If nothing of this helps , Create a new android Project and check its build.gradle(module:app) and check for constraint compile/implementation. Copy that to your app build.gradle(module:app).

That should do the work :-)

Well, I had the issue, that I updated the the ConstraintLayout and Solver dependecy like it was suggested it in the posts above. But still had the issue. My problem was, that the SDK Tools updated it to the latest version, in my case it was 1.0.0-alpha9, but in my gradle dependency was set to 

compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha8'

So, you can change your gradle build file to 

compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha9'

Or you check "Show package details" in the SDK Tools Editor and install your needed version. See screenshow below. Image of SDK Tools

In Android Studio select: SDK Manager -> SDK Tools -> check 'com.android.support.constraint:constraint-layout:1.0.0-alpha4' in bottom of list and press 'OK' for installing this and updates, proposed by Android Studio.

I've found the fix:

  • Download Android Studio 2.2 Preview 7
  • Update SDK Tools to the latest 25.2.1
  • Download ConstraintLayout and Solver for ConstraintLayout in SDK Manager as per image below
  • Add com.android.support.constraint:constraint-layout:1.0.0-alpha5 to gradle.build
