Android Studio cannot find symbol error

I'm sorry if this is a noob question but I have recently moved from Eclipse to Android Studio and have never used Gradle before. I have imported one project from eclipse which depends on 3 libraries (UIL,androidBootStrap,androidLockpattern).The libraries can be seen under the root directory of my android studio project,but when i click build i keep getting the following errors

G:\AndroidstudioProjects\P3 Authentication\p3Authentication\src\main\java\com\p3authentication\Captcha_Verfication.java
Error:(11, 45) error: cannot find symbol class Settings
Error:(25, 18) error: cannot find symbol variable MATRIX_WIDTH

I know all these classes and Variables exist because when i run my application from eclipse it runs perfectly without any problems. Any idea how to overcome this is gratefully accepted

One source of this problem is that if you're using library modules, you need need to use the plugin "android-library" for them to be packaged and available to your application. IF you're using gradle to build your libraries and have dependencies on them using the compile project(":UIL") this might be your problem.

Mutliproject setup with libraries :

In the build file for each of your libraries, you should probably have the line:

apply plugin: "android-library"

I think it might ask you to correct this from android-library to com.android.library
