生成唯一id

1.API >=9:通过“Build.SERIAL”这个属性来保证ID的独一无二。

  String m_szDevIDShort = "35" + 
        Build.BOARD.length()%10+ Build.BRAND.length()%10 + 

        Build.CPU_ABI.length()%10 + Build.DEVICE.length()%10 + 

        Build.DISPLAY.length()%10 + Build.HOST.length()%10 + 

        Build.ID.length()%10 + Build.MANUFACTURER.length()%10 + 

        Build.MODEL.length()%10 + Build.PRODUCT.length()%10 + 

        Build.TAGS.length()%10 + Build.TYPE.length()%10 + 

        Build.USER.length()%10 ; //13 位

try {
    serial = android.os.Build.class.getField("SERIAL").get(null).toString();
   //API>=9 使用serial号
    return new UUID(m_szDevIDShort.hashCode(), serial.hashCode()).toString();
} catch (Exception exception) {
    //serial需要一个初始化
    serial = "serial"; // 随便一个初始化
}
//使用硬件信息拼凑出来的15位号码
return new UUID(m_szDevIDShort.hashCode(), serial.hashCode()).toString();

api<9

public static String getDeviceSerial() {
  String serial = "unknown";
  try {
   Class clazz = Class.forName("android.os.Build");
   Class paraTypes = Class.forName("java.lang.String");
   Method method = clazz.getDeclaredMethod("getString", paraTypes);
   if (!method.isAccessible()) {
    method.setAccessible(true);
   }
   serial = (String)method.invoke(new Build(), "ro.serialno");
  } catch (ClassNotFoundException e) {
   e.printStackTrace();
  } catch (NoSuchMethodException e) {
   e.printStackTrace();
  } catch (InvocationTargetException e) {
   e.printStackTrace();
  } catch (IllegalAccessException e) {
   e.printStackTrace();
  }
  return serial;
