Unable to create layer for WebView, size 640x7040 max size 8192 color type 4 has context 1

I am using WebView inside ScrollView, and it is giving IllegalStateException on Samsung SM-J610F. It is working fine on the rest of the devices that I have tested this code on.

When I take out WebView out of ScrollView it works fine. But the problem is that I have other views below WebView and if I don't use ScrollView, the user will not be able to see those view.

In my case the error was Unable to create layer for RNCWebViewManager$f, size 1080x9661 exceeds max size 8192 and triggered a crash on Android 8 Samsung and Huawei devices.

Removing the parent ScrollView was not an option in my case because that was really needed.

Limiting the webview height to 2720 (DeviceSupported(8192)/3) fixed the issue.

This was the only workaround I found to keep the hardwareAccelerated true

I had also to pass overScrollMode={'never'} as webview prop.

Remove the webview out of the scroll view and place it individually. Also all the other views present add them inside of the Scrollview. This way your webview will be stable also, the users will be able to scroll and refer the other views. Also, the webview should be declared and implemented properly:

 wv = (WebView) findViewById(R.id.web_view);
        wv.setInitialScale(1);      //webview page matches the screen size.
        wv.getSettings().setLoadWithOverviewMode(true);
        wv.getSettings().setUseWideViewPort(true);
        wv.getSettings().setJavaScriptEnabled(true);
        wv.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);    //loads online website when no internet connection.
        wv.loadUrl("https://prajwalwaingankar.wixsite.com/nivala");

As per the above code, all the views are above of the webview and the webview covers up the rest of the remaining screen size using method
.setInitialScale(1);
