Can I have an android activity run only on the first time an application is opened?

阅读更多关于 Can I have an android activity run only on the first time an application is opened?

问题 OK, so I'm playing around with an android app. The 90% use case is that users want to go straight to the primary list screen to find what they're looking for. That's what I want as my default screen. The first time a user loads the app however, some configuration is required before their list screen is of any value to them.

How do I force an application-scoped bean to instantiate at application startup?

阅读更多关于 How do I force an application-scoped bean to instantiate at application startup?

I can't seem to find a way to force an application-scoped managed bean to be instantiated/initialized when the web app is started. It seems that application-scoped beans get lazy-instantiated the first time the bean is accessed, not when the web app is started up. For my web app this happens when the first user opens a page in the web app for the first time. The reason I want to avoid this is because a number of time-consuming database operations happen during the initialization of my application-scoped bean. It has to retrieve a bunch of data from persistent storage and then cache some of it

In addition to that, in that batch file, I would like to be able to say: Once I execute a program, wait until that program completely loads, and execute the next listed program. Any help would be appreciated. I had the same issue in Win7 regarding running a script (.bat) at startup (When the computer boots vs when someone logs in) that would modify the network parameters using netsh. What ended up working for me was the following: Log in with an Administrator account Click on start and type “Task Scheduler” and hit
