InstrumentationRegistry API说明

返回类型 API 解释 static Bundle getArguments() 返回instrumentation参数 static Context getContext() 返回instrumentation对应包的Context static Instrumentation getInstrumentation() 返回当前运行的instrumentation static Context getTargetContext() 返回目标应用程序的Context static void registerInstance(Instrumentation instrumentation, Bundle arguments) 记录或者暴漏当前instrumentation运行，存储instrumentation参数

UiDevices新增API

返回类型 API 解释 void dumpWindowHierarchy(OutputStream out) 获取当前页面层级到输出流（OutputStream） java.lang.String executeShellCommand() 执行shell命令使用shell用户身份，并返回字符串的标准输出 UiObject2 findObject(BySelector selector) 返回符合选择条件的第一个对象 UiObject findObject(UiSelector selector) 返回符合选择条件的UiObject List<UiObject2> findObjects(BySelector selector) 返回所有符合选择条件的对象 <R> R wait(SearchCondition<R> condition, long timeout) 等待的条件得到满足

示例代码如下：
