android uuid

UUID+设备号序列号 唯一识别码（不可变）

private String getMyUUID(){
  final TelephonyManager tm = (TelephonyManager) getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);    
  final String tmDevice, tmSerial, tmPhone, androidId;    
  tmDevice = "" + tm.getDeviceId();   
  tmSerial = "" + tm.getSimSerialNumber();    
  androidId = "" + android.provider.Settings.Secure.getString(getContentResolver(),android.provider.Settings.Secure.ANDROID_ID);    
  UUID deviceUuid = new UUID(androidId.hashCode(), ((long)tmDevice.hashCode() << 32) | tmSerial.hashCode());    
  String uniqueId = deviceUuid.toString();
  Log.d("debug","uuid="+uniqueId);
  return uniqueId;
 }

 

java 获取可变UUID

 private String getMyUUID(){
  UUID uuid = UUID.randomUUID();
     String uniqueId = uuid.toString();
   Log.d("debug","----->UUID"+uuid);
    return uniqueId;
   }

 

获得的格式：如下样子
