如何从主页启动appium中的应用程序

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.remote.MobileCapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;

public class AppiumExample {
    public static void main(String[] args) {
        // 设置Desired Capabilities
        DesiredCapabilities desiredCapabilities = new DesiredCapabilities();
        desiredCapabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
        desiredCapabilities.setCapability(MobileCapabilityType.DEVICE_NAME, "device_name");
        desiredCapabilities.setCapability(MobileCapabilityType.APP_PACKAGE, "com.example.myapp");
        desiredCapabilities.setCapability(MobileCapabilityType.APP_ACTIVITY, ".MainActivity");

        // 初始化Appium客户端
        AppiumDriver<MobileElement> driver = new AndroidDriver<>("http://127.0.0.1:4723/wd/hub", desiredCapabilities);

        // 启动应用程序
        driver.launchApp();

        // 等待应用程序启动
        // 这里可以添加一些逻辑，如等待某个元素可见，确保应用程序完全启动后再执行后续操作

        // 其他操作...
    }
}
