How to create your own game on Android via your phone: from idea to Google Play

Creating a mobile game on Android from a phone is a task that seems impossible only at first glance. In fact, modern smartphones are as powerful as many computers from 5 years ago, and special applications and cloud services allow you to develop games without a PC. In this article we will analyze the entire process: from choosing tools to publishing the finished game in Google Play.

The main advantage of developing on a phone is mobility. You can test the game on the same device where you create it, and make updates anywhere: in a cafe, in transport, or in the country. However, there are also pitfalls: a limited screen, lack of a physical keyboard and difficulties with debugging. We'll tell you how to get around them.

It is important to understand that complex 3D projects like Genshin Impact cannot be created on a smartphone, but 2D platformers, arcades or puzzles are quite possible. Even a popular game Flappy Bird was made in a few days on a simple PC, and a similar project can be repeated on a phone.

What tools are needed for development

The first thing you need is the right software. On Android several types of tools are available:

• 📱 Mobile IDEs —full-fledged development environments adapted for touch screens (for example, AIDE or DroidScript).
• 🎮 Game designers —visual editors with a drag-and-drop interface (GDevelop, Godot for Android).
• ☁️ Cloud platforms —remote servers where you can write code through the browser (Replit, GitHub Codespaces).
• 🔧 Auxiliary utilities —apps for drawing sprites (SketchBook), creating music (FL Studio Mobile) or testing (Termux).

For beginners, the best choice is constructors like GDevelop or Buildbox. They do not require knowledge of programming, but allow you to create games with physics, animation and even simple AI. data-i="57">and AIDE with support Java/Kotlin or Termux to work with Python And C++.

Don't forget about technical requirements:

• 📲 Smartphone with Android 9.0+ and no less 4 GB of RAM (for comfortable work with the IDE).
• 💾 Free space: minimum 2–3 GB (graphics projects take up a lot of space).
• 🔌 Charging or Power Bank — development quickly drains the battery.

⚠️ Attention: Some tools (for example, Unity or Unreal Engine) do not officially support development on the phone. Attempts to install them through Termux or emulators may lead to assembly errors or unstable operation.

Choosing an engine: comparison of popular solutions

The engine determines how quickly you can create a game and what capabilities the project will have. Let's look at the most affordable options for Android development on a phone:

For the first game it is better to choose GDevelop or Buildbox. They allow you to assemble a prototype in a few hours without going into programming. If you plan to develop as a developer, you should master AIDE or Termux s Python (library Pygame).

Important nuance: to publish on Google Play, the game must be compiled in the format .aab (Android App Bundle), and not .apk. Not all mobile IDEs support this format - check before choosing a tool.

Installing and setting up the environment. development

Let's look at the step-by-step installation using the example of GDevelop one of the most accessible tools for beginners.

1. Downloading APK
   

   Install GDevelop from Google Play or from the official website. For stable operation you will need Android 8.0+.

2. Creating a project
   

   When you first start, select New Project → Empty Game. For the test, you can take the template Platformer.

3. Configuring the interface
   

   Enable the mode Touch Controls in the settings (Project → Game Settings), since there is no mouse on the phone.

4. Export APK
   

   Go to Export → Android and wait for the build. The first export may take 10–15 minutes.

For AIDE the process is more complicated:

1. Install the application and download the template Android Game.
2. Connect the repository LibGDX (popular framework for games) via Git.
3. Configure Gradle for assembly (manual editing of files will be required).

⚠️ Attention: When exporting APK to GDevelop an error may occur "Keystore not found". This means that you need to generate a digital certificate. This can be done directly in the application or through Termux the command:

keytool -genkey -v -keystore mygame.keystore -alias mygame -keyalg RSA -keysize 2048 -validity 10000

Creating a simple game: step-by-step example

Let's look at creating a simple arcade game where the player controls a ship, collecting coins and dodging asteroids. We use GDevelop.

1. Level design

Add objects:

• 🚀 Ship — sprite with physics (Physics Engine 2.0).
• 🪙 Coins — static objects with a trigger "Collide with Player".
• 💥 Asteroids —objects with behavior "Move randomly".

2. Game logic

Create events (Events Sheet):

• 🔄 Ship movement:

  If Touch.IsPressed("Left") → Move Player Left
  If Touch.IsPressed("Right") → Move Player Right

• 💰 Collect coins:

  If Player.CollidesWith(Coin) → Add 10 to Score | Delete Coin

• 🛑 Game Over:

  If Player.CollidesWith(Asteroid) → Go to Scene"GameOver"

3. Testing

Run preview (Preview) and check:

• Whether the ship reacts to touches.
• Is the score calculated correctly.
• Are there any lags during collisions.

If the game is slow, reduce the number of objects on the screen or optimize sprites (for example, reduce the resolution from 1024x1024 to 512x512).

Optimization and testing before release

Before publishing, the game needs to be tested on different devices. Here's what to check:

• 📱 Performance: FPS should not drop below 30 (optimally - 60). Use GameBench for monitoring.
• 🔊 Sound: Music and effects should work without delays. Test with. headphones and speaker.
• 🎮 Control: Buttons should not be overlapped by system elements (for example, the navigation bar).
• 🌍 Localization: If the game is in Russian, check the encoding (UTF-8) to support the Cyrillic alphabet.

For testing on other devices:

1. Export APK and send to friends via Telegram or Google Drive.
2. Use Firebase App Distribution for organized testing (before 100 testers free).
3. Test the game on emulators (BlueStacks, Genymotion) with different versions of Android.

⚠️ Attention: If the game requires an Internet connection (for example, for a leaderboard), test it in conditions unstable signal. Many users play in transport, where the connection is interrupted. Add error handling like "No Internet Connection".

Publishing the game in Google Play

To upload a game to Google Play, you need to complete several steps:

1. Register a developer account
   

   Pay a one-time fee $25 (may vary) on the website Google Play Console. Use a map or PayPal.

2. Preparing materials
   

   You will need:

   • 📌 Icon (512x512, PNG, without transparency).
   • 📸 Screenshots (minimum 2, better 4–6 from different devices).
   • 🎥 Video preview (30 seconds, MP4 or WebM).
   • 📝 Description (in Russian and English, with keywords).

Moderation period is from 1 to 3 days. If the game is rejected, the reason will be indicated in the letter (for example, "Violation of Families Policy" for children's games without age rating).

⚠️ Attention: From 2023 Google Play requires indicating target audience And content type (for example, the presence of violence or gambling elements). False information may result in your account being blocked.

Promotion and monetization of the game

Even the best game will not become popular without promotion. Here are working methods:

• 📢 Social networks:
  • Create a game page in VK/Telegram and publish updates.
  • Record gameplay for YouTube Shorts or TikTok (use hashtags #indiegame, #androidgame).
• 🤝 Collaboration:
  • Invite streamers to play your game for a small reward.
  • Add the game to the catalogs of indie developers (IndieDB, itch.io).
• 💰 Monetization:
  • 📺 Advertising: Integrate AdMob (banners or rewarded videos).
  • 🛒 Purchases: Sell skins or additional levels through Google Play Billing.
  • 🎁 Donations: Add a link to Donation Alerts or Patreon.

For beginners, a hybrid approach is optimal: a free game with advertising + paid content. For example, the first ones 10 levels are free, and the rest are opened for 99 ₽.

Average CPM (cost of 1000 ad impressions) in AdMob for Russia - $1–$3If yours. the game will score 10,000 installations with 50% retention, you can earn $50–$150 per month.
