2、实现

本案例DEMO的实现主要借鉴了网上现有的资料: https://blog.csdn.net/chenzhengfeng/article/details/119868210

并在此基础上进行了扩展、封装,希望能帮到有需要的小伙伴们~

2.1、鸿蒙工具类封装 HarmonyUtils

import android.text.TextUtils;
import java.lang.reflect.Method;

/**

public class HarmonyUtils {
    /**
     * 是否为鸿蒙系统
     *
     * @return true为鸿蒙系统
     */
    public static boolean isHarmonyOs() {
        try {
            Class<?> buildExClass = Class.forName("com.huawei.system.BuildEx");
            Object osBrand = buildExClass.getMethod("getOsBrand").invoke(buildExClass);
            return "Harmony".equalsIgnoreCase(osBrand.toString());
        } catch (Throwable x) {
            return false;
        }
    }

    /**
     * 获取鸿蒙系统版本号
     *
     * @return 版本号
     */
    public static String getHarmonyVersion() {
        return getProp("hw_sc.build.platform.version", "");
    }

    /**
     * 获取属性
     * @param property
     * @param defaultValue
     * @return
     */
    private static String getProp(String property, String defaultValue) {
        try {
            Class spClz = Class.forName("android.os.SystemProperties");
            Method method = spClz.getDeclaredMethod("get", String.class);
            String value = (String) method.invoke(spClz, property);
            if (TextUtils.isEmpty(value)) {
                return defaultValue;
            }
            return value;
        } catch (Throwable e) {
            e.printStackTrace();
        }
        return defaultValue;
    }

    /**
     * 获得鸿蒙系统版本号(含小版本号,实际上同Android的android.os.Build.DISPLAY)
     * @return 版本号
     */
    public static String getHarmonyDisplayVersion() {
        return android.os.Build.DISPLAY;
    }
}

2.2、HarmonyUtils的调用

当前案例中,在一个activity中实现了对HarmonyUtils工具类的调用。
Activity代码:


import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.widget.TextView;

public class HarmonyActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_harmony);

        TextView tv_is_harmony = findViewById(R.id.tv_is_harmony);
        TextView tv_harmony_version = findViewById(R.id.tv_harmony_version);
        TextView tv_harmony_display_version = findViewById(R.id.tv_harmony_display_version);

        boolean isHarmony = HarmonyUtils.isHarmonyOs();
        tv_is_harmony.setText("is harmony ?  \n  "+ isHarmony);

        String harmonyVersion = HarmonyUtils.getHarmonyVersion();
        tv_harmony_version.setText("harmony version is: \n  "+harmonyVersion);

        String displayVersion = HarmonyUtils.getHarmonyDisplayVersion();
        tv_harmony_display_version.setText("harmony display version is: \n  "+displayVersion);
    }
}
