The technology has improved dramatically over the time. This advancement introduces brilliant approaches to the developers and amazing results to the end users.
One of such advanced service is GCM is Google Cloud Messaging services that was formerly known as Android Cloud to Device Messaging Service (C2DM) in its beta version. This free service is a blessing for the developers as it facilitates developers to allow data transmission to and from the server to the applications running on Android devices. It not only supports data transfers between the server and Android devices (with targeted app), but also allows data transfers between various Android devices connected via GCM.
This service usually employed by every Android Application Development Company could be simply explained as a light-weight message that informs the Android app about the availability of new data that can be fetched from the server. And, it is commonly known as push notification as by the virtue of this service, developers are able to push notifications regarding any app update to all the application users with ease.
The Key features of GCM:
There are numerous benefits of this ultimate service. Some of the most useful features of this service are –
1) It allows the servers to receive the messages from a user’s Android device.
2) In fact, the third party app servers like Java, PHP, etc., can also transfer messages to their respective Android applications.
3) Whether the targeted application is running on an Android device or not, the user will definitely receive the notification. As, the intent broadcast initiates the Android application whenever there is some message on the server. However, it does require certain permissions and broadcast receiver activation.
4) For a device to support GCM service, the Android 2.2 and later OS and Google Play Store is mandatory. And with an emulator, the Google API and Android 2.2 or above will be required.
5) The service simply forwards the message to the Android application. There is no inbuilt UI or other interface provided by the service, so developers can implement a desirable data handling approach. That is, they can either allow data syncing without any notification, post a notification and wait for the response, or offer a custom UI for the same.
6) This service executes by implementing an existing Google service connection. Thus, users are required to create a Google account in their Android device, however, this is not mandatory for the Android 4.0.4 or above devices.
This incredible service has enabled prolific results. It has been used in numerous applications. The Google IO application is one of such applications, whose core functionality is based on this service.
The IO application was launched for every proficient Android Apps Developer prior to Google IO event 2014, to facilitate Google fans and tech-savvy individuals customize their schedule according to the events. And the GCM service has made the application battery efficient. Wondering?
The app enables user’s Android devices to receive auto updates regarding the event. Thus, the targeted devices receive the notifications timely without frequently polling the server.
You can also create an enhanced application by integrating this wonderful Google service; it delivers amazing performance.
