[英]Android stream live audio
I am currently making an app that plays live radio. 我目前正在制作一个可以播放直播的应用。 I made a button in my MainActivity class, which starts the play service like so:
我在MainActivity类中创建了一个按钮,如下所示启动了播放服务:
Intent intent = new Intent(MainActivity.this, StreamRadio.class);
startService(intent);
Here is the code in my StreamRadio class. 这是我的StreamRadio类中的代码。
public class StreamRadio extends Service implements MediaPlayer.OnErrorListener {
private static final String TAG = "Information progress";
public MediaPlayer mediaPlayer;
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setDataSource("http:/xx.xx.xxx.xxx:xxxx/");
Log.d(TAG, "Connected to http:/xx.xx.xxx.xxx:xxxx");
mediaPlayer.prepareAsync();
Log.d(TAG, "Preparing Async");
} catch (IOException e) {
Log.e("TAG", "IOException");
}
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
Log.d(TAG, "Mediaplayer prepared");
mediaPlayer.start();
}
});
Log.d(TAG, "Nearly finished");
return START_STICKY;
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public boolean onError(MediaPlayer mp, int what, int extra) {
return false;
}
@Override
public void onDestroy() {
super.onDestroy();
Log.d(TAG, "Service is destroyed");
if (mediaPlayer != null) {
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
}
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer = null;
}
}
}
When the button in MainActivity is clicked again, the service is stopped. 当再次单击MainActivity中的按钮时,该服务将停止。
The service gets started and destroyed on click. 该服务将启动并在单击时销毁。 This is the logcat output (physical device):
这是logcat输出(物理设备):
02-03 09:42:05.719 9318-9318/ D/Information progress: Connected to http:/81.18.165.234:8361
02-03 09:42:05.719 9318-9318/ D/Information progress: Preparing Async
02-03 09:42:05.719 9318-9318/ D/Information progress: Nearly finished
02-03 09:42:05.729 9318-9318/ E/MediaPlayer: Error (1,-1)
On an emulator I get this error: 在模拟器上,我得到此错误:
02-03 10:08:26.054 2797-2797/ D/Information progress: Connected to http:/81.18.165.234:8361
02-03 10:08:26.055 2797-2797/ D/Information progress: Preparing Async
02-03 10:08:26.056 2797-2797/ D/Information progress: Nearly finished
02-03 10:08:26.060 2797-2808/ E/MediaPlayer: error (1, -2147483648)
02-03 10:08:26.060 2797-2797/ E/MediaPlayer: Error (1,-2147483648)
So I guess my question is as follows: Why is prepareAsync not working correctly, since there's no logcat message "Mediaplayer prepared", and how can I solve this? 因此,我想我的问题如下:为什么因为没有logcat消息“ Mediaplayer ready”,所以prepareAsync为什么不能正常工作,我该如何解决呢? I gave the app internet permission in the manifest.
我在清单中授予了应用Internet许可。 Other problems on SO don't seem to be the same as mine.
SO上的其他问题似乎与我的不同。
Thanks in advance! 提前致谢!
I think the issue is in your datasource , check if you are assigning "Stream URL" to your datasource. 我认为问题出在您的数据源中 ,请检查是否要为数据源分配“流URL” 。 eg http://live.streamtheworld.com:80/WXYZFMMOBILECMP3
例如http://live.streamtheworld.com:80/WXYZFMMOBILECMP3
