The ProGuard tool shrinks, optimizes, and obfuscates your code by removing unused code and renaming classes, fields, and methods with semantically obscure names. The result is a smaller sized .apk file that is more difficult to reverse engineer. Because ProGuard makes your application harder to reverse engineer, it is important that you use it when your application utilizes features that are sensitive to security like when you are Licensing Your Applications.

You should enable proguard in release mode. Check the link below under the topic Enabling Proguard

http://developer.android.com/tools/help/proguard.html

Example:

To enable proguard commemt the line below this line in your project.properties file

To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
