PR #27

[EmperorEarth]

If you don't want to bump the compileSdkVersion and buildToolsVersion to 26.x, you can import android.util.Base64; instead of import java.util.Base64; on Line 25 and use 26 instead of Build.VERSION_CODES.O on Line 219. There's probably more changes you'd have to make--I didn't chase down that rabbit hole--but I don't see any reason why it needs to require 26.x+
