How to run J2ME application in the background on startup

[Efigenio]

Actually, I am facing some problem with the some queries of J2ME application.
1. There is any possibility to run J2ME application on a S60 device in the background
2. If this is possible then how can we switch to foreground again.
3. One more thing is there any way to run these applications on the startup.
I will be waiting for the related replies.

Well if you are trying to run the applications such as doing the network connection in the background and showing the “Please wait” screen in the foreground screen. Then this can be done using two threads. The first thread will do the operation on the background and the second thread will show the screen in the background. But if you are talking about running two application on the foreground then as per my knowledge it is not possible.

You can try to use MIDP 2.0's Push Registry for having an application that will be activated leading to the notification.



The PushRegistry API allows you to register push alarms and connections, and to retrieve information about push connections. A typical push registry maintains lists of connection and alarm registrations in both memory and persistent storage.

Thank you for the reply, But I am searching for a method for running my application in the background. I mean the application should run all the time and the user should be able to use the mobile phone without noticing that the application running in the background. Can you suggest me some better answers.

Yes, you can run the background application on all the S60 and on Sony Ericson devices. You can do this by setting the currentdisplayable value to null and keep threads running in the background. The other option is that you can press the Menu key, then start another application, and push the old application which running in the background.
