apps auto close when too much marker on certain angle

[GoogleCodeExporter]

Sorry, i really need some help here, after i have added for like around 10 icon 
marker in LocalDataSource.java, when i launched the apps, i move my camera to 
the icon, and i hold on the position of my camera for like 10second and looking 
on the icon (8 of them are sticking together since i set the collisionDetection 
to "false"), the apps will auto-close or exit without any crash alert like 
("unfortunately blabla... has stopped), it just auto close the app without any 
notification, and there is 1 thing i found out is when i only put 1 or 2 
iconmarker or i move the camera to angle that dont have any marker, this 
problem is solved (i mean the apps wont force-close)..... Just let me know if u 
need any of my files... thank you

What is the expected output? What do you see instead?
i hope the apps will not auto-close when i put up more than 10 icon marker

What version of the product are you using? On what operating system?
i am using galaxy nexus 4.2.2 jelly bean and eclipse

Please provide any additional information below.
I am kinda new to augmented reality, so really need help on fixing this bug.... 
i have been trying to solve it for 2 weeks...
