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;
/**
* 齐行超
* 2020-02-16
*/
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);
}
}
