问题 I'm looking for a way to quit my android app by code. Yes, I know, I shouldn't be doing this cause android handles it when you press the back button, but I have a customized flow that forces me to implement this.

What is the canonical and correct way to quit? UPDATE: Serge I believe is right that in InitInstance() returning false is the correct way to quit the application. However, now

问题 How should I quit a Qt Program, e.g when loading a data file, and discovered file corruption, and user need to quit this app or re-initiate data file? Should I: call exit(EXIT_FAILURE) call QApplication::quit() call QCoreApplication::quit() And difference between (2) and (3)? 回答1: QApplication is derived from QCoreApplication and thereby inherits quit() which is a public slot of QCoreApplication , so there is no difference between QApplication::quit() and QCoreApplication::quit() .
