什么是一个App Engine后端与谷歌云消息？

必需依赖的gradle

目前，当你添加一个模块，这样到Android Studio项目它增加了这种依赖性：

编译com.google.android.gms：发挥服务：8.4.0

但是，当您运行项目，你得到这个错误：

  

错误：执行失败的任务
  '：应用程序：transformClassesWithDexForDebug。

  
  

    

com.android.build.api.transform.TransformException：com.android.ide.common.process.ProcessException：
    org.gradle.process.internal.ExecException：进程命令
    /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bin/java''
    非零退出值完成2

  

使用这个有人建议：

  defaultConfig {
        multiDexEnabled真
}
 

但实际上并没有为我工作。

这样看来，我必须只指定GAE + GCM所需的库。到目前为止，我有：

 编译com.google.android.gms：发挥服务-auth的：8.4.0
编译com.google.android.gms：播放服务-GCM：8.4.0
编译com.google.android.gms：播放服务基地：8.4.0
 

完整列表这里。但是，这并不能正常工作。我得到这个错误：

  

E / GMPM：GoogleService初始化失败，状态：10，缺少的
  预计资源：R.string.google_app_id初始化谷歌
  服务。可能的原因是缺少谷歌，services.json或
  com.google.gms.google服务插件的gradle

所以，我很茫然。

有没有解决这个问题，一些其他的方式？什么是奇怪的是我的老GAE + GCM项目做工精细导入整个谷歌播放服务。在我的新项目导入这些旧版本的谷歌播放服务不但是工作。所以，我不知道是怎么回事。

编辑：一些详细信息：

我做了一些测试。

1）开始新的Andr​​oid Studio项目，增加了新的谷歌云模块'App Engine的Java的端点模块。自动生成的build.grade（模块：APP）是这样的：

  {相关性
    编译文件树（导演：'库'，包括：['的* .jar']）
    testCompile'的JUnit：JUnit的：4.12
    编译com.android.support:appcompat-v7:23.1.1
    编译com.android.support:design:23.1.1
    编制项目（路径：'：后端，配置：Android的终端）
}
 

结果？编译和运行完美 - ！没有问题

2）开始新的Andr​​oid Studio项目，增加了新的谷歌云模块'App Engine的后端与谷歌云通讯。自动生成build.grade（模块：APP）是这样的：

  {相关性
    编译文件树（导演：'库'，包括：['的* .jar']）
    testCompile'的JUnit：JUnit的：4.12
    编译com.android.support:appcompat-v7:23.1.1
    编译com.android.support:design:23.1.1
    编译com.google.android.gms：播放服务：8.4.0
    编制项目（路径：'：后端，配置：Android的终端）
}
 

结果？同样糟糕的错误，我已经越来越！

所以它看起来像线编译com.google.android.gms：发挥服务：8.4.0''的问题。我用

取代了它

编译com.google.android.gms：发挥服务-GCM：8.4.0''

因为理论上这是所有我需要谷歌的云消息。当我运行它，我得到这样的：

  

12-30 14：14：16.482 10573-10573 / com.myapp.myapp
  E / GMPM：GoogleService初始化失败，状态：10，缺少的
  预计资源：R.string.google_app_id初始化谷歌
  服务。可能的原因是缺少谷歌，services.json或
  com.google.gms.google服务gradle这个插件。 12-30 14：14：16.482
  10573-10573 / com.myapp.myapp E / GMPM：调度不
  组。不记录错误/警告。 12-30 14：14：16.502
  10573-10623 / com.myapp.myapp E / GMPM：是上传
  不可能。应用测量禁用

所以看起来我缺少这个谷歌，services.json文件什么的。我不明白发生了什么事了Android工作室，因为几个月前，我做了一个GCM启用应用程序相同的方式，一个编译没有问题。该应用程序的gradle.build文件看起来是这样的：

  {相关性
    编译文件树（包括：['的* .jar']，DIR：库）
    编制项目（路径：'：GCM后端，配置：Android的终端）
    编译com.android.support:appcompat-v7:22.2.0
    编译com.ganyo：GCM服务器：1.0.2
    编译com.google.android.gms：播放服务：7.5.0
    编译com.android.support:support-v4:22.2.0
}
 

因此​​，它看起来像Android的工作室停止添加编译com.ganyo：GCM服务器：1.0.2''的依赖。

于是我就一个项目

 编译com.ganyo：GCM服务器：1.0.2
编译com.google.android.gms：播放服务：8.4.0
 

结果？同一个执行失败的错误。

好了，所以让我们尝试在我的新项目老戏服务库：

 编译com.ganyo：GCM服务器：1.0.2
编译com.google.android.gms：播放服务：7.5.0
 

结果？同一个执行失败的错误。

我只是不明白为什么这是不工作的开箱像以前那样...

解决方案

preliminary实验表明，该工程至今。

我把在看谷歌GCM示例项目在这里： HTTPS ：//github.com/googlesamples/google-services/tree/master/android/gcm

和编辑的gradle我的文件。这里是他们的样子现在：

APP：

 应用插件：'com.android.application安卓{
    compileSdkVersion 23
    buildToolsVersion23.0.2    defaultConfig {
        的applicationIDcom.me.myapp
        13的minSdkVersion
        targetSdkVersion 23
        版本code 1
        的versionName1.0
    }
    buildTypes {
        发布 {
            minifyEnabled假
            proguardFiles getDefaultProguardFile（'proguard的-android.txt'），'proguard-rules.pro
        }
    }
}依赖{
    编译文件树（导演：'库'，包括：['的* .jar']）
    编译com.google.android.gms：播放服务-GCM：8.4.0
    testCompile'的JUnit：JUnit的：4.12
    编制项目（路径：'：后端，配置：Android的终端）
    编译com.android.support:appcompat-v7:23.1.1
    编译com.android.support:design:23.1.1
}应用插件：'com.google.gms.google的服务。
 

项目：

  //顶级构建文件，您可以添加常用的配置选项，所有分项目/模块。buildscript {
    库{
        jcenter（）
    }
    依赖{
        类路径'com.android.tools.build:gradle:1.5.0
        类路径'com.google.gms：谷歌服务：2.0.0-素α3
        //注意：不要在这里把你的应用程序依赖关系;他们属于
        //在单个模块的build.gradle文件
    }
}allprojects {
    库{
        jcenter（）
    }
}任务清除（类型：删除）{
    删除rootProject.buildDir
}
 

和还我跟着这指南（见步骤2）生成我投进应用程序/目录谷歌-services.json文件。

现在应用程序编译和工作（至少到目前为止）。

我真的生气了，这并不开箱与自动生成的文件的gradle和我必须追捕他们在一些示例应用程序。它没有用是这样仅仅在几个月前。它一旦担任您添加的GCM模块。

如果任何人有任何提示/为将来的项目建议，请让我知道。 = D

What are the necessary gradle dependencies for an App Engine Backend with Google Cloud Messaging?

Currently, when you add a module like that to your Android Studio project it adds this dependency:

'compile 'com.google.android.gms:play-services:8.4.0'

However, when you run the project you get this error:

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.

com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bin/java'' finished with non-zero exit value 2

Someone suggested using this:

defaultConfig {
        multiDexEnabled true
}

But that actually didn't work for me.

So it appears that I have to specify only the required libraries for GAE + GCM. So far I have:

compile 'com.google.android.gms:play-services-auth:8.4.0'
compile 'com.google.android.gms:play-services-gcm:8.4.0'
compile 'com.google.android.gms:play-services-base:8.4.0'

full list here. But that didn't work. I got this error:

E/GMPM: 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.

So I am at a loss.

Is there some other way around this issue? What is weird is my old GAE + GCM projects work fine importing the whole google play services. Importing those older versions of google play services in my new project does not work however. So I am not sure what is going on.

EDIT: Some more information:

I did some tests.

1) Started new Android Studio project, added new google cloud module 'App Engine Java Endpoints Module'. The auto-generated build.grade (Module: app) looks like this:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile project(path: ':backend', configuration: 'android-endpoints')
}

Result? Compiles and runs perfectly - no problems!

2) Started new Android Studio project, added new google cloud module 'App Engine Backend with Google Cloud Messaging'. the auto-generated build.grade (Module: app) looks like this:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.google.android.gms:play-services:8.4.0'
    compile project(path: ':backend', configuration: 'android-endpoints')
}

Result? Same crappy error I have been getting!

So it looks like the line 'compile 'com.google.android.gms:play-services:8.4.0'' is the problem. I replaced it with

'compile 'com.google.android.gms:play-services-gcm:8.4.0''

since in theory that is all I need for google cloud messaging. When I run it I get this:

12-30 14:14:16.482 10573-10573/com.myapp.myapp E/GMPM: 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. 12-30 14:14:16.482 10573-10573/com.myapp.myapp E/GMPM: Scheduler not set. Not logging error/warn. 12-30 14:14:16.502 10573-10623/com.myapp.myapp E/GMPM: Uploading is not possible. App measurement disabled

So it looks like I am missing this google-services.json file or something. I don't get what happened with Android Studio because several months ago I made a GCM enabled app the same way and that one compiles no problem. The gradle.build file of that app looks like this:

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile project(path: ':gcm-backend', configuration: 'android-endpoints')
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.ganyo:gcm-server:1.0.2'
    compile 'com.google.android.gms:play-services:7.5.0'
    compile 'com.android.support:support-v4:22.2.0'
}

So it looks like Android Studio stopped adding the 'compile 'com.ganyo:gcm-server:1.0.2'' dependency.

So I ran a project with

'compile 'com.ganyo:gcm-server:1.0.2'
'compile 'com.google.android.gms:play-services:8.4.0'

Result? Same Execution failed error.

Ok so let's try the old play-services library in my new project:

'compile 'com.ganyo:gcm-server:1.0.2'
'compile 'com.google.android.gms:play-services:7.5.0'

Result? Same Execution failed error.

I just don't get why this isn't working out of the box like it used to...

解决方案

Preliminary tests show that this works so far.

I took at a look at the google GCM sample project here: https://github.com/googlesamples/google-services/tree/master/android/gcm

And edited my gradle files. Here is what they look like now:

APP:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.me.myapp"
        minSdkVersion 13
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services-gcm:8.4.0'
    testCompile 'junit:junit:4.12'
    compile project(path: ':backend', configuration: 'android-endpoints')
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
}

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

PROJECT:

// 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:1.5.0'
        classpath 'com.google.gms:google-services:2.0.0-alpha3'
        // 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
}

And also I followed this guide (see step 2) to generate a google-services.json file which I dropped into the app/ directory.

Now the app compiles and works (so far at least).

I'm really angry this doesn't work out of the box with the auto generated gradle files and that I have to hunt them down in some sample app. It didn't used to be this way just a few months ago. It worked as soon as you added the GCM module.

If anyone else has any tips/suggestions for future projects please let me know. =D
