Your XML is probably too complicated and giving additional commands for drawing may be blocking you.
If you have too many nested layout views or if you have too many methods which have recursive calls it is normal that you will see java.lang.StackOverflowError.
Check out Android Developers blog to see how to ideally optimise your complex Layouts.
Also don't forget to check CommonsWare answer in the following topic about number of nested layouts:

I know it says the error is at line 16 in the xml but what xml file theres 30 xml files so if you have any ideas please let me know
The device is a Samsung Galaxy Tab S running 4.4.2
any help would be awesome
Thanks in advance

I figured it out! the xml in question is located in: res/layout-sw720p/search_bar.xml
on line 16 you need to add the following code:
android:layout_width="match_parent"
android:layout_height="match_parent"
This fixed the crashing issue I hope this helps anyone else who is having this issue!

Why m I getting this error any idea?

Your UI View tree is too deep. addFocusables is recursive (obviously) into the View layout tree and Android has a fairly limited stack size. Change your layout to do less nesting and more of a flat layout. You may need to write a custom layout to get the layout you want without nesting.

Any help is Appreciated...

you have used this code.
final List<ObjectiveWiseQuestion> QuestionWiseProfile1= db.getOneQuestion(examId);
but you have not opened db before. So it is getting null.
ok write
tts = new TextToSpeech(this, this);
before you use tts object.

The tts object is not initialized. Hence you get a null pointer exception there.

I have an andengine program that works on one development machine but not another?

For reasons with which I won't bore you, I have to change development computers, and for the life of me I can't get my project to work on the second machine.
I have one library which is a .jar file which both machine have access to. But the program works fine on machine A but on machine B I get the errors below. At first I thought check the manifest, but, exactly the same project works fine on Machine A. So it must be something wrong with my development environment on B. Right? I can't think what it might be. I've got more apis on B than A.

Sounds like a dodgy install on the second device to me, since one of the classes being called cant be found. Have you tried reinstalling?
edit: Sorry for sounding like someone from a tech support line...
