AI2OFFLINE custom package name

[chrisosallos]

Hello there, i used http://ai2.appinventor.mit.edu/ to made a project, when i dowload the apk, works totally fine in my mobile but when i use AI2OFFLINE and change apk package name to com.name.name and i dowload the apk then when i install it in the mobile, crushes when i open the app. Please help?

[chrisosallos]

UPDATE when i load an aia project from the original site to AI2OFFLINE and a build and apk then the apk doesn't work in mobile. just crushes all the time.

Package name - how do you set a custom package name?

In order to be able to release an app in the Play Store, at least the following requirements must be met: The version code is higher than the current version. The packageName is the same (as the previous / original one). The keystore is identical (with the previous / initial version). The targetSdkVersion corresponds to the minimum SDK required by Google (from Aug 2021: SDK 30 for new apps and from Nov 2021 also for updates).

The packageName with AI2 (online version) is:
appinventor.ai_<email>.<projectName>
In my case e.g.:
appinventor.ai_bodymindpower.Relax

The packageName with AI2Offline is:
com.<email>.<projectName>
In my case e.g.:
com.bodymindpower.Relax

Note: → AboutScreen
AboutScreen must be empty on all screens and must not be used with blocks either, as AI2Offline has removed this property.

I make a build in AI2OFFLINE, i download the apk and i try to install it in my phone. But when i go to open it, crushes. All about screens are empty and i dont know what to do.

1. Export the aia from AI2Offline and import it with AI2 (online). Build the APK, install it and try ...
   Does it crash?
2. Show the Screen1.Initialize event block.

[chrisosallos]

Okay i did this but in the AI2OFFLINE, i custom the package name and when i loaded in the AI2ONLINE the aia file it changed again the name of package to the appinventor.ai etc

If you wish post your aia here, I just tested a simple project, compiled with AI2OFFLINE, installed it and no crash. Also why are you saving components in tinyDB ?

[Anke]

I checked your aia with AI2Offline.

1. As I said before, AboutScreen must be empty in all screens.
2. There seems to be an issue with Firebase:
