Video: Offline Access to Images in Mobile Applications Using SQLite

Building offline appsAlpha Anywhere features extensive capabilities for building mobile applications with offline access. One way to extend the amount of data that can be stored in your offline apps is through the use of a SQLite database.

Using SQLite in a PhoneGap application enables you to store a large amount of information on the device that will still be available even when the device is disconnected from its wireless signal - allowing users to work offline uninterrupted. Often, you may want to include images as part of the data stored in the SQLite database.

In this video we show how you can build a UX component that makes a callback to the Alpha Anywhere server to create a SQLite database of 500 records, with each record having an associated image. The SQLite database is then download to the device and stored on the device. Then, a SQL query is executed against the on-device SQLite database and a List control is populated showing all of the records and their associated image.

The Alpha platform is the only unified mobile and web app development and deployment environment with distinct “no-code” and “low-code” components. Using the Alpha TransForm no-code product, business users and developers can take full advantage of all the capabilities of the smartphone to turn any form into a mobile app in minutes, and power users can add advanced app functionality with Alpha TransForm's built-in programming language. IT developers can use the Alpha Anywhere low-code environment to develop complex web or mobile business apps from scratch, integrate data with existing systems of record and workflows (including data collected via Alpha TransForm), and add additional security or authentication requirements to protect corporate data.
