Answer 1

• In case you administrate your own aar files:

You have to ensure that your gradle and buildToolsVersion are identically in your project and the used aars.

• In case you use external libs where you can't control the gradle/build version:

Contact the author or check the sources by your own. Some libraries have unused launcher icons which will cause this conflict. Removing this icons will solve your problem. Identically named sources (e.g menu.xml) could also cause this issue in rare cases. An easy workaround would be to rename your ressource.
