权限拒绝:需要android.Permission.READ_PHONE_STATE

我试图在我的android应用程序中检测电话呼叫,但在接到呼叫时收到以下消息:

08-23 15:16:04.685  Vodafone VFD 600    Warning 850 BroadcastQueue  Permission Denial: receiving Intent { act=android.intent.action.PHONE_STATE flg=0x10 (has extras) } to com....LogCalls requires android.permission.READ_PHONE_STATE due to sender android (uid 1000)
08-23 15:16:04.549  Vodafone VFD 600    Warning 850 BroadcastQueue  Permission Denial: receiving Intent { act=android.intent.action.PHONE_STATE flg=0x10 (has extras) } to com....LogCalls requires android.permission.READ_PRIVILEGED_PHONE_STATE due to sender android (uid 1000)

我的AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="com...." android:installLocation="preferExternal">
    <uses-sdk android:minSdkVersion="15" android:targetSdkVersion="27" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
  <uses-permission android:name="android.permission.READ_PHONE_STATE" />
  <uses-permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE" />
    <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
    <application android:label="myapp" android:icon="@drawable/logo">
    </application>
</manifest>

我的广播接收器:

[BroadcastReceiver]
[IntentFilter(new[] {TelephonyManager.ActionPhoneStateChanged,Intent.ActionNewOutgoingCall })]
public class LogCalls : BroadcastReceiver
{
    public override void OnReceive(Context context, Intent intent)
    {
        if (intent.Action == TelephonyManager.ActionPhoneStateChanged)
        {
            Console.WriteLine("state changed");
        }
    }
}

我错过了什么?
