Root detection on Android device using MAUI .net framework

Question

The Android root detection logic implemented in .NET MAUI is not working as expected.

Tried both a custom implementation and a NuGet package as in link below, but both approaches failed.

nuget package > https://www.banditoth.net/net-maui-jailbreak-and-root-detection/

Root status is determined by checking for the presence of su files on the device. When inspecting a rooted emulator via adb shell, these files were found, confirming that the emulator is rooted.

However, when executing the same logic in code, the File.Exists check fails to detect the su files.

It is unclear whether the app needs elevated permissions to access system folders for root detection. Additionally, it is not yet confirmed if this issue is specific to emulators, as the logic has not been tested on a physical device.

Any help here is greatly appreciated.

Answer 1

Hello,

Monitoring Root is a dangerous behavior. According to community policy, I cannot provide you with relevant methods. The official method recommended by Google is to check integrity through Google Play Integrity. You could refer to the following documents and Nuget Package.

• Google Play Integrity API documentation.
• Google.Apis.PlayIntegrity.v1.

Best Regards,

Alec Liu.
