Analysis: Suppress get color deprecated warning

Warning Message: "'getColor(Int): Int' is deprecated.
Deprecated in Java"

FYI: This is being suppressed instead of it being resolved since the
'minSdkVersion' is also about to be update to '24' and as such this
'Build.VERSION.SDK_INT < Build.VERSION_CODES.M' logic, along with
its deprecation, will get deleted altogether.
