• Launch an android emulator

  • Option 1: open the Device Manager window of Android Studio and click on the triangle

  • Option 2: start an emulator from the command line (part 2.5)

• If you run the testrunner for the first time, you have to run it once without the --no-update option:

  • On Linux and macOS: ./testrunner -jobFile job.yml -config config.yml

  • On Windows: testrunner -jobFile job.yml -config config.yml

• Download the android-service executable in 32 bits and its version file : https://dl.greenspector.com/emulator/android-service-files.tar.gz

• Go to your greenspector cache:

  • On Linux and macOS: $HOME/.greenspector

  • On Windows: C:\Users\[username]\.greenspector

• Replace the android-service and android-service.version files with the downloaded files. You will have to decompress the tar.gz file.

• You can now run the testrunner with the --no-update option:
