APK Decompiler: jadx & apktool

Your Android reverse-engineering workbench, in your pocket.

Powered by the jadx and apktool engines, this app is built for developers and security researchers to read Java code, edit Smali and resources, then rebuild, sign, and export APKs directly on your phone—no computer needed.

Open installed apps or APK/XAPK files in this APK editor to decompile app code, study how an app works, inspect its resources or see what's changed between versions.

🔎 Decompile with the jadx engine

Use the jadx engine to decompile APKs into Java code. Syntax highlighting and code search help you explore classes, resources and AndroidManifest.xml to understand an app's internal architecture and logic.

🛠️ Decompile and rebuild with the apktool engine

Use the apktool engine to decode APKs into Smali and resources. Edit Smali, XML and other files, then rebuild an APK.

Sign with the built-in key or import your own signing key file.

🔬 Decompile and edit native SO libraries

Explore the native code inside Android apps with a built-in SO editor, disassembler and hex editor. Browse functions, read C-like pseudocode and jump to the matching assembly. Edit instructions, strings or binary data, then save changes directly to your project. Undo and redo help you refine each change—all on your phone.

📦 Decompile installed apps and APK/XAPK files

Choose installed system or third-party apps. Import APK/XAPK files from device storage or an SD card, including packages downloaded from the web. Work with Base APK and Split APK modules in supported packages.

📤 Export code and app packages

Export decompiled source code as a ZIP file, or use the APK extractor to save an installed app as an APK/XAPK. Choose where to save your files so you can find and use them later.

🧾 Inspect permissions, components and signatures

Use the APK analyzer to check permissions, components, signatures and package details. Browse the manifest and resources to get a clearer picture of an app.

↔️ Compare app versions

Compare two APK/XAPK versions to see what changed. Review package differences and include code or resource comparisons when you need a closer look.

🧩 Review and migrate project changes

Use saved baselines to review modified, added and deleted files. Migrate your edits to another APK/XAPK or an existing project.

🌐 Edit app text and translations

Change app names, button labels and messages. Add translations manually for other languages, then rebuild an APK with your updated text.

💾 Back up and restore projects

Save a project backup before making changes. Restore it later to return to a saved state and continue your work.

🧭 Get started in a few steps

1. Choose an installed app or an APK/XAPK file.

2. Open ""View source code"" for Java, or ""Modify APK / XAPK"" for Smali and resources.

3. Browse the results, export files, or build an APK after editing an apktool project.
