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:
FATAL EXCEPTION: main
java.lang.IllegalStateException

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
Decided to use Scandit SDK to get the barcode scanning feature in my app. Unfortunately, since I'm relatively new to Android development and Java in general I've run into a few issues that I can't seem to work out. The demo that Scandit provided doesn't give any errors(runs fine) but crashes when I try to start it up (pressing a button from one activity is meant to start it up). I've tried reading the logcat and googling a solution to the problems but I'm not getting the right solutions. Does anyone have an idea of what I'm doing wrong?
Logcat is provided below:

I came across this problem as well, my solution was to extract the library files and put them as their files in the lib folder
The library basically isn't being exported with it
EDIT
So I checked out my project, basically I did these things:
In the libs folder I have a new folder called armeabi and inside that I have libscanditsdk-android-3.3.1.so
Then in my build path I have also referenced the jar file that they provide:
<classpathentry exported="true" kind="lib" path="C:/GIT/Android/FwayScannerProject/FwayScanner/libs/scanditsdk-barcodepicker-android-3.3.1.jar"/>
In 4.0.3 if i am using a base theme in my manifest, it appears to Android is trying to resolve my onClick methods of my menu's in the android.view.ContextThemeWrapper class. It resolves fine in 4.03+. I can take out the style in the manifest and everything works and gets resolved. How can I get the onClick methods to resolve correctly while using a theme?
I'm inflating the menu in the onCreateOptionsMenue() method and that's where the exception is getting thrown.

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.
