Android Studio: \"GC overhead limit exceeded\" during pre-Dexing: How can I fix it without increasing `xms` and `xmx`?

Android Studio: Google JAR File Exceeds GC Overhead Limit

When encountering the error message "GC overhead limit exceeded" during pre-Dexing in Android Studio, it is imperative to investigate the underlying cause. Typically, this error arises due to insufficient memory allocation for the dexing process, particularly when using large JAR files.

In your case, raising the xms and xmx values in the Android Studio idea.vmoptions file has proven unsuccessful. This suggests that an alternative approach may be necessary.

One effective solution is to increase the heap limit for the dexing operation. This can be achieved by adding the following to the dexOptions block in your build.gradle file:

dexOptions {
    javaMaxHeapSize "4g"
}

By setting the javaMaxHeapSize property to a higher value (e.g., 4g), you increase the maximum heap size available to the dexing process. This should alleviate the memory constraints and allow your build to proceed successfully.

Remember that while this measure addresses the specific memory-related error, it is crucial to consider other factors that may be contributing to the issue. Reviewing your project structure, dependencies, and any potential memory leaks in your code can help ensure a stable and error-free build process.
