很久没有写博客了，也算应胡哥的要求，更多的是对最这段时间自己的学习和生活的一个回顾和总结吧，无关技术。
想想自己这段时间，特别是最近这几天，确实是有点过于放松了。感觉总是不在状态，好像慢慢地没有了刚来公司时那种冲劲，那么的毅然决然。胡哥的这次博客要求，也算给自己提了个醒吧。不管怎么样，坚持下去，才有机会，不能刚刚有点起步，就开始松懈，我确实该要醒悟。就像乌拉多恩的歌曲《鸟人》里写的那样，要么飞，要么坠落，这是生命的规则！
虽然无关技术，既然说到了Android，也就说说这段时间Android的学习吧。
一开始开始接触Android，是因为赵欢老师的《ARM体系结构与编程》的课程设计，要求我们做个开发项目。在这之前，我想我连菜鸟都算不上，简直是一穷二白，什么都不会。只剩下2个星期的时候，我们（我和另一个同学组成一个项目小组）决定做个基于Android平台的关于GPS的百度地图小项目。做之前，我们连Android工程都还不会建。花了一个星期，各种百度，各种看视频、查资料，总算是把开发环境搭建好，学会了第一个Android工程：《Hello World！》，大概了解到了，一个Android工程，到底包括那些工程文件，哪些文件有什么作用，勉强算是入了门。然后又花了一个星期，我的同学负责界面以及功能的设计，我负责敲代码实现，每天从上午10点开始，到晚上9点，除了吃饭时间，基本就是坐在电脑前，各种百度，要实现一个什么样的功能，不会？百度！运行程序出问题了？百度！总之就是不断的尝试以及各种百度中，慢慢的拼凑成了一个“项目”！
不管它的功能多么的不完善，不管它多么的不像是个真正的项目，但是，两个星期，从不会到有所了解，从无到有，它真的就诞生在了我们的手上！我的同学给它起了个名字：无花果！象征着我们整个项目开发的过程：没有开花就结果！
现在回想起那几天，不管我们是多么的菜，多么的不懂技术，但是有了一个明确的目标，有了来自课程的压力，那种一往无前的冲劲，不管是多么的横冲直撞，我们总算是做了出来，不管结果是多么的不专业，不管结果是多么的不堪入目，起码，这是一个从无到有的开始，这是一颗无花果！
今天算是给自己提个醒吧。加油，我能做到！
（代码和文档就当是留念了）
