only way possible would be to get a rooted phone. and install a emulation of Windows. then you could use exe files. then maybe a keyboard app . then your better off using a controller. which will make your player slide from another players game. this method is only good for admins. id explain more but about to clock into work...
Windows emulation on android is extremely slow. Even something as minimal as a compact Windows 98 cannot run at acceptable speeds, let alone XP with GTA 3 installed. It would be extremely choppy, slow, and laggy, and thats if GTA 3 would even start (which I doubt it would since the only decent emulator that runs XP on android is qemu, and it has only like 4 emulated graphics driver choices and they're all crap).
What I think would be the best thing to do would be to get a remote software like TeamViewer onto your PC, download the app on your phone, and connect from there. GTA 3 on Android's code is almost entirely different, and it's going to be even more different because the code that GTA 3 on Android uses was an older build of GTA 3 (not 1.1).
tl;dr It's almost impossible that LU support will come for Android.
