android 多渠道打包工具 可打包libs和.so文件

android應用上傳時，需要區分開每個渠道。一般都會在配置文件中更改一個渠道id,如果有多個渠道，手動修改並生成apk的話會非常麻煩，而且增大出錯概率。

在這分享一個打包工具類。網上也有類似的，我是在它的基礎上做的優化，特別是打包so文件，一句小小的命令廢了好大勁。

我們項目中使用的umeng做統計分析工具， umeng在分渠道打包的時候需要修改manifest.xml中的

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

該值放到了strings.xml中<string name="channel_name">app_channel</string>,所以在編譯的時候只需修改app_channel。

下面是工具類，直接運行即可.
