HTML login form works in Android browser and fails with WebView ?

 Hi all,

I'm facing the following problem. I'm opening Flickr HTML login form
with default Android browser and everything works fine when I'm
logging (click "sign in" button in HTML form):
 String url = " http://m.flickr.com/" ;;
 Intent intent = new Intent();
 intent.setAction(Intent.ACTION_VIEW);
 intent.setData(Uri.parse(url));
 startActivity(intent);

But "sign in" button does nothing when using the same in a WebView:
String url = " http://m.flickr.com/" ;;
 WebView webview = (WebView) findViewById(R.id.flickr_authwebview);
 webview.getSettings().setJavaScriptEnabled(true);
 webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
 webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
 webview.getSettings().setLoadsImagesAutomatically(false);
 webview.setClickable(true);
 webview.loadUrl(url);

What could be the problem ?

 To get the login form, use:
String url = " http://m.flickr.com/signin/" ;;

Hi,
WebView requires that your manifest has:
<uses-permission android:name="android.permission.INTERNET"></uses-
permission>

HTML login form works in Android browser and fails with WebView ?

by Derek » Wed, 04 Mar 2009 04:49:49 GMT


 eah, thanks ! I was using layout_weight="1.0". I've removed it and
now the links are working. However, the login form still doesn't work
as in Android browser.
When I look to the source it seems very simple (No JavaScript). Some
form fields are hidden and empty. Could it be the problem ?

Here is my XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">

<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/flickr_authwebview_title_label"
android:layout_marginBottom="6px"/>

<LinearLayout android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center">

<Button android:id="@+id/flickr_authwebview_button_ok"
android:text="@string/flickr_authwebview_ok_button"
android:layout_marginRight="10px"
android:layout_marginTop="6px"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

<Button android:id="@+id/flickr_authwebview_button_cancel"
android:text="@string/flickr_authwebview_cancel_button"
android:layout_marginLeft="10px"
android:layout_marginTop="6px"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

</LinearLayout>

<WebView
android:id="@+id/flickr_authwebview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>

</LinearLayout>

and my code:
String url = "http://m.flickr.com/signin/";
WebView webview = (WebView) findViewById(R.id.flickr_authwebview);
webview.setWebViewClient(new AuthWebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
webview.loadUrl(url);
webview.setClickable(true);
webview.requestFocus();


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

Thanks for any help.

HTML login form works in Android browser and fails with WebView ?

 hanks but the problem is still here. However, If i remove:
webview.setWebViewClient(new AuthWebViewClient());
then I notice that with setSupportMultipleWindows(true); it opens a
new Android browser windows when I click to "Submit" button but the
page displayed is not the correct one. I'm wondering if Flickr is able
to check that the HTML is loaded into a WebView or a real browser (as
for in iFrame). I don't see how because there is no JavaScript in the
HTML.

Any other suggestions ?

 es, that's I did in the code I've posted before. I don't see the
difference ?
Could this issue come from Cookie management in WebView ? Is there any
option to make sure cookies are passed ?

Thanks.

2. WebView in 1.5 loading pages in Browser app instead of in my app

Hi there!
   So, I have this app that has a WebView object in it and basically I
used it to display websites within my app. In the previous SDK, this
works fine, the websites would appear from within my app. Now, when I
upgrade to 1.5, new websites are loaded in the Browser application
instead! Is there a way to stop this from happening?

Kenn.
