我只在Signed APK构建过程中遇到构建错误。以前签署的APK构建工作没有问题。自上次签署APK Build以来，唯一的变化是我已经更新到新的Android Studio 3.6-Build#AI-192.7142.36.6200805。
生成输出为：失败：生成失败，出现异常。
- 出了什么问题：任务"：app:packageDebug"的执行失败。
执行com.android.build.gradle.internal.tasks.Workers$ActionFacade时出错条目名称"播放服务广告标识符.properties"与冲突

我不确定如何更新或解决：app:packageDebug问题？和/或识别play-services-ds-identifier.properties冲突？
我似乎已经通过删除位于app/debug目录中的apk和json文件解决了这个问题。
删除后，已签名的APK生成成功完成。
删除appbuildoutputsapk(debug和release(目录中的所有文件夹。然后是clean project、rebuild project，最后是Run您的项目。在我的情况下，我也面临着在模拟器中运行APK的问题，我通过这样做解决了这个问题
通过转到Build -> Clean清理构建为我修复了它。
我观察到gradle版本的问题：com.android.tools.build:gradle:4.1.0
在项目级build.gradle文件中将版本升级为4.1.2，如下所示，然后在运行Build->Clean后再次生成apk，没有出现错误(在我的情况下，没有版本升级的情况下只是清理并没有解决错误(：
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.1.2"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
