没有调用onPause的整理活动

Question

I am finishing my current activity using finish(). This is calling onPause automatically. I want to finish activity without onPause being called. My activity is running a song service so i want song to stop when app is in background but dont want it to stop when user goes from one activity into another in my app. I cant do stopService and startService in between activities because then there is a momentary lag in between the sounds.

Answer 1

A Service is an application component that can perform long-running operations in the background and does not provide a user interface

google docs

The background Service is agnostic of which Activity is running or any discontinuity between them.

The two types, "bound" and "started" are supposed to have different persistence characteristics but in practice (not stress testing) I find the bound Service does not clobbered for lack of system memory and is much easier to implement (despite tutorials claiming otherwise). It uses some IPC abstraction that appears as though it is being directly invoked from the Activity . The same can't be said of the "started" variety (unless it is also bound) which is IMO a closer approximation to the traditional service I would associate with web-servers (or anything that is already going to be experiencing not insignificant delays- such as due to network transmission).

(Lecture over) I see you are calling finish() . You need some way to shut down the Service from your Activity . Just make sure to branch aways from doing so when not intended. Code would be helpful but I can assure you this is how media players work.
