当我尝试通过 Medialayer 播放流音乐时，我会收到此消息：

但是在onPreparedListener播放开始后的2-5分钟内。
对于测试我创建了一个只有MediaPlayer的新项目并再次测试 - 同样的问题，但在其他应用程序（在线广播，在线音乐）上所有工作完美，测试不同的应用程序。
P.S。早期所有工作都很好，我认为它是Android 5的错误，因为在Android 4. *工作得很好（10-20秒后开始播放）也在模拟器播放后开始onPreparedListener

答案 0 :(得分：1)
你以错误的方式编写代码，你会播放你流式传输的音乐
String url = "http://stream6.radiostyle.ru:8006/priboyfm";
MediaPlayer mPlayer
Buuton buttonPlay = (Button) findViewById(R.id.play);
buttonPlay.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// editing
if(mPlayer == null){
mPlayer = new MediaPlayer();
}
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mPlayer.setDataSource(url);
} catch (IllegalArgumentException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
} catch (SecurityException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
try {
mPlayer.prepare();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
}
mPlayer.start();
}
});
//更新答案
private void play_music_onReady(){
// pass your url here
MediaPlayer mp = MediaPlayer.create(getApplicationContext(), Uri.parse(url));
mp.setOnPreparedListener(new OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
