DroidAssets allows you to generate all the assets you need for your Android application in record time. Drag-and-drop an asset from the res/drawable-{density} folder, and this asset will be generated for all the other densities you need. This works not only for simple PNG's, but also 9-patches.

• Resize PNG assets
• Regenerate 9-patches for reduced images
• Place the generated images in the right drawable folder

Version 1.1.0:

• Fix 9-patch for images 1px wide that could be cut in some cases
• Fix vertical 9-patch that was reversed
• Fix 9-patch that could extend in the corners sometimes

Requirements

• OS X 10.8 or later
