Upgrade React Native and Adjust Memory Settings

Medium Risk

The SIGSEGV error indicates a segmentation fault, often caused by memory access violations. In React Native 0.59.10, there are known memory management issues, particularly on older Android devices like the Caterpillar S41 running Android 8.0. This can occur due to improper handling of native modules or insufficient memory allocation for JavaScript execution.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Upgrade React Native to a stable version

    Upgrade your React Native version to at least 0.60 or later, where many memory management issues have been resolved. This can be done by updating the package.json and running npm install.

    bash
    npm install react-native@0.60.0
  2. 2

    Increase JavaScript heap size

    Modify the Android project settings to increase the JavaScript heap size. This can help mitigate memory issues on devices with limited resources. Open the android/app/build.gradle file and add the following line under the 'project.ext.react' section.

    yaml
    project.ext.react = [enableHermes: false, jsBundleDir: "${projectDir}/../build/jsbundle", jsHeapSize: 512]
  3. 3

    Check for native module issues

    Review any custom native modules for memory leaks or improper memory handling. Ensure that all native modules are correctly managing their lifecycle and releasing resources when no longer needed.

    java
    // Example of releasing resources in a native module
@Override
public void onHostDestroy() {
    // Clean up resources
}
  4. 4

    Test on a physical device

    After making the changes, build and run the application on the Caterpillar S41 device to verify that the SIGSEGV error no longer occurs. Monitor the app's memory usage during operation.

    bash
    react-native run-android

Validation

To confirm the fix, monitor the application for any SIGSEGV errors during runtime. Additionally, check the memory usage of the app using Android Studio's profiler to ensure it is within acceptable limits.
