[Tools-004] How to extract androidmanifest.xml from APK and extract the appropriate information

As with the previous article, we also need to verify some of the apk , such as Umengkey,adkey,talkingdata , then we also need to unzip the apk file, and then extract One of the androidmanifest.xml. Then parse the XML to analyze and contrast the content.

1. Unzip the APK file

if (Path.getextension (FilePath).   Equals (". apk")) {//Get the app name String appName = path.getfilenamewithoutextension (FilePath);   Export directory String Outpath = "tempandroid\\" + appName;   Create an extract stream zipinputstream s = new Zipinputstream (File.openread (FilePath));   String androidmanifestname = "Androidmanifest.xml";   ZipEntry Theentry;   BOOL found = false;      while ((Theentry = S.getnextentry ()) = null) {Console.WriteLine (theentry.name);      Gets the extracted filename string filename = Path.getfilename (theentry.name);         　　Traverse Lookup configuration file if (Androidmanifestname! = null) {if (Filename.equals (Androidmanifestname)) {            Found = true;            if (Outpath.length > 0) {directory.createdirectory (Outpath);            　　} using (FileStream StreamWriter = file.create (outpath + "\ \" + androidmanifestname)) {                int size = 2048;                byte[] data = new byte[2048]; while (true) {               　  Size = s.read (data, 0, data.                    Length);                    if (Size > 0) {streamwriter.write (data, 0, size);                    } else {break;                 }} streamwriter.flush ();                 StreamWriter.Close (); The decryption operation is performed because the signed XML must be decrypted, otherwise the binary file String execstring = "Java-jar" + Decodexmljar + "" + Outpath + "\ \" + A                 Ndroidmanifestname + ">" + Outpath + "\\AndroidManifest2.xml";                 RunCommand (execstring);                 Perform a file replacement operation Thread.Sleep (3000);                 File.delete (Outpath + "\" + androidmanifestname);            File.move (Outpath + "\\AndroidManifest2.xml", Outpath + "\ \" + androidmanifestname);         } break;  }}} s.close ();　　 if (found = = False) {Logappend (appName + "-------Invalid", false, false); LogaPpend (Environment.NewLine, False, false); }}

2. The extracted XML file is a binary file that must be decrypted, using the Axmlprinter2.jar, as follows

private string Decodexmljar = "Axmlprinter2.jar";//Perform decryption operation String execstring = "Java-jar" + Decodexmljar + "" + Outpath + "\ \" + Androidmanifestname + ">" + Outpath + "\\AndroidManifest2.xml"; RunCommand (execstring);//Perform file substitution operation Thread.slee P (3000); File.delete (Outpath + "\" + androidmanifestname); File.move (Outpath + "\\AndroidManifest2.xml", Outpath + "\ \" + androidmanifestname);/** * Run command * */private void RunCommand (String command)　　{Process p = new process ();　　p.StartInfo.FileName = "cmd.exe";　　P.startinfo.useshellexecute = false;　　P.startinfo.redirectstandardinput = true;　　P.startinfo.redirectstandardoutput = true;　　P.startinfo.redirectstandarderror = true;　　P.startinfo.createnowindow = true;　　　　P.startinfo.workingdirectory = Application.startuppath;　　　　try {p.start ();　　　　Console.WriteLine ("Command:" + COMMAND + "&exit");　　　　P.standardinput.writeline (command);　　　　P.standardoutput.close ();　　P.close (); } catch (Exception E1) {Console.WriteLine ("Error" + E1. Message); }}

3. After decrypting the file, we can use the XML read to process, here we refer to the package is system.xml,c# own

XmlDocument doc = new XmlDocument ();//load XML file Doc. Load (pathInfo);//Get root node XmlElement Rootelem = Doc. documentelement;//Gets the person child node collection  xmlnodelist metadatanodes = Rootelem.getelementsbytagname ("Meta-data"); String AppKey = Rootelem.getattribute ("package"); String Mangguokey = ""; String talkingData = ""; String Umengkey = ""; String Qihukey = ""; foreach (XmlNode metadatanode in metadatanodes) {if (Metadatanode.　　　　NodeType = = xmlnodetype.element) {XmlElement nodeelement = (XmlElement) Metadatanode; String name = Nodeelement.　　　　GetAttribute ("Android:name"); if ("Umeng_appkey"). Equals (name)) {Umengkey = nodeelement.　　　　GetAttribute ("Android:value"); } else if ("td_app_id". Equals (name)) {TalkingData = nodeelement.　　　　GetAttribute ("Android:value"); } else if ("mango_id". Equals (name)) {Mangguokey = nodeelement.　　　　GetAttribute ("Android:value"); } else if ("qh_360_id". Equals (name)) {Qihukey = nodeelement.　　　　GetAttribute ("Android:value");　}　}} 

Combining the above three steps, we can easily extract the information from the XML to do the comparison.

Conclusion
