针对Titanium中需要特定的功能可能需要开发者定制，如二维码等。所以需要自己开发相关的module在项目中使用。

开发环境准备

  下载titanium studio

  下载eclipse + ant

  下载android sdk

  下载android ndk

官方推荐：

注意：必须参考下面的官方网址,   python在windows环境下不用安装，本身titanium studio已经装了

https://wiki.appcelerator.org/display/guides/Android+Module+Development+Guide

关于titanium自动生成module的模板在：

${Titanium SDK}\mobilesdk\win32\1.8.2\module\android\templates\src\___MODULE_ID_AS_FOLDER___

本文将简单一下关于titanium module的描述。

ant编译module工程

1）将此工程放到eclipse下（带有ant环境），编辑builder.properties文件，加上android ndk路径。如下：

android.ndk=C:\android-ndk\android-ndk-r8

针对android的NDK如果在环境变量中设置，那么就可以不再builder.properties文件中设置，否则必须设置。

编译成功后会在dist目录下生成相应的zip包。

如何调用的module

1.配置tiapp.xml文件中模块

<modules>
      <module version="1.1">com.easyway</module>
    </modules>

 2.将zip解压之后的modules拷贝到对应的titanium module应用的根目录中。

如下：

3.调用：

// This is a test harness for your module
// You should do something interesting in this harness 
// to test out the module and to provide instructions 
// to users on how to use it by example.


// open a single window
var win = Ti.UI.createWindow({
	backgroundColor:'white'
});
var label = Ti.UI.createLabel();
win.add(label);
win.open();

// TODO: write your module tests here
var hellomodule = require('com.easyway');
Ti.API.info("module is => " + hellomodule);

label.text = hellomodule.example();

Ti.API.info("module exampleProp is => " + hellomodule.exampleProp);
hellomodule.exampleProp = "This is a test value";

if (Ti.Platform.name == "android") {
	var proxy = hellomodule.createExample({
		message: "Creating an example Proxy",
		backgroundColor: "red",
		width: 100,
		height: 100,
		top: 100,
		left: 150
	});

	proxy.printMessage("Hello world!");
	proxy.message = "Hi world!.  It's me again.";
	proxy.printMessage("Hello world!");
	win.add(proxy);
}
