i'm sorry if my responses seem flamy but the majority of the work i've had lately is fixing code of programmers like asshole here who have no idea how to prgramm. How do they get jobs? I just wonder and wonder.
|
|
Do the clients go on like freelancer.com hoping to get low bid? Don't you know that's how you get FUCKED? I mean, at least hire some talent European (like the people who mange this list) or fucking stop hiring Indians who don't know how to program, write shiity, shitty, code, and end up on lists like this asking stupid ass questions about shit that the developers don't need to help then with. If you can't use c# how it should be, why are you using it to write an android app. You know it's gonna leak memory and fail... fucking shit programmer.
|
|
|
|
I swear to god I might just hire someone to beat the shit out of these guys. That might teach them to not take jobs that they can't handle.

Activities are tied to their Main thread -- it isn't safe to interact with them except via the main thread or Activity.RunOnUiThread() -- and anything associated with the Activity follows the same rules as well. This would include the LastNonConfigurationInstance value, as used at:
