Android: log into website and preserve session/cookie using DefaultHttpClient

Question

I\'ve been through different tutorials and this website, but couldn\'t find a proper solution. On the other hand, I\'ve seen apps logging into websites and requesting further in

You can do it this way, though it's rather a workaround.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    WebView webv = (WebView)findViewById(R.id.MainActivity_webview);         
    webv.setWebViewClient(new WebViewClient(){
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
            }
    });

    String postData = FIELD_NAME_LOGIN + "=" + LOGIN +
            "&" + FIELD_NAME_PASSWD + "=" + PASSWD;

    // this line logs you in and you stay logged in
    // I suppose it works this way because in this case WebView handles cookies itself
    webv.postUrl(URL, EncodingUtils.getBytes(postData, "utf-8"));
}
