Java or Kotlin are not the only languages you can use to create apps for Android. C# programmers can develop mobile apps using the Xamarin open-source platform. Today, I will explain how to research such apps and find ways to hack them.

Android has a wonderful feature: you can make any program the provider of geocoordinates, so that the entire system will use the latitude and longitude provided by it. In this article, I will show how to exploit this feature and how to write a program spoofing GPS coordinates.
