Successfully deploying an Android game involves more than just creating an APK. Many developers encounter confusion regarding the placement and installation of OBB files, especially after packaging their projects. If you’re wondering how to properly handle OBB files following the build process, this guide clarifies the steps and common issues faced during installation, ensuring your game runs smoothly on users’ devices.
When you package your mobile game with Unreal Engine or similar platforms, the process often generates an OBB file alongside the APK. This file contains additional game data that cannot fit into the APK due to size constraints. Understanding how to install and manage these files is crucial for a seamless user experience.
One common question is whether the OBB file is automatically installed or if additional steps are needed. Typically, when you transfer your APK to a device, the Android system expects the OBB data to be stored in a specific directory: `/sdcard/Android/obb/your.package.name/`. If the OBB isn’t properly placed, the game might fail to launch or crash during startup. To avoid such issues, ensure you correctly move the OBB file to this directory before launching the game.
In the development environment, you can enable certain settings to embed the OBB data within the APK itself. For example, in Unreal Engine, navigate to Project Settings > Android > Package game data inside .apk?. Enabling this option combines the game data into the APK, which simplifies distribution but limits the size to approximately 50MB due to Google Play restrictions. If your game exceeds this size, you’ll need to distribute the OBB separately and ensure it’s correctly installed alongside the APK.
It’s also essential to confirm that USB debugging is enabled on your device, especially when testing direct installations via ADB. Without USB debugging, installing large files or running certain commands may not work correctly, leading to installation failures. If you encounter issues with the application not installing or launching, verify that USB debugging mode is active in your device’s developer options.

A common obstacle for developers is installing games on devices running Android 9 or newer. Many users report that Android 9 disables the ability to install apps over USB by default, which can prevent testing if the OBB is missing or not correctly placed. As a workaround, ensure your device’s settings permit app installations from trusted sources, or use alternative methods like sideloading via SD card or using an authorized app store.
In cases where installation problems persist, double-check the file permissions and directory structure. The OBB file should be named according to the package name and placed in the correct directory. Misnaming or misplacing the data can cause the game to fail to recognize the OBB, resulting in errors during startup.
For more details on managing game data and ensuring compliance with platform requirements, consult the official Unity and Unreal Engine documentation and relevant developer resources. Additionally, understanding digital rights management and how it impacts game file distribution can be very helpful. For an in-depth overview, explore this resource on digital rights management.
