Nearby Service has a technological edge in the following gaming scenarios:
Uses Bluetooth and Wi-Fi to discover devices. After integrating Nearby Service, your game can automatically search for nearby users who are also in the game without manual intervention.
Selects the best networking and transmission modes automatically. Nearby Service supports P2P, star, and mesh topologies and allows devices to connect to each other through Wi-Fi P2P without connecting to the same AP.
Uses Huawei-developed transmission protocols featuring high bandwidth, low latency, and high stability and reliability to transmit data.
App Development
An open-source game named Snake Land on GitHub is available for us to implement network communications using Nearby Service to support multi-player gaming. Snake Land originally uses the open-source framework KryoNet to implement the network communication layer. KryoNet supports only interconnection between mobile phones connected to the same router. After Nearby Service is integrated, nearby mobile phones can connect to each other unconditionally.
Getting Started
To integrate HUAWEI Nearby Service, you must complete the following preparations:
Configure app information in AppGallery Connect.
Enable HUAWEI Nearby Service.
Integrate the HMS Core SDK.
Configure obfuscation scripts.
For details, please refer to Getting Started.
How Can I Use Nearby Service
First, let's compare the APIs of KryoNet and Nearby Service.
API functions of Nearby Service and KryoNet are the same. Therefore, we only need to replace the APIs of KryoNet with those of Nearby Service and convert parameters based on the parameter type differences.
Permission Application
Nearby Service involves operations such as Bluetooth discovery and Wi-Fi hotspot creation. Therefore, you need to apply for some permissions from the user.
The sample code is as follows:
Code:
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Building, Loading, and Debugging the App
After configuring the previous code, build your app, generate an APK file, and install it on the prepared phone running Android 8 or later for debugging. For details about the development procedure, please refer to Codelab.
Testing Your App
One party taps Create a Game, and the other party taps Join a Game to start mutual discovery. After one another is discovered, tap GO! to start the game. Swipe on the screen to control the direction of the green snake and get more food. The snake will fail if its head hits an obstacle.

HMS Nearby Services vs. GMS Nearby Connection
When using Huawei's nearby service for file transfer, users are able to achieve up to 50mbps file transfer speed. This is faster than the GMS nearby connect service, which will max out at 40mbps. This faster data transfer speed is made possible by Huawei's proprietary nStack technology.
Faster speeds mean that the HMS solution will be better for creating apps that allow users to transfer large file sizes. Sending movies, music, documents, or other large files will now be as easy as transferring them to a nearby phone. A good example of an app that benefits from nearby service is Zapya. This popular file transfer app uses HMS nearby services to let you send large files to phones that are close by. Using the app, you'll be able to transfer a 3GB file in only 1 minute. You can rely on efficient and secure file transfers.
File transfer speed isn't the only area where HMS is able to out-perform GMS. The node discovery speeds also come into play here. This is where a user will scan for a nearby phone, and wait for results. Nearby service has faster discovery time based on Huawei-developed protocols.
