Android Question Phone pc connection

[renzo13]

Hi, years ago I created a B4A app to view data from an access mdb file. It has always worked with all Android phones, with versions from 5 to 13.
Now I bought a Samsung S23 with android 14 and I couldn't install the old APK (see screenshot 1,2,3).
I then decided to install the B4A compiler again on my new PC and new S23 phone.
After the installation I cannot connect the PC to the phone because the PC enters an infinite loop of: [connection attempt] - [connected].
I made many attempts with different PCs, phones and wi-fi networks.
What can I do?
Thanks for your help.

Try to enable developer options on your phone, and then connect the phone to your pc via USB

Hi, I had already enabled developer options. I didn't specify that all my PCs use Windows 11. Is it possible that this is the problem?

Sorry, I'm a bit confused here.
Your problem is to connect your phone with USB-Bridge?
What's the Agenda App? The first screenshot I thing is saying your app (Agenda) is not secure, but you can install it anyway pressing (Altri dettagle) and the somthing like: "install anyway". But, how is related the screenshots with your problem?

Please, read all the differences with the new updates in different Android versions

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...

By the way, the italian community is very active and helpful in this forum. Maybe they can't help better with your screenshots
