Push Plugin for NativeScript
The code for the Push Plugin for NativeScript.
Getting started
-
Create a new NativeScript application
tns create MyApp
or use an existing one.
-
Add the Push Plugin (from NPM). This will install the push plugin in node_module, in the root of the project. When adding a new platform (or using an existing one) the plugin will be added there as well. Go to the application folder and add the push plugin:
tns plugin add nativescript-push-notifications
Android
-
Go to the application folder and add the Android platform to the application
tns platform add android
-
Add Google Play Services, as GCM is part of it. It's present in the android-sdk. Add it like this (NOTE: your path may be different, it depends on the installation path of the Android SDK):
tns library add android C:\Users\your_user_name\AppData\Local\Android\android-sdk\extras\google\google_play_services\libproject\google-play-services_lib\libs
-
Add sample code in app/main-view-model.js in the function HelloWorldModel() like this one to subscribe and receive messages (Enter your google project number in the options of the register method):
var pushPlugin = require("nativescript-push-notifications");
var self = this;
pushPlugin.register({ senderID: '<ENTER_YOUR_PROJECT_NUMBER>' }, function (data){
self.set("message", "" + JSON.stringify(data));
}, function() { });
pushPlugin.onMessageReceived(function callback(data) {
self.set("message", "" + JSON.stringify(data));
});
-
Attach your phone to the PC, ensure "adb devices" command lists it and run the app on the phone:
tns run android
-
The access token is written in the console and in the message area, after subscribing (Look for ObtainTokenThread log record). When sending a notification, the message below the TAP button should be changed with the message received.
iOS
-
Edit the package.json file in the root of application, by changing the bundle identifier to match the one from your Push Certificate. For example:
"id": "com.telerik.PushNotificationApp"
-
Go to the application folder and add the iOS platform to the application
tns platform add ios
-
Add sample code in app/main-view-model.js in the function HelloWorldModel() like this one to subscribe and receive messages (Enter your google project id in the options of the register method):
var pushPlugin = require("nativescript-push-notifications");
var self = this;
var iosSettings = {
badge: true,
sound: true,
alert: true,
interactiveSettings: {
actions: [{
identifier: 'READ_IDENTIFIER',
title: 'Read',
activationMode: "foreground",
destructive: false,
authenticationRequired: true
}, {
identifier: 'CANCEL_IDENTIFIER',
title: 'Cancel',
activationMode: "foreground",
destructive: true,
authenticationRequired: true
}],
categories: [{
identifier: 'READ_CATEGORY',
actionsForDefaultContext: ['READ_IDENTIFIER', 'CANCEL_IDENTIFIER'],
actionsForMinimalContext: ['READ_IDENTIFIER', 'CANCEL_IDENTIFIER']
}]
},
notificationCallbackIOS: function (data) {
self.set("message", "" + JSON.stringify(data));
}
};
pushPlugin.register(iosSettings, function (data) {
self.set("message", "" + JSON.stringify(data));
if(iosSettings.interactiveSettings) {
pushPlugin.registerUserNotificationSettings(function() {
alert('Successfully registered for interactive push.');
}, function(err) {
alert('Error registering for interactive push: ' + JSON.stringify(err));
});
}
}, function() { });
-
Run the code
tns run ios
-
Send notifications
API
var pushPlugin = require('nativescript-push-notifications');
- register - use to subscribe device for push notifications
register(settings, successCallback, errorCallback)
var settings = {
senderID: '<ENTER_YOUR_PROJECT_NUMBER>',
notificationCallbackAndroid: function(message) {
alert(JSON.stringify(message));
},
badge: true,
sound: true,
alert: true,
notificationCallbackIOS: function(message) {
alert(JSON.stringify(message));
}
};
pushPlugin.register(settings,
function(token) {
if(pushPlugin.onMessageReceived) {
pushPlugin.onMessageReceived(settings.notificationCallbackAndroid);
}
alert('Device registered successfully');
},
function(error){
alert(error.message);
}
);
- unregister - use to unsubscribe from Push Notifications
unregister(successCallback, errorCallback, settings)
pushPlugin.unregister(
function(){
alert('Device unregistered successfully');
},
function(error){
alert(error.message);
},
settings
);
- Register for interactive push notifications (iOS >= 8.0) - in order to handle interacitve notifications, you have to pass additional settings while registering your device. The message object in the notificationCallbackIOS will contain a property with the value of the identifier.
register(settings, successCallback, errorCallback)
var settings = {
badge: true,
sound: true,
alert: true,
interactiveSettings: {
actions: [{
identifier: 'READ_IDENTIFIER',
title: 'Read',
activationMode: "foreground",
destructive: false,
authenticationRequired: true
}, {
identifier: 'CANCEL_IDENTIFIER',
title: 'Cancel',
activationMode: "foreground",
destructive: true,
authenticationRequired: true
}],
categories: [{
identifier: 'READ_CATEGORY',
actionsForDefaultContext: ['READ_IDENTIFIER', 'CANCEL_IDENTIFIER'],
actionsForMinimalContext: ['READ_IDENTIFIER', 'CANCEL_IDENTIFIER']
}]
},
notificationCallbackIOS: function(message) {
alert(JSON.stringify(message));
}
};
pushPlugin.register(settings,
function(token){
if(pushPlugin.onMessageReceived) {
pushPlugin.onMessageReceived(settings.notificationCallbackAndroid);
}
if(settings.interactiveSettings) {
pushPlugin.registerUserNotificationSettings(function() {
alert('Successfully registered for interactive push.');
}, function(err) {
alert('Error registering for interactive push: ' + JSON.stringify(err));
});
}
},
function(error){
alert(error.message);
}
);
- areNotificationsEnabled - check if the notifications for the device are enabled. Returns true/false. Applicable only for iOS, for Android always returns true.
areNotificationsEnabled(callback)
pushPlugin.areNotificationsEnabled(function(areEnabled) {
alert('Are Notifications enabled: ' + areEnabled);
});
- onTokenRefresh - Android only, subscribe for the token refresh event (Used to obtain the new token in cases where google revoke the old one)
onTokenRefresh(callback)
pushPlugin.onTokenRefresh(function(token){
alert(token);
});
Troubleshooting
In case the application doesn't work as expected. Here are some things you can verify
Android
- Ensure that the AndroindManifest.xml located at platforms\android contains the following snippets for registering the GCM listener:
<activity android:name="com.telerik.pushplugin.PushHandlerActivity"/>
<receiver
android:name="com.google.android.gms.gcm.GcmReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.pushApp.gcm" />
</intent-filter>
</receiver>
<service
android:name="com.telerik.pushplugin.PushPlugin"
android:exported="false" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
- Ensure that the AndroindManifest.xml located at platforms\android contains the following permissions for push notifications:
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
iOS
- Error "Error registering: no valid 'aps-environment' entitlement string found for application" - this means that the certificates are not correctly set in the xcodeproject. Open the xcodeproject, fix them and you can even run the application from xcode to verify it's setup correctly. The bundle identifier in xcode should be the same as the "id" in the package.json file in the root of the project.
Using with Telerik Backend Services
