SIGSEGV crash in AccessibilityService when using HttpClient #2904

Closed AdmiralSnyder closed 6 months ago

AdmiralSnyder commented 5 years ago

Steps to Reproduce

Error occurs in Emulator, Android 8.1 - API 27.

Context: I build an AccessibilityService that sends its event to another system via HttpClient.PostAsync.

The service must be activated in adb shell with $ settings put secure enabled_accessibility_services App2.App2/App2.ResearchAccessibilityService

App2.zip

Expected Behavior

Don't crash, or at least give me a C# stacktrace.

Actual Behavior

After a couple of successful POSTs, it randomly crashes (Got a SIGSEGV while executing native code.), but the managed stacktrace errors with "domain required for stack walk" (which originates from https://github.com/mono/mono/blob/master/mono/mini/mini-exceptions.c, because some domain is not given --> is this another error needing another Issue?)

the last line of the output is: 03-31 13:10:53.031 F/libc ( 8639): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x50 in tid 8690 (OkHttp Dispatch), pid 8639 (App2.App2)

The problem occurs both when I use the Android HttpClient implementation and the Managed one.

With support for Classic Xamarin.Android ended May 1st, 2024, this issue is likely no longer relevant.

If this still persists in .NET 8+, please open a new issue with updated information based on net8.0-android or greater. Please include a link to this issue for context.
