None of the above solutions worked for me.

I didn't have a toolbar in my project, but got the same error.

I cleaned up the project, uninstalled the app. Then I ran a gradlew build --refresh-dependencies, and found out there were some onclick events without corresponding code in the xml files.

I removed them, rebuilt the project, and it worked.

The dependencies didn't seem like were updated, but that's another story.

I know this is an old question  but I recently ran into this same issue  It ended up being a Proguard problem  when I set minifyEnabled to false it stopped happening    To stop it  with proguard enabled  I added the following to my proguard rules file  thanks to a solution I found elsewhere  after discovering that the problem was proguard   -dontwarn android support v7    -keep class android support v7           -keep interface android support v7             Not sure if they re necessary  but I also added these lines   -keep class com google           -keep interface com google

I face the same problem but that was after I had updated to appcompatv23 2 0  I tried all the above suggestions but dint work  Then I proceeded to my Gradle file and replaced   dependencies   compile  com android support appcompat-v7 23 2 0    compile  com android support design 23 2 0       with   dependencies   compile  com android support appcompat-v7 23 0 1  compile  com android support design 23 0 1      Rebuild the project and the issue was gone  It could be an issue with app compact v23 2 0  hopefully a better solution coming up so we can work with the new update   Hope this helps  Thank you

I faced with same problem   Solution that worked for me   If you use v7 Toolbar you must use theme extended from Theme AppCompat   You can t use theme extended from android Theme Material   because they have different style attributes   Hope it will helpful

If you are using new androidx implementations  when typing Toolbar  the Studio will autocomplete it to android support v7 widget Toolbar  but you should use androidx appcompat widget Toolbar instead  otherwise you will get this error

To fix this problem   first you must add latestandroid-support-v7-appcompat from the   sdk extras android support   Close the main project  Remove the android-support-v7-appcompat   Restart the Eclipse  Add the  android-support-v7-appcompat   Clean To build the project  Then open the main project and build all the projects  The error still remains  Restart eclipse  That s it    That works for me and I will strongly recommend you to use Android Studio
