Android 呼叫接收器的PhoneStateListener在实际设备中不工作

我已经创建了

BroadCastReceiver

，它监听

IncomingCall

和

Outgoing Calls

。尝试在

BroadCastReceiver

中使用

TelephonyManager

添加

PhoneStateListener

，这在Emulator和某些设备上非常有效

它不适用于

三星ST 7652

。始终返回

呼叫状态\u IDLE

和传入号码

null

。为什么会这样

详情如下:

public class ReceiverInComingCall extends BroadcastReceiver { 
   public void onReceive(Context context, Intent intent) {
    TelephonyManager phone = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    MyPhoneStateListener PhoneListener = new MyPhoneStateListener();
    phone.listen(PhoneListener, PhoneStateListener.LISTEN_CALL_STATE);
   }

  private class MyPhoneStateListener extends PhoneStateListener{
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        super.onCallStateChanged(state, incomingNumber);

        switch(state){
        case TelephonyManager.CALL_STATE_RINGING:
         Log.i("CALL","CALL_STATE_RINGING");
        break;
        case TelephonyManager.CALL_STATE_OFFHOOK:
         Log.i("CALL","CALL_STATE_OFFHOOK");
        break;
        case TelephonyManager.CALL_STATE_IDLE:
         Log.i("CALL","CALL_STATE_IDLE");
        break;
        }
      }
   }
 }

打扰我：-

为什么在我调试三星ST7652时，它会在

LogCat

中给出类似的东西，否则它会显示完美的调用状态日志

尝试过

---

。但是，在浏览了关于

PhoneStateListeners

和

android.intent.action.PHONE\u STATE

的多个源代码后，它总是给我

CALL\u IDLE

和传入号码

null
，这对我的解决方案也没有帮助障碍

广播接收机

清单



经允许

这不起作用。只调用空闲和脱离挂钩。并且当呼叫被实际接受时没有侦听器。
