在向应用程序添加 ArCore 支持并在清单文件中设置com.google.ar.core为optional后（如下所示），我看到 Play 商店预发布测试似乎只在支持 ArCore 的设备上运行。还有人看到这个吗？

    <meta-data android:name="com.google.ar.core" android:value="optional" />

我刚刚将项目（和 AS 插件）更新到 Kotlin 1.3.50，现在遇到如下构建错误。还有其他人遇到过这种情况吗？我正在使用 Android Studio 3.5。

更新到AS 3.0 beta 6后,我开始收到以下错误.有没有其他人遇到此问题？当我尝试从AS构建/运行时,我只看到此错误.....如果我在命令行上运行gradle,则没有问题.

Execution failed for task ':app:transformDexArchiveWithDexMergerFor<BuildVariantName>Debug'.

我有一个多模块项目(支持即时应用程序和已安装的应用程序).当使用AS 3.0 RC1和RC2时,我无法再启动应用....

Default Activity not found

我有许多产品口味和问题可能与每个口味LAUNCHER宣布适当活动的事实有关AndroidManifest.xml(我在"构建变体"部分中选择了其中一种口味).这一直在AS 3.0 Beta 7上运行良好.
