Starting today all Web App submissions to the Amazon Appstore now support Amazon Device Targeting. While it is possible to detect and optimize your mobile websites server side, you may decide you only want to target your Web Apps to specific devices. Web App submissions to the Amazon Appstore now allow the same device targeting capabilities that Android submissions do. This means you can elect to make your Web Apps available for download on Kindle Fire, Kindle Fire HD, Kindle Fire HDX, general Android (all non-Amazon) devices or any combination of these.
By enabling device targeting within your individual Web Apps you can tailor your app experience to the specific screen size, density, and capabilities of Kindle devices. For example, you may decide to target only devices capable of the Amazon Webview (Kindle Fire 2nd generation and up) giving your Web Apps native-like speeds on Kindle devices.
What has changed?
In the previous version of the developer portal you did not have the option of choosing the device on which devices your Web Apps would be available. By default your Web Apps would run on all Kindle Fire devices as well as Android capable devices.
As of today, a new Device Support section has been added that will allow you to target any or all of Web App capable devices you choose.
Enabling Device Targeting
To enable Device Targeting in your Web Apps simply navigate to the Apps and Services, My Apps section in the developer portal, click on the title of your Web App, and then select the App File(s) tab.
You can then select the individual devices you want to target. By default we will enable all Web App capable devices so be sure to uncheck any devices you specifically do not want to support. Once you click the Save button you will find a new list of all the devices you have selected to support.
That’s it! By following these few steps you now have more control over which devices your Web Apps will run on, giving you the option to tailor your app experience to the capabilities of each device.
