This tutorial introduces the MoSync API for User Interfaces (MAUI). It describes how to use the MAUI library classes to build screens and widgets and how to extend the MAUI model with your own custom components.

This tutorial gives you a short introduction to developing mobile applications with MoSync. If you’ve never created a mobile application with MoSync before, this is a great place to start. In this tutorial, we’re going to create a new project in Eclipse, create a new screen, and interact with the user.

Mobile offers developers a new world, with cool devices and nice, easy, small projects compared to that monstrous and boring enterprise code you've been doing in Java or C#, right? Right! However, there are somethings I'm going to tell you to help you move your Java/C# skill to C++ in MoSync. The reality is that both Java and C# are based on syntax from C, so you are going to be able to read C++ source code without anyone having to explain how curly braces work or reminding you to put a semi-colon at the end of the line, which is cool.

In addition to the standard methods of downloading data using the Connection, HttpConnection, or Downloader objects, the MoSync SDK provides a special downloader, the AudioDownloader class, for retrieving audio files from the Internet. The AudioDownloader is a useful wrapper for the Downloader class and is specifically for audio files.

In our Discovering Devices and Services with Bluetooth tutorial we demonstrated how the MAUtil::BluetoothDiscoverer class can be used to locate nearby devices and find out which Bluetooth services they support. Once you’ve discovered a device and a service you will need to write a client for that service and open a data connection to the server. That's what we will be doing in this tutorial.

Implementing Bluetooth in your application is usually done in three stages. Firstly, there is device discovery: getting the phone to scan for other devices in range. Secondly, there is a service discovery: querying a discovered device to see which protocols and services it supports. Lastly, there is the implementation of a service, a specific transfer of data. This tutorial covers the first two steps: discovering devices and services.

There are obvious occasions when you want do download data from the Internet for your games or application.  There are even obvious occasions when you want to download images and sounds using the ImageDownloader and AudioDownloader.  What might appear less obvious is the use of a Custom Downloader.
