我正在开发一款简单的Android游戏,可以通过服务在后台播放声音。比赛开始时,声音很好。但是当按下音量增大键或向下按钮时,应用程序会立即退出。
public class PlayAudio extends Service{
private static final String LOGCAT = null;
MediaPlayer objPlayer;
public void onCreate(){
super.onCreate();
Log.d(LOGCAT, "Service Started!");
objPlayer = MediaPlayer.create(this,R.raw.relax);
}
public int onStartCommand(Intent intent, int flags, int startId){
objPlayer.start();
Log.d(LOGCAT, "Media Player started!");
if(objPlayer.isLooping() != true){
Log.d(LOGCAT, "Problem in Playing Audio");
}
return 1;
}
public void onStop(){
objPlayer.stop();
objPlayer.release();
}
public void onPause(){
objPlayer.stop();
objPlayer.release();
}
public void onDestroy(){
objPlayer.stop();
objPlayer.release();
}
@Override
public IBinder onBind(Intent objIndent) {
return null;
}
}
此代码开始播放声音
public void playAudio() {
Intent objIntent = new Intent(this, PlayAudio.class);
startService(objIntent);
}
答案 0 :(得分:0)
问题解决了。我错过了这个条件:
if (keyCode == KeyEvent.KEYCODE_BACK){}
