I just had the same problem and found a way to solve it (You can do this with Android Studio open):

• Go to you Android Studio projects folder located in c:\users[USERNAME]\AndroidStudioProjects
• Locate your project folder and open it.
• Delete the folder named build.
• From here, enter your application name folder, where you can find another build folder among with libs and src folders and a file named build.gradle.
• RENAME the build folder to build2 or something else.
• Now in Android Studio go to Build->Rebuild Project.
• And after the project was rebuilt, open again the folder where the build2 folder that you renamed is located.
• Delete the new folder named build that was created.
• Rename your build2 folder to build again.

Done.
