support for library projects

[trevjonez]

As far as I can tell this step assumes the typical apk pair or triple that you would see in an application project [main, test] or [main, test, orch]. In and module that uses com.android.library it is possible to build a single test apk which also includes the contents of the AAR library for testing.

Either I am being too lazy about reading the docs or there is not way to do this without some questionable workarounds happening.

Hi @trevjonez !

Thanks for the request.
I have made a ticket for the Tooling Team. They will check it.

I don't remember if I read this somewhere but I gave it a try and it has been working for us for about 3-4 months running connectedDebugAndroidTest on a library module. You just have to add a step to actually build the library module test apk. For our api library module:

  - gradle-runner:
        inputs:
        - mapping_file_include_filter: ''
        - apk_file_include_filter: ''
        - gradle_task: api:assembleDebugAndroidTest
        title: Build api module instrumentation test apk
    - virtual-device-testing-for-android:
        inputs:
        - test_devices: "$INSTRUMENTATION_DEVICE_LIST"
        - test_type: instrumentation
        title: Run api module instrumentation test on virtual devices

Just know that if you are going to run this for a library module and an app module in the same workflow you may experience the problem I faced in #24

I'm wondering if this is still in consideration or if there's a simple workaround. I see this issue thread relating to the Android Build for UI Testing step.

This issue is still unresolved and should not be marked as stale automatically.

You also have to link a random apk next to the test apk generated or else virtual-device-testing-for-android fails, e.g. this small apk or one you generated from a sample app of yours:

Add this step between assembleDebugAndroidTest and virtual-device-testing-for-android:

   - script@1:
        inputs:
        - content: |-
            #!/usr/bin/env bash
            set -e
            set -x
            wget https://some_place_you_uploaded_the_apk_to.apk -O $BITRISE_DEPLOY_DIR/dummy.apk

            envman add --key BITRISE_APK_PATH --value "$BITRISE_DEPLOY_DIR/dummy.apk"
        title: 'workaround: dummy APK'

I also am having this issue. The step looks for an apk in a library project, I think it should be fixed.

@mateherber do you have any news on this? I see that @tothszabi already fixed the problem, but the change was never released ☹️
