android 多渠道打包

android应用上传时，需要区分开每个渠道。一般都会在配置文件中更改一个渠道id,如果有多个渠道，手动修改并生成apk的话会非常麻烦，而且增大出错概率。

在这分享一个打包工具类.

我们项目中使用的umeng做统计分析工具， umeng在分渠道打包的时候需要修改manifest.xml中的

<meta-data  android:name="UMENG_CHANNEL" android:value="@string/channel_name" />  value值。

该值放到了strings.xml中<string name="channel_name">app_channel</string>,所以在编译的时候只需修改app_channel。

下面是工具类，直接运行即可.

注意事项:

1. 正确设置各个path路径.

2. channelFlag的值要与 strings.xml 中channel_name的value一致.

3. 运行java文件是先运行一下android工程,确保bin目录下有最新的apk.

4. 运行过程中不要手动停止,如手动停止,再次运行时请检查strings.xml中channel_name的value值,如不为app_channel,请修改

5. 如有error: Error parsing XML: not well-formed (invalid token)类似错误，注意设置字符编码
