创建基于com.android.support库的uiautomator2.0工程的要点

1、新建工程的时候，要勾选此项

2、build.gradle(:app)文件中添加依赖

androidTestImplementation 'com.android.support.test.uiautomator:uiautomator-v18:2.1.3'

//    指定java编译版本
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

3、AndroidManifest.xml中申请需要的权限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<!--//发送inputkeyevent权限-->
<uses-permission android:name="android.permission.INJECT_EVENT" />

 4、示例化UiDevice对象

UiDevice mDevice = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
