Re: Uncaught Exception: Java.Lang.NullPointerException

I am having a similar problem over the past week, where I receive an error that says "net_rim_bb_qm" and crashes my BBM.  I recently upgraded to the newest BBM and since then I've been receiving these errors.  The errors also crash my Address Book, because I cannot open individual contact files.

Re: Uncaught Exception: Java.Lang.NullPointerException

Alright, this is what u need to do.

1.Backup your device

2.Download the last version of your HH software of your device from your carrier web page or go to www.blackberry.com > choose your country > then go to Support and Services > then on your left side and hit download > Access my service provider download site > pick up your carrier and then your device model and download it and install it.

3. Reload the software on your device, how to do that go to www.blackberry.com/btsc and look for the KB11320


Is the only way to fix your problem.

Re: Uncaught Exception: Java.Lang.NullPointerException

I'm getting the same error message (Uncaught Exception) and I can't use the Desktop Manager because my device is not being recognized (even though the PIN is correct).  Any advice?

Hi and Welcome to the Forums!!


There's pretty much no diagnosing those -- they are the equivalent of the random errors in Windows for which tracing the root cause is fruitless. Basically, these are the last out in the programming code -- some event occurred for which there is no handler in the code. The fix is a code update that handles the event...but, again, knowing what the event is is pretty much impossible. So, there are a few things to try:


Sometimes, the code simply becomes corrupt and needs to be refreshed -- just like a reboot:

  • Anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.


There might be an updated code set from the carrier -- check them via this portal:


The toughest possible cause is a badly behaving app. To find it, there are a couple of options. One is to see if you can read the log file:

Go to the home screen. Hold down the alt key and type 'lglg'. (You will not see anything while you type).This will bring up the log file. Scroll down (probably many pages) untill you see a line that says 'uncaught execption'. Click on this line. The name of the app will be in the info.

The other method is to remove apps one at a time, waiting a while in between (I usually recommend a week), until the problem ceases...thereby discovering the offending app.


Good luck and let us know!
