ubuntu下执行cts

某日需要在Ubuntu下执行cts，却发现设备不能被adb访问如下：

$ adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
????????????    no permissions

首先识别设备：

step 1：得到设备ID,注意某一厂商所有产品的idVendor应当固定不变，只是具体产品idProduct不一致

$:lsusb

Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 004: ID 413c:2010 Dell Computer Corp. 
Bus 004 Device 003: ID 0461:4d15 Primax Electronics, Ltd Dell Optical Mouse
Bus 004 Device 002: ID 413c:1003 Dell Computer Corp. Keyboard Hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 065: ID 22b8:433b Motorola PCS 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

得到设备idVendor=22b8 idProduct=433b.

step 2: 设置udev设备权限

sudo vim /etc/udev/rules.d/51-android.rules

# adb protocol on passion (Nexus One)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e12", MODE="0600", OWNER="user"
# fastboot protocol on passion (Nexus One)
SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", ATTR{idProduct}=="0fff", MODE="0600", OWNER="user"
# adb protocol on crespo (Nexus S)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e22", MODE="0600", OWNER="user"
# fastboot protocol on crespo (Nexus S)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e20", MODE="0600", OWNER="user"
# product phone
SUBSYSTEM=="usb", ATTR{"myphone"}=="22b8", ATTR{idProduct}=="433b", MODE="0600", OWNER="user"

完成后，注意要先拔掉设备再次插入即可访问如下：

$ adb devices
List of devices attached
0A3BB6731201101B    device

运行CTS:

step 1:生成cts zip文件android-cts.zip

make cts

step 2:运行

unzip android-cts.zip

android-cts/tools/startcts
