Basically moved code out of ControlCenter to a separate class. Also provides
change events when the device list has changed, or changes to the device
state have occurred.
- localstorage is now cleared at every launch: this prevents some clay configuration pages to send back to the watch a number of keys that were set by other configuration pages
- only execute JS on document ready: this prevents some race conditions
- added dummy getTimelineToken function to Pebble JS object
- corrected (hopefully!) a few logic errors in the JS code (this referenced where it wasn't)
- refactored the steps visualization in JS
- lifecycle changes to the java activity: now the configuration page gets closed as soon as the settings have been sent, and there is only one instance of it
- Also send duration if "duration" extra is present
- If "playing" and "postion" extras are present send a music state update
treat previous state and current state as equal if position delta is <=2 seconds
(Neccessary for some players which update every second - the pebble however counts by itself)
Since Android 5.0, media players can have interactive notifications that
reside in the notification area, and offer up to 5 control buttons
(play/pause, next, previous, etc), and information about the currentlu
playing media file.
We use these notifications to get information about the currently
playing media file such as:
- artist
- track (title)
- album
- duration (length of the media file)
- play state (playing, paused, stopped)
- position
- play rate (how fast is the media file being played)
We then send this information up to the device.
On Pebble, the music app will display the title and the artist, as
well as a progress bar showing the current position. The progress bar is
animated when the media file is being played, and if it is being paused,
it displays a pause symbol.
This code will be skipped when GadgetBridge is run on a device with
Android version older than 5.0 (lollipop).
This commit contains the infrastructure needed for the
NotificationHandler to send music state information to the device. That
is, it introduces a call onSetMusicState(MusicStateSpec stateSpec), that
in turn sets up an intent to the service, which will then call the
encodeSetMusicState() function of the device. encodeSetMusicState is
available for pebble only. There are empty stubs for other devices.
encodeSetMusicState will be accessible on its own. If it was used to set
the music state, a call to encodeSetMusicInfo must not reset this info
arbitrarily.
PocketCasts tells about its current media state via notifications. This
patch tries to parse incoming notifications from PocketCasts and if
successful tells the device about it. Currently supported are track and
artist.
