Thanks for your submission! We would love to have this new input element.

We have to check with existing users to see if they can move to SDK 16 minimum. Some do a lot of research in India where 4.0 was still fairly prevalent not too long ago.

[BobEvans]

Is there something in this change that requires sdk 16? If not, please revert so we are supporting back to Android 4.0.

The SeekBar.getThumb()-function needed API 16.
But I created a fix that also works in API 14 :)

Hi @JodliDev this is very cool. Is there any code to show the scale in the Preview (server side). All I can see is the question text, but nothing under it.
Are you planning on adding any more configurable attributes like scale or indicator text?

In case you are interested, I added a default material slider to the server preview here: josmas@9c2b33b

Also fixed the services.js conflict but I bumped to API 16 and set limits to 0-100 for now, cause it is what I need. Happy to back port or add functionality if there's a need for it.
