光感和接近感应驱动以及测试程序，基于linux2.6.27+imx27,在android底下测试成功。-Light perception and proximity sensor-driven and test procedures, based on linux2.6.27+ imx27, under the test is successful in the android.

锁屏后，根据光感的强度，自动点亮屏幕。用于日常生活中，将手机放在桌面上，不需要两只手就可以查看手机状态的情况。-After the lock screen, according to the intensity of light perception, automatically light up the screen. Used in everyday life, the phone on the table, no hands on the phone you can view the st

Android学习到了后面必然要涉及到传感器，因为传感器能将我们的现实世界的感知和代码链接起来，让我们的程序变得更加接近生活，更有实用价值-Android is bound to learn to relate back to the sensor, the sensor can because our perception of the real world and link the code, Check it out!

基于Androidstudio平台，Java语言实现的用手机蓝牙感知距离的APP代码(APP code based on the Androidstudio platform and the Bluetooth perception distance implemented by the Java language)
