This bug happens when the versions of SDK, Build Tools and Gradle Plugins doesn't match (in terms of compatibility). The solutions is to verify if you are using the latest versions of them. The gradle plugins are placed in the build.gradle file of the project. Other versions are in the build.gradle file of the module. For example, for SDK 25, you must use the Build Tools 25.0.2 and gradle plugins version 2.2.3.

Clean the project after changing settings.
