"java.lang.IllegalStateException: Cannot perform this action on a sealed instance." FATAL EXCEPTION: main

Question

I am getting this error on pre-launch report from playstore console. I am not able to generate this crash on any real device I try. The device from pre-launch report is Samsung s9 (Android 8.0).

This is the stacktrace :

Dont know how much its helps but I added webView.setAccessibilityDelegate(new View.AccessibilityDelegate()); this in my webview and the error went away from playstore. – Lowrie

Hi Bipin, where did you add this line? – Irving

Without seeing more code, I'd recommend looking through the following links to try and determine an exact cause.

https://mcmap.net/q/1373355/-java-lang-illegalstateexception-cannot-perform-this-action-on-a-not-sealed-instance

When updating values for AccessibilityNodeInfo it has been seen that calling .getClassName() to see if the value is NULL can help prevent this error.

Similar to the previous, If you are changing the text of an accessibilityNodeInfo you can check to see if it's sealed by calling isSealed(). on the AccessibilityNodeInfo object
