Selendroid, работающий со Skype apk; не с другими приложениями

Нужна ваша помощь с selendroid. Я новичок в этом и все еще учусь трюкам.

Пробовал с базовым примером приложения selendroid и с Skype apk, все работало отлично. Однако при попытке использовать apk других приложений, таких как tripadvisor и dropbox, я продолжаю получать сообщение об ошибке.

Ниже приведен мой код и ошибка из консоли. Я использую сведения о версии из манифеста xml.

Дальнейшее исследование. Я сравнил xml-файл манифеста Skype, Dropbox и т. д. и увидел тег разрешения с уровнем защиты "Подпись" для Dropbox, tripadvisor. Однако этого нет в файле манифеста скайпа. Может ли это мешать нашему коду.

Если да, то есть ли обходной путь?

Любая помощь в этом очень ценится.

    SelendroidCapabilities caps = new SelendroidCapabilities("com.dropbox.android:2.3.8") ;
    System.out.println("I am here");
    caps.setPlatformVersion(DeviceTargetPlatform.ANDROID19);
    System.out.println("I just reached here");
    caps.setEmulator(true);
    System.out.println("Passed emulator");
    //caps.setCapability(CapabilityType.BROWSER_NAME, "Android");
    //caps.setCapability("app-package", "com.tripadvisor.tripadvisor:8.7.1-release");

    try {
        System.out.println("Let me try");
        driver = new SelendroidDriver(new URL("http://localhost:4444/wd/hub"), caps);
        System.out.println("Driver ...");
        driver.switchTo().window("NATIVE_APP");
        System.out.print("Got the app");
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }  

}
}
