我正在尝试使用下面的代码在我的应用程序中播放音乐，当我在(Android 8.0，7.0，5.0)上测试时它工作正常但是当我在 Android 9.0 上测试时，它不起作用，看起来RadioService 不起作用，它告诉我出了点问题!! Toast 所以调用了 onPlayerError
public void onPlayerError(ExoPlaybackException error) {
EventBus.getDefault().post(PlaybackStatus.ERROR);
}
MainActivity.java
@Subscribe
public void onEvent(String status) {
switch (status) {
case PlaybackStatus.LOADING:
progressloading.setVisibility(View.VISIBLE);
trigger.setVisibility(View.GONE);
break;
case PlaybackStatus.ERROR:
Toast.makeText(this, "Something went wrong!!", Toast.LENGTH_SHORT).show();
break;
}
if (status.equals(PlaybackStatus.PLAYING)) {
trigger.setVisibility(View.VISIBLE);
progressloading.setVisibility(View.GONE);
}
trigger.setImageResource(status.equals(PlaybackStatus.PLAYING)
? R.drawable.ic_pause_black
: R.drawable.ic_play_arrow_black);
}
，谁能帮我解决这个问题。
