PhoneStateListener返回null作为传入号码

Question

I am developing calls and sms blocking app, I have encountered the problem where I can't get incoming number from phonestatelistener. My code looks like this:

public void onCallStateChanged(int state, String incomingNumber) {

    switch (state) {
        case TelephonyManager.CALL_STATE_IDLE:



            break;
        case TelephonyManager.CALL_STATE_OFFHOOK:

            break;
        case TelephonyManager.CALL_STATE_RINGING:





            System.out.println("incoming number PhoneStateListener:" + incomingNumber);

                if (sBlockCall>0){
                    MuteAudio(getContext());

//reject call if number is matched to our blocking number

                    boolean callShouldBeBlocked = true;
                    for(int i = 0; i<sWhiteList.size(); i++){
                        if(sIncomingNumber.contains(sWhiteList.get(i).mNumber)){
                            UnMuteAudio(getContext());
                            System.out.println("CONTACT IS IN WHITE LIST");

                            callShouldBeBlocked = false;

                            break;
                        }
                    }
                    if(callShouldBeBlocked){
                        System.out.println("BLOCK CALL");
                        disconnectPhoneItelephony();

                    }


                } else {
                    UnMuteAudio(getContext());
                }

                //IT WORKS






            break;
    }
}

So my programm works not as I expect it to work, cause it always returns null as incoming number.

My manifest looks like this:

<?xml version="1.0" encoding="utf-8"?>

            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
    </receiver>




</application>

   </manifest>

尝试添加此权限，在我看来，这是可行的。

<uses-permission android:name="android.permission.READ_CALL_LOG"/>
