react - Cómo analizar el archivo AndroidManifest.xml dentro de un paquete.apk
intent android (14)
Este archivo parece estar en formato XML binario. ¿Qué es este formato y cómo se puede analizar mediante programación (en lugar de usar la herramienta de volcado aapt en el SDK)?
Este formato binario no se trata en la documentación here .
Nota : Deseo acceder a esta información desde fuera del entorno de Android, preferiblemente desde Java.
Utilice android-apktool
Hay una aplicación que lee archivos apk y decodifica XML en forma casi original.
Uso:
apktool d Gmail.apk && cat Gmail/AndroidManifest.xml
Ver android-apktool para más información
¿Qué hay de usar la herramienta de empaquetado de activos de Android (aapt), del SDK de Android, en un script de Python (o lo que sea)?
A través de aapt ( http://elinux.org/Android_aapt ), de hecho, puede recuperar información sobre el paquete .apk y sobre su archivo AndroidManifest.xml . En particular, puede extraer los valores de los elementos individuales de un paquete .apk a través del comando secundario ''volcar'' . Por ejemplo, puede extraer los permisos de usuario en el archivo AndroidManifest.xml dentro de un paquete .apk de esta manera:
$ aapt dump permissions package.apk
Donde package.apk es tu paquete .apk .
Además, puede usar el comando de tubería Unix para borrar la salida. Por ejemplo:
$ aapt dump permissions package.apk | sed 1d | awk ''{ print $NF }''
Aquí una secuencia de comandos de Python que programáticamente:
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 manera similar, puede extraer otra información (por ejemplo, paquete , nombre de la aplicación , etc.) de 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, en cambio, desea analizar todo el árbol XML de AndroidManifest, puede hacerlo de forma similar con el comando xmltree :
aapt dump xmltree package.apk AndroidManifest.xml
Usando Python como antes:
#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"))

Puede usar la herramienta axml2xml.pl desarrollada hace un tiempo dentro del proyecto android-random . Generará el archivo de manifiesto textual (AndroidManifest.xml) del archivo binario.
Estoy diciendo " textual " y no " original " porque, como muchas herramientas de ingeniería inversa, esta no es perfecta y el resultado no será completo . Supongo que nunca fue característica completa o simplemente no compatible con versiones anteriores (con un esquema de codificación binario más nuevo). Cualquiera que sea el motivo, la herramienta axml2xml.pl no podrá extraer todos los valores de los atributos correctamente. Dichos atributos son minSdkVersion, targetSdkVersion y básicamente todos los atributos que hacen referencia a recursos (como cadenas, iconos, etc.), es decir, solo los nombres de clase (de actividades, servicios, etc.) se extraen correctamente.
Sin embargo, aún puede encontrar la información que falta ejecutando la herramienta aapt en el archivo de la aplicación original de Android ( .apk ):
aapt l -a <someapp.apk>
Si estás en Python o usas Androguard , la función Androguard Androaxml hará esta conversión por ti. La función se detalla en esta publicación de blog , con documentación adicional aquí y fuente aquí .
Uso:
$ ./androaxml.py -h
Usage: androaxml.py [options]
Options:
-h, --help show this help message and exit
-i INPUT, --input=INPUT
filename input (APK or android''s binary xml)
-o OUTPUT, --output=OUTPUT
filename output of the xml
-v, --version version of the API
$ ./androaxml.py -i yourfile.apk -o output.xml
$ ./androaxml.py -i AndroidManifest.xml -o output.xml
apk-parser, https://github.com/caoqianli/apk-parser , un ligero impl para java, sin dependencia para aapt u otros binarys, es bueno para analizar archivos binarios xml y otras informaciones de 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();
para referencia aquí está mi versión del código de Ribo. La principal diferencia es que descompressXML () devuelve directamente una Cadena, que para mi propósito era un uso más apropiado.
NOTA: mi único propósito en el uso de la solución de Ribo fue obtener una versión publicada del archivo .APK del archivo Manifiesto XML, y confirmo que para este fin funciona muy bien.
EDITAR [2013-03-16]: Funciona muy bien SI la versión está configurada como texto sin formato, pero si está configurada para referirse a un XML de recursos, aparecerá como ''Recurso 0x1'', por ejemplo. En este caso particular, probablemente tenga que acoplar esta solución a otra solución que busque la referencia de recursos de cadena adecuada.

Hope it can help other people too.
I found the AXMLPrinter2, a Java app over at the Android4Me project to work fine on the AndroidManifest.xml that I had (and prints the XML out in a nicely formatted way). http://code.google.com/p/android4me/downloads/detail?name=AXMLPrinter2.jar
One note.. it (and the code on this answer from Ribo) doesn''t appear to handle every compiled XML file that I''ve come across. I found one where the strings were stored with one byte per character, rather than the double byte format that it assumes.
I have been running with the Ribo code posted above for over a year, and it has served us well. With recent updates (Gradle 3.x) though, I was no longer able to parse the AndroidManifest.xml, I was getting index out of bounds errors, and in general it was no longer able to parse the file.
Update: I now believe that our issues was with upgrading to Gradle 3.x. This article describes how AirWatch had issues and can be fixed by using a Gradle setting to use aapt instead of aapt2 AirWatch seems to be incompatible with Android Plugin for Gradle 3.0.0-beta1
In searching around I came across this open source project, and it''s being maintained and I was able to get to the point and read both my old APKs that I could previously parse, and the new APKs that the logic from Ribo threw exceptions
https://github.com/xgouchet/AXML
From his example this is what I''m doing
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();
}
In Android studio 2.2 you can directly analyze the apk. Goto build- analyze apk. Select the apk, navigate to androidmanifest.xml. You can see the details of androidmanifest.
With the latest SDK-Tools, you can now use a tool called the apkanalyzer to print out the AndroidManifest.xml of an APK (as well as other parts, such as resources).
[android sdk]/tools/bin/apkanalyzer manifest print [app.apk]
it can be helpful
