Marat Fayzullin has ported his (commercial) GameBoy Advance emulator VGBA to the Android platform: VGBA for Android

Quote:
New in 3.6.13:
  • Added support for ZIP files.
  • Added ability to open files with my other emulators (i.e. VGB, iNES, etc).
  • Made corner buttons thinner to avoid overlaps.
  • Added configurable fast-forward button.
  • Made screenshot sizes uniform.
