Target API level 31

[Anke]

@UgoPiazza

I assure you, I have created and uploaded several new apps in the last few days

It may be that there was a delay with the error message. This doesn't change the fact that from Aug 1st 2022 no new apps can be released with targeSdkVersion=30.

@UgoPiazza

If you have a simple solution to change the target API of apps created with app inventor I would be grateful.

Not really a "simple" solution:

1. Build the APK.
2. Decompile it.
3. Edit the Manifest and add
   android:exported="true"
   to each <activity ... > and <receiver ... >.
4. Set targetSdkVersion = 31.
5. Recompile it.
6. Check if the app (APK) can be installed on your test devices.
7. If so, convert the APK to AAB:

   (otherwise check if you missed to add android:exported="true" to every <activity> and <receiver> and continue with step 4).

Hi and thanks for all your answers love this forum

5/8-2022 I did release this app to Google Play: https://play.google.com/store/apps/details?id=appinventor.ai_teddybrask.NASA_pictures as a new app.
I will try @Anke' solution later this day to see if I can get it to work.

good evening, do you know if app inventor will update the configuration so that new apps come out with the api31 form? Cheers

@mariano_stemberg

do you know if app inventor will update the configuration so that new apps come out with the api31 form?

The AI2 team is working on the targetSdk 31 update and I think it will be available soon.

You currently only have two options:

1. Waiting for the targetSdk 31 update or
2. follow my instructions.

Hi, @Anke thanks for your support.
The Manuel way is quite time-consuming (for me ) and is pointing out how strong a product app inventor really is! HOPE the team has plenty of strong coffee and that the next update is available soon

Hi, I have over 90 educational apps published and this morning (August 10th) I encountered the same problem. Google play now requires API Level 31. We've been through this before, especially when they stopped accepting APK and started requiring AAB. There are options to try to generate the AAB File on the KODULAR Platform. Just import your AIA file on that platform, but I believe they are also using API Level 30 there. I suggest waiting for the update of the great platform, APP INVENTOR.

I hope I was helpfull.

@111330

how can sign aab file with my keystore??

How to build a big app → APK max. 100 MB or → AAB 150 MB

Steps to build a big app for APK → max. 100 MB or AAB → max. 150 MB (new, added on Aug 31, 2021) 1. APK (Note: apps that were released before Aug 1, 2021 can still use APKs !) You can use e.g. APK Editor Studio for that. First download the keystore "android.keystore" from your AI2 account and rename it to: "android.ks" remove some big files (png, jpg, mp3,…) from the assets (AIA < 10 MB, better < 5 MB) build APK decompile APK (re)insert the missing files to the assets recompile your …

Thank you

If your project is urgent, maybe you can get a temporary solution through http://ai2-test.appinventor.mit.edu, but it should be noted that there is no guarantee that the built app can run stably on android 12 currently.

[SteveJG]

Robert, a developer can do this however he/she still needs to wait for the arrival of nb190 later this month. Your suggestion can be used to test the creation of the aab however it is NOT SUITABLE for submission to Google Play yet.

[ewpatton]

Just to clarify a few things since there appears to be a bit of confusion in this thread.

1. AAB build support is available in production App Inventor, and has been for a while now.
2. Only new apps need to target SDK 31 at this time. Existing apps that are updated have until Nov 1, 2022 so this does not affect any previously published apps.
3. As mentioned, we do have a test version at ai2-test that targets SDK 31 as part of our summer upgrade. It's important to manage your keystores properly if you plan to use that server in the interim because it is a completely separate system from ai2. While we believe this system is mostly stable it is a beta version and may not meet your needs.

Hello
I do all the steps that @Anke tell me and
I update in the manifest to target 31 and i convert to aab file then I sign it with the mit app inventor keystore
When I publish to google play this message show to me
You uploaded an APK or Android App Bundle which has an activity, activity alias, service or broadcast receiver with intent filter, but without the 'android:exported' property set. This file can't be installed on Android 12 or higher

I think this is a second problem
I hope you solve the problem because ai2 is very important for me

[Anke]

@111330

receiver with intent filter, but without the 'android:exported' property set

See my post → #13

[Anke]

Import your project (aia) to http://ai2-test.appinventor.mit.edu/ and build the APK and check the Manifest (compare it with your edited Manifest).

You can also try to create the AAB (on the test server) and upload it to Google Play (developer console) as an internal test track and wait for the Pre-launch report.

[Anke]

Note:
If your app is a new app (and only in this case you must target SDK 31), you do not need to import the keystore from AI2. You can use the new keystore that the test server generates for you.
