The best keyboard for Android compatibility is the BK810.
Because, it pairs with up to 3 devices (F1,F2,F3 toggle) and all the special keys work on Android devices. It also has adjustable back lighting.
The disadvantage is size. It is slightly larger than Apple wireless keyboard.
If you want a small keyboard, most are made with Apple keyboard layout so you have to re-learn the special key layout for Android. Some small keyboards are missing the tab key, which I would not buy. Some of the small keyboards can be used as cover for the Nexus 7 but I prefer my own cover, so I would not buy.
Even though the BK810 is most compatible with Android I have found, the keyboard I actually carry with me and use most is by Anker
. This keyboard is very slim 5mm and slightly larger than Nexus 7.
Most of the special keys on the Anker are not compatible with Android but I do not care because I want fast typing. The layout is large enough to type fast. Also, I have to re-pair the BT almost every time I use it with Android but that only takes a second. The battery lasts weeks easy to recharge. The layout is Apple style and there is a tab key. Since it is smallest it slips in my laptop bag easiest.
If there was an Android version of the Anker, and with tab key, it would be optimal. But, I have not found any.
