Links and differences between Android package properties, package name and application ID

1. Package properties: In the Androidmanifest.xml file.
2. Package Name: The bundle name of the module structure.
3. Application ID: The ApplicationID property under the module Defaultconfig block.
   1. Each Android application has a unique application ID similar to the Java package name
   2. If you want to upload a new version of the application, the application ID must be the same as the original. If you change the application ID of the new version of the application, then the Goolge store will consider it a completely different application
   3. The application ID and package name are exactly matched. In addition, the two are completely independent. Of course, you can change the package name, but this does not affect the application ID. Vice versa
   4. • A minimum of two segments (at least one. Separate)
      • Each paragraph must begin with a letter
      • All characters can only be letters, numbers, and underscores
