Question

我尝试调试应用程序，但出现此错误

任务'：app：preDebugBuild'的执行失败。

Android依赖项'com.google.android.gms：play-services-tasks'对于编译（16.0.1）和运行时（17.0.0）类路径具有不同的版本。您应该通过DependencyResolution手动设置相同的版本

有人可以帮助我吗？谢谢

Answer 1

只需添加以下依赖项应用returnVal = null

build.gradle

Answer 2

我通过将其添加到应用程序构建gradle中来解决此问题

implementation 'com.google.android.gms:play-services-tasks:17.0.0'

但它也跟随另一个错误，并通过使用此方法解决了

implementation 'com.google.android.gms:play-services-base:17.0.0'
implementation 'com.google.android.gms:play-services-basement:17.0.0'

也许还有另一种方法可以将所有播放服务版本设置为17.0.0

Android依赖项'com.google.android.gms：play-services-tasks'对于编译（16.0.1）和运行时（17.0.0）类路径具有不同的版本
