Application build and deployment

• Developer Community 1288717:
  Support Fast Deployment for System Applications.
  Added support for fast deployment while building system based
  applications. Applications developed in this mode need to be
  signed with a platform key and set
  /manifest/@android:sharedUserId
  to android.uid.system within AndroidManifest.xml:

          <manifest xmlns:android="http://schemas.android.com/apk/res/android"
              android:sharedUserId="android.uid.system"
              …>
          </manifest>

• Developer Community 1363149:
  System.ArgumentException when %PATH% or %PATHEXT% contain ".

• GitHub PR 5304:
  Add support for producing a ProGuard mapping.txt file to the build system.
  This file can be used by users to remove this warning:

  "This App Bundle contains Java/Kotlin code, which might be obfuscated."
  

  ... when uploading packages to the Google Play Store.

  In order to opt-in to this behavior, set the AndroidProguardMappingFile
  MSBuild property in your project file to the path of the file you want
  generated:

  <PropertyGroup>
    <AndroidProguardMappingFile>$(OutputPath)\mapping.txt</AndroidProguardMappingFile>
  </PropertyGroup>
