Re: Uncaught exception: java.lang.NullPointerException

Uncaught exception: java.lang.​NullPointe​rException.

It seems this problems can't be solved unless reinstall the OS. Why BB have many problems? iPhone seems not. RIM is supposed to improve the technical level. Desperately I have to reinstall the OS and lose all applications installed. OH, god not help BB.

Re: Uncaught exception: java.lang.NullPointerException

for me none of the suggested solutions worked, basically the problem was the memory card , i removed the memory card and re booted the phone without the momery card and the problem was solved. hope its as easy for everyone else out there, its worth a try

Just re-boot your BB and it should work.

Re: Uncaught exception: java.lang.NullPointerException

I have been reposting the solution to this, given how common this error is i have to admit , im really surprised by how hard it is to actually find a working solution online, regardless, the practical way of finding the cause of the error is to simply look at your blackberry's event log and toggle the "java.exception" filter, this is how you would go about doing this:

1) alt lglg - this will show the entire event log ( the event log is huge, literally pages and pages of text)
2) click the blackberry key then select "options"

what we want to do is basically see what application or applications in the event log is causing the error,
In order to do that...

3) Click the blackberry key again... Select "hide all types"

Now we don't see anything in the event log, all the filters are unselected,

Scroll down in the list till you find the "java exception" filter, click it... You will see a small menu , select "toggle filter"

Now you will see exactly what application or applications is causing the java exception error :-)

Mine was facebook, it could be anything you never know,

Now.... Open up blackberry desktop , go to applications, remove the application or applications causing the error,

Select Update

Your device will now update then reboot, this might take over ten minutes, be patient

This will work :-)

Re: Uncaught exception: java.lang.NullPointerException

I went through the log, and found the line that said "S Java Exception- NullPointerException". I opened it up and it has the name, severity, GUID, time, and then it says "no detail message" and "net_rim_bb_messaging" and then there is a very long information summary (or I assume thats what it is). What do I do now? Thank you so much for all of your help Smiley Happy
