java.lang.IllegalAccessError: Method 'void android.support.v4.content.ContextCompat.<init>()' is inaccessible

问题

My error is:

Task exception on worker thread: java.lang.IllegalAccessError: Method 'void android.support.v4.content.ContextCompat.()' is inaccessible to class 'com.google.firebase.iid.zzg' (declaration of 'com.google.firebase.iid.zzg' appears in /data/app/android.myland.com.land-1/base.apk): com.google.android.gms.measurement.internal.zzt.zzEd(Unknown Source)

This is pro level:

dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'
    classpath 'com.google.gms:google-services:3.1.0'
}

Because of this : I'm getting this error:

E/Volley: [65295] BasicNetwork.performRequest: Unexpected response code 401 for https://land-db0d7.firebaseio.com/users.json

This is my code of in java file

String url="googlechrome://navigate?url=https://land-db0d7.firebaseio.com/users";

I'm trying to make chatting app using firebase.
