Android 让你一分钟打一千个渠道包，丢掉该死的打包工具！

转自：http://blog.csdn.net/lanfei1027/article/details/50255355

如题所示，相信很多程序员开发完App之后，然后就是上线到各大应用市场，但是国内这么多应用市场，每个市场的渠道都必须要不一样，才能达到数据分析的结果，往往这个时候，就需要我们去打各种渠道包了，每次把渠道号换一下，就进行一次打包流程，速度实在是慢死人，当然现在也有一些自动化打包工具，进行脚本打包，不过这个也要花很长时间，几十个渠道包，需要打上半小时甚至是一个小时。

没错，今天就说一下如何一分钟就可以打出来一千渠道包，其实，为什么我们每次打渠道包，所属要时间都是很长，因为我们每次都是重新打包，没错…就是重新打包，只是把渠道号换了一下，然后需要重新打包一次。今天我要说这个，不需要你重新打包，只需要你把APK里面某个文件名称改掉，然后就实现修改渠道号的功能…..

第一步

首先我们在apk某个目录下面新建一个文件，文件名称就是我们的渠道号：

如图



在APK解压之后的META-INF目录下面新建一个叫：channel~test的文件，其中test就是我们的渠道号。

第二步

然后我们在apk里面读取这个文件名称，代码如下：

<code class="hljs java has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-javadoc" style="color: rgb(136, 0, 0); box-sizing: border-box;">/**

第三步

其实上面就已经基本实现快速打包了，那么为什么还有第三步呢？因为上面的过程需要你手动进行，那么我们可以写个小程序让他自己进行，这里我就不贴代码了。感兴趣的同学可以自己去写一下，就是把APK压缩成ZIP，然后在里面新建一个文件，名称弄成对应的名称，就完事了。怎么打很多个呢？写个循环就可以啦……..

这样就实现了快速的打很多渠道包的需求了，而且也不需要重新签名。非常的快捷、方便。唯一的缺点就是没有进行跟换签名的，如果有需求是要换签名的，这种方式可能就不能实现了。

看到这里是不是觉得非常简单呢？没错….就是非常简单，看了完这篇blog之后，你就可以丢掉该死的脚本打包工具了，慢不说，还占用电脑，说不准还会出现打包出错的情况。用这种方式即快速又不会出错还不会影响你正常使用电脑。

如果还有其他实现方式的，欢迎大神下边留言交流哈………..
