Ivan recently had the pleasure of optimizing an app written in Sencha Touch 2.2 that was taking over 5 seconds to load on an Android 2.x device. The culprit was a 1.2 MB app.css file that he managed to bring down to just over 100 kB, resolving the issue. In this article, he presents four techniques used to achieve this goal, along with individual outcome metrics.
In Part 1 and Part 2 of our series on Developing Mobile Applications with Force.com and Sencha Touch, we built out a simple mobile application hosted in a Salesforce.com Visualforce page to display a list of Leads, and allowing add, edit and delete capability using an Apex controller. In this third part of the series, we want to highlight the enterprise data capability of Sencha Touch, so we’ll focus on how the framework allows us to work with large datasets by adding paging and search capability to the PocketCRM application.
Sencha Cmd 3.0 is the newest addition to the set of tools that make it easy to build Sencha applications. The new Cmd greatly increases the functionality of what you can do on the command line, giving you the ability to scaffold, build and minify projects.
In the final part of our tutorial series on Sencha Touch components, we’ll cover styling for our Ext.tux.AudioCover component. Over the last few posts, we’ve walked through the component’s code development, which you can find posted here and here, but now we want to customize our component’s look.
We’re back with part two of our Sencha Touch 2.1 component creation tutorial. In part one of this tutorial, we introduced the concept of Sencha Touch components, our Ext.tux.AudioCover idea and began defining the functionalities needed for our Ext.tux.AudioCover to be a success. Today, we’ll be continuing with detailing those definitions, starting with the configuration parameters.
We’ve heard developers ask for more tutorials and guides for our frameworks, and today we’re walking through Sencha Touch component creation. I was recently asked to create an HTML5 component that would allow users to hear a preview of an audio track and show its progress inside a circular progress bar, similar to the iOS component.
