I tried to use Google In-App Updates library in my application that already in the Playstore. But i have some problems about how to test it. I am not gonna use FakeAppUpdateManager since there are no UI is being shown and no update is really performed
First, I cannot test it with debug build even if i set the versionCode lower than Playstore version code because of different keystore.
Second, According some tutorials said that i must using release build and signed with same keystore that i use to upload on Playstore. but when i did that, i still didn't get any in-app update. My guess is: because i used Google App Signing so the fingerprint is different and it is not recognized as same application (let me know if i am wrong about this).
Is there any elegant way to test this out?
