[android] Gradle Error:Execution failed for task ':app:processDebugGoogleServices'

I am following this link to integrate Google sign-in in my android app.https://developers.google.com/identity/sign-in/android/start-integrating As given in last step on the above given page we have to include dependency

 compile 'com.google.android.gms:play-services-auth:8.3.0' 

in app-level build.gradle file but doing so and building project an error comes saying

Error:Execution failed for task ':app:processDebugGoogleServices'.
> Please fix the version conflict.

build.gradle(Module:app)

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

}

In the build.gradle file the compile dependency line compile 'com.google.android.gms:play-services-auth:8.3.0' shows error

All com.google.android.gms libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 8.3.0, 8.1.0. Examples include com.google.android.gms:play-services-base:8.3.0 and com.google.android.gms:play-services-measurement:8.1.0 There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion.)

Here are the messages of gradle build.

I am not able to see any way out for this version conflict. Any help is appreciated.

I was finding the same error complaining about mixing google play services version when switching from 8.3 to 8.4. Bizarrely I saw reference to the app-measurement lib which I wasn't using.

I thought maybe one of my app's dependencies was referencing the older version so I ran ./gradlew app:dependencies to find the offending library (non were).

But at the top of task output I found a error message saying that the google plugin could not be found and defaulting to google play services 8.3. I used the sample project @TheYann linked to compare. My setup was identical except I applied the apply plugin: 'com.google.gms.google-services' at the top my app's build.gradle file. I moved to bottom of the file and that fixed the gradle compile error.

Had the same problem i added compile 'com.google.android.gms:play-services-measurement:8.4.0' and deleted apply plugin: 'com.google.gms.google-services' I was using classpath 'com.google.gms:google-services:2.0.0-alpha6' in the build project.

I just had to delete and reinstall my google-services.json and then restart Android Studio.

NEVER DELETE apply plugin: 'com.google.gms.google-services' from the gradle. Sometimes you are using com.google.gms:google-services:3.1.0 , without apply plugin: 'com.google.gms.google-services' your gradle build successfully. BUT IT IS COMPLETELY WRONG !!!! This error comes due to google-service.json file is not at the correct location. Go to your PROJECT TAB at left side above. If you display it as ANDROID make it PROJECT then check your google-service.json file is at this location. EXPAND app then see google-service.json file below the build.gradle. IF NOT PLACE IT THERE BY RIGHT CLICK ON THE app .

Had the same problem with malformed error Deleted the line apply plugin: 'com.google.gms.google-services' And the build got successful

Ensure that you have done these two things under defaultConfig in Android/app/build.gradle after wiring up Firebase for your Flutter app.

1) Whatever package name you entered while creating your Firebase android project, exactly the same should be updated as your applicationId under defaultConfig.

2) Add the line multiDexEnabled true under defaultConfig.

So defaultConfig{} should now look something like this

defaultConfig {
    applicationId "com.companyName.appName"
    minSdkVersion 16
    targetSdkVersion 27
    multiDexEnabled true
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

had the same issue as described by @scottyab.

all references were 8.4.0 but it failed due to a reference to app-measurement 8.3.0 that i did not reference anywhere (but one of the dependencies?). you can see the problem if you hover over the bad(red) dependency in Android Studio. explicitly adding

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

to app.gradle solved the issue.

I fixed it without deleting apply plugin: 'com.google.gms.google-services' I had the error Execution failed for task ':app:processDebugGoogleServices' because I was using two different versions of google services in my dependencies :

implementation "com.google.android.gms:play-services-maps:11.8.0"
implementation "com.google.android.gms:play-services-nearby:16.0.0"

I changed it to :

implementation "com.google.android.gms:play-services-maps:11.8.0"
implementation "com.google.android.gms:play-services-nearby:11.8.0"

Then it worked

If you´re building a new app, put the jsonfile in the right place and make sure it's the jsonfile for that app. Before I realized this, when I clicked the jsonfile, I didn't get the information that wanted.

Go to firebase configurations, download the correct version of google-services.json, and replace the version that didn't work for you. When using the wrong version, you might see the wrong Projectid, storagebucket etc.

In my case when i was using firebase services the google.json file was mismatched check once that also

I had the same issue and resolved it by adding the following line in the dependencies of the project-level build.gradle:

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

For a full working example, check out the following project on github.

Hope this helps :)

same issue i have.

i tired all possible solutions that i found. but non were worked.

always got this error

Cannot add task ':processDebugGoogleServices' as a task with that name already exists

Now, i solved it.

1) first i checked my config.xml

2) and removed unnecessary plugin. (I used firebase fcm plugin for pushnotification, but there was two unnecessary plugin phonegap-plugin-push and cordova-plugin-customurlscheme. I removed both these plugins)

3) then removed platform.

4) then add platform

5) then build it.

6) now it build successfully.

Important note: You should only apply plugin at bottom of build.gradle (App level)

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

I mistakenly apply this plugin at top of the build.gradle. So I get error.

One more tips : You no need to remove even you use the 3.1.0 or above. Because google not officially announced

   classpath 'com.google.gms:google-services:3.1.0' 

I had a similar issue/error.. fixed it by moving apply plugin: 'com.google.gms.google-services'
to the end of app level gradle file.

And updated the version of gms:play-services and gms:play-services auth

When you create an android application in firebase console you should set your application package in future it will be recorded to google-services.json. So this error can happen when you try to add google services in the application which has a different package (Current application package will not match to which was recorded to google-services.json).

Also please check your package name in Manifest and package name in google services json file. If both have package name differ from one another u will have this issue.

check gradle.properties and add android.useAndroidX=true or you can also add android.enableJetifier=true or you can comment it by #

worked for me

None of the answers here helped. I needed to have "apply plugin: 'com.google.gms.google-services'" in my gradle. What helped was updating Android Studio to the latest version. I was then able to add the plugin and connect to Firebase Messaging Service.

In my case i have multiple product flavors. It used to work earlier. It stopped working after updating project gradle version to 4.0.1 and 'google-services:4.3.4'.

I got error like 'Task :app:processDebugGoogleServices FAILED' when i run the project.

I replaced 'google-services.json' in app module with 'my-product-flavor/google-services.json'. It is working fine now.

I've solved this problem by deleting the google-services.json file and downloading it again from Firebase console.

I also faced the same issue. But I forgot to add google-services.json in my project. You can get this file from Google.

This error comes up when there is change in your config.xml file resulting in mismatching of the data present in google-services.json file. I got it fixed this just by updating changes to my google-services.json file and building the app again ...it worked well.

if you got an error

Execution failed for task ‘:app:fabricGenerateResourcesDebug’. Crashlytics Developer Tools error.

remove also this line:

apply plugin: 'io.fabric'
