Deploy an Android application
Simpler than iOS, there are 2 solutions to deploy an application on Android devices: publish it on the Google Play Store or distribute it outside (it is an application from an unknown source).
Publish on Google Play Store
- Your application must comply with Google's constraints, particularly in terms of audience (measures are reinforced to protect the youngest audiences).
Distribute an application from an unknown source
- The user must authorize the installation from the Settings menu of his Android device.
