Can't build for android - Faild to re-package resources

Hello! I've encountered many problems while trying to make building apk-s possible in Unity3d, but this one consumed a lot of my time. Every time I try to build an apk I get this error:

 CommandInvokationFailure: Failed to re-package resources.
 C:\Users\Olaf\AppData\Local\Android\Sdk\build-tools\24.0.0\aapt.exe package --auto-add-overlay -v -f -m -J gen -M AndroidManifest.xml -S "res" -I "C:/Users/Olaf/AppData/Local/Android/Sdk\platforms\android-24\android.jar" -F bin/resources.ap_

I've been trying to use many different solutions that I found on Internet, but nothing seems to work for me. Or maybe I'm doing something wrong? I would be thankful for any advice. I thank you very much in advance for any help!
