Our focus has been on iOS and I realise that I should have stated this
in my mail message. Apologies.
Currently IOS does not start our app when the iPhone receives an
AeroGear notification with content-available = 1 in it AND (the app has
not been started OR is in the background). Basically we start the iOS
app, send a notification to check it works in the foreground. We then
swipe up to stop the app, send a new notification down, the new
notification is displayed BUT the AeroGear call back to handle the
notification is not called. If there is a a magic combination of alert
and content-available flags to make this happen we’d be happy to put
them in our code but we cannot see anything happening at all. We have
not checked Android for this behaviour, as for technical reasons we
<cough> I <cough> broke our last Nexus 5 phone on Friday and have not
replaced it yet. We’ll have a new one tomorrow.
What we have to do at the moment is check to see if the app has received
the silent notification as it will then make a callback to our server,
if there has been no callback wishing 60 secs, our server sends a full
notification with an alert in that is displayed by the device. The
downside to this method is that we lose the ability to clean out old
notifications using the silent notification AND a local cordova plugin,
Our thinking is that both iOS and Android should start up in the
background when they receive a notification with an empty alert AND a
content-available = 1 flag AND the app is not running. We could use
Apple background-fetch to get 30 secs of processing and then shutdown
again. Unclear as to the system on Android.
We have also now seen that Apple very aggressively moves Apps from a
background state to a suspended state after not very long, which also
means that the app doesn’t respond to content-available = 1 flags. We
haven’t worked out how long this interval is, but its not hours. This
actually underscores the importance of handling the content-available =
1 flag working when apps are suspended or not started.
We are really starting to dislike Apples notification implementation.
The email address is list specific, we have our own mail servers so its
easy to simply use specific emails which we can then track. Its easy to
block as well if they get spammed.
