在将PlayService版本更新为12.0.0之后，无法运行该应用程序

Question

在将播放服务版本更新到12.0.0之后，我在尝试构建这个应用程序时遇到了问题，但是它在11.8.0版本中运行得很好。在app中找不到绑定文件夹。

消息:

错误：(20，38)错误:包com.app.test.databinding不存在错误：(31，13)错误:找不到符号类MainFragmentBinding

Note当我将游戏服务和火基版本降级为11.8.0时，我能够运行

Answer 1

我也有同样的问题(只是使用一些基本的东西，而不是数据库)。使用11.8.0，但是当更新到12.0.0时，它不再编译了。

在意识到我有一个旧版本的play-services-auth之后，我能够修复它。这必须与火基版本相匹配。

当来自不同模块和库的依赖项来自不同的模块和库时，我使用resolutionStrategy (参见http://stackoverflow.com/a/42718231/2170109)来克服这个问题：

project.configurations.all {
    resolutionStrategy.eachDependency { details ->
        if (details.requested.group == 'com.google.firebase'
                || details.requested.name.contains('play-services-auth')) {
            details.useVersion "$playServicesVersion"
        }
    }
}

Answer 2

将构建工具更新为3.1.0，并尝试将google()存储库添加到项目build.gradle：

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'
    }
}
...

Answer 3

清理和重建项目。大多数时候我这么做的时候。它解决了所有问题。
