Question

无法启动应用程序，请查找以下相同的跟踪

注意：同样的应用程序与卡拉巴赫工作，即我能够启动应用程序

我正在使用以下功能：

public class BaseAppiumTest 
{
    AndroidDriver driver;

    @Before
    public void setAppium() throws MalformedURLException {
        File classpathRoot = new File(System.getProperty("user.dir"));
        File appDir = new File(classpathRoot, "/apps/");
        File app = new File(appDir, "automation_test_artifact.apk");
        AppiumUtils appium = new AppiumUtils();
        appium.devicename = "Android Emulator";
        appium.app=app.getAbsolutePath();
        appium.appPackage="com.morrisons.instore.sit";
        appium.appActivity=".HomeActivity";
        appium.platformVersion="4.4";

        DesiredCapabilities capabilities = appium.getCapabilities();
        driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
    }

    @After
    public void teardown()
    {
        driver.quit();
    }
}

尝试找出您试图运行的应用程序的可启动活动名称。有时，AndroidManifest.xml文件中可能没有给出可启动活动名称。您可以使用以下命令来验证是否存在可启动活动名称：

aapt dump badging <path-to-apk> | grep launchable-activity:\ name
