntent(this, KeyEvent.KEYCODE_MEDIA_STOP)));
Затем приложение не сбой и уведомление отображается с изображением и заголовком. Но кнопки Media Action отсутствуют.
