Abstract: The present disclosure provides a method and system to render the push notifications in a communication device of a user. The present disclosure includes a software development kit. The SDK works even when the battery optimization in the communication are turned on. The present disclosure has dedicated server allocations. Servers use firebase cloud messaging APIs to send a notification to the communication device. The FCM servers send the notification downstream to the one or more communication device's operating system to broadcast an intent. This intent is listened by the firebase cloud messaging software development kit installed in a memory of the communication device. The SDK passes the notification payload to a notification service of an application and the notification is rendered. Further, the present disclosure prevents ANR errors and may enable the FCM service in devices that may have not supported FCM service previously.
