AgentKnopf Answer "Make sure to add the proper dependency to the build.gradle file of your module", then I would add, you also make sure the module is same as your current version like this: compile 'com.android.support:design:25.3.1.0 if you are not using compile 'com.android.support:design**:23.1.0**'
