java.lang.ClassNotFoundException: Didn't find class “com.google.android.gms.measurement.AppMeasurement” on path: DexPathList

Question

My app was running well but it is crashing now. I started getting warnings even though I am not integrating with firebase. Now I think that I can not solve this problem. I tried every possible solution available on stackoverflow. Also, I am using viewpager in my code if that helps.

LogCat

 W/Ads: Invoke Firebase method getInstance error.

Answer 1

I think this issue is similar with How to enable multidexing with the new Android Multidex support library

1. Add implementation "com.android.support:multidex:1.0.1" in your build.gradle's dependencies ( implementation can be replaced with compile );

2. Add a custom application extends from Application. Add code as below:

    override fun attachBaseContext(base: Context?) { super.attachBaseContext(base) MultiDex.install(this) } 

3. Add your custom application in AnroidManifest.xml as android:name=".CustomApplication"

Answer 2

您应该使用编译“ com.google.firebase：firebase-ads：11.2.0”，而不是编译“ com.google.android.gms：play-services-ads：11.2.0”
