尝试Android Scripting Environment之二
作者：宋立新
Email：zjujoe@yahoo.com
前言
前文<<尝试ASE>>中我们写了一个脚本，可以通过ADB在PC端控制ASE Python脚本的执行。这里，我们就通过该脚本，研究一下ASE自带的例子，从而知道ASE的能力，为我们或许编写自己的测试脚本做准备。
简介
ASE通过Android Façade封装了很多方法，这些方法调用了Android的API来实现功能。我们正是通过这些方法来实现我们的功能。
从：http://code.google.com/p/android-scripting/wiki/AndroidFacadeAPI
可知，这些方法都有相同的返回值：
All ASE API calls return an object with three fields:
- id: a strictly increasing, numeric id associated with the API call.
- result: the return value of the API call, or null if there is no return value.
- error: a description of any error that occurred or null if no error occurred.
从：http://code.google.com/p/android-scripting/wiki/ApiReference
可以查到所有的API
当然，具体看示例代码时会发现，除了Android FacadeAPI对应的android package外，还用到很多其他package,由于本人对python不熟（语法还是大体知道的，但是那么多package就基本不懂了），所以研究的过程中需要不时Google一下那些包的使用，一并记录在此。
Python的参考可以用：http://docs.python.org/release/2.5/lib/lib.html
当然，ASE带的python似乎还添加了一些非标准包，比如Google doc service.
hello_world.py
1 import android
这里导入android包
2 droid = android.Android()
获得android对象
3 droid.makeToast('Hello, Android!')
调用android方法：makeToast
对Android API熟悉的话应该知道Toast就是一个提示对话框。
test.py各种测试
比较直白的部分我们就不分析了。。。
import部分
1 import sys
2 import types

4 # Test imports.
5 import android
6 import BeautifulSoup
From:http://hi.baidu.com/javalang/blog/item/84bac4bf731fb80f18d81fe1.html
Beautiful Soup是用Python写的一个HTML/XML的解析器，它可以很好的处理不规范标记并生成剖析树(parse tree)。它提供简单又常用的导航（navigating），搜索以及修改剖析树的操作。它可以大大节省你的编程时间。对于Ruby，使用Rubyful Soup。
7 import gdata.docs.service
From:http://code.google.com/p/gdata-python-client/
The Google Data APIs (Google Data) provide a simple protocol for reading and writing data on the web. Though it is possible to use these services with a simple HTTP client, this library provides helpful tools to streamline your code and keep up with server-side changes.
8 import sqlite3
From:http://docs.python.org/release/2.5/lib/module-sqlite3.html
SQLite is a C library that provides a lightweight disk-based database that doesn't require a separate server process and allows accessing the database using a nonstandard variant of the SQL query language. Some applications can use SQLite for internal data storage. It's also possible to prototype an application using SQLite and then port the code to a larger database such as PostgreSQL or Oracle.
9 import termios
From:http://docs.python.org/release/2.5/lib/module-termios.html
This module provides an interface to the POSIX calls for tty I/O control. For a complete description of these calls, see the POSIX or Unix manual pages. It is only available for those Unix versions that support POSIX termios style tty I/O control (and then only if configured at installation time).
10 import time
From:http://docs.python.org/release/2.5/lib/module-time.html
This module provides various time-related functions. It is always available, but not all functions are available on all platforms. Most of the functions defined in this module call platform C library functions with the same name. It may sometimes be helpful to consult the platform documentation, because the semantics of these functions varies among platforms.
11 import xmpp
From:http://xmpppy.sourceforge.net/
xmpppy is a Python library that is targeted to provide easy scripting with Jabber. Similar projects are Twisted Wordsand jabber.py.
