我正在开发应用，我需要它才能进行登录活动。我一直关注这个（developers.google.com/identity/sign-in/android/sign-in）和this，出于某种原因，一切正常，没有崩溃，没有错误消息但没有迹象同样。
但是，每次我启动活动时，我都会在＆＃34; Run＆＃34;标签：
W/System: ClassLoader referenced unknown path: /data/user/0/com.google.android.gms/app_chimera/m/00000008/n/armeabi-v7a
W/System: ClassLoader referenced unknown path: /data/user/0/com.google.android.gms/app_chimera/m/00000008/n/armeabi
和
W/DynamiteModule: Local module descriptor class for com.google.android.gms.crash not found.
和
W/DynamiteModule: Local module descriptor class for com.google.firebase.auth not found.
在我得到的logcat中：
GoogleService failed to initialize, status: 10, Missing an expected resource: 'R.string.google_app_id' for initializing Google services. Possible causes are missing google-services.json or com.google.gms.google-services gradle plugin.
但奇怪的是我的google-services.json目录中有app。
我的项目是：
// 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:2.2.0-alpha7'
classpath 'com.google.gms:google-services:2.0.0-alpha6'
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()
}}
我的模块：app gradle是：
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "(My app ID)"
minSdkVersion 16
targetSdkVersion 24
versionCode 4
versionName "1.3"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:24.1.1'
compile 'com.google.android.gms:play-services:9.4.0'
compile 'com.android.support:design:24.1.1'
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha5'
}
apply plugin: 'com.google.gms.google-services'
现在，这是我的代码（基于谷歌＆＃34;将Google登录集成到您的Android应用程序＆＃34;教程）：

Here is my folder structure (I did it as rakesh kashyap suggested)
有人能帮助我吗？我似乎无法找到问题的根源。

您可以按照以下步骤下载并复制Android应用的google-services.json文件来解决此问题：
答案 1 :(得分：0)
试试这个......
检查您的构建变体（Build - ＆gt; select build variant）。记下变体名称。应该是调试或发布，或者你已经定义了什么
选择项目视图。导航到应用 - ＆gt; src并创建一个与构建变体具有完全相同名称的目录。
将您的JSON文件复制到此目录。
尝试构建 - ＆gt;干净的项目。检查gradle cosole。你应该看到这样的东西（解析json文件：Drive：\ path_to_your_app_dir \ your_app_name \ app \ src \ release_prod \ google-services.json ）
