application-shutdown

问题 I have an application which starts a Remote Service in its first launched activity. Then, in another activity, the user can set the configuration of the application. Please note that this second activity isn't bound to the Service and I don't wish to bind it. Now my question is : how could I restart the whole application from the second activity, after changing the configuration settings? For now, I am using a button which onClickListener is : public void onClick(DialogInterface dialog, int

问题 I would like to determine the exit status of the process during the shutdown hook runtime. I want to have a logic which is based on the status code (0 or nonzero) (ex: if zero do nothing else nonzero send an alert email) Do you know how I can get this information? 回答1: I tried to override the SecurityManager checkExit(int status) method - this works if System.exit(status) is called anywhere explicitly - however, it doesn't set the status when the application exits "normally" (no active

问题 I have an RCP application that uses a connection to a in-memory database. There is one circumstance that, when shutting down windows, the application is killed without giving it a chance to close the connection to the database. I researched a little and it seems that adding a Shutdown hook is the best way to detect this event and do cleanup in a Java application. However, what is the correct way to do process this if you have an RCP application, possibly with multiple editors open? 回答1: Note:

问题 I have a bat script which runs a java application. If I press ctrl+c on it, it the application terminates gracefully, invoking all the shutdown hooks. However, if I just close the cmd window of the bat script, the shutdown hooks are never invoked. Is there a way to solve this? Perhaps there's a way to tell the bat script how to terminate the invoked applications when its window is closed? 回答1: From addShutdownHook documentation: In rare circumstances the virtual machine may abort, that is,

问题 I want to do a custom Timer app. I want it can start up and shutdown. I searched and found that starting it up needs root rights. Can anyone give me some clue to finish this? Edit: in other words:It seems nice to have an app to auto power on or power off the phone, does the hardware support?The app is only for users to set time when to turn on the phone or power off.

问题 To be able to shutdown background process (implemented with Quartz.Net) I need to detect web application shutdown in AspNet5 beta8. In previous versions of Asp.Net it was possible to execute code on Application_End. What is the equivalent of Application_End event in AspNet5? So far I tried IApplicatonLifetime in Configure, but it does not fire when I stop the web application: public void Configure(IApplicationBuilder app, IApplicationLifetime lifetime) { lifetime.ApplicationStopping.Register(
