Answer 1

This looks like a Plugin conflict/problem.

Copy your google-play-services_lib folder to your project's Plugins/Android folder.

OR

Remove all your Plugins at Plugins/Android then re-import them but uncheck google-game-palay services_lib folder when re-importing them.

Answer 2

Unity is running aapt.exe from build-tools/24.0.0 ( you can see the path of aapt.exe in the log). Version 24 is for Android N (the next upcoming version Android), which is not supported by Unity at the moment (many developers are complaining about this exact issue).

In order to resolve this issue, you have a few different options:

Under your Android SDK folder, remove version 24.0.0 of build-tools (sdk/build-tools/24.0.0).

You can do the same from the Android SDK manager (select build tools version 24 and then "delete package")

SDK manager

In case you need that version specifically, you can install another Android SDK that will only be used with Unity. In this installation, do not include build-tools 24.

Lastly, you should try to upgrade to the latest Unity version, as this issue should be solved (I believe it was solved in 5.3.5p4).
