通过反射判断当前设备是Android还是Harmony

private static final String HARMONY_OS = “harmony”;
/**

• check the system is harmony os
• @return true if it is harmony os
  */
  public static boolean isHarmonyOS() {
  try {
  Class clz = Class.forName(“com.huawei.system.BuildEx”);
  Method method = clz.getMethod(“getOsBrand”);
  return HARMONY_OS.equals(method.invoke(clz));
  } catch (ClassNotFoundException e) {
  Log.e(TAG, “occured ClassNotFoundException”);
  } catch (NoSuchMethodException e) {
  Log.e(TAG, “occured NoSuchMethodException”);
  } catch (Exception e) {
  Log.e(TAG, “occur other problem”);
  }
  return false;
  }
