你试过这个吗

这意味着这不是主要目的的活动，请检查您的

清单

了解实际的启动程序活动我如何检查清单我刚刚有了apk，如果您没有代码访问权限，请询问启动程序活动是什么

public class Jodel {


    private static AndroidDriver driver;
    public static void main(String[] args) throws MalformedURLException {
        // TODO Auto-generated method stub



        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
        capabilities.setCapability("deviceName", "Moto G(3rd Generation)");
        capabilities.setCapability("platformVersion", "5.1.1");
        capabilities.setCapability("platformName", "Android");
        // capabilities.setCapability("app", app.getAbsolutePath());
        capabilities.setCapability("appPackage",
                "com.tellm.android.app");
        capabilities.setCapability("appActivity",
                "com.jodelapp.jodelandroidv3.view.mainactivity");
    capabilities.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT,"100");

        driver = new AndroidDriver(new URL("http://0.0.0.0:4723/wd/hub"),
                capabilities);
    }

}
