Push Notifications
Push Notifications
•
Example
• Select device
• Send message • Get notified
Push Notifications
• Subscribe to Messaging Service
• Receive token
• Register with Enterprise app
• Enterprise app Pushes message to Messaging Service
• Messaging Service delegates message to device(s)
Push Notification
Setup GCM
• Google Cloud Project
• Google Cloud Messaging API is
enabled
• API key
Setup APNS
• iOS Developer account
• App Id and Provisioning profile
– Make sure to check the Push Notification Service when you create the new App Id
• SSL Certificate
Create a Provider Application
Prepare Provider Application
• Add gcm-server.jar (for GCMS)
• Add javaPNS.jar (for APNS)
Code Behind the Button
• Class to push a message to a device.
public void pushNow(ActionEvent actionEvent) {
….. Logic to get selected row…
String target = (String)curr.getAttribute("DeviceToken");
String type = (String)curr.getAttribute("DeviceType");
if (type.equalsIgnoreCase("Android")) {
pushMsgAmdroid(target, this.message);
} else {
pushMsgIos(target, this.message);
}
Server Side for Android
• Sending the message
String sound = "default";
Message message =
new Message.Builder()
.delayWhileIdle(true)
.addData("alert", msg)
.addData("sound",sound)
.addData("FeatureName", "Sessions")
.addData("SessionId", "12")
.build();
Result result;
try {
result = sender.sendNoRetry(message, regId);
}
Server Side for iOS
• Sending the message
/* Build a blank payload to customize */
PushNotificationPayload payload = PushNotificationPayload.complex();
/* Custom the payload */
payload.addAlert(msg);
payload.addBadge(1);
payload.addCustomDictionary("FeatureName", "Sessions");
payload.addCustomDictionary("SessionId", "12");
Push.payload(payload, KEYSTORE_LOCATION, KEYSTORE_PASSWORD, false,
target);
Preparing ADF Mobile
• Register Application Life Cycle Listener
• LifeCycleListener must implement oracle.adfmf.application.PushNotificationConfig interface.
– This interface provides the registration configuration for push notifications
ApplicationLifeCycleListener
• ApplicationLifeCycleListener
– In the Start() Method create a new PushNotificationListener()
public void start() {
// Add code here...
EventSource evtSource =
EventSourceFactory.getEventSource(
NativePushNotificationEventSource.
NATIVE_PUSH_NOTIFICATION_REMOTE_EVENT_SOURCE_NAME);
evtSource.addListener(new PushNotificationListener());
}
The PushNotificationListener
• In the PushNotificationListener
– OnOpen() // receive token
– OnMessage() // handle notification
– OnError()
public void onOpen(String token) {
// Invoked during the Push Notification registration process.
// The parameter "token" contains the token received from APNs or GCMs
// that uniquely identifies a specific device-application combination.
ValueExpression ve = AdfmfJavaUtilities.getValueExpression(
"#{applicationScope.deviceToken}", String.class);
if (token != null){
ve.setValue(AdfmfJavaUtilities.getAdfELContext(), token);
}
else{
ve.setValue(AdfmfJavaUtilities.getAdfELContext(), "dummy Token");
}
}
Token Registration
• Use a webservice to send the Token to the provider Application
• Provider stores token and uses it when sending notifications (remember the “code behind the button”
public void pushNow(ActionEvent actionEvent) {
….. Logic to get selected row…
String target = (String)curr.getAttribute("DeviceToken");
String type = (String)curr.getAttribute("DeviceType");
if (type.equalsIgnoreCase("Android")) {
pushMsgAmdroid(target, this.message);
} else {
pushMsgIos(target, this.message);
}
All is there.
• Cloud Services are setup
• Provider app is created
• Device Token can be sent to and stored at provider app
• LETS PUSH ! And work with the notification
Push Notifications
•
onMessage()Working with the Notification
public void onMessage(Event event) {
AdfELContext adfELContext = AdfmfJavaUtilities.getAdfELContext();
JSONBeanSerializationHelper jsonHelper =
new JSONBeanSerializationHelper();
try {PayloadServiceResponse serviceResponse =
(PayloadServiceResponse)jsonHelper.fromJSON(
PayloadServiceResponse.class, event.getPayload());
ValueExpression notificationPayloadBinding =
AdfmfJavaUtilities.getValueExpression(
"#{applicationScope.notificationSessionId}", String.class);
notificationPayloadBinding.setValue(
AdfmfJavaUtilities.getAdfELContext()
, serviceResponse.getSessionId());
AdfmfContainerUtilities.gotoFeature(
"com.tamcapp.mobilebook.ses.ConferenceSessions");
}
Badging
// also, lets decrease the application icon badge by one
int currentBadge =
AdfmfContainerUtilities.getApplicationIconBadgeNumber();
if (currentBadge > 0) {
AdfmfContainerUtilities.setApplicationIconBadgeNumber(
currentBadge - 1);
}
In the feature…
• Use FeatureLifeCycleListener
– Activate() Method
public void activate() {
Boolean notified =
(Boolean)AdfmfJavaUtilities.evaluateELExpression(
"#{applicationScope.notified}");
if(notified.booleanValue({
AdfmfContainerUtilities.invokeContainerJavaScriptFunction(
AdfmfJavaUtilities.getFeatureName(),
"adf.mf.api.amx.doNavigation”,
new Object[] { "featureActivated" });}
}
DEMO
Push Notification - Summary
• Configuration can be complicated (Especially on iOS)
• Listeners, Listeners, Listeners
– ApplicationLifeCycle
– PushNotification
– FeatureLifeCycle
• Send Notification (optional with Payload)
• onMessage()
– Get Payload
– Call feature
• In Feature
– Work with payload
