While developing an Android app, you would usually run it on a physical device or an emulator. If you want to share it with someone for their feedback, you would share an APK that can easily be installed on any Android device.
- This APK can only be used for testing. For deployment, you should generate a signed APK for which the process is a little more complicated.
- You need to enable the “Allow unknown sources” option in the settings of the device where you want to install the APK.
