Update: I got Vector Drawables working on API Level pre-20 devices with teh following configuration.

build.gradle
vectorDrawables.useSupportLibrary = true

dependencies{classpath ‘com.android.tools.build:gradle:2.1.2’}

Activity
onCreate > AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);

ImageView — XML
app:srcCompat=”@drawable/vector”

ImageView — Programmatic
imageView.setBackgroundResource(R.vector);

vector.xml

`<vector xmlns:android=”http://schemas.android.com/apk/res/android"
android:width=”30dp”
android:height=”20dp”
android:viewportHeight=”20.0"
android:viewportWidth=”30.0">
<path
android:fillColor=”#4C5F70"
android:pathData=”DATA_HERE”
android:strokeColor=”#00000000"
android:strokeWidth=”1"/>
</vector>`
