我添加了startForeground服务,但同样的问题.当我退出应用程序时,服务停止,而不是重新启动版本2.3.3甚至我看到notification.But phoneStateListener取空值
如何确保退出应用程序时,服务不会停止

//application main metod
@Override
protected void onCreate(Bundle savedInstanceState) {              
//.....

    startService(new Intent(getApplicationContext(),MyPhoneStateListener.class));
}




 @Override
 public int onStartCommand(Intent intent,int flags,int startId)
 {
    setCallListener();    
    setNoti();
    return START_STICKY;
 }

 private void setCallListener()
 {
        try
        {
            if (phoneStateListener==null)
            {

              phoneStateListener = new StateListener();
              telephonymanager = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
                 telephonymanager.listen(phoneStateListener,PhoneStateListener.LISTEN_CALL_STATE);
            }
        }
        catch(Exception ex)
        { 

        }
    }

private void setNoti()
{

Notification notification= new Notification(R.drawable.ic_launcher,getResources().getString(R.string.app_name),System.currentTimeMillis());

    Intent main = new Intent(this,MainActivity.class);

    main.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(this,main,PendingIntent.FLAG_UPDATE_CURRENT);

    notification.setLatestEventInfo(this,getResources().getStringArray(R.array.blockstate)[Sabitler.ShieldState].toString(),pendingIntent);

    notification.flags |= Notification.FLAG_FOREGROUND_SERVICE | Notification.FLAG_NO_CLEAR;

    startForeground(123456,notification);  
}

我改变了设置callstatelistener从服务到广播的地方,正如Dhawal Sodha所建议的那样,但在这种情况下阻止不需要的呼叫变得缓慢.我想在广播TelephonyManager初始化每个调用.以下广播代码.当我使用服务时,
当主要活动退出时,服务在版本2.3.3中停止.任何的想法 ？广播还是服务？如何让播放速度更快？每个调用变量和对象在广播中再次初始化.

public class PhoneStateBroadcastReceiver extends BroadcastReceiver{

    MyCustomStateListener myCustomStateListener;
    TelephonyManager telephonymanager;
    @Override
    public void onReceive(Context context,Intent intent) 
    {
        try
        {
            //Log.e("receiver1",String.valueOf(System.currentTimeMillis()));

            telephonymanager = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE);
            myCustomStateListener = new MyCustomStateListener(context,telephonymanager);
            telephonymanager.listen(myCustomStateListener,PhoneStateListener.LISTEN_CALL_STATE);
            //Log.e("receiver2",String.valueOf(System.currentTimeMillis()));
            telephonymanager.listen(myCustomStateListener,PhoneStateListener.LISTEN_NONE);
        }
        catch(Exception ex)
        { 
            Toast.makeText(context,"setCallListener:"+ex.toString(),Toast.LENGTH_SHORT).show();
        }
    }   
}
