Thanks Shantanu, looks great. Like the enhanced UI direction you took (radio buttons, custom value, etc). You made the UI/UX your own, and probably learned a lot more from this project as a result. A few more notes:

• Good layout, proper view naming, usage of sp/dp, margin and relative placement rules
• Good use of string resources for text values
• Source activity works fine, properly formatted and works as expected
• Nice use of methods to break of complexity as you attach the various listeners
• Did error handling for empty input value cases

Hopefully this has given you a first sense of the RelativeLayout which is a very powerful layout system, probably one of the best responsive-first layout systems available across web and mobile platforms. Let us know if you have any other thoughts or questions about the assignment.

The next assignment will build on top of the first concepts introduced here and will also introduce networking, api use, handling remote images and navigating between activities.
