哪里有抱怨，哪里就有商业机会。
一个人的认知模型决定了他所能看到的事实。
时间就像海绵里的水，挤挤总是有的。再忙，也要抽时间让自己的心灵安静下来，思考自己真正想要的东西。实话讲最近确实很忙，但却忙的充实吧，公司因数字化转型，电商这边忙着分仓的项目，因前期也做了大量的调研，不至于临时抱佛脚而乱忙。最近一段时间大家议论最多的应该蚂蚁金服的事件，抛开其他因素，从国家、社会的大局观角度看（罗老师在脱口秀的经典台词），我觉得马老师做的过分了，借着互联网搞金融，想避开国家的法规。到最后还是被国家约谈，暂缓上市。在中国，A和T目前两家独大，所有人都在围绕他们的平台转，让后起之秀很难生存，可以说是垄断了中国互联网行业。今年的疫情若不是国人手中还有积蓄，国内早发生金融危机，再看看支付宝在地铁里给花呗打的广告，借用情怀来鼓励人们超前消费。万物有道，这是我一直坚信的真理，人一定要学会谦卑，感恩（圣经里也有一句经典：太初有道，神就是道）。周易里面的乾坤二卦就是最好的佐证：
“地势坤，君子以厚德载物。”
君子处事，应像天一样，奋发图强，当你有了成就后需要像大地一样，厚德载物，回馈社会。
回归正题，今天先带大家简单了解下我们java的混淆编译处理，做android开发应该对此非常熟悉，第三方给到的一些sdk都会通过该技术方案来处理源码。
在准备该专题的时候也遇到了好些坑，所以特此记录下，也方便有需要的小伙伴参考。接下来直接上代码：
