JADX GUI Features Overview

JADX GUI Features Overview

Prerequisites

• JADX GUI (any recent release)
• An APK, DEX, JAR, AAR, or ZIP loaded via File → Open

Go to Declaration

Jump to the definition of a class, method, or field.

Methods:

• Ctrl+Click on any identifier in the code view
• Right-click → “Go to declaration” context menu

Behavior:

• Works for classes, methods, and fields across the entire decompiled codebase
• In AndroidManifest.xml, only Double-Click or Ctrl+Click is supported; keyboard shortcut D does not apply there

Find Usage

Find all references (cross-references) to a class, method, or field.

Trigger: Press X on any identifier, or right-click → “Find Usage”

Output: Opens a search results panel listing every call site and reference location.

Jump to Class from AndroidManifest.xml

Clicking a class name inside AndroidManifest.xml navigates directly to that class’s decompiled source.

Constraint: Only mouse-based navigation (Double-Click / Ctrl+Click) is supported; keyboard shortcuts are not.

Switch Line Number Mode (Simple / Debug)

Toggle between two line display modes in the code editor.

Trigger: Click the line number gutter area on the left side of the editor.

Modes:

• Simple — shows sequential line numbers matching the decompiled Java output
• Debug — shows original bytecode line numbers, useful for correlating with stack traces and debugger breakpoints

Package Exclusion

Exclude an entire package from decompilation, search indexing, and memory usage.

Methods:

1. Package tree — Right-click a package node in the left-hand tree → “Exclude”
2. Preferences — Add exclusion patterns via Ctrl+Shift+P → Exclusions tab

Effect:

• All classes inside the excluded package are skipped during decompilation
• Excluded classes do not appear in search results
• Reduces memory consumption, useful for large APKs with third-party libraries that are not of interest
