replace jcenter with mavenCentral and gradlePluginPortal

Make it easy for the year 2025

• jcenter has been retired some years back and we need new plugin repository
• Opening the project with Android Studio 4.2.2 should be a foolproof starting point

@vikoadi hello! I'm developing an app for Android 1.0 and I use Android Studio 2.3.2.

Starting with Android 2.2, the XML signing algorithm changed and has remained the same ever since. Recent versions of Android Studio have dropped support for the pre-2.2 algorithm entirely, so it’s not possible to build apps for Android 1.0–2.1 with the latest IDE (and it keeps adding elements that are too new anyway).

Have you tested compiling an app for 1.0 using Android Studio 4.2.2 (as you suggested) and running it using the official SDK 1.0 emulator? The OpenVK Legacy app uses Android Studio 3.1.2 to develop for <2.2. Unfortunately, I don't have time to test various Studio versions yet, but 2.3.2 totally works for me.

Feel free to join the Retro Android Group to discuss

I only have a 2.1 device and not interested in anything prior, sorry
