java.lang.NoSuchFieldError android/support/v7/AppCompat/

I had a similar problem after upgrading to Android Studio 2.0 and Android Support Library 23.3.0. The error was

java.lang.NoSuchFieldError: No static field AppCompatTheme of type

I solved it by going to Android SDK Manager. Updates were available for following:

• Android SDK Build Tools
• Android SDK Tools
• Android Support Library
• Google Repository

Updated and ran the app again, that solved the problem.

Edit:

If you have already updated above mentioned things and still have problems, as @mparkes pointed out in comment, check if you have updated the build.gradle(app) file to use the latest library as following:

dependencies {
    compile 'com.android.support:appcompat-v7:23.3.0'
}

Then rebuild the project: Build Menu > Rebuild Project

I also had this problem after upgrading to Android Studio 2.0. In my case it was Instant Run issue. There is a bug in AOSP Issue Tracker.

So disabling Instant Run helped me.

• Open the Settings or Preferences dialog.
• Navigate to Build, Execution, Deployment > Instant Run.

Apparently I needed to update my SDK tools and SDK platform-tools, after that I was able to select 5.1.1 as build target for my appcompat v7 library project.
