I have a service that creates, plays and handles a mediaplayer (just audio), yet I have a seekbar in the main activity that I want to, naturally, show the progress of the audio file and allow the user to seek to various positions.
What I'm having a hell of a time figuring out is: what would be the best or proper way to connect the seekbar in the UI to the mediaplayer in the service?

You can also try Otto from Square
You just need to create a class SeekBarSyncEvent.java
, put the parameters you need in there:
Then you can initialize the seekbar from the activity by posting an event from the bus with your SeekBarSyncEvent
class in the onPrepared()
method from your service.
Finally create the @Subscribe
method on your activity so it calls to your seekBarUpdate()
method.
This should work fine, nice and easy to maintain.

Here is how I would do this:
Bind to service that plays audio. The interface that server returns in onBind
should have getCurrentPos()
and getDuration()
functions.
In your Activity's onCreate
bind to service
onResume
use Handler
's postDelayed
function to start updates.onPause
stop all callbacks posted via postDelayed
function.postDelayed
run boundService.getCurrentPos()
and boundService.getDuration()
and update the seekbar appropriately.To summarize, you should use service binding and handler for recurring updates.
Handler
for periodic updates read this question: Repeat a task with a time delay?Upvotes: 4

Try taking a look at MediaController to see if it's of use to you.
