To Reproduce:

I only could log an error while I was debugging this problem, I think could be helpful

Uncaught Error: Extension context invalidated. at Object.value [as sendMessage] (polyfill.js:124) at HTMLDocument.<anonymous> (include.postload.js:683) value @ polyfill.js:124 (anonymous) @ include.postload.js:683

Solved: This was a problem with other library (dyscan) that was overriding the onActivityResult with the same requestCode than react-native-webview library.

I needed to modify the library and return a different code in the onActivityResult method.
