Fixed:
Callbacks_LocationLeak1
Callbacks_LocationLeak2
Callbacks_LocationLeak3
FieldAndObjectSensitivity_FieldSensitivity3
Lifecycle_ActivityLifecycle3
Lifecycle_ServiceLifecycle1

False positive:
Callbacks_MultiHandlers1: Due to object sensitivity (I think)
ArraysAndLists_ArrayAccess1: type imprecision 
ArraysAndLists_ArrayAccess2: type imprecision
ArraysAndLists_ListAccess1: type imprecision
FieldAndObjectSensitivity_FieldSensitivity4: Due to flow sensitivity
FieldAndObjectSensitivity_ObjectSensitivity2: flow sensitivity
GeneralJava_UnreachableCode: We are not whole-program analysis...

True negative: We don't handle implicit flow
GeneralJava_Exceptions4
ImplicitFlows_ImplicitFlow1
ImplicitFlows_ImplicitFlow2
ImplicitFlows_ImplicitFlow3

AndroidSpecific_PrivateDataLeak1: I don't think there is a leak, because 
"sendMessage" isn't called in the life circle of Activity.
