Execute code before the application install

[nikitin-da]

Is your feature request related to a problem? Please describe. Hello! Is there ability to execute some code before the target app installation? For instance, I want to add test for appsflyer non-organic install So that I needed to

1. Open an attribution link
2. Install the app
3. Verify attribution Appsflyer checks if the app already installed, if so test wont pass

Describe alternatives you've considered Of course I can execute this code as an extra step in the CI pipeline but I know nothing about particular test requirements on this stage. So in this case I have to create an additional parameter or CI job just for this particular test.

Also it seems we can't uninstall target app during the test. "adb uninstall " breaks the test (works fine for another apps only)

Additional context Android, Kaspresso

Random code execution is supported by creating pull requests or forking and implementing the code.

What you describe as a test doesn't sound like an Android instrumentation. Implementing a plain JUnit test that communicates directly with adb and does precisely what you want is the best approach.

For example, to simulate forwarding of a particular referrer, you can send the broadcast:

am broadcast -a com.android.vending.INSTALL_REFERRER -n com.your.package/com.your.package.CustomInstallTrackersReceiver --es "referrer" "hello%3Dworld%26utm_source%3Dshell"

The lifecycle of your test outlives the instrumentation lifecycle (this is why you can't uninstall the apks under test), so either way, you have to use another process: it might be much easier to use something like a plain JUnit test or if you want to go the hard way, create another apk on the same device that triggers this test similar to how orchestrator does it.

I think it is easier to prepare environment on CI instead. Not sure about INSTALL_REFERRER broadcast manual emulation. Thank you!
