android - PhoneStateListener 返回 null 作为传入号码

Question

我正在开发电话和短信拦截应用程序，我遇到了无法从 phonestatelistener 获取来电号码的问题。我的代码如下所示:

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());

//如果号码与我们的阻止号码匹配，则拒绝调用

                    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;
    }
}

所以我的程序没有像我期望的那样工作，因为它总是返回 null 作为传入数字。

我的 list 看起来像这样:

<?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="oleksandr.ivanets.dontwakemeapp">
<uses-permission android:name="android.permission.RECEIVE_SMS" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>



    <receiver
        android:name=".PhoneStateReceiver"
        android:enabled="true"
        android:permission="android.permission.BROADCAST_SMS">
        <intent-filter android:priority="999999999">
            <action android:name="android.intent.action.PHONE_STATE" />
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
    </receiver>




</application>

   </manifest>

Answer 1

尝试添加此权限，在我的例子中这有效。

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