Hello! I'm looking for some good design pattern for allowing users to have access to parts of my application.
Essentially my app plays music. I want to allow other apps, widgets, livewallpapers, etc.. to receive currently playing information, current playback time, and allow them to toggle playback and control volume. I want to create a very simple and easy to use API on which developers can use for their apps... My approach would be to provide now playing track information etc by broadcasting this information to registered Broadcast receivers. And for the controls possibly allowing my Service to receive intents to control playback. Few Questions: 1. How bad is it in regards to performance/battery life to broadcast the current playback time? This would happen every 1 second. 2. Is it recommended to provide access to start the Service via an Intent? I guess I would just need to make sure that the service terminates it self when not needed...? 3. Can I tell when a broadcast receiver has been registered? I guess the issue would be that the user might need to populate the "widget" with information even if the service hasn't broadcaster yet the new track... I hope I somewhat make sense if not please ask I'll try to explain better :) Thanks! -Moto -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
