Android. How to get rid of double firing onPageFinished?

Question

Android

Hello. My problem is that in the following code, the onPageFinished function is called twice, which consequently causes startActivity(showMainPage) to run twice.

public class Authorization extends Activity {

    WebView mWebView;
    final String redirect_url = "https://oauth.vk.com/blank.html#access_token=";
    Intent showMainPage;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_authorization);
        mWebView = (WebView) findViewById(R.id.webView);
        showMainPage = new Intent(this, MainActivity.class);
        mWebView.setWebViewClient(new MyWebViewClient());
        mWebView.loadUrl(this.getIntent().getStringExtra("url"));
    }

    protected class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            super.shouldOverrideUrlLoading(view, url);
            view.loadUrl(url);
            return true;
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            if (url.startsWith(redirect_url)) {
                showMainPage.putExtra("url with token", url);
                startActivity(showMainPage);
                finish();
            }
        }
    }
}
