Pirated Android apps are a large and growing problem. Fortunately, developers can help prevent others from stealing their code with an obfuscation tool like ProGuard. ProGuard makes it much more difficult to reverse engineer Java-based apps, and now it’s built-in to the Android plug-in for Eclipse.
The benefit for obfuscating paid apps is clear, but free apps can also benefit from the technique. It helps protect your income from ad-supported content, and if your app is a game, it can help preventing cheating as well.
