Toy not waking up after standby

Once the glyph screen turns black after its timeout, the toy won't wake up when the button is pressed. I would expect that onBind would be triggered as shown in the example project, but it seems that the example also sometimes suffers from this issue.

Possible solutions:

1. Manually rebind when resuming:
   In your app, when the device or UI wakes up, explicitly call bindService() again to re-establish the connection instead of waiting for onBind to trigger automatically.

2. Use a foreground service:
   If you’re depending on background behavior, move the glyph interaction logic to a foreground service. This prevents the connection from being dropped when the system puts the process to sleep.

3. Check lifecycle handling:
   Make sure your binding/unbinding is handled correctly in onResume() and onPause() (or similar lifecycle callbacks) — especially if your toy’s process is being paused when the screen times out.

4. Device-specific quirk:
   Since the example project also shows the same issue, it might be a firmware or system-level limitation. In that case, adding a manual wake or rebind trigger is the most reliable workaround for now.

@lovexanshu that's exactly the issue though - I would expect a callback on either onBind(), onRebind() or something similar, but no callback is coming through. After onUnbind is called, there seems to be no way to wake it back up again except cycling through, which successfully calls onCreate() and onBind() again. The press events are also not being registered when in standby.

After careful further testing it seems that the issue is not in my code but rather that the last active toy in the list suffers from this issue. Moving my toy to be anything but the last in the list solves the issue.
