Xendroid has testing build for controllers, works great like x360.
I feel like Xendroid has better performance once shaders build compared to x360 with 4 player campaign co-op. Using my konkr pocket fit elite for player 1 and 3 ps4 controollers, vibration works too for them.
Here is the testing build for multiple controller support.

Here is the mod for halo 3 - 4 player campaign co-op. (only the files, not the actual game)
many other games work great too with multiple controllers. Very nice for a portable gaming night. only if the device is strong enough and has the battery for it >.<
ashnar and rfandango been doing great with the emulators.
