ApkNet 1.0.0

apk-net

.NET library written in C# for reading/parsing APK manifest (AndroidManifest.xml) and resource data (Resources.arsc).

Project Info

This project originaly forked from hylander0/Iteedee.ApkReader.

All namespaces are changed and started to maintain actively.

Using the ApkReader Library

The library handles everything after you have uncompressed/unzipped the APK using your choice tool or library. I have used the [ICSharpCode.SharpZipLib][5] library to uncompressed the APK in my example.

Below I am uncompromising the AndroidManifest.xml and Resources.arsc files and passing the byte array data to the ApkReader library:

byte[] manifestData = null;
byte[] resourcesData = null;
using (ICSharpCode.SharpZipLib.Zip.ZipInputStream zip = new ICSharpCode.SharpZipLib.Zip.ZipInputStream(File.OpenRead(path)))
{
    using (var filestream = new FileStream(path, FileMode.Open, FileAccess.Read))
    {
        ICSharpCode.SharpZipLib.Zip.ZipFile zipfile = new ICSharpCode.SharpZipLib.Zip.ZipFile(filestream);
        ICSharpCode.SharpZipLib.Zip.ZipEntry item;
        while ((item = zip.GetNextEntry()) != null)
        {
            if (item.Name.ToLower() == "androidmanifest.xml")
            {
                manifestData = new byte[50 * 1024];
                using (Stream strm = zipfile.GetInputStream(item))
                {
                    strm.Read(manifestData, 0, manifestData.Length);
                }

            }
            if (item.Name.ToLower() == "resources.arsc")
            {
                using (Stream strm = zipfile.GetInputStream(item))
                {
                    using (BinaryReader s = new BinaryReader(strm))
                    {
                        resourcesData = s.ReadBytes((int)item.Size);

                    }
                }
            }
        }
    }
}

After you have uncompressed and extracted the necessary data, simply pass in the data objects and it returns an APKInfo object.

ApkReader apkReader = new ApkReader();
ApkInfo info = apkReader.extractInfo(manifestData, resourcesData);

APKInfo object contains all of the meta-data for that APK.

Console.WriteLine(string.Format("Package Name: {0}", info.packageName));
Console.WriteLine(string.Format("Version Name: {0}", info.versionName));
Console.WriteLine(string.Format("Version Code: {0}", info.versionCode));

Console.WriteLine(string.Format("App Has Icon: {0}", info.hasIcon));
if(info.iconFileName.Count > 0)
    Console.WriteLine(string.Format("App Icon: {0}", info.iconFileName[0]));
Console.WriteLine(string.Format("Min SDK Version: {0}", info.minSdkVersion));
Console.WriteLine(string.Format("Target SDK Version: {0}", info.targetSdkVersion));

if (info.Permissions != null && info.Permissions.Count > 0)
{
    Console.WriteLine("Permissions:");
    info.Permissions.ForEach(f =>
    {
        Console.WriteLine(string.Format("   {0}", f));
    });
}
else
    Console.WriteLine("No Permissions Found");

Console.WriteLine(string.Format("Supports Any Density: {0}", info.supportAnyDensity));
Console.WriteLine(string.Format("Supports Large Screens: {0}", info.supportLargeScreens));
Console.WriteLine(string.Format("Supports Normal Screens: {0}", info.supportNormalScreens));
Console.WriteLine(string.Format("Supports Small Screens: {0}", info.supportSmallScreens));
