This is the second in a series of blog posts by Kevin Long, Janrain Technical Product Manager, to introduce the new Janrain Engage Social Login Widget and provide detail on how to use the new enhancements. Read other posts within the Janrain Technical series.
We’re pleased with the response to our advanced Janrain Engage Social Login Widget and the excitement its generating. Last time we covered the new style and layout features. This time we will focus on Mobile support. Please stay tuned for future posts on:
Janrain products have features to help you support users of mobile devices. These features are automatically used by the widget when they are enabled on the mobile device.
One Size Does Not Fit All!
Screen Resolution on mobile devices varies wildly. While almost all have greater than the 160 pixel width of the first generation and most current devices are in the 320-480 pixel width range, tablets and newer high density displays bring new dimensions and unheard of DPIs that complicate the rendering of usable content.
A Touching Gesture
Touch screen devices enable a new mode of interaction called gestures.
These are primarily used to perform navigation tasks. There is not a consensus on which gestures represent which actions. There is also no universal agreement yet on browser event models.
What’s your Angle?
Mobile devices can be tilted and used in both horizontal/landscape mode and vertical/portrait mode. Users expect web apps to detect and resize and re-layout content dynamically based on each change in of orientation.
Now lets take a look at the features in the new Janrain Social Login Widget that address these needs.
Mobile Web Browsers now include many features that are specific to the needs of mobile. There are a few core features that are well supported by most mobile web browsers and are applicable to authenticating on the mobile web.
Zooming may be triggered by double tapping or unpinching depending on your browser/device.
Tilting/rotating your device will automatically triggered a horizontal layout on most devices.
Swipe gestures are the touch equivalent of scroll bars or classic page-up/page-down keys.
Janrain Engage can be configured to display more than one page of login buttons to reduce the cluttered “nascar effect” of having too many logos while still providing a variety of options to support a diverse population.
Swipe is automatically enabled by Janrain when available on the device. Swipe by touching and dragging to reveal additional providers.
Sometimes mobile applications need a tighter integration than can be provided through a pure web based application. Native applications can perform better, feel more familiar and may have access to device features that are not available from the web browser sandbox.
This new web widget functionality is made available in addition to the Native Mobile App development for social login and sharing we provide both a Library for Apple’s iOS and for Library for Google’s Android native development platforms.
These features are all applied automatically if the user has the features available on their mobile browser and device and have them enabled in their settings.
Here are some links to device settings information and alternative mobile browsers that may provide more support than the stock browser that shipped with your device.
