呼叫接收器的 PhoneStateListener 在真实设备中不起作用

Question

我创建了BroadCastReceiver，它监听IncomingCall 和Outgoing Calls。尝试在BroadCastReceiver 中添加PhoneStateListener 和TelephonyManager，这在模拟器和某些设备上完美运行。

它不适用于Samsung ST 7652。总是返回CALL_STATE_IDLE 和来电号码null。为什么会这样？

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;
        }
      }
   }
 }

打扰我了：-

  E/MSimTelephonyManager(621): MSimTelephonyManager sRegistryMsim != null

为什么当我为 Samsung ST 7652 调试时它会在 LogCat 中给出类似的内容，否则它会显示完美的呼叫状态日志？

试过

PhoneStateListener not working with some devices。但它也没有帮助我解决这个问题总是给我CALL_STATE_IDLE和传入号码null。

在浏览了有关 PhoneStateListeners 和 android.intent.action.PHONE_STATE 的多个来源后，我找到了我正在寻找的东西，并且无论模型特定的障碍如何，它都能像魅力一样工作。

BroadCastReceiver

 public class PhoneStateReceiver extends BroadcastReceiver {
    public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    String str = intent.getAction();
    if ("android.intent.action.PHONE_STATE".equals(str))
        inComing(context, intent);

    if ("android.intent.action.NEW_OUTGOING_CALL".equals(str))
        outGoing(context, intent);
  }

 private void inComing(Context context, Intent intent){
    String callState = intent.getStringExtra("state");
    if ("RINGING".equals(callState)){
        Log.i(TAG, "RINGING SENDS BUSY");
    }else if ("OFFHOOK".equals(callState)){
        Log.i(TAG, "OFFHOOK SENDS BUSY");
    }else if("IDLE".equals(callState)){
        Log.i(TAG, "IDLE SENDS AVAILABLE"); 
    }
  }

 private void trueCallerOutgoing(Context context, Intent intent)
  {
    String callState = intent.getStringExtra("state");
    if ("RINGING".equals(callState)){
            Log.i(TAG, "RINGING SENDS BUSY");
    }else if ("OFFHOOK".equals(callState)){
            Log.i(TAG, "OFFHOOK SENDS BUSY");
    }else if("IDLE".equals(callState)){
            Log.i(TAG, "IDLE SENDS AVAILABLE"); 
    }
  }
}

清单

 <receiver android:name="PhoneStateReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>
