Question

我正在尝试阻止特定号码的来电。首先我尝试所有来电。它运作良好。但是当我通过以下代码尝试特定号码时，呼叫不会被拒绝，电话响了，我尝试使用我的Android手机..

       @Override
     public void onReceive(Context context, Intent intent) {
      Log.v(TAG, "Receving....");
      String t1="01741297163",t2="08801741297163";
      TelephonyManager telephony = (TelephonyManager) 
      context.getSystemService(Context.TELEPHONY_SERVICE);  
      try {
       Class c = Class.forName(telephony.getClass().getName());
       Method m = c.getDeclaredMethod("getITelephony");
       m.setAccessible(true);
       Bundle b=intent.getExtras();
       num=b.getString(telephony.EXTRA_INCOMING_NUMBER);
       if(num.equals(t1)||num.equals(t2)){
       telephonyService = (ITelephony) m.invoke(telephony);
       //telephonyService.silenceRinger();
       telephonyService.endCall();
      } }catch (Exception e) {
       e.printStackTrace();
      }

我不知道来自Telephonymanager的传入号码的格式。

    super.onCallStateChanged(state, incomingNumber);
}

Answer 2

为什么不尝试在日志中打印传入的电话号码，然后将其与您存储的号码进行比较？无论如何，您存储的电话号码t1和t2没有标准/国际代码。正确的电话号码（如果在印度）将是

t1="+911741297163"

Indias男女同校是+91。

Answer 3

您也应该使用该号码添加国家/地区代码。对印度说+91。试试!!
