appium界面运行过程：
1、启动一个http服务器：127.0.0.1:4723
2、根据测试代码setUp()进行初始化，在http服务器上建立一个session对象
3、开始调用adb，找到连接上的设备，设置设备id
4、等待设备准备好响应命令
5、开启logcat日志监控
6、将生成的apk属性信息文件strings.json存到了设备 /data/local/tmp目录下
7、读取apk安装情况
8、端口映射，发给appium httpserver的内容，经过httpserver后直接发给设备
forward tcp:4724 tcp:4724
9、将AppiumBootstrap.jar包存到设备的 /data/local/tmp目录下
10、安装UnicodeIME-debug.apk到设备上
11、安装settings_apk-debug.apk到设备上
12、安装unlock_apk-debug.apk到设备上
13、 kill所有的uiautomator进程
14、运行bootstrap---uiautomator runtest ***.jar –c ……-e…..
15、在端口4724打开appium socket server
16、加载json,唤醒客户端
17、提交command到appium
18、启动设备，解锁屏幕，准备接收command
19、将响应结果返回给client
20、执行测试代码
21、关闭日志监控
22、关闭客户端链接
23、关闭Uiautomation
24、清理Android对象
25、清理appium session
