Google Play Services GCM 9.2.0 asks to "update" back to 9.0.0

So this morning I started updating to the latest version of my project libraries.

I'm trying to update GCM to the latest version 9.2.0, but I get this error:

Error:Execution failed for task ':app:processDebugGoogleServices'. Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 9.0.0.

This is how I have my code:

dependencies {
    classpath 'com.android.tools.build:gradle:2.1.2'
    classpath 'com.google.gms:google-services:3.0.0'
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}

And then:

dependencies {
    ...

    compile "com.google.android.gms:play-services-gcm:9.2.0"

    ...
}

Anyone having the same issue/fixed the same issue?

Thanks.

EDIT

Apparently you have to apply your GSM plugin at the bottom of your app/build.gradle file. Else, version 9.2.0 will cause conflict in your project.

For reference, this is how my app/build.gradle file looks like now:

apply plugin: "com.android.application"
apply plugin: "com.neenbedankt.android-apt"

android {
    ...
}

dependencies {
    ...

    // Google Cloud Messaging
    compile "com.google.android.gms:play-services-gcm:9.2.0"

    ...
}

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

Solution 1:

Do you have the line

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

line at the bottom of your app's build.gradle file?

I saw some errors when it was on the top and as it's written here, it should be at the bottom.

Solution 2:

Just put this line at the bottom of your app-module's (not project root's) gradle file.

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

Then rebuild your project.

Solution 3:

I had the same problem, today 2016 - october - 06 I solved with this:

I changed all dependencies that began with 9.?.? to 9.6.1 I compiled with sdk version 24 and target version 17.

There is another packages in my solution because I used more things then only authentication.

After changed your build.gradle (Module:app) with the code below do it:

1. Put your package NAME in the line with the words applicationId "com.YOUR_PACKAGE_HERE"

2. Synchronize your project (Ctrl+alt+v) and Build Again.

This is the code of the file buid.gradle (Module:app) that worked for me:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.3"
    defaultConfig {
        applicationId "com.YOUR_PACKAGE_HERE"
        minSdkVersion 24
        targetSdkVersion 17
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile 'com.google.firebase:firebase-core:9.6.1'
    compile 'com.google.firebase:firebase-database:9.6.1'

    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:design:24.2.1'

    compile 'com.google.firebase:firebase-crash:9.6.1'
    testCompile 'junit:junit:4.12'

    compile 'com.google.firebase:firebase-messaging:9.6.1'

    compile 'com.google.firebase:firebase-ads:9.6.1'


    compile 'com.google.firebase:firebase-auth:9.6.1'


    compile 'com.google.android.gms:play-services:9.6.1'

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