利用机智云APP学习JAVA安卓

学习android

昨天遇到了一个很好的视频教程，今天果断把电脑拿回来，在宿舍开始我的android学习之路，学东西不系统，坚持不了只能一点一点摸索，今天进展非常顺利，爽的很，今天成功按照教程将机智云官方SDk添加到androidstudio中。
一、成功完成了SDK的初始化
二、完成了启动图的添加
三、完成了bug的修复，一步一步心惊肉跳，紧张无比。。。
四、完成了android 6.0以后的权限动态验证。
教程链接–发烧友学院–哎呀，太好了这个网站，很丰富的教程。

今天学的很舒服，很开心。喜欢这种流畅的感觉，最讨厌编程的时候发生各种问题了，但是有问题能完美解决，是最舒服的。
