After migrating from eclipse my APK size grew roughly by 1.5MB.
Checking in the .iml file I see: `<orderEntry type="library" exported="" name="appcompat-v7-22.0.0" level="project" />`
I guess AS includes appcompat always. Even if not required by `build.gradle` script and not used in the app. 

`R.java` also has tons of references to appcompat.

I repeat my `build.gradle` has no reference to appcompat:

```
dependencies {
    compile 'com.android.support:support-v4:22.2.0'
    compile 'com.google.android.gms:play-services:7.5.0'
}

```

Does anybody have this issue?
