Answer 1

You need to use ContextCompat.getColor(), which is part of the Support V4 Library (so it will work for all the previous API).

ContextCompat.getColor(context, R.color.my_color)

You will need to add the Support V4 library by adding the following to the dependencies array inside your app build.gradle:

compile 'com.android.support:support-v4:23.0.1'

If you care about theming, the documentation specifies that the method will use the context's theme:

Starting in M, the returned color will be styled for the specified Context's theme
