How does Kirin OS interconnect with other devices and operating systems?

Kirin Operating System (HarmonyOS) is a full-scenario distributed operating system launched by Huawei. As a new operating system, Kirin not only supports running on Huawei devices, but can also interconnect with other devices and operating systems. This article will explore how Kirin OS achieves interconnection with other devices and operating systems, and give some code examples.

First of all, Kirin OS supports multiple communication protocols, such as Bluetooth, Wi-Fi, NFC, etc., which makes it easy to communicate with other devices. By using these communication protocols, Kirin OS can perform data transmission, file sharing and other operations with other devices. The following is a sample code that uses Bluetooth for data transmission:

import com.huawei.harmonyos.bluetooth.btadapter.BluetoothAdapter;
import com.huawei.harmonyos.bluetooth.btle.api.BleCentralManager;
import com.huawei.harmonyos.bluetooth.btle.api.BleGatt;
import com.huawei.harmonyos.bluetooth.btle.api.BlePeripheralManager;
import com.huawei.harmonyos.bluetooth.btle.api.BlePeripheralManagerCallback;

public class BluetoothDemo {
    private BluetoothAdapter bluetoothAdapter;

    public void connectToBluetoothDevice(String deviceAddress) {
        bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
        BleCentralManager centralManager = bluetoothAdapter.getBleCentralManager();
        BleGatt gatt = centralManager.connectGatt(deviceAddress);
        gatt.setGattCallback(new BlePeripheralManagerCallback() {
            @Override
            public void onConnectionStateChange(int newState, int status) {
                if (newState == BlePeripheralManagerCallback.STATE_CONNECTED) {
                    // 连接成功，可以进行数据传输等操作
                } else if (newState == BlePeripheralManagerCallback.STATE_DISCONNECTED) {
                    // 连接断开
                }
            }

            @Override
            public void onCharacteristicChanged(String uuid, byte[] value) {
                // 接收到特征值变化的回调方法，可以处理接收到的数据
            }
        });
    }
}

In addition to communicating with other devices, Kirin OS also supports interconnection with other operating systems. Kirin operating system is designed based on the microkernel architecture. Applications of other operating systems can be run on Kirin through virtualization technology to achieve seamless connection between different operating systems. The following is a sample code for running an Android application on Kirin operating system:

import android.content.Context;
import android.content.Intent;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageManager;
import android.os.Bundle;

public class AndroidDemo {
    public void launchAndroidApp(Context context, String packageName, String className) {
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);
        intent.setClassName(packageName, className);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(intent);
    }

    public void getApplicationMetaData(Context context, String packageName) {
        try {
            ApplicationInfo appInfo = context.getPackageManager().getApplicationInfo(packageName, 
                PackageManager.GET_META_DATA);
            Bundle metaData = appInfo.metaData;
            // 获取其他操作系统应用程序的元数据
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
    }
}

As can be seen from the above code example, Kirin operating system can interconnect with other devices through various communication protocols, and can also communicate through virtual technology to integrate with other operating systems. This brings more convenience to users and more possibilities for application development. I believe that with the development of Kirin operating system, its interconnection functions with other devices and operating systems will become increasingly powerful.
