I'm new to android, what's wrong with this?
See, this is showing exception here. You have made some mistakes in your code. This is your error:
"You cannot combine swipe dismissal and the action bar"
and if you click on this line
"android.support.v7.app.ActionBarActivity.superSetContentView(ActionBarActivity.java:217) 08-28 05:27:08.570: E/AndroidRuntime(1286): at "
you will get the exact error in your Java class.
I have used ZBAR library to scan bar code in my Application.
And I got this error log while opening camera on Samsung Galaxy S3 :

EDIT :
Getting error at this line :
CameraPreview mPreview = new CameraPreview(getActivity(), mCamera, previewCb,
autoFocusCB);
Can Anyone help me to resolve this error??
Thanks in advance..
I've made my Android app tablet optimized and I followed the tutorial here:
Everything is great, but I am trying to select an item (say, the 1st item) with a button in the ActionBar.
I tried this answer to use performItemClick but on I've got error reports of java.lang.IllegalStateException
in android.support.v4.app.ListFragment.ensureList, java.lang.IllegalStateException: Content view not yet created, and java.lang.NullPointerException
in android.content.ComponentName.<init>
I've tried checking if the ListView is null and still get the error reports on the Play Store. How do I properly select an item in my list programmatically?
Update to add logcat and the code is virtually identical to the tutorials in the links:

Update 2
And here is the code that is causing the problem:
if (mListFragment.listView != null) {
mListFragment.listView.performItemClick(mListFragment.listView.getAdapter().getView(position, null, null), position, mListFragment.listView.getAdapter().getItemId(position));
}
