什么是Android Studio 4.1中的navigation.json? [英] What is navigation.json in Android Studio 4.1?

问题描述

我今天刚刚试用了Android Studio 4.1.我启动了Android Studio，并创建了空的活动，然后使用android虚拟设备运行了它.然后失败了，并显示此错误:

I just tried out Android Studio 4.1 today. I started the Android Studio and created empty activity and I run it using the android virtual device. Then it was failed and this error is shown:

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':app:processDebugManifest' (type 'ProcessMultiApkApplicationManifest').
> File 'E:\Project\AndroidLayout\app\build\intermediates\merged_manifest\debug\out\AndroidManifest.xml' specified for property 'mainMergedManifest' does not exist.

当我重建项目时，错误消息显示在这里:

When I rebuild the project, the error message is shown here:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugMainManifest'.
> com.android.manifmerger.ManifestMerger2$MergeFailureException: java.io.FileNotFoundException: E:\Project\AndroidLayout\app\build\intermediates\navigation_json\debug\navigation.json (The system cannot find the path specified)

请注意，这是全新安装和全新项目，无需对代码进行任何修改.

Note that this is fresh install and fresh project without any modification in the code.
