If you’re an Android developer, you’ve likely come across this frustrating error message at some point: “A failure occurred while executing com.android.build.gradle.internal.tasks.CompressAssetsWorkAction: Required array size too large”. Don’t worry, you’re not alone! This error can be a real showstopper, but fear not, because we’re about to dive into the world of Gradle and Android build processes to figure out what’s going on and how to fix it.
What’s Causing This Error?
The error message itself is quite cryptic, but don’t worry, we’ll break it down. When you build an Android app, Gradle is responsible for compiling and packaging your code into an APK file. The error occurs when the CompressAssetsWorkAction task, which is part of the build process, encounters an issue while compressing your app’s assets.
The “Required array size too large” part of the error message suggests that there’s an array somewhere in your app’s assets that’s exceeding the maximum allowed size. But what array? And where is it? That’s what we’ll explore next.
Common Causes of the Error
Before we dive into the solutions, let’s take a look at some common causes of this error:
- Large Image or Video Files: If you have massive image or video files in your app’s assets, they can cause the array size to exceed the maximum limit. Think high-resolution images, 4K videos, or large audio files.
- Too Many Assets: Having an excessive number of assets in your app can also lead to this error. This might include numerous PNGs, SVGs, or font files.
- Invalid or Corrupted Assets: Sometimes, a single corrupted or invalid asset can cause the error. This might be due to a faulty upload, incorrect file format, or even a typo in the asset’s name.
- Gradle Configuration Issues: Misconfigured Gradle settings or incorrect dependency versions can also lead to this error.
Solutions to the Error
Now that we’ve identified some common causes, let’s dive into the solutions:
Solution 1: Optimize Your Image and Video Files
If you suspect that large image or video files are causing the issue, try the following:
- Compress Images: Use tools like TinyPNG or ImageOptim to compress your images, reducing their file size without sacrificing quality.
- Resize Videos: Use a video compression tool like FFmpeg or Handbrake to reduce the size of your video files.
Solution 2: Remove Unused Assets
If you have an excessive number of assets, try the following:
- Audit Your Assets: Review your app’s assets and remove any unused or unnecessary files.
- Split Assets into Multiple APKs: If you have a large number of assets, consider splitting them into multiple APKs using Android’s APK splitting feature.
Solution 3: Validate Your Assets
If you suspect that an invalid or corrupted asset is causing the issue, try the following:
- Verify Asset File Names and Formats: Double-check that your asset file names and formats are correct and consistent.
- Check for Corrupted Files: Use a tool like File Explorer or the command line to verify that your assets are not corrupted.
Solution 4: Update Your Gradle Configuration
If you suspect that your Gradle configuration is causing the issue, try the following:
- Update Your Gradle Version: Ensure you’re using the latest version of Gradle.
- Check Your Dependency Versions: Verify that your dependency versions are up-to-date and compatible with your Gradle version.
- Configure Your build.gradle File: Review your build.gradle file for any incorrect or outdated configurations.
Solution 5: Increase the JVM Heap Size
In some cases, increasing the JVM heap size can help resolve the issue:
org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
Add the above configuration to your `gradle.properties` file to increase the JVM heap size.
Conclusion
That’s it! By following these solutions, you should be able to resolve the “A failure occurred while executing com.android.build.gradle.internal.tasks.CompressAssetsWorkAction: Required array size too large” error. Remember to:
- Optimize your image and video files
- Remove unused assets
- Validate your assets
- Update your Gradle configuration
- Increase the JVM heap size (if necessary)

Frequently Asked Question
Get the answers to the most frequently asked questions about the “A failure occurred while executing com.android.build.gradle.internal.tasks.CompressAssetsWorkAction Required array size too large” error!
What causes the “A failure occurred while executing com.android.build.gradle.internal.tasks.CompressAssetsWorkAction Required array size too large” error?
This error occurs when the Android asset compression task reaches the maximum allowed array size in Java, which is 2^31-1 elements. This can happen when you have a large number of assets in your project, or when individual assets are extremely large.
How do I fix the “A failure occurred while executing com.android.build.gradle.internal.tasks.CompressAssetsWorkAction Required array size too large” error?
One solution is to increase the Java heap size by adding the following line to your `gradle.properties` file: `org.gradle.jvmargs=-Xmx4096m`. This increases the heap size to 4GB, which may be sufficient to compress your assets. If you still encounter issues, try increasing the heap size further or reducing the number of assets in your project.
Can I ignore the “A failure occurred while executing com.android.build.gradle.internal.tasks.CompressAssetsWorkAction Required array size too large” error?
No, it’s not recommended to ignore this error. Asset compression is an important step in the Android build process, and skipping it can result in issues with your app’s performance and compatibility. Instead, take the time to address the root cause of the error and ensure that your assets are properly compressed.
How can I reduce the size of my assets to avoid the “A failure occurred while executing com.android.build.gradle.internal.tasks.CompressAssetsWorkAction Required array size too large” error?
You can reduce the size of your assets by using image compression tools like TinyPNG or ImageOptim, or by removing unnecessary assets from your project. You can also consider using vector graphics instead of raster images, which tend to be smaller in size.
Will the “A failure occurred while executing com.android.build.gradle.internal.tasks.CompressAssetsWorkAction Required array size too large” error affect my app’s performance?
Yes, if you don’t address this error, your app may experience performance issues or even crashes due to the large size of your uncompressed assets. Compressing your assets is essential for ensuring that your app loads quickly and efficiently on a wide range of devices.
