build.gradle(app):

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

}

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

build.grade(Project):

repositories {
jcenter()
}
依赖关系{
classpath'com .android.tools.build:gradle:2.2.0'
classpath'com.google.gms:google-services:3.0.0'


//注意:不要在这里放置应用程序依赖关系;他们属于
//在个人模块build.gradle文件
}
}

解决方案

更改

$ b $ $

  b $ b 


 编译'com.google.android.gms:play-services:9.8.0'


结论:

 依赖项{
编译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'c​​om.android.support:appcompat-v7:24.2.1'
compile'c​​om.android .support:design:24.2.1'
compile'c​​om.android.support:support-v4:24.2.1'
compile'c​​om.google.android.gms:play-services:9.8.0 '
compile'c​​om.google.firebase:firebase-core:9.8.0'

testCompile'junit:junit:4.12'
}


build.gradle (app):

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.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:design:24.2.1'
    compile 'com.android.support:support-v4:24.2.1'
    compile 'com.google.android.gms:play-services:7.5.0'
    compile 'com.google.firebase:firebase-core:9.8.0'

    testCompile 'junit:junit:4.12'
}

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

build.grade (Project):

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        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
    }
}

Google services and Google repositories are all up to date as per the SDK.

I am getting the following error:

Error:(42, 1) A problem occurred evaluating project ':app'.
> Failed to apply plugin [id 'com.google.gms.google-services']
   > Version: 7.5.0 is lower than the minimum version (9.0.0) required for google-services plugin.

I am trying to connect to Firebase from my app and I have the google-services.json file inside the app folder.

How can I resolve the issue to connect to Firebase.

解决方案

change

compile 'com.google.android.gms:play-services:7.5.0'

to

compile 'com.google.android.gms:play-services:9.8.0'

In conclusion:

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.android.support:appcompat-v7:24.2.1'
compile 'com.android.support:design:24.2.1'
compile 'com.android.support:support-v4:24.2.1'
compile 'com.google.android.gms:play-services:9.8.0'
compile 'com.google.firebase:firebase-core:9.8.0'
