Shadow4Android

Shadow4Android is a Lightweight browser utility AImed at Android developers who need drop shadows in their APP layouts. Instead of hand-drawing a 9-patch asset and carefully DeFining its stretchable regions, you configure the shadow visually and let the page produce the drawable file for you.

What it does

The tool focuses on one nARRow job: creating shadow images in the Android 9-patch format, which uses black markers on the outer edge of a bitmap to tell the platform which rows and columns may be stretched. Because shadows box-shadow-style effects are not natively simple to reproduce through Standard Android shape drawables, a generated 9-patch remains a prACTical approach for cards, buttons, and floating panels. The interface exposes shadow controls, and the resulting asset can be dropped into a project's drawable folder.

Key capabilities

• Visual configuration of shadow appearance, with options that the page describes as fully customizable.
• OuTPUt in the 9-patch image format, ready for use as a background drawable.
• Runs entirely in the browser, so there is nothing to install.
• Useful for producing repeatable shadow assets across different densities and component sizes.

Who it is for

This utility suits Android app developers and UI engineers who want consistent elevation-style shadows without writing custom drawing code. designers who hand off assets to engineering teams may also find it handy for prototyping the look of a card or dialog background. It is a small, single-purpose tool rather than a full design suite, so teams working across iOS or web will still need other resources.

How to get started

1. Open the tool in a desktop browser.
2. Adjust the shadow settings until the preview matches your intended design.
3. Download the generated 9-patch image.
4. Place it in the appropriate drawable resource folder and reference it as a background in your layout XML.

Because 9-patch files rely on precise marker pixels, review the exported asset in an editor or the Android Studio preview to confirm the stretch regions behave as expected. Scaling or recompressing the file can damage those markers.

Pricing and access

The page appears to be a free, open web utility with no account requirement; pricing, hosting longevity, and browser compatibility may vary and should be verified before relying on it in a production pipeline. As with any third-party generator, check that exported assets meet your project's licensing and quality standards.
