Overview of this book

This book will take you through the process of building cross-platform, native UI applications for the mobile from scratch. You will learn how to develop apps, how to use GPS, cameras and photos and how to build socially connected apps. You will also learn how to package them for submission to the App Store and Google Play. This cookbook takes a pragmatic approach to creating applications in JavaScript from putting together basic UIs, to handling events and implementation of third party services such as Twitter, Facebook and Push notifications. The book shows you how to integrate datasources and server APIs, and how to use local databases. The topics covered will guide you to use Appcelerator Studio tools for all the mobile features such as Geolocation, Accelerometer, animation and more. You’ll also learn about Alloy, the Appcelerator MVC framework for rapid app development, and how to transfer data between applications using URLSchemes, enabling other developers to access and launch specific parts of your app. Finally, you will learn how to register developer accounts and publish your very own applications on the App Store and Google Play.

Creating a SQLite database


There are many reasons SQLite has become the relational database of choice for mobile handsets. It is scalable, fast, written in native C, and very portable, and has the added benefit of an exceptionally small footprint.

Storing data locally and caching remote data can help speed up data access times in our applications. This is particularly important when mobile devices may have limited connectivity and bandwidth.

There are two ways to create and implement SQLite databases in your application: one is by creating the database in code using SQL, and the other is by copying and attaching an existing database to your app via the install method. In this recipe, we'll explain how to create a database via SQL statements.

How to do it...

Create a new JavaScript file called database.js, and type the following code at the top of your new file:

//create an instance of a database
module.exports = (function() {
  //create the database object
  var db = Ti.Database.open('mydb')...
