Re: what does "uncaught exception:java.lang.Error" mean, it appears on my screan

Hi there!

 

  • KB14726Uncaught exception: java.lang.error is displayed when the BlackBerry smartphone is reset
  •  KB20186Uncaught Exception on first bootup after using the Device Switch Wizard in BlackBerry Desktop Manager
  • KB13323Uncaught exception errors appear on the BlackBerry smartphone

 

While the above KBs (and more!) exist, 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. Alternative methods for bringing up the logs are in this KB:

  • KB05349How to enable, access, and extract the event logs on a BlackBerry smartphone


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. Still another method is to reload the BB OS cleanly, leaving some time between adding other apps onto the BB so as to be able to determine exactly which one is the cause.

 

Good luck and let us know!
