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-toolsandobjectionpackages - ADB configured and device connected
- Target APK installed on device
Workflow
Step 1: Setup Frida Server on Android Device
# Check device architecture
adb shell getprop ro.product.cpu.abi
# Output: arm64-v8a
# Download matching Frida server from GitHub releases
# https://github.com/frida/frida/releases
# Push to device
adb push frida-server-16.…
