Firebase admin sdk 未与 gradle 同步

Question

我已将一些库合并到我的 android 应用程序中。我已将它与 Firebase 云服务器连接起来。现在，我想为用户身份验证创建令牌。 Firebase 要求将 Firebase Admin Sdk 添加到 gradle 文件。但是，它在构建 gradle 时显示错误。我添加的sdk是compile 'com.google.firebase:firebase-admin:5.3.1'

错误如下：

Error:Conflict with dependency 'com.google.code.findbugs:jsr305' in project ':app'. Resolved versions for app (3.0.0) and test app (2.0.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details.

我的原代码是：

apply plugin: com.android.application

android {

compileSdkVersion 25

buildToolsVersion "25.0.2"

defaultConfig {

    applicationId "com.example.delluser.oshoguide"

    minSdkVersion 17

    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'
    }
}

packagingOptions
        {

            exclude 'META-INF/notice'
            exclude 'META-INF/notice.txt'
            exclude 'META-INF/license'
            exclude 'META-INF/license.txt'
        }

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-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.google.firebase:firebase-crash:11.0.1'
compile 'com.google.firebase:firebase-auth:11.0.1'
compile 'com.google.firebase:firebase-database:11.0.1'
compile 'com.google.firebase:firebase-messaging:11.0.1'
compile 'com.google.firebase:firebase-storage:11.0.1'
compile 'com.firebase:firebase-client-android:2.3.1'
compile 'com.firebaseui:firebase-ui:0.6.2'
compile 'com.android.support:design:25.3.1'
compile 'com.google.firebase:firebase-admin:5.3.1'

testCompile 'junit:junit:4.12'
}


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

firebase-admin 不属于 Android 应用。它用于服务器端应用程序。如果您尝试将它添加到 Android 应用程序，它肯定会与其他 Firebase 库发生冲突。

如果您想创建自定义身份验证令牌，则必须在服务器上进行。请注意 Firebase Admin SDK 文档的标题：Add the Firebase Admin SDK to Your Server.
