任何加速此代码的方法.流媒体音频Android

从网站制作应用和流媒体音频.我有一个菜单,当我点击按钮打开收音机活动时,它可能需要8-20秒才能加载,有时会强制关闭.任何帮助都会非常棒,谢谢.

码：

  public class Radio extends Activity {

private MediaPlayer mp;
private ImageButton pauseicon;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.player_1);

    pauseicon = (ImageButton) findViewById(R.id.pauseicon);
    getActionBar().setDisplayHomeAsUpEnabled(true);

    /**
     * Play button click event plays a song and changes button to pause
     * image pauses a song and changes button to play image
     * */

    String res = "http://216.235.91.36/play?s=magic24point7&d=LIVE365&r=0&membername=&session=magic24point7:0&AuthType=NORMAL&app_id=live365%3ABROWSER&SaneID=24.79.96.172-13316781890137014897763&tag=live365";

    mp = new MediaPlayer();
    try {
        mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
        mp.setDataSource(res);
        mp.prepare();
        mp.start();

    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (IllegalStateException e) {
        e.printStackTrace();
    } catch (IOException e) {

    }



    pauseicon.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            // No need to check if it is pauseicon

            if (mp.isPlaying()) {
                mp.pause();
                ((ImageButton) v).setImageResource(R.drawable.playicon);

            } else {
                mp.start();
                ((ImageButton) v).setImageResource(R.drawable.pauseicon);
            }
        }
    });

}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case android.R.id.home:
        NavUtils.navigateUpFromSameTask(this);

        if (mp != null)
            if (mp.isPlaying())
                mp.stop();

        mp.release();

        return true;
    default:
        return super.onOptionsItemSelected(item);

    }
}

@Override
public void onBackPressed() {
    if (mp != null) {
        if (mp.isPlaying())
            mp.stop();

        mp.release();
    }

    // there is no reason to call super.finish(); here
    // call super.onBackPressed(); and it will finish that activity for you
    super.onBackPressed();

}

 }

解决方法:

使用prepareAsync()和setOnPreparedListener()而不是prepare(). prepare()阻止UI线程,直到它返回,不推荐用于流.这可能是导致您崩溃的原因.

mp = new MediaPlayer();
try {
    mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
    mp.setDataSource(res);
    mp.setOnPreparedListener(new OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer player) {
            mp.start();
        }
    });
    mp.prepareAsync();
} catch (IllegalArgumentException e) {
    e.printStackTrace();
} catch (IllegalStateException e) {
    e.printStackTrace();
} catch (IOException e) {

}

http://developer.android.com/reference/android/media/MediaPlayer.html#prepare()

Prepares the player for playback, synchronously. After setting the datasource and the display surface, you need to either call prepare() or prepareAsync(). For files, it is OK to call prepare(), which blocks until MediaPlayer is ready for playback.

否则我认为网络是你的瓶颈.加快速度的最快方法是确保您的服务器/客户端通信快速.您的代码似乎没有任何内在的缓慢.
