I am trying to reduce my apk size (because google play services increased size of my app from 65kb to 5MB) using shrink as told in this web: http://tools.android.com/tech-docs/new-build-system/resource-shrinking

i added minifyEnabled true and shrinkResources true

The problem is that as told in that web this should be displayed in gradle log: 

:android:shrinkDebugResources
Removed unused resources: Binary resource data reduced from 2570KB to 1711KB: Removed 33%

But nothing is displayed in gradle log.... only this:

Executing tasks: [:app:assembleDebug]

Configuration on demand is an incubating feature.

this is my code:

apply plugin: 'com.android.application'

    Your Gradle output is from a `debug` build. Your rules are in your `release` build type. Do a `release` build to see whether or not your rules are working. – CommonsWare Jan 09 '15 at 13:38
  • you are on true, thanks a lot :) btw my apk is still with a huge size!! 3 megabytes :( – NullPointerException Jan 09 '15 at 15:38

    The `play-services-ads` library is 380KB, and it depends upon `play-services-base`, which is 1.1MB. That in turn depends upon `support-v4`, which is another 860KB. Minification and resource shrinking are inexact sciences, and so I am not terribly shocked that your APK grew by a fair bit. You might consider adding `resConfigs` to your Gradle script, per Cyril Mottier's [blog post on APK size reduction](http://cyrilmottier.com/2014/08/26/putting-your-apks-on-diet/). Or, use a less pudgy ad network. :-) – CommonsWare Jan 09 '15 at 15:52
