J it only takes a minute:
While I use almost the same code to play two videos, the first works perfectly, but the second does not.
When I press the next video button, the program crashed with:
WARN/System.err(15726): java.lang.IllegalStateException
WARN/System.err(15726):
at android.media.MediaPlayer.setDataSource(Native Method)
Source code:
the first play code:
mediaPlayer = new MediaPlayer();
playURI = receiveIntent.getStringExtra("playURI");
showDebugInfo("play uri "+playURI);
Log.e("Gplayer on create", "play uri "+playURI);
mediaPlayer.setDataSource(playURI);
} catch (IllegalArgumentException e) {
Log.v(LOGTAG, e.getMessage());
} catch (IllegalStateException e) {
Log.v(LOGTAG, e.getMessage());
} catch (IOException e) {
Log.v(LOGTAG, e.getMessage());
when press next button it runs the following code:
String uri = listAdapter.getItem(position).getItem().getFirstResource().getValue();
showDebugInfo(" Uri "+uri);
if(mediaPlayer != null){
mediaPlayer.stop();
mediaPlayer.reset();
mediaPlayer.setDataSource(uri);
mediaPlayer.prepareAsync();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Why does this happen? and I check the two parts only the different that, the first one is new a mediaplayer and the second is let the mediaplayer stop and reset then the same.
Know someone who can answer?

当我使用Android中MediaPlayer播放网络uri提供的一首歌曲时，出现如上的问题，这个问题的解决是因为没有获取相应的播放权限导致的。解决办法：需要在AndroidMani
当我使用Android中MediaPlayer播放网络uri提供的一首歌曲时，出现如上的问题，这个问题的解决是因为没有获取相应的播放权限导致的。解决办法：需要在AndroidManifest.xml中添加这样一段代码用于获取播放权限来访问你的manifest
file文件。
&uses-permission android:name=&android.permission.INTERNET& /&
网络播放指定Url提供的歌曲的代码如下：
& & * 网络资源
& & MediaPlayer&mediaPlayer=new MediaPlayer();
& & String path=&?link=/data2/music/61128.mp3?xcode=fc3ef977c9fa9bdff2550e&song_id=2923710&;
& & mediaPlayer.setDataSource(path);//为MediaPlayer设置数据源
& & mediaPlayer.prepare();//准备播放
& & mediaPlayer.start();//开始播放
