Dropbox login fails in android webview

Thanks Greg.

I want to proceed with this ticket. Below are the declarations of AuthActivity from Dropbox and my own LoadUrlActivity to render Dropbox URLs inplace of Browser. Also, you can find WebView initialization.

<activity
    android:name="com.dropbox.client2.android.AuthActivity"
    android:screenOrientation="sensorPortait"
    android:configChanges="orientation|keyboard"
    android:launchMode="singleTask" >
    <intent-filter>
        <!-- Change this to be db- followed by your app key -->
        <data android:scheme="db-exi3o02y0ss2wn5" />
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.BROWSABLE" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

<activity
    android:name=".activities.LoadUrlActivity"
    android:screenOrientation="sensorPortait"
    android:exported="true"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data
            android:host="www.dropbox.com"
            android:scheme="https" >
        </data>
    </intent-filter>
</activity>

webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webview.loadUrl(getIntent().getData().toString());
