Android Uiautomator创建过程

网页上看到uiautomator的简单例子，想尝试执行，无奈太菜，不晓得如何由工程创建jar文件，网上搜索一番找到了详细说明，在此记一笔，加强印象。

1.使用Eclipse，需要先创建一个java项目New-Java Project----命名为Uia

2.右击项目工程--Build Path--Configure Build Path--在Libraries一栏Add Library->Junit；然后Add External JARs-->Android SDK目录下platforms/android-*/android.jar和uiautomator.jar

3.新建测试case，加一个官网的样本case（转自：http://developer.android.com/tools/testing/testing_ui.html）

package com.uia.example.my;// Import the uiautomator librariesimport com.android.uiautomator.core.UiObject;import com.android.uiautomator.core.UiObjectNotFoundException;import com.android.uiautomator.core.UiScrollable;import com.android.uiautomator.core.UiSelector;import com.android.uiautomator.testrunner.UiAutomatorTestCase;public class LaunchSettings extends UiAutomatorTestCase {      public void testDemo() throws UiObjectNotFoundException {               // Simulate a short press on the HOME button.      getUiDevice().pressHome();            // We’re now in the home screen. Next, we want to simulate       // a user bringing up the All Apps screen.      // If you use the uiautomatorviewer tool to capture a snapshot       // of the Home screen, notice that the All Apps button’s       // content-description property has the value “Apps”.  We can       // use this property to create a UiSelector to find the button.       UiObject allAppsButton = new UiObject(new UiSelector()         .description("Apps"));            // Simulate a click to bring up the All Apps screen.      allAppsButton.clickAndWaitForNewWindow();            // In the All Apps screen, the Settings app is located in       // the Apps tab. To simulate the user bringing up the Apps tab,      // we create a UiSelector to find a tab with the text       // label “Apps”.      UiObject appsTab = new UiObject(new UiSelector()         .text("Apps"));            // Simulate a click to enter the Apps tab.      appsTab.click();      // Next, in the apps tabs, we can simulate a user swiping until      // they come to the Settings app icon.  Since the container view       // is scrollable, we can use a UiScrollable object.      UiScrollable appViews = new UiScrollable(new UiSelector()         .scrollable(true));            // Set the swiping mode to horizontal (the default is vertical)      appViews.setAsHorizontalList();            // Create a UiSelector to find the Settings app and simulate            // a user click to launch the app.       UiObject settingsApp = appViews.getChildByText(new UiSelector()         .className(android.widget.TextView.class.getName()),          "Settings");      settingsApp.clickAndWaitForNewWindow();            // Validate that the package name is the expected one      UiObject settingsValidation = new UiObject(new UiSelector()         .packageName("com.android.settings"));      assertTrue("Unable to detect Settings",          settingsValidation.exists());     }   }

4.保存case，打包成jar

<android-sdk>/tools/android create uitest-project -n <name> -t 1 -p<path>

name是项目名称，也就是Uia；-t参数后面数字指的是target的id，可以用“android list”命令查看对应id；path是项目所在路径。执行此命令之后，会在项目文件夹里生成3个文件：build.xml、local.properties、project.properties。Eclipse中右击build.xml文件Run as-Ant Build，成功的话会提示BUILD SUCCESSFUL，打开build.xml，将default="help"更改为【default="build"】，再次Run as Ant Build。会在项目目录bin文件夹下生成Uia.jar。

5.Push jar并执行

Push到手机：adb push [path]\Uia.jar /data/local/tmp/

执行case：adb shell uiautomator runtest Uia.jar -c [case所在包.名称]
