Are you a developer? No? Then why are you reading this? This is developer stuff. Heck, I really don't know why I'm writing it, I'm not a developer. I don't even have a beard.
But anyway, if you are an Android app developer, Chainfire has come up with a tool that should make your life slightly easier. Ever notice that even when making a minor change to your app in Eclipse that it takes forfreakingever to build the updated apk file? We're talking 30-35 seconds. Which, to be fair, is basically an hour in internet cat video time.
Chainfire got tired of this problem, and decided to fix it. He hasn't explained how, exactly, but he noticed the problem was centered around AAPT (Android Asset Packaging Tool) and the way it handles XML files, and started tinkering around with the source code. The result? FAAPT. Keep your mind out of the gutter for a second while I tell you what it does. It packages your apps faster! Way faster. Like, in 2-3 seconds. That's fast. Chainfire says he's working on getting his fixed tool submitted to Google as a patch, but it still needs work before it'll be approval-ready.
In the meantime, you can download it at XDA. Happy FAAPting!
