When I found myself having to split an android application (APK file) to allow it to be uploaded onto the Google Play store, I found a serious lack of current information and much misdirection possibly due to the recent changes within Unity and the actual Play store itself.
So here is a rough guide that works with unity 4.3 or up, in this example I am only catering for devices running android 4.0 ICS or up ( API level 16), not quite sure what to do with earlier Android API versions at this very moment.
STEP -1
Firstly ignore the asset store OBB plug-in (it was created for earlier versions of unity, or possibly for catering for earlier Android API’s) going down this route will burn hours of your life.
STEP 1
If you haven’t done so already go to EDIT>PROJECT SETTINGS>PLAYER SETTINGS select the android role out and go to the PUBLISHING SETTINGS roll-out and do the following:-
1) Create a new keystore by selecting a keystore name and password (confirm the password)
2) Select “Create a new key” under Key Alias
3) A new window opens; enter the necessary information.
4) Select the newly created key.

5) Tick Split Application Binary at the bottom of this roll out!
STEP 2
Again if you haven’t already done so create a primary loading scene with very little content, this will allow unity to split most of your app data off to the OBB data/zip file and keep the APK file size small. As an example I created a scene called Android Loader, so that I could exclude […]
