Hmm, no idea about running it on an emulator, probably best to run the Windows version if you're on PC anyway.
About the Android version... well, it runs OK on a 2017 mid-range phone. Depending on your phone model, it may actually run fine. However, I strongly suggest playing the Windows version if you want to challenge the songs on hard difficulty!
