Performing Dynamic Analysis of Android App

When to Use

Use this skill when:

• Static analysis results need runtime validation on an actual Android device
• The target app uses obfuscation (DexGuard, custom packers) that prevents effective static analysis
• Testing requires observing actual API calls, decrypted data, or runtime-generated values
• Assessing root detection, tamper detection, or anti-debugging implementations

Do not use this skill on production environments without authorization -- dynamic instrumentation can alter app behavior and trigger security alerts.

Prerequisites

• Rooted Android device or emulator (Genymotion, Android Studio AVD with writable system)
• Frida server installed on device matching the architecture (arm64, x86_64)
• Python 3.10+ with frida-tools and objection packages
• ADB configured and device connected
• Target APK installed on device
