Not an Android user myself but if you download the Bimmercode app (free demo mode) it lists the various adapters supported for models with links to suppliers. Obviously your call, but I doubt the amount of mods you can do (exc. the Start/Stop) on a 128ti would be worth the outlay, unless you were going to use it frequently on other cars. Bimmercode and a suitable adaptor will probably set you back £80-£100 so you may be better off finding someone to do whatever mods you want for the price of a couple of beers.
