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.
Android Studio is just a specialised IntelliJ IDEA, so you can use its Shelve Changes functionality. Go to the Version Control tool window in AS, right click the changelist and select Shelve Changes.... Then do your build without your local changes and unshelve the changes afterwards.
