Strict Mode Error on Android 5.0 in Nexus 7

My app is running well on version below 5. But when i run it on Nexus 7 with version 5, it crashes with following error msg

SlidingMenu and Android-PullToRefresh libraries conflict

I am currently using 2 libraries in my Android project:
SlidingMenu: https://github.com/jfeinstein10/SlidingMenu
Android-PullToRefresh: https://github.com/chrisbanes/Android-PullToRefresh
With Android 4.x everything works right, but in Android 2.x I get a StackOverflow Exception.
I am not sure if it is an Android version issue or a hardware issue.
This is the log of the exception:

Can somebody help me to solve the issue?
Thank you!

You generally see this error when you have too many nested views - a problem which is exacerbated on older versions of Android.
However, I have also noticed that the slidingmenu lib can cause this on older versions of android (3.X or earlier). I used to see this error all the time and it was originating from the slidingmenu code - my own views were only nested 10-15 deep (not great, but not disastrous). I switched to the menu-drawer library https://github.com/SimonVT/android-menudrawer and the error disappeared.
Things to try...
Fire up the android device monitor or hierarchy viewer (http://developer.android.com/tools/debugging/debugging-ui.html) and have a look at your layouts. If there are any views deeper than say, 15-20 you might want to have a look at optimizing your layouts.
Try swapping out your sliding-menu lib for either google's own (in the support lib) or the one I mentioned above (which may be easier to swap as it follows a similar design to slidingmenu - it took me about an hour).
Good luck!

StackOverflow exception in Fragments

I have a tabhost with 5 tabs which are FragmentActivity. One of them contains a sequence of 7 views. I think that each is a fragment, but when I get to fragment 7 the app explodes.
When I press the continue button in each fragment I start a new fragment in this way:
MyFragment newFragment = new MyFragment ();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.publish_map_direction, newFragment);
transaction.addToBackStack(null);
transaction.commit();
This is the error:

Should I structure my app in a different way?

Yes.
I would recommend using just fragments, instead of nesting fragment activities inside the tab host. I usually create a tab bar and just have a frame layout below it that I put a fragment in. then i replace fragments depending on what gets clicked. That should definitely help, because I think you just have too many things going at the same time.

ActionBarSherlock for Android causing StackOverflowError

I integrated ActionBarSherlock into my Android application. It is mostly working well, with one serious exception...
When running specifically on API Level 10 (which corresponds to Android 2.3.3), and only on that version, a StackOverflowError (shown below) is happening at a certain point when the user navigates between two particular activities. The call stack reveals that this error happens entirely within the Android framework, independent of my custom code.
The only reason I know it is related to ActionBarSherlock is that the error doesn't happen if I revert my changes to the activity classes so that they again inherit from the standard Activity base class instead of SherlockActivity, and revert to a non-Sherlock theme.

I just encountered a similar error when invalidateOptionsMenu() was being called twice in very quick succession (in onResume, and then in onPrepareOptionsMenu).
Once I removed the invalidateOptionsMenu() calls from onPrepareOptionsMenu, the issue went away. Maybe this isn't what's happening in your situation, but just thought I'd offer it as a possible solution.

The UI thread stack size on Android 2.x is smaller than Android 4.x. This means older versions are more prone to StackOverflowErrors. This explains why you only experience this on an older version.
The problem with ABS is that it automatically adds a few nested views to your layout (the main layout which holds the action bar). You can see these extra views by using Hierarchy Viewer.
If you already had a deep layout with many nested views, adding ABS probably added the extra views that filled up your stack.
What I suggest is that you simplify your layout and remove some of your extra views. There are a few tips on how to optimize layouts in the Android Developer Blog (by Romain Guy). If you save about 2-3 views, it should compensate on what ABS added and you should be fine.

Sounds like your device does not have a camera (emulator!) or that you dont have the appropriate permissions defined in your manifest.
android.permission.CAMERA

I think the problem is in your device, because the tutorial has ask you to add the permission. Edit your AVD and add camera support in hardware
