Developing Android Mobile Devices

Here’s a clean, end-to-end setup you can follow to turn any PC/Mac/Linux box into a full Android app development rig, from “nothing installed” to “build, run, test, sign, and publish”.

1) Check your machine meets the basics

  • OS & CPU (64-bit required):

    • Windows 10/11 (64-bit), macOS 12+, or 64-bit Linux.

    • RAM: 8 GB minimum; 16–32 GB recommended if you’ll use the Emulator a lot.

    • CPU: Recent Intel/AMD or Apple Silicon; virtualization enabled for fast emulators. Android Developers

  • Why it matters: Android Studio + Emulator are heavy; hardware acceleration gives big speedups. Android Developers

2) Install Android Studio (the official IDE)

  1. Download Android Studio and run the installer. Android Developers

  2. Follow the first-run wizard; let it install:

    • Android SDK

    • Android SDK Platform-Tools (adb/fastboot)

    • Android SDK Build-Tools

    • Android Emulator
      (You can always add/remove later in Tools ▸ SDK Manager.) Android Developers+1

Tip: Android Studio bundles a compatible JDK—no separate Java install needed for typical Android/Kotlin projects.

3) Configure essential SDK components

Open Tools ▸ SDK Manager:

  • SDK Platforms tab: install the latest stable Android SDK (e.g., Android 15 / API 35) plus whatever older APIs you need for testing.

  • SDK Tools tab: ensure Android SDK Platform-Tools, Build-Tools, Android Emulator, and (optionally) NDK (Side by side) and CMake for any C/C++ code. Android Developers+2Android Developers+2

4) Make emulators fast (hardware acceleration)

  • Windows: use the built-in VM acceleration (WHPX/AEHD). If you previously enabled Hyper-V and have issues, see the acceleration guide to ensure the Emulator uses the right backend. Android Developers+1

  • macOS: uses Apple’s Hypervisor.Framework automatically (great on Apple Silicon).

  • Linux: ensure virtualization (VT-x/AMD-V) is enabled in BIOS/UEFI. Android Developers

Create a device in Device Manager (AVD Manager) and choose a system image (x86_64 or arm64, matching your host). Android Developers

5) Set up a physical device (optional but recommended)

6) Command-line tools you’ll actually use

These install with the SDK and are handy in CI or power workflows:

  • adb (device & emulator control), fastboot (bootloader), sdkmanager/avdmanager (headless SDK & AVD install), bundletool (builds/play-tests App Bundles). Android Developers+1

7) Languages & UI toolkit

8) Build system

  • Android uses Gradle with the Android Gradle Plugin (AGP). Keep AGP & Gradle within supported version pairs (AGP major bumps require a Gradle bump). Android Developers+1

9) Create your first project (sanity check)

  1. New Project ▸ Empty Views Activity or Empty Compose Activity.

  2. Pick a Package name, Save location, Language: Kotlin, Minimum SDK (e.g., API 24+).

  3. Click Run on an AVD or your physical device.
    If it launches, your toolchain is good.

10) Testing & quality

  • Unit tests: JUnit. UI tests: Espresso / UI Automator. (Setup is part of standard templates in Android Studio.)

  • Lint & inspections: Android Lint is built in; run before releases.

11) App signing & release (Play-ready)

  • Android requires apps to be digitally signed. For Google Play, you should use Play App Signing (Google manages the app signing key; you keep the upload key). Configure in Play Console when you first publish. Android Developers+1

  • Upload format: Google Play expects .aab (Android App Bundle); Play generates per-device APKs. Play App Signing is required for new apps using AAB. Android Developers

  • Some Google APIs (e.g., Maps, Sign-In) need your SHA-1—get it from Play Console (if using Play App Signing) or via keytool/Gradle’s signingReport. Google for Developers

12) Target & minimum SDK (Play requirements in 2025)

  • For new apps & updates after Aug 31, 2025, Play requires targetSdk = 35 (Android 15) or higher (different rules for Wear/Auto/TV). Existing apps must target at least API 34 to remain available to new users on newer devices; extensions to Nov 1, 2025 were offered. Set this in module ▸ build.gradle(.kts). Android Developers+2Google Help+2

13) (Optional) Native code toolchain

If you need C/C++:

  • Install NDK (Side by side) and CMake from SDK Manager ▸ SDK Tools. Android Studio will place the NDK under …/android-sdk/ndk/. Android Developers+1

14) (Optional) Useful add-ons

  • Version control: Git (GitHub/GitLab/Bitbucket).

  • Cross-platform frameworks: Flutter or React Native devs still use the Android SDK, AAB signing, and Play requirements when targeting Android. Flutter Documentation+1
