Android Question Update version of application

[jota1010]

Good morning, afternoons or evening.

I have installed the version 1.0 of an application on a device through B4A-Bridge, but now I need to update the version of the application remotely and also check every time you start if updates are available.

Another situation is that I have a database and When it upgrade the application, the base must not undergo no changes.

Answer to second question: If file exists - don't overwrite it (base must not undergo no changes) .

If File.Exists(File.DirDefaultExternal, "QI.db") = False Then
        File.Copy(File.DirAssets, "QI.db",File.DirDefaultExternal,"QI.db")
        Log(" Copying QI.db to SD card")
End If
