Therefore, only third-party Rom For example, cyanogen (cm6 or later) or bluez utility on the official Rom. Bluetooth Mouse and keyboard connection.
Here we will only discuss the second method of adding tools on the official Rom. Mobile phone required Root Permission , Or ADP (Android Dev phone), and busybox needs to be installed.
1. FirstDownload Required tools.

2. upgrade to the root permission and mount/system to read/write. The default value is read-only.

# Chmod 777/system/xbin
3. download File To mobile phone
$ ADB push hidd/system/xbin
$ ADB push hcitool/system/xbin
$ ADB push hciconfig/system/xbin
4. If your mobile phone is not ADP, you may not be able to directly access the local device Computer Copy the file to your mobile phone. In this way, you can connect to your mobile phone with a USB cable, copy the above three files to the root directory of the sdcard, and then execute.

9. Now, the apple Bluetooth keyboard is successfully connected. Open arbitraryProgram , Bluetooth Keyboard The hitting key appears in the input column. Tested, Google Chinese Method can also be used normally and candidate words can be selected with a number key.
10. The remaining problem is Apple's Keyboard Multiple Function Key (adjust volume,Screen Brightness) is not available on mobile phones yet. Further research is needed on how to modify these key locations.
