• fire an intent from the onCreate method in android

  - by Sephy

  Maybe my question might seem a bit weird, but I have an activity in which, in one case , I have to move to another activity before it finishes loading the screen. My condition is in the onCreate method, which means when I encounter it, i get a "startActivity called from outside an activity context" error and the app just crashes... But then, is there an easy way like a flag for the intent to make it work without having the activity context resolved? thanks for any answer

• c++ volatile multithreading variables

  - by anon

  I'm writing a C++ app. I have a class variable that more than one thread is writing to. In C++, anything that can be modified without the compiler "realizing" that it's being changed needs to be marked volatile right? So if my code is multi threaded, and one thread may write to a var while another reads from it, do I need to mark the var volaltile? [I don't have a race condition since I'm relying on writes to ints being atomic] Thanks!
