Question

I am trying to upgrade my google play services dependencies to 8.4.0 by following the example Google gives here, but I am getting the following error (\'com.example.examplea

Answer 1

Simpal an easy In my case it solved by as below

Make sure your pakage name in mainifests file same as your gradle's applicationId.

Answer 2

Please verify build.gradle.

defaultConfig {
        applicationId "<packagename>"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }

Verify the package name.It can also cause error.

Answer 3

I found success using this configuration:

classpath 'com.android.tools.build:gradle:1.5.0'
classpath 'com.google.gms:google-services:2.0.0-alpha3'
//or use
//classpath 'com.android.tools.build:gradle:2.0.0-alpha6'

and

distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip

using 8.40 Google Play services. Alpha5 & Alpha6 gave the same 2.8 error you had, regardless of the distributionUrl being 2.10

Answer 4

Add this in project gradle file

classpath 'com.google.gms:google-services:3.0.0'

Answer 5

Solved the problem of getting an exception

java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process Make sure to call FirebaseApp.initializeApp(Context) first.

in FirebaseInstanceId.getInstance().getToken()

Check that package_name exactly matches applicationId 1) build.gradle

defaultConfig {
        applicationId "build.gradle.exactly.matches.json"
...
}

---

should exactly match 2) google-services.json

{
      "client_info": {
        "mobilesdk_app_id": "xxxxxxxxxxxxxxxxxxxxxxxxxx",
        "android_client_info": {
          "package_name": "build.gradle.exactly.matches.json"
        ....

Answer 6

This exact same error happened to me only when I tried to build my debug build type. The way I solved it was to change my google-services.json for my debug build type. My original field had a field called client_id and the value was android:com.example.exampleapp, and I just deleted the android: prefix and leave as com.example.exampleapp and after that my gradle build was successful.

Hope it helps!

EDIT

I've just added back the android: prefix in my google-services.json and it continued to work correctly. Not sure what happened exactly but I was able to solve my problem with the solution mentioned above.
