Is the source code of any application on Android Play Store visible to users after downloading it?

No, the source code of an application on the Android Play Store is not visible to users after downloading it. The application code is compiled into an executable binary file that is distributed to users as an APK (Android Package) file.

The APK file contains the compiled code, as well as any resources such as images, sound files, and other assets used by the application. When the user installs the application, the APK file is unpacked and installed on the device, but the source code is not accessible to the user.

Access to the source code is typically limited to the developers who created the application, and they may choose to keep it private or share it with others through a version control system like GitHub or Bitbucket. However, it’s worth noting that some developers may choose to release their application as open-source software, in which case the source code would be publicly available for anyone to view and modify.
