App is not installed as an update

Hi,
I imported an app built with appybuilder into appinventor

why when i install the apk compiled with inventor, the app is not installed as an update but as a new app?

You will have a different package name.

ok I imagined it ...
is there any way to fix?

Try to use AI2Offline download | SourceForge.net

The (default) package name with AppyBuilder is:

com.appybuilder.<email>.<projectName>

There is no way to get this package name with AI2 or AI2Offline.
You have to change it manually (by de-/recompiling the apk) or you can use Kodular.
