Steps to Reproduce

  1. Install src/Mono.Android/Test/Mono.Android-Tests.csproj to a v4.4 or lower target in release mode.
  2. Run the suite with instrumentation via the /t:RunTests msbuild target.

Alternatively, I've uploaded the .apk file which can be installed via adb. I was able to reproduce with this .apk on a newly created v4.4 emulator.

  1. Download the .apk provided below, and adb install it.
  2. Launch the app, and click the Run Tests list view item.

Mono.Android_Tests-Signed.zip

Expected Behavior

NUnitLite suites will start and run successfully via instrumentation.

Actual Behavior

Crash on start up:
