How to start Login Activity if user wasn't active for 5 minutes:

问题

I need to start the log in Activity if the user wasn't active for 5 minutes in the application ,without considering from what activity he left the application. (by not active for 5 minutes I mean that the user didn't commit any action to the server side)

I have a Date variable inside my Application class:

private Date timeOfLogin;

that's is saved when the user commits log in, in some point of usage the user can get a phone call or a mail and will leave the application. now this can happen on any screen of the application. And now when he turns on the application again /return to it after finishing his phone call I need to show the log in screen again and not his last activity if 5 or more minutes have passed.

How can it be done? do I have to override every onResume of each activity I have in the application and start the log in Activity if the difference between the timeOfLogin and current date is bigger then 5 minutes? or is there a better way to do that?

Any help would be appreciated.

Thanks.

回答1:

Have an activity that all of your other activities extend and put the logic in that activity's onResume. (You'll probably find this practice to be useful in a lot of other ways too)

回答2:

Create a CountDownTimer with 5 minute count down in your ResponseHandler class in the onFinish() show the login dialog. If there is any response cancel the timer and start again.
