1、SDK、adb、fastboot隨著版本迭代都有了一點變化，編譯以Android6.0為界

2、權威參考sdk/docs/howto_build_SDK.txt

3、adb windows版編譯方法：

make host_cross_adb

4、fastboot Windows版編譯方法：

make host_cross_fastboot

5、Android7.0編譯Android使用的adb

6、Android adb的system許可權使用者無法獲取usb裝置

修改system/core/./rootdir/ueventd.rc,加入

/dev/bus/usb/*/*            0777    root        usb
