I have a question thta keeps occuring and i was wondering how to fix it. I want to be able to interact with views, in this case specifically the webview from outside the oncreate so that my methods can interact with the webview defined in the oncreate.
Here is an example of what im trying to do. In the search voice array im checked to see if the user said “go” and if they did i want either the go button to be pressed or to simply execute the code that the go button would do. I hope i explained this well enough, if you need clarification please let me know, thanks in advance!

Then, declare webview outside
onCreate:
