I built a new Android app in the MIT AI2 program. I just tried to publish it on the Play Store, using the Google Play Console. When I tried to upload the .aab file, I got this error :
Your Android App Bundle uses an upload certificate with a key that is too weak.
What can I do in AI2 for this one?
I have built and published an app that is a very original idea. But, I cannot put ads in it. But, I have high hopes that I can still make some money with it. So, I wish to ask if it's possible to sell a published package to a different company? Should I try to ask someone at Google?
