Solution 1:

Using

compile'com.google.android.gms:play-services:7.5.0'

Implies you are using every feature of Google Play Services, including location services. If you only need a particular API, you should be using the selective APIs.

In the case of ads, you can use solely:

compile'com.google.android.gms:play-services-ads:7.5.0'

Solution 2:

I'd recommend looking at how to reduce app size increased after admob ads?

Simply put: The library has a lot of extra stuff. You need to use ProGuard to strip that out.
