From Haiyu Dongxiang:
Droid4X is an ideal simulator of the original Android system. After downloading the Droid4X, PC users may have a virtual Android handset with individualized configuration and performance (subject to the PC’s configuration & performance). The user may use the simulator to download the Android apps and games, and run/play them on a PC screen in a more convenientmanner than the handset. Droid4X includes the Windows version and Mac version, and the iOS version is under development.
