Single-purpose Hybrid Apps launch automatically when the device user opens the Hybrid Web Container.
To make an application single-purpose, you must set it as the default for the device. If the device has only one assigned Hybrid App, but you do not set it as the default, the user must navigate through the Hybrid Web Container and select the Hybrid App.
Once you have set a default, you can still assign other Hybrid Apps to the device, but only the default application is active.
You can change the default application at any time if you want the user to see a different application when the Hybrid Web Container is launched. For example, for an application that shows coupons or deals, you can update the deals each week and assign a new application with the updated deals as the default.
