Build me an Android app that can run old J2ME Java games on modern phones.

I want it to let me load a game, play it with a virtual on screen keyboard, and adjust settings for each game separately. It should handle both 2D and 3D games, including ones that use Mascot Capsule 3D, and it should have scaling so games can fit different screen sizes better. Make it feel like a real emulator app, with a simple library view for installed games, easy launch controls, and options that help with compatibility and performance.

Keep it working on older Android versions too, starting from Android 4.0 if possible. If you need to check current docs or libraries, look them up online and use the best approach.
