When app is killed, data Notification does not result in a FCMPlugin.onNotification() callback. #295

I'm sending a data notification to wake up the app and download data. I get a callback in FCMPlugin.onNotification() while the app is in foreground or background but not when the app is killed.

Even though the app 'wakes up' upon receiving a notification while the app is killed, I don't get a callback in the plugin. I see this error in the Android Console.

View not ready. SAVED NOTIFICATION: javascript:FCMPlugin.onNotificationReceived({"NOTIF_TITLE":"","priority":"high","wasTapped":false,"NOTIF_BODY":"","NotificationTypeId":"10"})

This error is originating from FCMPlugin:sendPushPayload(). There is a specific check in the code which prevents from making the callback.

if(notificationCallBackReady && gWebView != null){ Log.d(TAG, "\tSent PUSH to view: " + callBack); gWebView.sendJavascript(callBack); }else { Log.d(TAG, "\tView not ready. SAVED NOTIFICATION: " + callBack); lastPush = payload;

I want to do a background data refresh regardless of whether the app is running. How do I implement this?

Hi, I tried the same and for what I understood with this plugin there's no way. The actual way, for android (still didn't have a clue to test it on iOS) is to create a service that runs in background. The main problem is that if you have such a service via so you integrate it in cordova app? If it's my first situation, so even I don't really know how to solve the problem...

The Firebase send a message to android and this will be delivered on status bar. Ok. If (and only if) user tap on notification the app will wake up and "FCMPlugin.onNotification" will be called.

@pierrybos this exact thing you said does not work for me for plugin 2.1.2 version. it only works when app is in the foreground! this is a very simple functionality i guess. for other plugin like onesignal I see an expected behavior. launching app and calling callback if app is killed before, is in the background or is in the foreground. what's the solution?

I find a solution, when I use cordova-plugin-fcm and install cordova-plugin-push too, the background push notifications (on notification click) triggered on ios now.
