I am trying to publish my app

[Genaro_Cardenas]

I got this error on play console:

"At this time, the app targets API level 30. To ensure that it is based on the latest APIs that are optimized for security and performance, it must target API level 31 at a minimum. Your app's target API to at least 31."

What can I do?

Uploading the app on playstore problem

Sorry, you must wait until MIT releases nb190 sometime this month, only then will you be able to easily create an api targeting level 31.

How can I check if MIT update the target?

Go to Help > About in the MIT App Inventor website.

Target API level 31

Not really a "simple" solution: Build the APK. Decompile it. Edit the Manifest and add android:exported="true" to each <activity ... > and <receiver ... >. Set targetSdkVersion = 31. Recompile it. Check if the app (APK) can be installed on your test devices. If so, convert the APK to AAB: Convert APK TO AAB File - Guides - Niotron Community (otherwise check if you missed to add android:exported="true" to every <activity> and <receiver> and continue with step 4).

Here is a "solution" I found.
