Understanding APK and OBB Updates: What Gets Updated and How to Know
When developers release updates for Android apps and games, the updates can affect various parts of the application, including the APK file, OBB files, and sometimes even the application’s database. An APK file, or Android Package Kit, is the primary file containing the executable code of the application. OBB files, or ObbSpace Bundle, are separate data files that are often used to store game assets, save data, and other important information. Understanding what gets updated can help users to better manage their devices and applications.
What is an APK Update?
An APK update typically includes a new version of the application’s executable file. This file usually contains all the necessary components that make up the application, including new features, bug fixes, and performance improvements. However, just because there’s a new APK update doesn’t mean the OBB files will be affected. Additionally, developers may choose to update the application’s icon, textures, or other graphical elements, but these are typically stored in the OBB files rather than the APK.
What is an OBB Update?
On the other hand, an OBB update involves modifications to the data files that the APK may or may not require. These files often store user-specific data, game assets, and other information necessary for the application to function properly. Developers may update the OBB files to include new levels, save game progress, fix bugs, or enhance the performance of the game. It’s important to note that the OBB files are only useful if the corresponding APK also supports them.
How to Know What Gets Updated
Mostly, it should be listed by app/game programmers in the Google Play Store changelog. Simply Googling the app name and “changelog” can help you find this information. However, users often won’t be aware of these changes unless they actively look for or install the update. For instance, if you notice that you can’t access certain features or that the application seems to be running slower, it could be due to an OBB update you missed.
What Happens When Only the APK is Updated?
In some cases, especially for games, only the APK may be updated, which can cause compatibility issues with the OBB files. For example, if the new APK requires an updated OBB file to function correctly, but you haven’t installed the corresponding OBB update, you may encounter errors or issues with the application. Similarly, if a new feature in the APK doesn’t work because it’s dependent on a specific OBB file, you may need to install the latest version of the OBB file to ensure the app works as intended.
What Happens When Only the OBB is Updated?
When only the OBB file is updated, it usually means the application developers are fixing bugs, adding new content, or improving performance for users who already have the latest APK version installed. However, if the OBB file is outdated, users may experience performance issues or bugs. For example, new levels or achievements may not be available, or the game may not function correctly. In such cases, users should ensure they have the latest version of both the APK and the corresponding OBB file to avoid these problems.
How to Find and Install Updates
To find and install updates for your apps and games, you can follow these steps:
Check the Google Play Store for any available updates. The store will prompt you to download and install updates when they are available.
Go to the app’s detail page and scroll down to the updates section. Here, you can see the changelog and download any available updates.
For games, if the update involves an OBB file, make sure to download and install both the APK and the corresponding OBB file from the Google Play Store. This will ensure that all necessary data is up to date and that the game will function correctly.
Some games may also provide in-game prompts or announcements when updates are available. Follow these prompts or announcements to ensure you have the latest version of the game and its associated files.
Conclusion
Understanding the differences between APK and OBB updates is crucial for maintaining the functionality and performance of your Android applications and games. By keeping both files up to date and regularly checking for updates, you can ensure that your apps and games run smoothly and provide the latest features and improvements.
