I investigated spring for android and my analysis is :
It Does not provide Inversion of control. Provide popular spring tools like RestTemplate, Social Integration for Android . Spring provides parsing framework as well, thought not as efficient as jackson. more yet to be added, keep your finger crossed.
this means whenever you want a ready made solution for RESTor Social Integration(fb/twitter) along with a parser with normal capability, spring for android might be a right choice for you.
if someone will post more accurate answer, i will surely accept that.
