Resolving the CompressorException Error in React Native Android While Extracting TAR Files

If you've been working with React Native, particularly with the react-native-archiver library, you may have come across the frustrating error:

This error typically arises when trying to extract a TAR file in Android applications. In this post, we will explore the possible causes of this error and walk through the steps to resolve it effectively.

Understanding the Problem

Background

The error stems from the react-native-archiver library, which is commonly used for archiving and extracting files in various formats, including TAR and GZIP. In the context of your application, you are attempting to extract a TAR file located at a specified directory in the Android external storage.

Code Example

Here’s a snippet of the code you might be using to extract the TAR file:

Unfortunately, when executing this code, you ran into the CompressorException error, which stops the extraction process.

Solution: Fixing the Error

The solution to fix the CompressorException error involves a simple change in the underlying Java code of the react-native-archiver library.

Step-by-Step Guide

Locate the Java File: Navigate to the RNArchiverModule.java file. You can find this file in your project’s node_modules directory under the path:

Modify the Archiver Creation Line: In the RNArchiverModule.java file, look for the following line of code:

Change It to Remove Compression Type: Modify this line to simply create an archiver for TAR without specifying GZIP:

Why This Works

The original line of code was set to use compression (CompressionType.GZIP), which was unnecessary since you were dealing with a plain TAR file rather than a TAR.GZ file. By removing the compression type, the extraction process can proceed without trying to create a compressor input stream that doesn't exist in your context.

What Next?

While this change resolves the CompressorException error, it’s important to note that the react-native-archiver library currently does not support iOS. If you are also targeting iOS in your React Native application, you will need to seek an alternative approach for extracting TAR files or find a library that is compatible with both platforms.

Alternative Solutions to Explore

Look for Cross-Platform Libraries: There are several libraries out there that might offer broader support for both Android and iOS.

Implement Custom Extraction Logic: Depending on your requirements, you could also write custom code to handle TAR file extraction.

Conclusion

In summary, the CompressorException error in React Native while trying to extract TAR files on Android can be resolved by modifying the archiving code in the library itself. While it’s a straightforward fix, the lack of iOS support means that further investigation may be required for projects that aim to function on both platforms. This allows you to maintain a smoother workflow while developing your React Native applications.

Keep tweaking and improving your knowledge in React Native, and don't hesitate to share your experiences and solutions with the community!
