AC Question
For example I am going to register in somewhere and acidentally my browser or system crashing in android. So I would like to know how to program an app which helps to revert a saved point into tabs. Visitor only have to retype the secret code which means that the recent information is already reactivated. Which language I should learn: java/c++/javascript or should I have to learn something else. Any sites or examples are welcome about the documentation style.
