I use SVN in Android Studio which tracks the changes I've made compared to the committed copy. Today, I wanted to build an APK for QA without incorporating the changes I've made to some classes that I hadn't committed yet to SVN. Is there a way to make an APK that would ignore the changes or do I have to comment each of the lines I've added/changed out (which is what I did today but seems like there would be a better solution)?
Edit: I forgot to include that I was looking for a way without having to create a separate branch. Vampire's solution is perfect.
