java-Appium startActivity()函数

我是Appium的新手,在我的代码中,我提供了所需的功能,并编写了一个运行良好的测试用例.现在,我想用相同的代码启动另一个App进行第二次测试,该怎么做？
我听说过startActivity(app-package,app Activity),但是它不起作用,它说未为Web Driver定义的startActivity().

public class Calculator {
WebDriver driver;
@BeforeClass
public void setUp() throws MalformedURLException{
//Set up desired capabilities and pass the Android app-activity and app-package to Appium
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.broWSER_NAME, "Android");
capabilities.setCapability(CapabilityType.VERSION, "4.4");
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("deviceName", "14085521650378");
capabilities.setCapability("appPackage", "com.android.calculator2"); // This is package name of your app (you can get it from apk info app)
capabilities.setCapability("appActivity","com.android.calculator2.Calculator");
configurations specified in Desired Capabilities
driver = new RemoteWebDriver(new URL("http://127.0.0.1:9515/wd/hub"), capabilities); 
}
@Test
public void testCal(){
driver.findElement(By.name("2")).click();
driver.findElement(By.name("+")).click();
driver.findElement(By.name("4")).click();
driver.findElement(By.name("=")).click();
}
@Test
public void Test2() {   driver.startActivity("appPackage", "com.tttk.apc","appActivity","com.tttk.apc.DWDemoActivity");
        for(int i=0; i<20;i++)
        driver.findElement(By.className("android.widget.ImageButton")).click();
}
@AfterClass
public void teardown(){
//close the app
driver.quit();
}}

解决方法:

似乎您正在尝试将该方法与WebDriver实例一起使用.

startActivity方法由仅由AndroidDriver实现的StartsActivity接口提供.因此,理想情况下,它将起作用：

((AndroidDriver) driver).startActivity(<appPackage>, <appActivity>);
