So I downloaded a template from http://www.androidbootstrap.com/ and I was able to compile and deploy it after changing a few things. However, there are errors in every java and layout file. All of the libraries are showing up with red underlines in the imports section and all of their functions are doing the same. It's not able to find the functions when I'm editing, but when building it seems to be fine. What can I do to fix this?

Caches files must be corrupted.

Go to menu File and select Invalidate Caches / Restart

None of these solutions helped me solve my problem. I ended up creating a new project and giving up on Android Bootstrap because I could never get it to work. Things I do now to ensure gradle behaves well:

  1. Updated Android Studio via the help menu. The latest version downloaded from Google was actually 0.4.2, and I was able to upgrade to 0.4.4.
  2. Created a new project, without much fluff.
  3. Made sure I could build the project and deploy.
  4. When I added libraries, such as androidannotations, I added them to the second level gradle.build file and then immediately went to tools-->refresh project from gradle. Then I made sure the project built. This is important because your project won't import the library until you refresh the project from gradle.

Hopefully this helps some people who are getting into gradle development.

I had a similar problem. In my case the solution was that I had to add maven { url 'https://jitpack.io' } in settings.gradle.

I don't use Android Studio, so I can't say for sure. However, I do use its cousin IntelliJ. It sounds like Studio doesn't know about your Gradle build file. In IntelliJ, the Gradle plugin needs to be installed, and you need to add the build file to the project (or create a new project from an existing file). I would think those would be automatic in Studio. Regardless, try to see if something comparable applies for you.
