Unable to get provider com.google.android.gms.measurement.AppMeasurementContentProvider

Question

I tried to Set up GCM in my project as given in Set up a GCM Client App on Android and to Set Up Google Play Services added dependency

  compile "com.google.android.gms:play-services-gcm:8.4.0"

to the dependency section of my application's build.gradle file.

And In the root gradle file add classpath as given in sample project(Sample cloned from $ git clone https://github.com/googlesamples/google-services.git) as

dependencies {
    classpath 'com.android.tools.build:gradle:2.0.0-beta6'
    classpath 'com.google.gms:google-services:2.0.0-beta6'
}

It's building fine, but it crashes on launch with the following stack trace :

java.lang.RuntimeException: Unable to get provider com.google.android.gms.measurement.AppMeasurementContentProvider: java.lang.NullPointerException: null reference at android.app.ActivityThread.installProvider(ActivityThread.java:5156) at android.app.ActivityThread.installContentProviders(ActivityThread.java:4748) at android.app.ActivityThread.handleBindApplication(ActivityThread.java:4688) at android.app.ActivityThread.-wrap1(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1405) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:5417) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) Caused by: java.lang.NullPointerException: null reference at com.google.android.gms.common.internal.zzx.zzy(Unknown Source) at com.google.android.gms.measurement.internal.zzt.zzaU(Unknown Source) at com.google.android.gms.measurement.AppMeasurementContentProvider.onCreate(Unknown Source) at android.content.ContentProvider.attachInfo(ContentProvider.java:1748) at android.content.ContentProvider.attachInfo(ContentProvider.java:1723) at android.app.ActivityThread.installProvider(ActivityThread.java:5153) at android.app.ActivityThread.installContentProviders(ActivityThread.java:4748)  at android.app.ActivityThread.handleBindApplication(ActivityThread.java:4688)  at android.app.ActivityThread.-wrap1(ActivityThread.java)  at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1405)  at android.os.Handler.dispatchMessage(Handler.java:102)  at android.os.Looper.loop(Looper.java:148)  at android.app.ActivityThread.main(ActivityThread.java:5417)  at java.lang.reflect.Method.invoke(Native Method)  at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726)  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616)

Also tried related stack questions:

1. Updating Play services from 8.1 to 8.3 with Proguard enabled
2. Error on some devices - couldn't find class 'com.google.android.gms.measurement.internal.zzz'

As answered in 1st link tried classpath

classpath 'com.google.gms:google-services:1.5.0'

and as answered in 2nd link,tried Multidex also with no success.

Also tried for Application Measurement adding

<?xml version="1.0" encoding="utf-8"?>
<resources>
   <integer name="google_app_measurement_enable">0</integer>
</resources>

as suggested in Play Services Release notes.

Note : sample code running.

Update :

Interesting thing is that same error even if I add only dependency

  compile "com.google.android.gms:play-services-gcm:8.4.0"

in my app gradle file(Note : Only one line added in Existing project).And there is no error after adding

compile "com.google.android.gms:play-services-gcm:8.1.0"

i.e. the token works on 8.1.0.Interesting,isn't?

Answer 1

Did you remember to add the plugin to the end of your app-level build.gradle file? ...

apply plugin: 'com.google.gms.google-services'

You specifically need to add it to the very end of the file.

Take a look here for reference: https://github.com/googlesamples/google-services/blob/master/android/gcm/app/build.gradle

There is also a bug report opened on this issue: Issue 193112

Answer 2

From Android studio menu go to:

• Build → Clean Project

• Build → Rebuild Project

• Run the app. No more crash.

Note: I am using the latest version of play-services:

compile 'com.google.android.gms:play-services:8.4.0'

Try to change your classpath dependency, instead of 'classpath 'com.google.gms:google-services:2.0.0-beta6'', use classpath ' classpath 'com.google.gms:google-services:1.5.0''.

Here is a related stack overflow ticket, you may check the solution offered by community:. It was stated that they already filed bug ticket and the said fix has been implemented in release 1.5.0 of the foot service plugin.
