You need to change the name of the app from "example" to what ever you want it to be, and also change the publishing key, they are unique to each app

The "Package" name (IDE...Project...Build Config) needs to be unique for each app you write.

Thanks, changing the "Package" sorted it out but interesting about the publishing key - I haven't published anything on Google Play but will keep that in mind.

Click to expand...

The key represents "you" as a developer and is always the same for every app. Only with the same key you can upload a new version. The package name (similar to a file name) must be unique and different for each app but keep in my that this means for ALL apps in the world (=unique package name worldwide). Mostly you use a name like uk.acuariosmith.yourappsname for your packagename.

Ok, thanks, got that.
The problem I now have is using my own key I can't install the app on my phone using B4A-Bridge as detailed in #6 here https://www.b4x.com/android/forum/threads/blocked-by-play-protect.114898/

You might need to turn off Play Protect (from within the Play Stores app's settings).

Then down the road when you successfully publish your first app in the play store, google will then know your "private" key and should recognize you as a developer from that point on.

Another reason you may not be able to install the new app is that you have the previous app installed (that has the same packagename) but was signed with the old key.

If this is the case, then just uninstall the previous version of the app and then try doing a clean install of the new app so everything is in sync.
