Are activity contexts / Android applications / services of the same object if they belong to the same application?

Question

Can we assume that getApplicationContext in the application and getContext in AbstractThreadedSyncAdapter returns the same object? How about another case where we get context from activity, service ... all belong to the same application. Thanks.

Activity/Service - ContextWrapper, API, - , . , framework Activity Service, ContextImpl, , . , .
