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 libraries
import 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]
