Comment analyser le fichier AndroidManifest.xml dans un package .apk
Ce fichier semble être au format XML binaire. Quel est ce format et comment peut-il être analysé par programme (par opposition à l'utilisation de l'outil de vidage aapt dans le SDK)?
Ce format binaire n’est pas abordé dans la documentation ici .
Note: je souhaite accéder à ces informations en dehors de l'environnement Android, de préférence en Java.
Utiliser Android-apktool
Il existe une application qui lit les fichiers apk et décode les XML au format presque original.
Usage:
apktool d Gmail.apk && cat Gmail/AndroidManifest.xml
Vérifiez Android-apktool pour plus d'informations
Cette méthode Java, qui s'exécute sur un Android, documente (ce que j'ai pu interpréter) le format binaire du fichier AndroidManifest.xml dans le package .apk. La deuxième zone de code montre comment appeler decompressXML et comment charger l'octet [] à partir du fichier de package d'application sur le périphérique. (Il y a des champs dont je ne comprends pas le but, si vous savez ce qu'ils veulent dire, dites-moi, je mettrai à jour les informations.)

La plupart des applications sont stockées dans/system/app, qui est lisible sans root my Evo, les autres applications sont dans/data/app, ce dont j'avais besoin comme racine pour pouvoir être visualisé. L'argument 'path' ci-dessus serait quelque chose comme: "/system/app/Weather.apk"
Qu'en est-il de l'utilisation de Android Asset Packaging Tool (aapt), à partir du SDK Android, dans un script Python (ou autre)?
Grâce à aapt ( http://elinux.org/Android_aapt ), vous pouvez en effet récupérer des informations sur le package .apk et sur son fichier AndroidManifest.xml. En particulier, vous pouvez extraire les valeurs d'éléments individuels d'un package .apk à l'aide de la sous-commande 'dump'. Par exemple, vous pouvez extraire le user-permissions dans le fichier AndroidManifest.xml à l'intérieur d'un package .apk de la manière suivante:
$ aapt dump permissions package.apk
Où package.apk est votre package .apk.
De plus, vous pouvez utiliser la commande Unix pipe pour effacer la sortie. Par exemple:
$ aapt dump permissions package.apk | sed 1d | awk '{ print $NF }'
Voici un script Python qui le fait par programme:
import os
import subprocess
#Current directory and file name:
curpath = os.path.dirname( os.path.realpath(__file__) )
filepath = os.path.join(curpath, "package.apk")
#Extract the AndroidManifest.xml permissions:
command = "aapt dump permissions " + filepath + " | sed 1d | awk '{ print $NF }'"
process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=None, Shell=True)
permissions = process.communicate()[0]
print permissions
De la même manière, vous pouvez extraire d'autres informations (par exemple, package, nom de l'application, etc ...) du AndroidManifest.xml:
#Extract the APK package info:
shellcommand = "aapt dump badging " + filepath
process = subprocess.Popen(shellcommand, stdout=subprocess.PIPE, stderr=None, Shell=True)
apkInfo = process.communicate()[0].splitlines()
for info in apkInfo:
#Package info:
if string.find(info, "package:", 0) != -1:
print "App Package: " + findBetween(info, "name='", "'")
print "App Version: " + findBetween(info, "versionName='", "'")
continue
#App name:
if string.find(info, "application:", 0) != -1:
print "App Name: " + findBetween(info, "label='", "'")
continue
def findBetween(s, prefix, suffix):
try:
start = s.index(prefix) + len(prefix)
end = s.index(suffix, start)
return s[start:end]
except ValueError:
return ""
Si, à la place, vous souhaitez analyser l'ensemble de l'arborescence XML d'AndroidManifest, vous pouvez le faire de manière similaire à l'aide de la commande xmltree:
aapt dump xmltree package.apk AndroidManifest.xml
Utiliser Python comme avant:
#Extract the AndroidManifest XML tree:
shellcommand = "aapt dump xmltree " + filepath + " AndroidManifest.xml"
process = subprocess.Popen(shellcommand, stdout=subprocess.PIPE, stderr=None, Shell=True)
xmlTree = process.communicate()[0]
print "Number of Activities: " + str(xmlTree.count("activity"))
print "Number of Services: " + str(xmlTree.count("service"))
print "Number of BroadcastReceivers: " + str(xmlTree.count("receiver"))
Vous pouvez utiliser axml2xml.pl outil développé il y a longtemps dans Android-random projet. Il générera le fichier manifeste textuel (AndroidManifest.xml) à partir du fichier binaire.
Je dis " textuel " et non " original " car, comme de nombreux outils de reverse engineering, celui-ci n'est pas parfait et le résultat ne sera pas complet . Je présume que cela n’a jamais été complet ou simplement pas compatible (avec le nouveau schéma de codage binaire). Quelle que soit la raison, l'outil axml2xml.pl ne pourra pas extraire correctement toutes les valeurs d'attribut. Ces attributs sont minSdkVersion, targetSdkVersion et, fondamentalement, tous les attributs qui font référence à des ressources (telles que des chaînes, des icônes, etc.), c’est-à-dire que seuls les noms de classe (d’activités, de services, etc.) sont extraits correctement.
Cependant, vous pouvez toujours trouver ces informations manquantes en exécutant l'outil aapt sur le fichier d'origine Android app (. apk ):
aapt l -a <someapp.apk>
Cochez cette option WPF Project qui décode les propriétés correctement.
apk-parser, https://github.com/caoqianli/apk-parser , une implémentation légère pour Java, sans dépendance pour aapt ou autres binaires, est bonne pour analyser des fichiers XML binaires et d'autres informations sur les apk.
ApkParser apkParser = new ApkParser(new File(filePath));
// set a locale to translate resource tag into specific strings in language the locale specified, you set locale to Locale.ENGLISH then get apk title 'WeChat' instead of '@string/app_name' for example
apkParser.setPreferredLocale(locale);
String xml = apkParser.getManifestXml();
System.out.println(xml);
String xml2 = apkParser.transBinaryXml(xmlPathInApk);
System.out.println(xml2);
ApkMeta apkMeta = apkParser.getApkMeta();
System.out.println(apkMeta);
Set<Locale> locales = apkParser.getLocales();
for (Locale l : locales) {
System.out.println(l);
}
apkParser.close();
Avec les derniers outils SDK, vous pouvez désormais utiliser un outil appelé apkanalyzer pour imprimer le fichier AndroidManifest.xml d'un fichier APK (ainsi que d'autres éléments, tels que des ressources).

$ ./androaxml.py -i yourfile.apk -o output.xml
$ ./androaxml.py -i AndroidManifest.xml -o output.xml
pour référence, voici ma version du code de Ribo. La principale différence est que decompressXML () renvoie directement une chaîne, qui, pour moi, était une utilisation plus appropriée.
NOTE: Mon seul but en utilisant la solution de Ribo était de récupérer la version publiée d'un fichier .APK à partir du fichier XML Manifest, et je confirme que, dans ce but, cela fonctionne à merveille.
EDIT [2013-03-16]: Cela fonctionne à merveilleSIla version est définie en texte brut, mais si elle est définie pour faire référence à un XML de ressource, elle apparaîtra sous la forme "Ressource 0x1", par exemple. . Dans ce cas particulier, vous devrez probablement associer cette solution à une autre solution permettant d'extraire la référence de ressource chaîne appropriée.

Dans Android studio 2.2, vous pouvez directement analyser l'apk. Goto build-analyse apk. Sélectionnez l'apk, accédez à androidmanifest.xml. Vous pouvez voir les détails de androidmanifest.
Je cours avec le code Ribo affiché ci-dessus depuis plus d'un an et il nous a bien servi. Cependant, avec les mises à jour récentes (Gradle 3.x), je ne pouvais plus analyser le fichier AndroidManifest.xml, je obtenais des erreurs d'index en dehors des limites et, en général, le fichier n'était plus analysé.
Mise à jour: Je crois maintenant que nos problèmes étaient liés à la mise à niveau vers Gradle 3.x. Cet article explique comment AirWatch a eu des problèmes et peut être résolu en utilisant un paramètre Gradle pour utiliser aapt au lieu de aapt2 AirWatch semble être incompatible avec Android Plugin for Gradle 3.0.0-beta1
En cherchant autour de moi, je suis tombé sur ce projet open source, qui a été mis à jour et qui m'a permis de bien comprendre les anciens fichiers APK que je pouvais auparavant analyser et les nouveaux fichiers APK que la logique de Ribo a projetés d'exceptions
https://github.com/xgouchet/AXML
De son exemple c'est ce que je fais
zf = new ZipFile(apkFile);
//Getting the manifest
ZipEntry entry = zf.getEntry("AndroidManifest.xml");
InputStream is = zf.getInputStream(entry);
// Read our manifest Document
Document manifestDoc = new CompressedXmlParser().parseDOM(is);
// Make sure we got a doc, and that it has children
if (null != manifestDoc && manifestDoc.getChildNodes().getLength() > 0) {
//
Node firstNode = manifestDoc.getFirstChild();
// Now get the attributes out of the node
NamedNodeMap nodeMap = firstNode.getAttributes();
// Finally to a point where we can read out our values
versionName = nodeMap.getNamedItem("Android:versionName").getNodeValue();
versionCode = nodeMap.getNamedItem("Android:versionCode").getNodeValue();
}
J'ai trouvé AXMLPrinter2, une application Java du projet Android4Me qui fonctionnait parfaitement avec le fichier AndroidManifest.xml que j'avais (et affiche le code XML de manière bien formatée) . http://code.google. com/p/Android4me/téléchargements/detail? name = AXMLPrinter2.jar
Une note .. il (et le code sur cette réponse de Ribo) ne semble pas gérer tous les fichiers XML compilés que j'ai rencontrés. J'ai trouvé un où les chaînes ont été stockées avec un octet par caractère, plutôt que le format à double octet qu'il suppose.
