run J2ME application in the background on startup

[schmida1980]

Hi folks,

can you please help me with some questions on J2ME applications.

1. Is there a possibility to run a J2ME application on a S60 device in the background?

2. If so how can it be switched to the foreground again?

3. Is it possible to automatically run the application on startup?

Thank you in advance!

Thank you very much for your help Wang!

The topic discussed in this thread is not what I am looking for. It doesn't help me to set my application to sleep and awake it on a push event.

I am searching for a mechanism to make my application run in the background. The application shall run all the time, but the user should be able to interact with his mobile device without noticing the application is running at all. From time to time the application shall notify the user about certain results of the processing and disapear again afterwards.

Does anybody know how to achieve this?

Furthermore I want to register the application to run on sartup of the mobile device. How does this work?

Hi schmida1980,

3. Is it possible to automatically run the application on startup?
AFAIK this is planned for future Series 40 devices, there's a JavaOne 2006 presentation briefing on that.

Some recent phones of S40 may support J2ME background running app but not all phones. You can try creating such application using Symbian platform.

1.Possibility to run a J2ME application in the background? --- Yes, you can run background app on all S60, recent S40 and recent Sony Erricson and other devices as well. You can try it by setting currentdisplayable to null and keep some threads runing in background on these devices. Or press the Menu key and start another app, pushing the old runing app to background.

2. Can we run the application on startup? --- Yes, you can do by Jad Attribute - Midlet-auto-start: yes, on various platforms like on Nokia it becomes: Nokia-Midlet-Auto-Start: On, on SE devices JP7onwards you can try PushRegistry with ://autostart: etc.

I used setCurrent(null) and it works on Nokia N79. i.e. the midlet hides. But when i use setCurrent(myCanvas) to again put the midlet in foreground it does'nt do any thing.
So my question is How can we make midlet in the foreground again ?

I couldn't make the midlet-auto-start nor the nokia-midlet-auto-start JAD attributes work in a Nokia 5230.

I couldn't make the midlet-auto-start nor the nokia-midlet-auto-start JAD attributes work in a Nokia 5230.

Jad attribute Nokia-MIDlet-auto-start Works only on the S40 devices with the Series 40 3rd Edition FP 2 onward. However you need to get the MIDlet signed from the Manufacturer / operator domain.

Possible values:

yes
no
once
Example: Nokia-MIDlet-auto-start: yes

The device you are referring to is of the S60.

So there's absolutely no way to make a midlet autostart in a S60...?

It is not feature of J2ME, but it depends on platform in which MIDlet runs,
