连接手机，adb shell 进入 Android Shell 模式，输入 getprop 获取系统属性值

通过上面方法拿到属性名，然后通过下面方法获取到系统的属性值

/**  * 获取build.prop文件中的某个属性  *  * @param propName 属性名称  * @return 属性值  */ public static String getSystemProperty(String propName) {
      Log.i(LOG_TAG, "getSystemProperty in time: " + System.currentTimeMillis());     String line;     BufferedReader input = null;     try {
          Process p = Runtime.getRuntime().exec("getprop " + propName);         input = new BufferedReader(                 new InputStreamReader(p.getInputStream()), 1024);         line = input.readLine();         input.close();     } catch (Exception ex) {
          Log.e(LOG_TAG, "Unable to read sysprop " + propName, ex);         return null;     } finally {
          if (input != null) {
              try {
                  input.close();             } catch (Exception e) {
                  Log.e(LOG_TAG, "Exception while closing InputStream", e);             }         }     }     Log.i(LOG_TAG, "getSystemProperty out time: " + System.currentTimeMillis());     return line; }
