Google Cloud Messaging - Google服务示例Gradle未知错误

Question

我从这里下载了Google服务示例,当我尝试按照有关JSON的步骤运行它时,会弹出一个错误.问题是控制台和日志没有显示此错误.

看起来像这样.

我不知道我做错了什么,但在此之后,我不能再尝试再次运行它,因为Run按钮被禁用了.

有什么想法解决这个问题？

更新:这是Gradle控制台中的日志:

Answer 1

这对我有用:

在build.gradle(app)中我有

applicationId "com.examples.Activities"

在google-services.json我有

"package_name": "com.examples"

我变了

"package_name": "com.examples"

至

"package_name": "com.examples.Activities"

Answer 2

我遇到了同样的问题。

我的解决方法是修改文件“build.gradle(Project: gcm)”。

在 build.gradle 文件中（项目：gcm）

buildscript {
...
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
        classpath 'com.google.gms:google-services:1.3.0-beta1'// downgrade it version
    }
}

希望这会对您有所帮助。
