Recently I saw some really cool applications in my friends Android phone. Some apps even allowed him to schedule his daily routine work , also he told me that now when ever he faces any problem with his phones application he takes care of them all by himself. When I asked him how he does so, he told me that he has joined a community called Android community which helps him in it for free. Can anyone tell me how can I join thins community? Also is there any subscription charge to join the community?
