Change color of Switch in Android

As per this, (direct answer by BoD copy-paste):

• You must not use android:thumb and android:track, but instead, app:thumb and app:track And you must add the following to the root of your xml document:

  xmlns:app="http://schemas.android.com/apk/res-auto"

Easiest way in Android Lollipop and above,

<style name="AppTheme" parent="MaterialTheme.Light">
    ...
    <item name="android:colorControlActivated">@color/color_switch</item>
</style>
