Encountered internal error running command: Error: Error occured while starting App

Question

The problem: My app opens up and shuts off before ScrollTo() command execution.

I got this error on Appium:

'Encountered internal error running command: Error: Error occured while starting App. Original error: com.disney.wdpro.android.mdx.activities.LoaderActivity or com.disney.mdx.wdw.google.com.disney.wdpro.android.mdx.activities.LoaderActivity never started'

Appium logs:

    File app = new File(appDir, "com.disney.mdx.wdw.google.apk");

    DesiredCapabilities cap = new DesiredCapabilities();
    cap.setCapability(MobileCapabilityType.PLATFORM_NAME, 
    MobilePlatform.ANDROID);
    cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Android Device");
    cap.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, "50");
    cap.setCapability(MobileCapabilityType.APP, app.getAbsolutePath());

    AndroidDriver driver = new AndroidDriver(new 
    URL("http://169.254.159.242:4723/wd/hub"), cap);
    driver.scrollTo("Get Started");
    TouchActions t = new TouchActions(driver);
    WebElement abc = 
    driver.findElementById("com.disney.mdx.wdw.google:id/tutorial_button");
    t.singleTap(abc).perform();

Along with the desired capabilities, we need to pass the "appPackage" and "appActivity". Below are the complete desired activities that i have used in my project.

        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName","ANDROID");
        capabilities.setCapability("platformVersion", "5.1");
        capabilities.setCapability("platformName",Constant.appPlatform);
        capabilities.setCapability("app", app.getAbsolutePath());
        capabilities.setCapability("appPackage", Constant.appPackage);
        capabilities.setCapability("appActivity",Constant.appActivity);

You can get the details of the appPackage and appActivity from developer or http://toolsqa.com/mobile-automation/appium/how-to-find-apppackage-and-appactivity-for-apk-file/

Hope this helps you. Thanks.
