I am developing a mobile app using j2me. It works fine in "sony ericsson z530i". It works fine in "Nokia c2-00" mobile before 1 week. But I run the app now in nokia phone after sometime in the middle of app automatically my nokia phone switches off. I cannot resolve it but it works fine in sony ericsson mobile. I think I need to change some phone setting or the phone is in problem? I cannot find a solution so please help me solve the issue. I am using "Nokia c2-00" mobile which had "S40" sdk.
Some time problem may be in MIDP version in the mobile application check whether property and select MIDP as 2.0.
I find the solution.The problem is not in mobiles is in my application.It will not run due to ran out of heap memory.
Now i modified my code with respect to decrease the memory leak.Now its working in all mobiles which have the configuration cldc1.1 and midp2.0

I can't give you the code, because it is my companies app. But I would be really appreciated if you know sth. about this difficulties and give me some evidences.
Thank you!
I was to develop a simple j2me application for microworks. The application is to send sms.
But I found that most of the mobile phone they carry are very simple and even some of them don't have Bluetooth, infrared, browser. How to make it work out?
We can assume configuration as nokia 2100, nokia 1616. How am I supposed to deploy my app on such handsets?
OTA is required to work on every MIDP mobile device, just navigate with the device browser to the jad URL and click it.
I downloaded Sony's most recent SDK which includes an unusual Emulator that is an APK that runs on an Android phone (I guess that is what you do with it).
Anyway I see no documentation about how to use this to test/deploy apps.
Am I supposed to have 2 phones and one runs the emulator and the other runs the "host application" or do I run the host application on the same phone or what?
Nothing that I can find in docs explains this.
So I've figured this out (sort of). You run the emulator on your phone, then run the Smart Extension app on your phone as well (so no bluetooth connectivity like when you have a real smartwatch).
Phone also needs to have the SmartConnect (previously LiveWare) app and the SmartWatch app installed (I think). So that's three apps (emulator, SmartConnect, SmartWatch app).
Anyway, my actual smartwatch arrived in the mail shortly after I posted the original question, so I probably won't be using emulator much anymore.
I have a PhoneGap app that works perfectly on the iPhone 3.2 simulator and also iPhone 3 and 3GS devices.
I have just downloaded and installed the latest iOS SDK, changed the settings in Project>Edit Project Settings to allow the application to work, and run it successfully within the iPhone 4 simulator and even the iPad simulator.
However when I run it on a provisioned iPhone 4 device, nothing seems to happen when I run it. I get the splash screen, but nothing happens after that. In the log I get this:-
2010-09-13 10:11:34.156 MyApp[89:307] Going to play default movie
2010-09-13 10:11:34.169 MyApp[89:307] Can't find filename default.mov in the app bundle

2010-09-13 10:11:35.037 MyApp[89:307] Free space is 15497396224
And nothing else!!
Really annoying. Anybody know what might be happening here? I tried fiddling with a few settings in the Project Settings but that doesn't seem to have fixed it.
Any help would be really appreciated.

Update - my problem. I had some external javascript which was crashing due to the way I was calling it from the HTML file. Weird that it only affected the iPhone/iPad device but not the simulators, but there you go....
I have written a simple midlet that invokes itself after a socket connection from a server program. I am using Push Registry to do this. It works fine on all the test phones I have immediately after installing. but if I reboot the phone, the push registry stops working on N86 whereas it is working on the other test phones that I have viz. N97 and ExpressMusic 5800. Has anyone faced such a problem before? Any kind of help will be appreciated.
btw, after going a little deep into the specifications of these phones, I found out that though all the phones are MIDP 2.1, N86 has Symbian OS v9.3 and the rest two have v9.4. Can that be the reason for the behavior of N86 ?
I did a hard reset (press *#7370#) on the phone (N86) and everything is working properly! I still don't know what the problem was!
Find the documentation of the error in nokia page:
http://wiki.forum.nokia.com/index.php/KIJ001317_-_Push_registrations_for_Bluetooth_MIDlet_turns_off_in_the_latest_S60_3rd_Edition_devices
The phones that are affected are:
Nokia E75, Nokia N78, Nokia N79, Nokia N96, Nokia 5630 XpressMusic, Nokia 6720 Classic, Nokia 5800 XpressMusic
Worst of all, you say there is no solution.
