My problem is that this is perfectly working and convinient for me to use a modal dialog implemented in a singleton pattern. it will pause the instruction pointer on the Activity and proceed to showing the Dialog under Handlter thread( you can see this on the singleton class) . but im not sure why when i press the "back button" it will crash my application and freeze it. hope somebody can help me out. :(
