我正在开发一个应用程序，即时通讯使用Exoplayer库替代android的videoview。 exoplayer抛出这些警告

当我从屏幕上滚动视频时，直到调用onPause或onStop并且这些警告显示在Logcat中之后，视频才会再次显示（显示黑屏）。 我已经尝试调试，但到目前为止没有任何发现。请帮助我坚持这一点。 继承人的xml
<com.devbrackets.android.exomedia.ui.widget.VideoView
android:id="@+id/video_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="false"
app:useDefaultControls="true" />
和Java代码
videoView.setVideoPath(post.getPostVideo());
videoView.setOnPreparedListener(new OnPreparedListener() {
@Override
public void onPrepared() {
videoView.start();
}
});
