I downloaded the eclipse from the google bundle but yet I dont know if it is optimizing the code once it gets compiled. How do I enable optimiziation and obfuscation for my code in eclipse for java or do I need to get a special plugin to do so? I want to make my files as small as they can to be a quicker download for users If this is a bad question please do not -rep me, just tell me and I'll remove it
I've used ProGuard once or twice, never extensively but my understanding is this: it is an external bundle of files that you must run (either command line or through its GUI) in order to use it. I have used the GUI and it gives you several different tabs for each of the options (Optimizing, Shrinking, and Obfuscation). You can find their project page here with more information and detail on how to use it. As far as I know there is no IDE intergration for ProGuard.
