# GDA (GJoy Dex Analyzer) > Windows-native Dalvik decompiler and Android analysis workbench written in C++ that opens APK, DEX, ODEX, OAT, JAR, AAR and class files without installation. Besides Java and Smali views with cross-references, renaming and comments, it identifies packers, deobfuscates and decrypts strings, tracks data flow and taint, solves paths, runs rule-based malicious-behaviour, vulnerability and privacy-leak scans, and can dump device memory or hook methods with Frida. Shell and server CLI modes, Python and Java scripting and a sample malware-triage agent skill expose the same analysis to scripts and agents. - Type: Tool - Targets: App - Category: Android tools - Relationship: Foundation tool - Sources reviewed: 2026-10-19 - Added to the catalog: 2026-10-19 - Original resource: - Primary source: - Catalog page: - Record JSON: - Chinese version: [简体中文](https://awesomerea.org/zh/resources/gda-android-decompiler/index.md) ## Requirements & limits - Releases are Windows-only zip archives; the latest, GDA 4.12 of 2026-04-07, adds shell and server CLI modes among fixes. The repository holds no decompiler source: the README says GDA is not an open-source project, at least in the short term, and the repository publishes the free binaries with open scripts, plugin examples, rule samples and colour themes. - The executable runs without setup. Dex-family inputs need no Java, while JAR, AAR and class files need a working Java runtime for the bundled dx tool. The README says GDA is protected with VMProtect and unpacks embedded adb, a gdump memory-dump helper and rule files into the user’s application-data folder, which some antivirus products flag; the author states it has no malicious behaviour. - The skills folder holds a gda-analyze skill in Claude Code’s format that drives a bundled GDA.exe through a Python wrapper to trace code, extract indicators and draft malware reports, plus a server-mode client and test script. Its output, like the built-in rule-based scans, needs manual confirmation. - LICENSE is Apache-2.0, and NOTICE says most of GDA is released under it, with adb and dex libraries taken from the Android SDK and AOSP; this conflicts with the README’s closed-source statement, so the binaries’ terms are unclear. Users supply the apps they analyze. ## Primary sources 1. 2. 3. 4. 5. 6. ## More in Apps - [APKLab](https://awesomerea.org/resources/apklab/index.md) · Tool - [Fernflower](https://awesomerea.org/resources/fernflower/index.md) · Tool - [Bytecode Viewer](https://awesomerea.org/resources/bytecode-viewer/index.md) · Tool - [Logic-Lens](https://awesomerea.org/resources/logic-lens/index.md) · Tool - [Android Security Toolkit](https://awesomerea.org/resources/android-security-toolkit/index.md) · Tool - [ilspy-cli: targeted .NET decompilation for agents](https://awesomerea.org/resources/akiselev-ilspy-cli/index.md) · Tool ## About this entry The description was reviewed against primary sources.
