Introduction

An APK is just a ZIP archive, but the AndroidManifest.xml inside it is usually compiled into Android's binary XML format. That is why extracting the file with a normal archive tool is not enough; you need a decoder such as aapt, apkanalyzer, apktool, or a library that understands APK resources.

Why normal XML parsing fails

The manifest stores package metadata, activities, services, permissions, and SDK requirements. In the built APK, that manifest is not plain-text XML anymore, so a normal XML parser sees unreadable binary data.

You can confirm the file exists:

unzip -l app-release.apk | grep AndroidManifest.xml

That proves the file is present, but it does not decode it. The next step must use Android-specific tooling.

Use SDK tools for quick inspection

If you only need to inspect the manifest manually, Android build tools are the fastest route.

aapt shows a structured tree:

aapt dump xmltree app-release.apk AndroidManifest.xml

This is useful for quick terminal inspection, especially when you want to verify permissions, activities, or package names.

If you have apkanalyzer, the output is often easier to read:

apkanalyzer manifest print app-release.apk

You can also combine that with shell tools:

apkanalyzer manifest print app-release.apk | grep uses-permission

For one-off debugging, this is often enough. You do not need to write any parsing code at all.

Use a library for automation

If you need to inspect many APKs or build validation tooling, use a library rather than scraping terminal output. In Python, androguard is a common option.

pip install androguard

Then parse the APK structurally:

1from androguard.core.apk import APK
2
3apk = APK("app-release.apk")
4
5print("Package:", apk.get_package())
6print("Version name:", apk.get_androidversion_name())
7print("Version code:", apk.get_androidversion_code())
8
9print("Permissions:")
10for permission in apk.get_permissions():
11    print(" -", permission)
12
13print("Activities:")
14for activity in apk.get_activities():
15    print(" -", activity)

This is much easier to maintain than grepping aapt output if you need repeatable checks in CI or audit scripts.

If you need decoded XML text, you can get that too and then pass it to a regular XML library:

1from androguard.core.apk import APK
2import xml.etree.ElementTree as ET
3
4apk = APK("app-release.apk")
5xml_text = apk.get_android_manifest_xml().toxml()
6root = ET.fromstring(xml_text)
7
8print(root.tag)

The key point is that the XML parser only comes after Android-specific decoding, not before it.

Use apktool when you want a decoded project tree

If your goal is broader reverse engineering, apktool is very convenient because it decodes the manifest and resources into a directory.

apktool d app-release.apk -o decoded_apk

This is heavier than aapt or apkanalyzer, but it is useful when you want to inspect more than one field or compare manifests across builds.

Common Pitfalls

• Treating AndroidManifest.xml from an APK as plain-text XML immediately after unzipping it.
• Scraping verbose command output when a structured library would be easier for repeated automation.
• Forgetting that different Android tools present decoded manifest data in different formats.
• Using outdated Android SDK tools and then assuming the APK is malformed when decoding looks wrong.
• Ignoring package-relative class names that begin with a dot when building automation around components.

Summary

• The manifest inside an APK is usually binary XML, not normal readable XML.
• Use aapt or apkanalyzer for quick inspection from the command line.
• Use a library such as androguard for scripted parsing.
• Use apktool when you want a fully decoded directory, not just manifest fields.
• Decode first, then parse as XML if needed.
