Question

I am working on Google Maps in Android. It requests to the server for some content to be showed on markers, now I want to kill the connection of pending requests or all requests when user pans the map.

Answer 1

Close the underlying InputStream this will close the connection as well.

Regaring submitting requests to something (such as to your connection) and then cancelling the requests you can check ExecutorService interface. It has execute(), shutdown() and awaitTermination()
