Yeah, I think it is broken. The observable can write the data to console, but the template value doesn't get updated.
Using NgZone and zone.run() also allows the template to be updated.
Which is the better way to update the display...
NgZone, or ChangeDetectorRef ??
Like that, i'm using android studio with native code for example.
Please show some code for implementation.
Yes you will have to write you own API. Depending on the technology(pHp, nodeJs etc) there variant packages for them.
For nodeJs server side APP check this
https://www.npmjs.com/package/fcm-nodeFor Laravel project
https://github.com/turbo124/laravel-push-notificationYou can google for other technology packages. I hope this helps.
const options: PushOptions = {
android: {
senderID: 'Here is my send id',
sound: true,
vibrate: true,
clearBadge: true,
icon: 'icon',
clearNotifications: true,
},
ios: {
alert: true,
badge: true,
sound: true,
clearBadge: true
},
windows: {}
};
const pushObject: PushObject = this.push.init(options);
pushObject.on('notification').subscribe((notification: any) => {
console.log('message', notification.message);
let self = this;
if (notification.additionalData.foreground) {
// if application open, show popup
let confirmAlert = this.alertCtrl.create({
title: 'Notification...',
message: JSON.stringify(notification),
buttons: [{
text: 'Ignore',
role: 'cancel'
}, {
text: 'View',
handler: () => {
//TODO: Your logic here
//self.nav.push(DetailsPage, {message: data.message});
}
}]
});
confirmAlert.present();
} else {
//if user NOT using app and push notification comes
//TODO: Your logic on click of push notification directly
// this.nav.push(Contact, { message: notification.message });
}
});
pushObject.on('registration').subscribe((registration: any) =>
{
console.log("Registration Id : " + registration);
});
pushObject.on('error').subscribe((error: any) => {
console.log("Error : " + error);
});I am sending push messages from Firebase Cloud Messaging notifications.
I am receiving messages but I don't know how to play custom sound there.
I have placed mp3 Preformatted textsound file in res>>raw folder but nothing works.
I would recommend you check on this, I hope it helps.
https://github.com/phonegap/phonegap-plugin-push/blob/master/docs/PAYLOAD.md#soundThis is a big issue and i am unable stuck 
I deleted the android platform and reinstalled it -- didn't work
when do i get the error?
its a button call and behind the call i call this lifted from the ionicframework site:
import { Camera, CameraOptions } from '@ionic-native/camera'
...
launchCamera() {
const options: CameraOptions = {
quality: 100,
destinationType: this.camera.DestinationType.DATA_URL,
encodingType: this.camera.EncodingType.JPEG,
mediaType: this.camera.MediaType.PICTURE
}
this.camera.getPicture(options).then((imageData) => {
// imageData is either a base64 encoded string or a file URI
// If it's base64:
let base64Image = 'data:image/jpeg;base64,' + imageData;
}, (err) => {
// Handle error
});
}Now i cant event reinstall the Cordova Camera plugin. i am following what we have in the following post
i keep getting this error
"Error: Cannot find plugin.xml for plugin "cordova-plugin-camera". Please try adding it again."
I dont know what is this plugin.xml and what to do with it when i find it
So stuck.. will appreciate all help i can get 
The last time I had to downgrade my systems cordova to 6.0.5. then reinstall the camera plugin.
npm install cordova@6.0.5I hope it works in your case
I already read that documents. I have fixed the issue. I was using old version of push plugin.
Anyways, Thank you so much.
Who is causing it? I don't know.
Angular is running is development mode could be the guy causing it.
Click the bundle.js:4776 to see the code on that line, perhaps that would give you an insight.
it is the same issue with every project.
