运行android教程源码时遇到的问题
由于android版本众多，加上有些教程的源码年代较久，因而会有版本问题的冲突。
解决：
- 将default.properties文件里的target=android-5(举例而已，不一定是5）换成所需要的版本，比如2.2是android-8（之前说是要自个导入jar包，但是将此处改了之后，jar包就自动加入了。）
- 在AndroidManifest.xml文件中加入" <uses-sdk android:minSdkVersion="8" />"
The Zen of Python, by Tim Peters
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!

所谓技术宅拯救世界。
又所谓一屋不扫，何以扫天下。
所以，先收拾屋子吧！
