About local notification and deep link

Question

Hi, today we tried to show a local notification (PushNotification.localNotification) with deep link attached, but we cannot find an option at https://github.com/zo0r/react-native-push-notification#local-notifications for that. Do we support attaching a link to the local notification? In our case, the notification should appear and open-deep-link-on-click in all cases of app foreground, background and killed. It would be great if somebody can help pointing a way to achieve that.

Thank you and best regards!

Thanks @Niweera for very detailed and helpful answer! We managed to make it work, thanks to your guide. However - just sharing here because the problem was deeper than it looks - because in our code MainActivity is not the launch activity 😂

We didn’t understand why onNotification didn’t work. It turns out we have an activity SplashActivity that lies before everything; after reviewing the code of react-native-push-notification we saw this method:

public Class getMainActivityClass() {
    String packageName = context.getPackageName();
    Intent launchIntent = context.getPackageManager().getLaunchIntentForPackage(packageName);
    String className = launchIntent.getComponent().getClassName();
    try {
        return Class.forName(className);
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
        return null;
    }
}

So clearly this implies that the launch activity is MainActivity. Then we’ve decided to temporary patch react-native-push-notification with the following:

diff --git a/node_modules/react-native-push-notification/android/src/main/java/com/dieam/reactnativepushnotification/modules/RNPushNotificationHelper.java b/node_modules/react-native-push-notification/android/src/main/java/com/dieam/reactnativepushnotification/modules/RNPushNotificationHelper.java

             notification.setStyle(style);
 
-            Intent intent = new Intent(context, intentClass);
+            Intent intent = new Intent(context, Class.forName("com.ourapp.MainActivity"));
             intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
             bundle.putBoolean("foreground", this.isApplicationInForeground());
             bundle.putBoolean("userInteraction", true);

Then onNotification continues to work.

Hi @thongncvn There is a way to avoid this change in the library. It’s documented in the readme and in issues.
