I have an existing app in google play store with many users
As B4A v12 was released I updated my B4A to v12
Trying to open the project with v12 and compile it generated many errors, on another post I was recommended to add the line #multidex: true – that resolved the issue and my app was compiled and an APK was generated
Then to test it I tried to update the app on my phone – got an error that the APK is not compatible
tried it with a few other devices – same result
a new app with compiled with v12 wont update an existing v11 app
Tried to compile on another machine still with v11 – all is perfect (removed the multidex: true line)
Made another test – took another app that required multidex: true as this one (the other is a small non commercial app so I could "play" with it – compiled it with a lower version number, removed it from my device and installed...
