Thread runtime exception

synchronized (this.childrenGroupsLock) {
            for (int i = 0; i < numGroups; i++) {
                suspendCurrent |= this.childrenGroups[i].suspendHelper();
            }
        }
return suspendCurrent;

This is the thread that force closes my application(any android application). I dunno how to handle it.

Can anyone please help me?

The application just force closes after it reaches this point.
