The Nearby Messages API allows interested and connected internet users of your app to detect each other when they are in close physical proximity. Yellostack, best mobile app development company in Saudi Arabia is here to help you out, as of how to improve the quality of the Nearby message API. The Nearby Messages API is a publish-subscribe API that lets you pass small binary payloads between internet-connected Android and iOS devices. The devices don’t have to be on the same network, but they do have to be connected to the Internet.
In the first place Nearby uses Bluetooth Low Energy to communicate a unique-in-time pairing code between devices.
Since The server facilitates message exchange between devices that detect the same pairing code. When a device detects a pairing code from a nearby device, it sends the pairing code to the Nearby Messages server for validation, and to check whether there are any messages to deliver for the application’s current set of subscriptions.
Steps to set up an API key:
- Go to the Google Developers Console.
- Create or select a project to register your application with.
- Click Continue to Enable the API.
- On the Credentials page, create a new Android key (and set the API Credentials).
- Note: If you have an existing Android key, you may use that key.
- In the resulting dialog, enter your app’s SHA-1 fingerprint and package name.
Working format of the API nearby messaging :
Let’s say for example there are two individuals who communicate using nearby:
- Device A (the publisher) makes a request to the server to assign a token to a message that the device wants to send. Then, the publisher makes the token detectable to devices nearby.
- Device B (the receiver) pairs its subscription with a token. Then, the receiver sends its token to the publisher and detects the publisher’s token.
- When both devices detect the same token, the message is sent from A to B.
- What is important, the Messages are not exchanged directly between devices; they are sent through Google servers. When one device detects another, it turns to the Google Cloud and says, “Hey! I’ve found a device with this particular token, please give me the message that is associated with it”. Internet connection is required on both devices in order for Nearby Messages to work.
Features of nearby messages API :
- Nearby messages api is known for Broadcasting short messages that nearby devices can detect. Enable forming groups, sharing small amounts of information one way between devices, or broadcasting a resource.
- The unique ranging and cross-platform capabilities of Nearby make it easy to build experiences that seem magical when users are close by. This increases engagement among users who use your Nearby powered features and encourages users to share your app.
Scope and security of the Nearby messages API:
The messages sent with Nearby are public, like a broadcast. For this reason, they are not suitable for transmitting sensitive information; they should rather be treated as the communication initiation stage. If you are still worried that other applications can see what you are transmitting and if your application has to handle messages from other apps, Nearby Message has you covered here. The messages are visible in the scope of the same project in the Google Developers Console. you can have multiple Android and iOS mobile applications associated with the same project.
Best practices to improve the nearby messages API :
- Use the appropriate API for the feature you’re building. Use the API guide to decide which is the best choice.
- Preserve battery life by using Nearby features only when they’re needed. This is because the Nearby APIs may extensively use radio and sensor features, in some cases consuming battery up to 3.5 times faster than normal.
- Use an explicit action to invoke Nearby, such as a button, switch, or special screen. Provide the user with a visual indicator — for example, an animation — to show Nearby is actively sending or receiving content. Use the Nearby logo found at developers.google.com/nearby.
- Make sure the user understands what data will be visible to nearby users of your app before they start using Nearby features.
- Stop using Nearby when your application is not active. See the documentation for more information about how to use or stop using Nearby features.
Now that you know what Nearby Messages is, when to use it, and how simple it is to add it to your application, you might still be wondering how your business can actually benefit from it. The market is relatively fresh for these kinds of apps, hence introducing more apps into the market at this time will shoot up the business.
