Ok so I've got a map activity which displays some pins. I have a thread which runs in the background, it will periodically generate new pins to place on this map activity. I guess I can communicate between the 2 via a Handler.
>From the map activity, the user may create a new Activity to enter some text let's say. Now the map activity is 'paused', but the background thread is still trying to post messages to its Handler.Will the Handler respond at all, or will messages begin queuing up until the user ends the text activity, returning back to the map activity?
