Android Studio seems to build old version of project

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:
07-11 18:59:20.553 10364-10364/? E/AndroidRuntime﹕ FATAL EXCEPTION: main

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.

Android HDR scene mode

I'm trying to implement an app that take photos using HDR mode.
My phone is an Galaxy S3 and in the native camera, I have the option to enable HDR.
However, I'm getting an exception when setting it in the app.
I set the HDR like this:
params.setSceneMode("hdr");
Then, when I try to set the params back:
mCamera.setParameters(params);
I get this exception:
java.lang.RuntimeException: setParameters failed

Any help? What am I doing wrong?
I have also tried to use the constant:
params.setSceneMode(Parameters.SCENE_MODE_HDR);
Same error.
Thanks!

Trying to find Android App ANR reason

Has anyone had an issue where their Android app has gone ANR when being resumed from background with the main thread getting stuck at:
at android.view.GLES20Canvas.nFinish(Native Method)
It seems to happen to me after sending the app to the background multiple times, after drilling down between 3 to 4 activities on the stack then going back up to the root activity multiple times.
Here is a complete stack on main thread before ANR:

I have just confirmed that I can not recreate this bug on a device Acer 100 7" Tablet running android 4.0.3
My other test device Nexus 4 running android 4.3 recreates this bug with certainty on around the third time resuming the app after opening 3 or more activities on the activity stack with in application.
Weirdness. Also seeing it on an HTC running 4.4

NullPointer exception at android.support.v4.app.FragmentManagerImpl.makeInactive

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.

Missing layout_height attribute stack trace?

I'm continuing to dig through marketplace crash reports, and have come across another one which I can't make any sense of. The stack trace:

So I'm being told that layout_height is missing in one of my layout files on a line #17? But I don't know which layout file from the stack trace. I'm going through them one by one to see if I forgot the layout_height attribute anywhere, but I have lots of them and wanted to see if I'm missing something obvious here.
