Although I'm not certain, it looks like a male bee from the genus Osmia. I agree with Alex, that a better picture might yield more exact results (so long as you provide the photo to the right person). According to Discover Life's Global Mapper, the two species of Osmia in India are O. fasciata and O. adae.
I have checked of what Valerie has suggested, but like what you said there's the white hairs on the legs and two black short lines on the underside of of the white hairs of the forelegs. So, probably its not Heriades truncorum.
