Gradle build errors in Android Studio: Content is not allowed in prolog

I imported the latest version of the Parse library for setting up Push Notifications today and I'm getting a new Gradle build error after doing so. I've done some initial searches and from what I'm gathering, this can be caused from invalid XML files, which is all well and fine, but it's indicating one of the drawable (PNG) resources is causing the issue. I've tried to just remove the drawable from the project just to see if it'd move on, but the next resource triggers the same error ad-infinum. Any insight where to look for resolution would be appreciated!

I got a stack trace of the error from Gradle. I'm not sure of what I'm reading here, truth be told. Also, to provide more information: I've attempted to restore the previous Parse library (1.6.0) and still get the same error, I've done a clean rebuild, and I've also Invalidated the Cache in Android Studio and restarted, still seeing the same error!

Found the answer. I only found the solution after looking at the files in Explorer instead of Android Studio. Windows had encrypted the files for some reason or another. Once I turned off file encryption they were able to be included and the build completed fine.
