утечка памяти в компоненте ExoPlayer с учетом жизненного цикла (настраиваемое представление с учетом жизненного цикла) с рекламой VAST

извините за мой плохой Engli sh, я хочу сделать пользовательский просмотр поверх Google \ ExoPlayer , который

  • можно повторно использовать просто в нескольких разделах одного и того же Фрагмент или действие.
  • имеет пользовательский интерфейс управления воспроизведением (воспроизведение, пауза, полноэкранный режим, скорость, селектор качества, регуляторы яркости, регуляторы громкости)
  • обрабатывает само миниатюру
  • Включить рекламную систему VAST.
  • с учетом жизненного цикла (обрабатывать сам жизненный цикл)

это наш код:

https://github.com/alaatv/android-alaatv-exoplayer/blob/master/java/com/alaatv/component/player/AlaaTV.java

когда мы хотим использовать его во фрагменте, xml код: 

<androidx.cardview.widget.CardView
                    android:id="@+id/intro_video"
                    android:layout_width="0dp"
                    android:layout_height="wrap_content"
                    android:layout_marginStart="10dp"
                    android:layout_marginTop="@dimen/margin_10dp"

                        android:layout_height="wrap_content">

                        <com.alaatv.component.player.AlaaTV
                            android:id="@+id/card_alaatv_player_intro_video"
                            android:layout_width="match_parent"
                            android:layout_height="200dp"

                            custom:product_introduction_video="true"

                            />


                        <androidx.appcompat.widget.AppCompatImageView
                            android:id="@+id/card_alaatv_intro_video_ic"

                            app:layout_constraintTop_toTopOf="parent" />

                    </androidx.constraintlayout.widget.ConstraintLayout>

</androidx.cardview.widget.CardView>

и во фрагменте - java код: 

....
    @Override
    public void onViewCreated( @NonNull View view, @Nullable Bundle savedInstanceState ) {
        super.onViewCreated(view, savedInstanceState);
        ....
        mBinding.cardAlaatvPlayerIntroVideo.observe(getViewLifecycleOwner().getLifecycle());
        mBinding.cardAlaatvPlayerIntroVideo.setVastUrl("https://alaatv.com/vast.xml");
        mBinding.cardAlaatvIntroVideoIc.setVisibility(View.GONE);
        mBinding.cardAlaatvPlayerIntroVideo.setVideoUrls(introVideoUrl, introVideoUrl, introVideoUrl);
        mBinding.cardAlaatvPlayerIntroVideo.setVisibility(View.VISIBLE);
        mBinding.cardAlaatvPlayerIntroVideo.setPoster(videoPosterLink);
        mBinding.cardAlaatvPlayerIntroVideo.invalidate();
    }
    @Override
    public void onDestroyView( ) {
        super.onDestroyView();
        mBinding = null;
    }
...

Жизненный цикл ручки игрока включен :

и

https://github.com/alaatv/android-alaatv-exoplayer/blob/master/java/com/alaatv/component/player/AlaaTV.java

автоматически.

все в порядке, но с пакетом утечек:
