Apk reader

Auto build Nuget

Android package file reader assembly. Can read apk files, android xml files (AndroidManifes.xml, *.xml), Dalvik executable format (dex), android resource files (arsc).

Usage:

using(ApkFile apk = new ApkFile(apkFilePath))
{
    if(apk.IsValid)
    {
        If(apk.AndroidManifest!=null)
        {//AndroidManifest.xml
            Console.WriteLine("Package: {0}", apk.AndroidManifest.Package);
            Console.WriteLine("Application name: {0} ({1})", apk.AndroidManifest.Application.Label, apk.AndroidManifest.VersionName);
            //...
        }

        if(apk.Resources!=null)
        {//resources.arsc
            //...
        }

        foreach(String filePathInApk in apk.GetFiles())
            switch(Path.GetExtension(filePathInApk).ToLowerInvariant()){
            case ".dex":
                using(Stream stream=apk.GetFileStream(filePathInApk, true)){
                    if(stream!=null)
                        using(DexFile dex=new DexFile(new StreamLoader(stream)))
                        {//Davlik executables
                            //...
                        }
                }
            break;
            }
    }
}
