I am getting a crash on some actions(navigating to a screen, open video player etc) in my react native app. I have logged the error in android stdio and it was as below:

A/libc: Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x20 in tid 8890 
    (RenderThread), pid 8833

The crash is resolved by setting below in Android Manifest

 android:hardwareAccelerated="false"

But my react-native-video player is now showing black screen after setting android:hardwareAccelerated to false and I think it is not the best way to resolve it.

I don't know why I am getting this crash. I would be thankful for any help.

• if the error should occur in android emulator, then test it on a real device. android emulators seem to have multiple isses with hardware acceleration. – rmunge Commented Jul 11, 2021 at 17:29
• Have you tried to clean the Gradle and generate the build? – Jignesh Mayani Commented Jul 13, 2021 at 6:24

• I am facing the same issue: I am using "realm": "^10.9.1", in a “React Native application” to save some “Feed Array” data in realmDB, before closing my application. – ArefinDe Commented Nov 1, 2021 at 9:28

Might be a duplicate: React Native - Null pointer dereference after navigating to/from a page containing multiple tweets embedded inside their own WebViews

My app was crashing when I was navigating away from a screen which was using react-native-webview inside it.

My solution:

Example:

    <WebView
      style={{ opacity: 0.99 }}
    />

Others used androidHardwareAccelerationDisabled={true}, but it didn't work for me and can also cause performance issues.

Example:

    <WebView
      androidHardwareAccelerationDisabled
    />

Link to github discussion where I found the solution: https://github./react-native-webview/react-native-webview/issues/811#issuement-570813204

I have faced the same problem; was using "realm": "^10.9.1", in a “React Native application” to save some “Task Data” in realmDB.

Previously I was using "React-Navigation 5x" which have a dependency on react-native-reanimated. Now I have upgraded my code to "React-Navigation 6x", and removed old react-native-reanimated package version 2.0.0-rc.2 .
