Find/Replace broke my application (reckless mistake)

Question

Out of patience I did one of the things that you're not supposed to do unless you are ABSOLUTELY SURE. I wasn't absolutely sure and now I'm paying for it.

What Happened

My outdated app is using fill_parent as an attribute for android:layout_height. fill_parent is deprecated so I'm switching everything to match_parent. You can probably guess what happened next...

I was wreckless with the Android Studio find & replace tool. Wreckless "undo" is limited. To make it worse I did another find & replace to reverse the situation so here is what is going on:

The Problem

error: cannot find symbol variable fill_parent

I replaced fill_parent with match_parent and by doubling back and replacing match_parent with fill_parent I've ended up replacing much needed deep-level references of to the point where fill_parent isn't even recognized anymore. Worst case I will make a copy of where I'm at, grab the previous version in the repo, and figure out what all changed. Is there a less time-consuming way to do this or am I stuck?

Answer 1

I have all the Apple products because we work with them most but I love the competition Google / Samsung / Microsoft bring and collectively I like the competition better. That being said, Apple saved the day on this one.

auto backup was 10 minutes before the "mishap"

If you're not familiar, Time Machine is a product that Apple created to combat issues like the one I ran into today. Most consumers don't have the know-how of GIT / SVN so when they delete files they are permanently gone unless they have luck with a drive deep scan. Time Machine is a good project and if you use OS X then I strongly suggest you purchase and external drive and make it a Time Machine backup.
