Duplicate Push Notifications #112

Closed abdielou closed 8 years ago

abdielou commented 8 years ago

Hi Arley,

I'm seeing the following behaviour. If re-install an app I will get duplicate Push notifications. This will happen only once. Further Push notifications will be received only once.

And it gets weirder. If I re-install the app 5 consecutive times, then I will receive 5 repeated Push notifications. This will happen only on the first received Push after reinstalling the app. Further Push notifications will be received only once.

Although this is not a terrible issue I have no idea on why it happens.

Any thought.

So now I have a clearer understanding of what is happening. Every time the app is re-installed, a new installation is sent to Parse. So, if I re-install the app 3 times, I will see 3 Push Installations at Parse.

When a Parse Push notification is sent, the device will receive the same Push 3 times. But then, somehow, the Installation at Parse is cleared and only the last one will remain.

Is that Installation clean up done by your PushClient Module?

Hi Abdiel,

No, my PushClient module is not direct integrated to any push notification provider. Maybe it is a feature from Parse: automatic exclude invalid push id.

To avoid duplicates, try to set the "notificationId" attribute to your JSON payload, with an unique or sequential identifier.

Regards,

Arley

@arleyandrada thanks! Setting a notificationId got rid of duplicates.
