MAUI Android Memory Profiling (Heapdump)

Edwood Able 0

We have a memory leak in our MAUI Android app and are trying to find the cause of it. Xamarin.Profiler doesn't work anymore and I can't make a lot of sense of this documentation:

https://github.com/dotnet/maui/wiki/Profiling-.NET-MAUI-Apps

https://github.com/xamarin/xamarin-android/blob/main/Documentation/guides/tracing.md ("If running on desktop, you can use the dotnet-gcdump global tool" - I don't understand why they added this paragraph to "xamarin-android" documentation - no I'm obviously not running an Android app on desktop?!)

So are there any memory(!) profiling options? How can we find the cause of memory leaks?

You can run your application in android device or emulator, and you can get and analysis your dump file by .NET command line in the windows from tracing.md document. Not running an android app on desktop.

The general process is to open an emulator in VS or connect to your android device by USB. Then open your adb command line (reverse port and profiled app suspends until tracing utility connects) in windows platform. If you build and run your application, you can get the /tmp/hellomaui-app-trace file and open a CMD to analysis your dump file by .NET command line in the windows.

Thank you, I overlooked the "To get this data from an Android application..." paragraph. I managed to obtain and analyze a heapdump using the tracing.md doc. Very cumbersome process though - but better than nothing.
