问题 Android Studio version 2.1, gradle version 2.1.0, please correct me if you spot any misinterpretations :) I am confused about support vectors in the support library 23.3.0. Specifically what I would like to do is tint an image button programmatically, whose src is defined is a vector drawable. From what I can tell this is not possible on pre-lollipop now.

问题 I'm using AppCompat support library in my Android project. AppCompat has plenty of drawables and resources which I don't use in my app. That unnecessary files increases my 900K app to above 2M , which I don't like.

问题 I was trying to implement preferences for an AppCompat app, using support.v7.preference.
