Description

In an app we collect device sensor data, such as geolocation, connectivity status and battery info.

Trying out .NET 8-preview 5 because it has an event-based Geolocation sensor implementation (see #9572), we notice that, when the app is built in Release mode, the interface randomly freezes and produces an ANR.

Steps to Reproduce

This happens both on the emulator as on actual devices.
The problem can be reproduced with the sample app.

  1. Make sure you build and run the sample in Release mode.
  2. In the advanced settings of the emulator, under Location, configure a route and make it play on repeat.
  3. Wait a bit. The issue occurs to anywhere between 30 seconds and 5 minutes for me.
  4. Click anywhere on the main page, or to make it more clear, try to open the flyout menu.

These interactions will freeze the application, leading to an ANR shortly.

I let the app (built in Release) run for a few minutes on a Pixel 5 and an emulator, but I'm not getting an ANR. I can tap the flyout.

Can you share the route file (GPX/KML) you're using here?

Sample_route.zip

I'm not sure what happened, but just like you're showing in your screenshot, the Location feature of the Extended Controls in my Emulator has broken. The map in both the Single Point and Routes tab doesn't show, and I can't load a saved route, nor import an externally created route. I've attached a test route either way, but the emulator might also not load it for you as well.

You can however just run the app on a local device, and walk around for a bit. After a few location updates, the app also crashes as described.

[Edit]: I seem to get it more quickly when I change the location permission from "Allowed only while in use" to "Allowed all the time".

Yeah, I can't get the routes to work in the emulator either. It just spins forever loading the file...

So, I tried on my Pixel 5 device, but the app also seems to be working.

I think you could enable Mono's tracing and the runtime will log every method called:

# clear the log
adb logcat -c
# enable tracing
adb shell setprop debug.mono.trace all
# run the app again, cause an ANR
# save the log
adb logcat -d > log.txt

You should see lines like this:

The class that looks questionable to me is CircularBuffer<T>. It seems like it could deadlock causing a problem like this.

Tracing will make the app very slow. To clear this later you can either reboot the device or run adb shell setprop debug.mono.trace "''".

I was able to produce such a log with an ANR, the dump starts at timestamp 08-22 00:53:17.166.
mono_trace_log.zip

As to your comment about CircularBuffer<T>, it's been a while since I created the repro sample, but I've definitely been able to reproduce this without the AccelerationInfo.Start() being invoked. I've tried disabling all the various sensor sources one by one, but kept getting the crash without being able to identify a single perpetrator, that's why I left them all in.

To reproduce on my real device, I need to receive about three location updates, which requires me to walk ~50m.

I had the app running on a Pixel 5 and drove around the block, and it was working? I'll look into your logs tomorrow, thanks.

One difference, is I'm using dotnet/maui/net8.0 branch and all the versions here, so these are nightly RC 1 builds of everything:

Hmm, it appears the last managed method is about 10 seconds from the ANR:

So, it's in native code/runtime side where things are stuck. Somewhere in __icall_wrapper_mono_gc_alloc_obj.

@lordstyx are you using .NET 8 Preview 7? We disabled a feature in Release mode in the latest release:

dotnet/android@6836818

Can you try the latest release? Or set <AndroidEnableMarshalMethod>false</AndroidEnableMarshalMethods> in your project?

I had so far still been using preview 6, from when originally reporting the issue.
After updating to preview 7 I can no longer reproduce the issue with the provided sample app.

In our actual app we also notice a big reduction in ANR's when building with preview 7, but they're not completely gone.
That might however be unrelated, and with the emulator's location simulation being broken it'll take some time to figure out what that is. Until then I think this issue can be closed.

Thank you.
