So, this error showed up when I tried to update gms google services for push notifications.
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.
Currently, I compiled android.gms:play-services with version 8.3.0 which is not allowed at this time cause I have different version level within my build.gradle file. To fix this, you just need to update com.google.gms:google-services version inside both build.gradle files.
build.gradle file in project level :
// Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.3.1' classpath 'com.android.tools.build:gradle:2.2.0' classpath 'com.google.gms:google-services:3.0.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { jcenter() } } task clean(type: Delete) { delete rootProject.buildDir }
inside the build.grade app level file, I added compile ‘com.google.android.gms:play-services:9.0.0’ inside dependencies tag and apply plugin: ‘com.google.gms.google-services’ at the end of lines. So, it looks like this:
apply plugin: 'com.android.application' android { compileSdkVersion 25 buildToolsVersion "25.0.2" defaultConfig { applicationId "com.myLambdaapp.myLambdaapp" minSdkVersion 14 targetSdkVersion 25 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(include: ['*.jar'], dir: 'libs') androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' }) compile 'com.android.support:appcompat-v7:25.3.1' compile 'com.android.support.constraint:constraint-layout:1.0.2' testCompile 'junit:junit:4.12' compile 'com.google.android.gms:play-services:9.0.0' } apply plugin: 'com.google.gms.google-services'
