WebView: Why GET param as nested url not escaped?
<p>I have 2 apps: iOS &amp; Android, </p>

<p>i have WebView, in WebView i render Facebook auth dialog, so, when i press Login button - i see, that Android WebView generate invalid url:</p>

<p>Android:</p>

<pre><code>https://m.facebook.com/login.php?fbconnect=1&amp;skip_api_login=1&amp;m=m&amp;next=https://m.facebook.com/dialog/permissions.request?_path=permissions.request&amp;app_id=329216907114105&amp;redirect_uri=http%3A%2F%2Fapi.quickblox.com%2Fauth%2Ffacebook%2Fcallback&amp;display=touch&amp;response_type=code&amp;state=54b3e28cb55047afc2832cee42c16a748272b472.users.xml&amp;perms=email&amp;fbconnect=1&amp;from_login=1&amp;client_id=329216907114105&amp;refsrc=http://m.facebook.com/login.php&amp;app_id=329216907114105&amp;cancel=http://api.quickblox.com/auth/facebook/callback?error_reason=user_denied&amp;error=access_denied&amp;error_description=The+user+denied+your+request.&amp;state=54b3e28cb55047afc2832cee42c16a748272b472.users.xml&amp;landing_serial=1&amp;refid=9

<p>iOS:</p>

<pre><code>https://m.facebook.com/login.php?fbconnect=1&amp;skip_api_login=1&amp;m=m&amp;next=https%3A%2F%2Fm.facebook.com%2Fdialog%2Fpermissions.request%3F_path%3Dpermissions.request%26app_id%3D329216907114105%26redirect_uri%3Dhttp%253A%252F%252Fapi.quickblox.com%252Fauth%252Ffacebook%252Fcallback%26display%3Dtouch%26response_type%3Dcode%26state%3Dbcd9407a04d875d9eb2c4e8c84364de06b2249d1.auth.xml%26perms%3Demail%26fbconnect%3D1%26from_login%3D1%26client_id%3D329216907114105&amp;refsrc=http%3A%2F%2Fm.facebook.com%2Flogin.php&amp;app_id=329216907114105&amp;cancel=http%3A%2F%2Fapi.quickblox.com%2Fauth%2Ffacebook%2Fcallback%3Ferror_reason%3Duser_denied%26error%3Daccess_denied%26error_description%3DThe%2Buser%2Bdenied%2Byour%2Brequest.%26state%3Dbcd9407a04d875d9eb2c4e8c84364de06b2249d1.auth.xml&amp;landing_serial=1&amp;refid=9

<p>So Android not escaped nested param <strong>next</strong> as URL  -  and i get "error occurred. Please try again later."</p>

<p>So, what i must do, i want that Android generate right url...</p>

<p><strong>upd:</strong>
i get this url in WebView callback onPageStarted</p>
