Using WebView setHttpAuthUsernamePassword?

Question

I\'m trying to do basic authentication to view a protected url. I want to access the protected url which looks like this:

http://api.test.com/userinfo/vid?=1

This is so silly. I hacked something together that worked for me, I hope it'll work for you too.

public class AuthRequestDialogFragment extends DialogFragment
{
    @InjectView(R.id.dauth_userinput)
    public EditText userinput;

    @InjectView(R.id.dauth_passinput)
    public EditText passinput;

    @OnClick(R.id.dauth_login)
    public void login(View view) {
        ((Callback) getTargetFragment()).login(userinput.getText().toString(), passinput.getText().toString());
        this.dismiss();
    }

    @OnClick(R.id.dauth_cancel)
    public void cancel(View view) {
        ((Callback) getTargetFragment()).cancel();
        this.dismiss();
    }

    public static interface Callback
    {
        public void login(String username, String password);
        public void cancel();
    }

    @Override
    public void onStart() {
        super.onStart();
        WindowManager wm = (WindowManager) getActivity().getSystemService(Context.WINDOW_SERVICE);
        Display display = wm.getDefaultDisplay();
        int width = display.getWidth();
        int height = display.getHeight();

        getDialog().getWindow().setLayout(width*2/3, height/5*2);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        View view = inflater.inflate(R.layout.dialog_authrequest, container);
        ButterKnife.inject(this, view);
        getDialog().setTitle("Authorization required");
        return view;
    }
}

And

And

public class WebViewFragment extends Fragment implements AuthRequestDialogFragment.Callback {

    @Override
    public void login(String username, String password) {
        Log.d(this.getClass().getName(), "Login");
        myWebViewClient.login(username, password);
    }

    @Override
    public void cancel() {
        Log.d(this.getClass().getName(), "Cancel");
        myWebViewClient.cancel();
    }

And the most important:

private class MyWebViewClient extends WebViewClient {
    private WebView myView;
    private HttpAuthHandler httpAuthHandler;
    private String host;
    private String realm;

    @Override
    public void onReceivedHttpAuthRequest(WebView view, HttpAuthHandler handler, String host, String realm) {
        AuthRequestDialogFragment authRequestDialogFragment = new AuthRequestDialogFragment();
        FragmentManager fragmentManager = ((getActivity()).getSupportFragmentManager());
        authRequestDialogFragment.setTargetFragment(WebViewFragment.this, 0);
        authRequestDialogFragment.show(fragmentManager, "dialog");
        this.httpAuthHandler = handler;
        this.myView = view;
        this.host = host;
        this.realm = realm;
    }

    public void login(String username, String password) {
        httpAuthHandler.proceed(username, password);
        myView = null;
        httpAuthHandler = null;
        host = null;
        realm = null;
    }

    public void cancel() {
        super.onReceivedHttpAuthRequest(myView, httpAuthHandler, host, realm);
        myView = null;
        httpAuthHandler = null;
        host = null;
        realm = null;
    }
}
