Launch url from one activity on another activity

I've been trying to make a small WebView app that lets the user search and load websites within it.

Currently my code looks promising in terms of the structure and the reference used, but I have stumbled upon an error which I can't seem to fix. Ive been looking for solutions on how to parse data as a string from my MainActivity class EditText to the WebView on my WebActivity class.

So far I've had no luck, I've tried several websites and have researched more into this but I have no clue what's going on. I even looked up similar answers regarding my situation on StackOverFlow but nothing has worked for me.

This Is the error I'm getting:

This is the code in my MainActivity's onCreate method:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText searchInput = (EditText) findViewById(R.id.searchInput);
final String webUrl = searchInput.getText().toString();

searchInput.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_SEARCH) {
            Intent intent = new Intent(MainActivity.this, WebActivity.class);
            intent.putExtra("website", webUrl);
            startActivity(intent);
            return true;
        }
        return false;
    }
});

And this is my WebActivity code:

public class WebActivity extends Activity {

    String webUrl = getIntent().getExtras().getString("webUrl"); // error is coming from here, according the the error log.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_web);
        WebView webView = (WebView) findViewById(R.id.webView);
        webView.loadUrl("http://example.com" + webUrl);

        // webView.getSettings().setJavaScriptEnabled(true);

    }
}
