12. Android App Dev from Scratch — Live Coding

A practical live-coding series where we build real Android apps from scratch using Android Studio, Jetpack Compose, and AI-assisted development. Each stream focuses on implementing new features, improving app architecture, adding security layers, and exploring modern Android development workflows. Perfect for beginners and mid-level developers who want to learn Android by watching full real-time builds with clean explanations.

🔧 Full Android Reverse Engineering Workflow

A compact end-to-end workflow for unpacking, patching, rebuilding, installing, and analyzing Android apps using APKTool + Frida on a rooted emulator.

---

📦 1. Unpack & Rebuild APK (APKTool)

apktool d app.apk -o unpacked
apktool b unpacked -o app_patched.apk

---

🔐 2. Start Rooted Emulator (optional)

adb root

---

🧩 3. Push & Run Frida Server

adb push frida-server /data/local/tmp/
adb shell chmod +x /data/local/tmp/frida-server
adb shell /data/local/tmp/frida-server &

---

📲 4. Install Target APK on the Emulator

adb install fdroid.apk

---

🧰 5. Install Frida Tools (Host Side)

python -m venv new_venv
source new_venv/bin/activate
pip3 install frida-tools

---

🔍 6. Find the Target Process on the Emulator

adb shell
adb top

---

🎯 7. Run Frida Script (example: SSL pinning bypass)

frida -U -p <process_id> -l ssl-pin.js

▶️ Run Script from CodeShare

frida -U -n com.example.app -c codeshare/<script_name>
