Sometimes button callbacks are empty for a few minutes #25
Description
I've successfully integrated the Android SDK into my app, and can use the Flic button to trigger actions in my app.
The only problem is that sometimes when I launch my app, button callbacks aren't called until after the app has been running for a few minutes. By adding breakpoints to FlicManager.java, I can see that onButtonSingleOrDoubleClickOrHold is called, but button.callbacks is empty. That means onButtonSingleOrDoubleClickOrHold in my FlicBroadcastReceiver subclass isn't called.
If I don't do anything, and wait a few minutes, eventually all the button presses I sent during that time will come through and onButtonSingleOrDoubleClickOrHold in my FlicBroadcastReceiver subclass will be called for each missed button press -- but the timeDiff is 0 for all those events, so I can't ignore them.
Other times when I launch the app, it behaves correctly right away. Have you seen this?
I'm using Android 8.1.0 and the latest version of the SDK downloaded yesterday.
