Android App Development Roadmap

This roadmap shows the learning path from exploring Android via Termux to writing full apps using Python, C++, or official Android development tools.

Stage 1: Termux & Android OS Basics

Learn Android file system and directory structure
Use Termux commands: ls, cd, pwd, cat
Create scripts and simple aliases in .bashrc
Understand permissions, storage access, and sandboxing

Stage 2: Programming Fundamentals

Learn a language like Python or C++
Write small programs and scripts on your phone or PC
Practice input/output, variables, loops, functions, and basic file handling
Experiment with automating tasks via Termux scripts

Stage 3: Python Scripting on Android

Use Python in Termux or install Kivy/PySide for GUI experiments
Create small tools or automation apps for your phone
Learn how to run scripts, manage dependencies, and access Android storage

Stage 4: Advanced Development / Native Apps

Learn Java or Kotlin for native Android apps
Install Android Studio for app building and testing
Optionally, learn C++ for performance-critical parts (via Android NDK)
Package scripts or games into standalone APKs
Deploy and test apps on your phone

Stage 5: Continuous Learning

Explore advanced Android features: sensors, networking, databases
Experiment with GUI design, animations, and user experience
Optimize apps for performance and security
Publish apps if desired, or use them for personal automation

Key Takeaway: Each stage builds on the previous one. Termux → Programming → Scripting → App Development. The knowledge you gain now will make writing apps much easier in the future.
