库源与使用ExoPlayer的ImaAdsLoader类的字节码不匹配

Question

同时显示带有IMA扩展名和ProgressiveMediaSource的广告时，出现以下错误。前置广告完成后，应用程序崩溃了。导航到类ImaAdsLoader时，出现错误“库源与类ImaAdsLoader的字节码不匹配”

java.lang.NoSuchMethodError: No virtual method getAdGroupIndexAfterPositionUs(J)I in class Lcom/google/android/exoplayer2/source/ads/AdPlaybackState; or its super classes (declaration of 'com.google.android.exoplayer2.source.ads.AdPlaybackState' appears in /data/app/com.example.exomedia-pEwo-P6MjYGRL3PeKbTLiw==/base.apk)

重现步骤 ：使用以下视差

implementation 'com.google.android.exoplayer:exoplayer-core:2.10.7'
    implementation 'com.google.android.exoplayer:exoplayer-ui:2.10.7'
    implementation 'com.google.android.exoplayer:extension-ima:2.9.6'

并使用以下代码启动播放：

   player=ExoPlayerFactory.newSimpleInstance(this,DefaultTrackSelector())
    player_view.player=player
    adsLoader?.setPlayer(player)


    val dataSourceFactory = DefaultDataSourceFactory(
        this,
        "ExoDemo")

    val mediaSource:MediaSource=ProgressiveMediaSource.Factory(dataSourceFactory)
        .createMediaSource(Uri.parse(resources.getString(R.string.media_url_mp4)))

    val adsMediaSource = AdsMediaSource(mediaSource, dataSourceFactory, adsLoader, player_view)


    player?.prepare(adsMediaSource)
    player?.setPlayWhenReady(true)

使用以下版本的库并使用ExtractorMediaSource，可以正常运行：

implementation 'com.google.android.exoplayer:exoplayer-core:2.9.6'
    implementation 'com.google.android.exoplayer:exoplayer-ui:2.9.6'
    implementation 'com.google.android.exoplayer:extension-ima:2.9.6'

我终于发现extension_ima的版本必须与所使用的ExoPlayer库的版本匹配。或者，可以克隆ExoPlayer存储库并在本地依赖该模块。
