当Android屏幕锁定时，如何让html5音频继续播放HLS音频？

<audio controls autoplay>
  <source src="http://example.com/path/to/hls-audio.m3u8" type="application/x-mpegURL">
</audio>

<uses-permission android:name="android.permission.WAKE_LOCK" />

import android.os.PowerManager;
import android.content.Context;

public class MainActivity extends Activity {
  private PowerManager.WakeLock wakeLock;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    PowerManager powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
    wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyApp:WakeLock");
    wakeLock.acquire();
  }

  @Override
  protected void onDestroy() {
    super.onDestroy();
    if (wakeLock != null && wakeLock.isHeld()) {
      wakeLock.release();
      wakeLock = null;
    }
  }
}

@Override
protected void onPause() {
  super.onPause();
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
    if (wakeLock != null && wakeLock.isHeld()) {
      wakeLock.release();
      wakeLock.acquire();
    }
  }
}
