I have been developing API for mobile devices in my current project and really facing challenges for handling below scenarios.

Mobile team is asking to return all data present from backend (sharepoint we use) in one go making API response time taking at least 1 min to swallow the request. The reason why they needed is they wanted to have functionality work in offline mode means there is no network and user can still access data from mobile. We have told them to do some kind of paging functionality but they wanted All data in one go for offline mode meaning API response is SYNC.

Any help or suggestions will be appreciated!!

Great Article!!

Yes this does include most of the artifacts for building API across different devices.

To make small images, and keep them pretty on the many DPI levels out there (and future displays!), SVG isn't a bad option when the context allows. Support is pretty widespread on mobile, and you can provide fallbacks if you need to support the exceptions and the images are crucial (which images should rarely be, for accessibility).
