如何在最低sdk为9的android项目中使用google exo player？

implementation 'com.google.android.exoplayer:exoplayer:2.X.X'

<com.google.android.exoplayer2.ui.PlayerView
    android:id="@+id/player_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

// 初始化ExoPlayer
SimpleExoPlayer player = new SimpleExoPlayer.Builder(context).build();
PlayerView playerView = findViewById(R.id.player_view);
playerView.setPlayer(player);

// 创建媒体数据源
Uri uri = Uri.parse("视频文件的URL或本地路径");
MediaSource mediaSource = new ProgressiveMediaSource.Factory(new DefaultDataSourceFactory(context, "ExoPlayer"))
        .createMediaSource(uri);

// 准备播放器
player.prepare(mediaSource);
player.setPlayWhenReady(true);

@Override
protected void onStart() {
    super.onStart();
    player.setPlayWhenReady(true);
}

@Override
protected void onStop() {
    super.onStop();
    player.setPlayWhenReady(false);
}

@Override
protected void onDestroy() {
    super.onDestroy();
    player.release();
}
