Autodesk is a major developer of 2D and 3D design software for use in such areas as manufacturing, construction and engineering. The company has also created a very popular drawing app for iOS called SketchBook Mobile, and the utility has reached 2.2 million downloads since its release about a year ago.

Because of Android’s continuous success, Autodesk has now launched SketchBook for our mobile OS of choice as well. Autodesk calls SketchBook “a professional-grade paint and drawing application,” and it offers a wide range of sketching tools via a convenient user interface. I’ve tested the app for a little while, and the app indeed gives a professional impression.

There are two versions available: SketchBook Express that is free, and SketchBook Mobile for $0.99. Features in the full version include:

• Canvas size 1024×768
• 47 Preset brushes
• Smooth Brush stroking
• Customizable brush settings
• 6 Layers
• Full layer controls
• Move, rotate and scale any layer
• Import photos
• Color Wheel and customizable color swatches
• Dynamic symmetric drawing
• Export images
• Save JPEG, PNG or layered PSD files

According to the Market description, a multi-touch device running Android 2.1 or above is required, and a 1GHz processor and 512MB RAM is recommended. Follow one of the links below if you want to give SketchBook a try.

Synchronizing your music library between phone and computer typically means plugging in your Android phone, mounting into Disk Mode, and drag-and-dropping files to a folder or trying to sync a playlist. Two Android media players have updated to eliminate wires when users want to update their music libraries.

WinAmp was first to announce the latest version of its Android app and desktop media player that can be paired to sync files when both devices are on the same Wi-Fi network. WinAmp recently emerged from beta to include wireless sync, SHOUTcast Radio, widget players, iTunes library import, and Mobile Media Library for updating changes made on the phone or desktop. The app is free in the Android Market.

doubleTwist has countered with its own wireless sync solution called AirSync. Much like WinAmp, the latest versions of doubleTwist for Android, doubleTwist AirSync, and the doubleTwist desktop application can work together to wirelessly sync music libraries. AirSync is currently $0.99 and will remain at that price until doubleTwist sells 10,000 copies. At that point, the price will increase to $4.99. The doubleTwist Player app will remain free.
