问题描述
我想打从Web服务的一首歌,我写了code如下
保护无效的onCreate(包savedInstanceState){
super.onCreate(savedInstanceState);
的setContentView(R.layout.content);
startButton =(的ImageButton)findViewById(R.id.start);
意向意图= getIntent();
mp3Path = intent.getStringExtra(mp3Path);
球员=新的MediaPlayer();
startButton.setOnClickListener(新OnClickListener(){
@覆盖
公共无效的onClick(视图v){
尝试 {
如果(玩家!= NULL)
player.stop();
player.setDataSource(mp3Path);
播放器prepare()。
player.start();
}赶上(IllegalStateException异常E){
e.printStackTrace();
}赶上(IOException异常E){
e.printStackTrace();
}
}
});
}
但是,当我点击该按钮,它会抛出以下异常,并告诉我大概有prepare错误:
04-13 17:23:13.186:E / MediaPlayer的(401):停止调用状态1
04-13 17:23:13.186:E / MediaPlayer的(401):错误(-38,0)
04-13 17:23:13.206:E / MediaPlayer的(401):错误(1,-2147483648)
04-13 17:23:13.206:W / System.err的(401):产生java.io.IOException:prepare失败:状态=为0x1
04-13 17:23:13.226:W / System.err的(401):在android.media.MediaPlayer prepare(本机方法)
04-13 17:23:13.226:W / System.err的(401):在com.Android.SampleActivity $ 1.onClick(SampleActivity.java:50)
解决方案
您需要实现流媒体播放器。下面是一个<一个href="http://davanum.word$p$pss.com/2007/12/29/android-videomusic-player-sample-from-local-disk-as-well-as-remote-urls/"相对=nofollow>为例的。希望它会帮助你。
I want to play a song from web service, and I wrote code as follow
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content);
startButton = (ImageButton) findViewById(R.id.start);
Intent intent = getIntent();
mp3Path = intent.getStringExtra("mp3Path");
player = new MediaPlayer();
startButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
try {
if(player != null)
player.stop();
player.setDataSource(mp3Path);
player.prepare();
player.start();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
But when I click that button, it throws the following exception and I'm told there are errors about prepare:
04-13 17:23:13.186: E/MediaPlayer(401): stop called in state 1
04-13 17:23:13.186: E/MediaPlayer(401): error (-38, 0)
04-13 17:23:13.206: E/MediaPlayer(401): error (1, -2147483648)
04-13 17:23:13.206: W/System.err(401): java.io.IOException: Prepare failed.: status=0x1
04-13 17:23:13.226: W/System.err(401): at android.media.MediaPlayer.prepare(Native Method)
04-13 17:23:13.226: W/System.err(401): at com.Android.SampleActivity$1.onClick(SampleActivity.java:50)
