Question

我正在尝试将firebase集成到我的Android应用程序中。我从firebase控制台下载了google-services.json文件，在classpath 'com.google.gms:google-services:3.0.0'中添加了project/build.gradle。我还在apply plugin: 'com.google.gms.google-services'添加了app/build.gradle。我使用的是谷歌播放服务版本9.2.1。但是，当我使用gradle同步项目文件时，出现以下错误：

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.

如果我将com.google.android.gms的版本更改为9.0.0，则会成功同步，但是当我运行我的应用时，我会收到以下错误：

以下是我的依赖项：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'


    compile 'com.android.support:appcompat-v7:24.1.1'
    compile 'com.android.support:design:24.1.1'
    compile 'com.android.support:support-v4:24.1.1'
    compile 'com.android.support:multidex:1.0.1'
    compile 'com.google.android.gms:play-services-location:9.0.0'
    compile 'com.google.android.gms:play-services-maps:9.0.0'
    compile 'com.android.support:recyclerview-v7:24.1.1'
    compile 'com.android.support:preference-v7:24.1.1'
    compile 'com.android.support:preference-v14:24.1.1'
    compile 'com.firebase:firebase-client-android:2.5.2'
    compile 'com.google.firebase:firebase-auth:9.0.0'
    compile 'com.google.android.gms:play-services-auth:9.0.0'

    compile 'com.facebook.android:facebook-android-sdk:[4,5)'
    compile 'com.mikhaellopez:circularimageview:3.0.2'

任何人都可以指导我如何使用firebase以及google play服务版本9.2.1 ????

Answer 1

您是否尝试使用

'com.google.firebase:firebase-auth:9.2.1'

带

'com.google.android.gms:play-services:9.2.1' ?

9.2.1版本的firebase可以在7月14日使用。

Answer 2

根据Google Play services 9.0.1 release notes：

使用ContextCompat.getNoBackupFilesDir（）修复了类更改编译错误。

如果您要使用Android支持库版本24.0.0或更高版本，请更新所有Google Play服务和Firebase依赖关系以使用9.0.1或更高版本。
