ERROR | detected a hanging thread 'QEMU2 main loop'. No response for 20246 ms

[ludovicroland]

Hello,

I am trying to use this action in order to run instrumented tests on my multi-module application using this configuration:

- name: run android tests
  uses: reactivecircus/android-emulator-runner@v2
  with:
    target: google_apis_playstore
    arch: x86_64
    api-level: 35
    script: ./gradlew runAndroidTests

The runAndroidTests task is a custom gradle task that depends on Jacoco tasks:

target.tasks.register("runAndroidTests") {
      dependsOn(
        ":ads:createFubukiGoogleDebugCoverageReport",
        ":app:createFubukiGoogleDebugCoverageReport",
        ":cookies:createFubukiGoogleDebugCoverageReport",
        ":core:createFubukiGoogleDebugCoverageReport",
        ":game:createFubukiGoogleDebugCoverageReport",
        ":home:createFubukiGoogleDebugCoverageReport",
        ":licenses:createFubukiGoogleDebugCoverageReport",
        ":notifications:createFubukiGoogleDebugCoverageReport",
        ":our_apps:createFubukiGoogleDebugCoverageReport",
        ":release_notes:createFubukiGoogleDebugCoverageReport",
        ":settings:createFubukiGoogleDebugCoverageReport",
        ":shop:createFubukiGoogleDebugCoverageReport"
      )
    }

It seems that the emulator is launched correcly, but my custom task takes time to configure everything before launch the tests and it alway fails with the following error message:

ERROR        | detected a hanging thread 'QEMU2 main loop'. No response for 20246 ms
ERROR        | detected a hanging thread 'QEMU2 main loop'. No response for 16787 ms

I also tried to run another gradle task on the script part:

      - name: run android tests
        uses: reactivecircus/android-emulator-runner@v2
        with:
          target: google_apis_playstore
          arch: x86_64
          api-level: 35
          script: ./gradlew :ads:createFubukiGoogleDebugCoverageReport

But the result is exactly the same and it fails on the same task:

> Task :ads:mergeExtDexFubukiGoogleDebugAndroidTest
ERROR        | detected a hanging thread 'QEMU2 main loop'. No response for 18296 ms
ERROR        | detected a hanging thread 'QEMU2 main loop'. No response for 17744 ms

Have you tried an older API level? Also curious if you're running the action with linux or macos runner?

[ludovicroland]

Hello,

I tried with the api-level 34.

It failed too, but I do not have logs about an error with the emulator.

It seems that github action just stops to work during the tasks configuration of gradle. I do not have any logs.

I am seeing the same as @ludovicroland. It seems to stop during the tasks configuration of gradle. I'm running against api 29.

[JesusM]

I'm seeing this issue too (API 29)
