How internal tester can download the "Android" pre-released App build?

Question

Could anyone plz let me know, How internal tester can download the "Android" pre-released App build ? Because now "TestFlight" is only for iOS as acquired by Apple. Whether, solution is to upload the Android pre-release app build on "Google Play" and invite internal-tester to get download. **Earlier I used "TestFlight", I downloaded pre-released app build on iOS7 device, the distributed by Developer for internal testing. Thanks,

Answer 1

Use opt-in URL, which is generated in the "Internal test" area of Google Play Console, after completing all the publishing steps

Answer 2

My mistake was to look at the wrong place for the publishing status.

I looked at the status of the internal track release itself, instead of looking at the release status of the app (located in App-Releases in the dropdown at the top). So the app wasn't released yet, thats why the internal track release didn't have a participation-URL in the tab with the testers list.

CLARIFICATION

As suggested by the comment below, here some screenshots from my android console. The status that I looked at was the status of the internal track release:

The one I should have looked at, was the status of the app itself:

These are two different states!

After both are released, you can create a list of testers for your internal test track and give them the link provided in the console:

ADDITIONAL INFO

It seems like the above mentioned indicators might only be right for the initial launch. I've updated the app and tried to download the new version as a tester. However, instead of getting the new Version (0.0.10) I got the old, non-updated version (0.0.9). So, maybe wait for the notification in the console that tells you that the shop entry has been updated. Could take a few minutes (hours?).
