You didn't give us enough information. NullPointerException can be thrown for many reasons.That error means that an application attempts to use an object reference that has the null value.
I am wondering if this is some bug in Android Studio or I am simply lack od knowladge but straight to the point.
I am writing simple client-server via bluetooth app on android. At some point I encoured following problem:

For what I understand Android Studio can't find method parujUrzadzenia(View) that is marked in button6's properties as onClick method...the funny thing is i deleted this button in my way of solving this problem.
I can't post picture of my project due to low reputation but like I said. I've deleted the reference to method from .xml and method from .java file and got an error saying that there is no required onClick method. So I deleted this whole button and still got this error.
Any advices will be greatly appreciated.
my application crashed when I start it again after closing it for quite some time. Below you can see the log that shows the error:

I'm looking for the solution or at least someone with similar problem but surprisingly there is none.
Someone can help me?
Thank you!
I've taken the code from Android's own Audio Capture documentation and ran it to achieve just what the docs say. As is, the code crashes when I click the "Start Recording" button and the crash says the following:

If I place AudioRecordTest() at the very beginning of the startRecording() method, the crash ceases until I finish the first recording and then press "Start Recording" again, the crash reappears with the following message:

The code I'm using is the exact same code as that of the docs (linked above), and the "MainActivity" file that the exception is pointing to can be found here: http://pastie.org/8682455
Any clue? what baffles me is that the code is pasted as is, straight from the docs, and still it fails..
Thanks
I'm seeing a weird exception in Android Support Library - the stack trace is below. Any ideas what could be causing this? I'm unable to reproduce the exception on any of my devices, but there seem to be quite a few visible in the Google Play DevConsole.

try check stack fragments in time rotate screen for example in onResume.
