Why each option
Android applications are packaged and distributed as .apk (Android Package Kit) files, which is the format the Android operating system uses to install apps.
.app is the macOS application bundle format used by Apple's operating system and is not recognized by Android.
APK (Android Package Kit) is the file format Android uses to distribute and install applications; it is analogous to .exe on Windows or .app on macOS. When sideloading outside the Play Store, a technician selects the .apk file through the device's file manager or a GUI installer. The Android system parses the APK, extracts its components, and installs it to the device storage.
.exe is the Windows Portable Executable format and cannot be executed on an Android device.
.sh is a Unix/Linux Bash shell script format; Android does not use shell scripts as its standard application installation format.
