Android安装包APK文件中的AndroidManifest.xml记录了应用的详细信息，发布时该文件已被编译成二进制码，所以无法正常查看其内容。比如我想查看这个包的Package和Version信息(这指的是在服务端)。
AXMLPrinter2.jar可以很好的帮我做到这点，如果你有Java环境，可以通过以下命令行解码xml中的内容
java -jar AXMLPrinter2.jar AndroidManifest.xml > AndroidManifest.txt
|
当然你可以在dotnet程序里通过调用外部进程来运行此
ProcessStartInfo ph =
new
ProcessStartInfo(
"AXMLPrinter2.jar"
,
"AndroidManifest.xml > AndroidManifest.txt"
);
Process.Start(ph);
|
不过这在asp.net的web程序因权限问题会有诸多不便，因我的生产环境没有Java，所以想在C#下实现这个功能。AXMLPrinter2.jar是有源代码的(Eclipse project)，你完全可以用C#重写一遍 :)
借助伟大的IKVM.NET (dotnet上java的实现)，我可以把AXMLPrinter2.jar转换成一个dotnet的Assembly
ikvmc -
out
:AXMLPrinter2.dll AXMLPrinter2.jar
|
引用转换后的dll和IKVM的lib(IKVM.Runtime.dll,IKVM.OpenJDK.Core.dll)，这样就可以很方便的在C#中调用AXMLPrinter2.jar里的方法了，下面是C#中的一段调用
