The answer is here: Which programming languages can be used to develop in Android?

As it is a Regular post, I have also got +195 points for the 18 upvotes and 15 for accepted answer, but now it is showing as "Community wiki".

Whats the reason behind that ? any rule ?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

No wonder many highly voted answers are cw on stackoverflow. I always had thought some users here really dont care about rep and they just graciously and willingly make it cw.. Now I know its not :) – nawfal Jan 15 '13 at 20:08

Your 12th edit made it so automatically, see the revisions. For further explanation see Why did my answer become community wiki, history says I did that, but I didn’t and the CW-FAQ:

How does a post become a Community Wiki post?

There are several ways a question or answer can enter community wiki mode, and most of these ways will occur automatically based on the rules of the system.

Posts enter community wiki mode when:

  • The body of the post has been edited six (6) times by at least four (4) different people.
  • The post has been edited eight (8) times by the original owner.
  • The post's author checks the community wiki checkbox when composing the question or answer. Note that this checkbox is only available to users with a reputation of 15 or more.
  • The post is edited by its original author, who when doing so opts to check the community wiki.
  • An answer posted to a Community Wiki question will also be Community Wiki. Note that when a question is made CW after answers have already been posted, the existing answers are not normally converted to CW automatically.
  • The question generates more than 30 answers (15 on Super User). In this case, the question and all answers will enter community mode, as will any future answers.
  • A moderator has reason to believe that the question serves better in community wiki mode.

* note that the rules outlined above are based on observations; the actual behavior of SO is subject to change without notice, and may well have done so since this was last updated...

So why didn't it happen on the 8th edit? Is that info out of date or do some edits not count? – Martin Smith Aug 9 '10 at 12:41
@Martin Smith: as the * note states, the actual behavior of SO is subject to change without notice, and may well have done so since this was last updated... – Tobias Kienzler Aug 9 '10 at 12:47
Yes I read that as well. I suppose either way the information is incomplete or out of date but if anyone can confirm that the limit is now 12 that would be useful to know. – Martin Smith Aug 9 '10 at 13:06
@Martin: Edits in a short (five minute?) widow are treated as one by the system. That is, their edit comments are merged, they "editted <time> ago" bit shows only the first time from the clusters, and (I believe) they count as one edit for CW bookkeeping. – dmckee Aug 9 '10 at 16:03
@Martin Smith Ya exactly...why didn't it happen on the 8th edit ?? – Paresh Mayani Aug 10 '10 at 5:07
@Tobias Kienzler you have told that "An answer posted to a Community Wiki question will also be Community Wiki." then check out my question ->… , here y didnt it marked as "Community wiki post"????????? – Paresh Mayani Aug 10 '10 at 5:10
@Paresh Mayani: because you turned the question CW at 13:02 (see revision) but posted the answer at 13:00. When a question is turned CW, the answers remain unchanged unless a mod turns everything CW. You have to manually turn your answer into CW if you want. – Tobias Kienzler Aug 10 '10 at 7:11
@dmckee: those edits are not even kept track of, i.e. they won't show up as different revisions – Tobias Kienzler Aug 10 '10 at 7:11
