Update – 12/18/13 - As part of our continuing efforts to simplify the Amazon Appstore for developers we have loosened the requirement for SSL in Web Apps.  The practice is still recommended but not required to pass certification for certain scenarios such as Geolocation and Authentication.  You can view additional details on using SSL in your Web App here.

Following up on the latest in a series of webinars covering Amazon devices, game services, and mobile applications, here’s a list of questions we collected during and after our presentation on HTML5 Mobile Web Apps.

Q: How much does it cost to publish my Web Apps?
A: There are no developer registration or subscription fees. There is no cost to publish your Mobile Web Apps with Amazon and all of the corresponding services, such as In-App Purchasing, are free to use.

Q: How are apps currently published, do I need to have a Website?
A: Currently Web Apps get distributed by having you host all of your current on your own Web Infrastructure. You are free to use any hosting service and we walk through an AWS EC2 Micro Instance in the recorded webinar.

Q: Do I need to make any changes to my Website?
A: We support HTML5 and responsive web design for all Web Apps. The only required change is that you create a web-app-manifest.json file and return the JSON correctly. This ensures you are the owner of the website. We also highly encourage the use of SSL.

Q: How do I test my Web App?
A: Since the Web App application is the same HTML5 code as your Mobile Web site you can do all of your testing through a browser like you would normally or your favorite Developer IDE (WebStorm, Eclipse, Sublime, Visual Studio, etc.)

Q: How do I test my Web App on a Kindle Fire or Android Device?
When you are ready to see the website running on a device you can install the Web App Tester from the Amazon Appstore. The Amazon Web App tester will run on Kindle Fire and select Android devices.

Q: How do I debug my Web App on a device?
A: The Web App Tester tool uses ADB to allow debugging of your Web App through the Chrome Dev Tools. We do a complete walk through of this process in the recorded webinar and you can get more details on our SDK website here.

Q: What HTML5 features are currently supported?
A: The current version of Web Apps is built on the open source Chromium project version 25. You can view the full list of supported features here.

Q: Can I lock the device screen orientation?
A: Yes for a full list of best practices around device orientation and other capabilities check out the SDK documentation here.

Q: How do I take screenshots of my Web App for submission to the Appstore?
A: You will need to run the Web App Tester on a Kindle Fire device and hold down the power button + volume down. Once you have taken the screenshot you can find it in your pictures\screenshots folder. You can read more details here and we walk through this process in the recorded webinar.

Q: Where can I find the current version of the Amazon Web App API JavaScript file?
A: The current Web App API library is hosted here and available for viewing or inclusion in your own web projects. The recorded webinar includes a walkthrough and summary of this file.

Q: Can I use In-App Purchasing with my Web App?
A: Yes, you can choose to implement your own In-App Purchasing or you can take advantage of the Amazon In-App Purchasing API for JavaScript. We walk through setting up the IAP API for JavaScript in the recorded webinar.

Q: Are Web Apps eligible for the Amazon Developer Select program?
A: Yes, Web Apps are eligible for Amazon Developer Select and you will automatically see the status for each of your apps under the My Apps section in the developer portal.
