This file appears to be in a binary XML format. What is this format and how can it be parsed programmatically (as opposed to using the aapt dump tool in the SDK)?
This binary format is not discussed in the docum开发者_JAVA百科entation here.
Note: I want to access this information from outside the Android environment, preferably from Java.
Use android-apktool
There is an application that reads apk files and decodes XMLs to nearly original form.
Usage:
apktool d Gmail.apk && cat Gmail/AndroidManifest.xml
Check android-apktool for more information
This Java method, that runs on an Android, documents (what I've been able to interpret about) the binary format of the AndroidManifest.xml file in the .apk package. The second code box shows how to call decompressXML and how to load the byte[] from the app package file on the device. (There are fields whose purpose I don't understand, if you know what they mean, tell me, I'll update the info.)

This method reads the AndroidManifest into a byte[] for processing:
public void getIntents(String path) {
try {
JarFile jf = new JarFile(path);
InputStream is = jf.getInputStream(jf.getEntry("AndroidManifest.xml"));
byte[] xml = new byte[is.available()];
int br = is.read(xml);
//Tree tr = TrunkFactory.newTree();
decompressXML(xml);
//prt("XML\n"+tr.list());
} catch (Exception ex) {
console.log("getIntents, ex: "+ex); ex.printStackTrace();
}
} // end of getIntents
Most apps are stored in /system/app which is readable without root my Evo, other apps are in /data/app which I needed root to see. The 'path' argument above would be something like: "/system/app/Weather.apk"
What about using the Android Asset Packaging Tool (aapt), from the Android SDK, into a Python (or whatever) script?
Through the aapt (http://elinux.org/Android_aapt), indeed, you can retrieve information about the .apk package and about its AndroidManifest.xml file. In particular, you can extract the values of individual elements of an .apk package through the 'dump' sub-command. For example, you can extract the user-permissions in the AndroidManifest.xml file inside an .apk package in this way:
$ aapt dump permissions package.apk
Where package.apk is your .apk package.
Moreover, you can use the Unix pipe command to clear the output. For example:
$ aapt dump permissions package.apk | sed 1d | awk '{ print $NF }'
Here a Python script that to that programmatically:
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
In a similar fashion you can extract other information (e.g. package, app name, etc...) of the 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 ""
If instead you want to parse the entire AndroidManifest XML tree, you can do that in a similar way using the xmltree command:
aapt dump xmltree package.apk AndroidManifest.xml
Using Python as before:
#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"))
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]
apkanalyzer
You can use axml2xml.pl tool developed a while ago within android-random project. It will generate the textual manifest file (AndroidManifest.xml) from the binary one.
I'm saying "textual" and not "original" because like many reverse-engineering tools this one isn't perfect and the result will not be complete. I presume either it was never feature complete or simply not forward-compatible (with newer binary encoding scheme). Whatever the reason, axml2xml.pl tool will not be able to extract all the attribute values correctly. Such attributes are minSdkVersion, targetSdkVersion and basically all attributes that are referencing resources (like strings, icons, etc.), i.e. only class names (of activities, services, etc.) are extracted correctly.
However, you can still find these missing information by running aapt tool on the original Android app file (.apk):
aapt l -a <someapp.apk>
apk-parser, https://github.com/caoqianli/apk-parser, a lightweight impl for java, with no dependency for aapt or other binarys, is good for parse binary xml files, and other apk infos.
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();
Check this following WPF Project which decodes the properties correctly.
If your into Python or use Androguard, the Androguard Androaxml feature will do this conversion for you. The feature is detailed in this blog post, with additional documentation here and source here.
Usage:
$ ./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
@Mathieu Kotlin version follows:
fun main(args : Array<String>) {
val fileName = "app.apk"
ZipFile(fileName).use { zip ->
zip.entries().asSequence().forEach { entry ->
if(entry.name == "AndroidManifest.xml") {
zip.getInputStream(entry).use { input ->
val xml = decompressXML(input.readBytes())
//TODO: parse the XML
println(xml)
}

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.
for reference here is my version of Ribo's code. The main difference is that decompressXML() directly returns a String, which for my purposes was a more appropriate usage.
NOTE: my sole purpose in using Ribo's solution was to fetch an .APK file's published version from the Manifest XML file, and I confirm that for this purpose it works beautifully.
EDIT [2013-03-16]: It works beautifully IF the version is set as plain text, but if it's set to refer to a Resource XML, it'll show up as 'Resource 0x1' for example. In this particular case, you'll probably have to couple this solution to another solution that will fetch the proper string resource reference.

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();
}
