9 Tips to Boost Android Gaming Performance

Gaming applications are some of the most resource-intensive applications and thus pose some of the highest demands on performance factors such as frame rate, latency, and resource utilization. However, due to Android’s open ecosystem, there are challenges in accounting for the type of hardware, software versions, or configurations. However, by following the best practices outlined in this document, developers will be in a position to enhance the performance of their Android gaming apps. 

1. Optimize Screen Size Handling

Not all mobile games or even casino apps automatically adjust to different screen sizes, which can impact gameplay and performance. Given the diversity of Android devices, designing adaptable layouts is essential. Ensuring that your game’s interface adjusts smoothly to various screen sizes and orientations enhances user experience and maintains performance across devices.

Online casinos have been among the most adaptable screen-size gaming outposts, Android included. Since some players access them on their desktops/laptops while others use their smartphones, such websites are now the real trailblazers of gaming adaptability. A mobile-optimized online casino, such as FastSlots and similar iGaming endeavours, ensures a seamless gaming experience by dynamically adjusting its slot machine and table game interfaces to fit different screen sizes. This approach prevents graphical distortions, improves touch responsiveness, and maintains an immersive experience whether players use a smartphone or tablet.

For players, to ensure the best experience while playing on your Android device, try these tips:

• Use Full-Screen Mode – Many Android devices allow you to force apps into full-screen mode via Display Settings > Full-Screen Apps. This helps eliminate black bars or UI cropping.
• Adjust Display Scaling – If buttons or text seem too small, go to Settings > Display > Display Size and increase or decrease the scaling for better visibility.
• Rotate Your Device – Some games perform better in landscape mode, offering a more immersive experience with larger controls and better spacing.
• Disable Auto-Rotate (If Needed) – If a game’s UI doesn’t adjust well to rotation, locking your screen in one orientation can prevent accidental layout changes.
• Check In-App Display Options – Some mobile casino apps and games have built-in settings for adjusting screen size, resolution, or UI elements for an optimal experience.

By fine-tuning these settings, you can ensure your mobile gaming sessions run smoothly and look their best, no matter what Android device you’re using.

2. Optimize Rendering Performance

Use Efficient Graphics APIs

Efficient rendering is crucial for smooth gameplay. One of the best ways to achieve this is by leveraging the latest graphics APIs. Vulkan, for example, offers lower overhead and improved multithreading capabilities compared to OpenGL ES, making it a preferable choice for high-performance games. Additionally, reducing overdraw, where pixels are drawn multiple times, can prevent unnecessary GPU workload. 

Reduce Texture Memory Usage

Proper texture memory management is also essential. Compressed texture formats like ETC2 or ASTC help reduce memory usage without sacrificing visual quality, allowing the game to run smoothly even on lower-end devices.

Optimize Shaders

Shaders play a significant role in rendering, and optimizing them is vital for performance. Simplifying fragment and vertex shaders helps in reducing GPU strain. Precompiling shader programs can eliminate runtime compilation overhead, making the rendering process more efficient. For lighting, baked lighting should be used where possible, as it significantly reduces real-time computations, improving both rendering speed and energy efficiency.

3. Improve CPU and Memory Management

Optimize Game Loops

Avoid running expensive calculations every frame. Instead, update logic at fixed intervals.

Use delta time to ensure smooth animations across different frame rates.

Manage Threads Efficiently

Thread management also plays a vital role in maintaining smooth performance. Offloading non-UI computations to background threads using AsyncTask, HandlerThread, or Coroutine Dispatchers prevents the main thread from being blocked. Use ThreadPools to efficiently manage multiple background tasks.

Minimize Memory Leaks

Memory leaks can severely impact gaming performance, leading to crashes and slowdowns. Android Profiler is a valuable tool for monitoring memory usage and detecting leaks. Developers should avoid retaining references to large objects unnecessarily, especially activities and views. WeakReferences can be used where applicable, and calling recycle() on bitmaps when they are no longer needed helps free up memory.

4. Reduce App Size

A smaller app size leads to faster load times and better performance. Utilizing Android App Bundles allows for delivering device-specific resources, minimizing unnecessary data. Employing tools like the Android Size Analyzer can help identify and eliminate redundant assets, ensuring efficient resource usage.​

5. Implement Image and Video Optimization

Efficiently managing multimedia content is crucial. Using appropriate formats, such as PNG for graphics and JPEG or WebP for photos, ensures quality without excessive size. Techniques like lazy loading can defer the loading of images and videos until necessary, conserving memory and processing power.​

6. Enhance Offline Capabilities

Designing your game to function effectively without constant internet connectivity can improve performance. Implementing efficient data synchronization and caching strategies ensures that users have a seamless experience, even in low or no-network scenarios.​

7. Reduce Load Time and Improve Asset Management

Implement Asset Bundling

• Load assets dynamically instead of packaging everything in the APK.
• Use Android App Bundles (AAB) to deliver optimized assets per device.

Optimize Level Loading

• Implement asynchronous loading for assets and levels to prevent UI blocking.
• Use object pooling to reuse game objects instead of constantly creating and destroying them.

8. Improve Battery Efficiency

Games are known to drain battery life quickly, but optimizing CPU and GPU usage can mitigate this issue. 

Optimize CPU and GPU Usage

• Reduce unnecessary background processes and computations.
• Use Frame Rate Capping, for example, limit the game to 60 FPS where appropriate, to save battery life.

Manage Background Services Wisely

• Avoid keeping unnecessary background services running.
• Use WorkManager for scheduled tasks rather than running continuous background processes.

9. Take Advantage of Android Performance Tools

Android Studio provides powerful profiling tools that help identify performance bottlenecks. The Android Profiler allows developers to monitor CPU, GPU, and memory usage, ensuring that resource allocation remains optimal. By analyzing frame rates, developers can fine-tune rendering performance and make necessary adjustments.

StrictMode is another valuable debugging tool that helps detect performance issues related to UI thread activity. It identifies slow disk or network operations, allowing developers to optimize their code accordingly. By integrating these tools into the development process, performance issues can be identified and resolved early on.

Conclusion

In optimizing Android gaming performance, rendering, resources, and real-time performance are all factors that need to be considered. By adopting the following best practices, it will be possible to develop a game that is smooth, efficient, and enjoyable to play on a variety of Android devices. It will be crucial to keep on testing, profiling, and optimizing your game as there is a new entry in the mobile gaming market.
