How to increase binded progress property in view model
Hello developers! 
I'm begginer in xamarin ,For some time i'm trying to implement a progress bar which will be increasing by tapping a image assing to it. My problem is that i can't figure out how to get access to Bindable property in my viewmodel. When i copied my model properties to viewmodel still no result, my dream solutions is that model's properties will stay in a model becouse i implement a observable object to this and create observable collection which is binded to listview in my page.xaml file. Can i ask you for some tips or guide my throught this step of my project ?
My code from ViewModel :
` public class SurfBoardViewModel : BaseViewModel
{
public ObservableRangeCollection Boards { get; }
public SurfBoardViewModel()
{
Boards = new ObservableRangeCollection<SurfBoard>
{
new SurfBoard()
{
Counter =0.2, Icon="icon.png"
},
new SurfBoard()
{
Counter= 0.1, Icon="icon.png"
},
new SurfBoard()
{
Counter =.8, Icon ="icon.png"
},
new SurfBoard()
{
Counter= .3, Icon="icon.png"
},
new SurfBoard()
{
Counter = 0.2, Icon="icon.png"
}
};
AddProgressCommand = new Command(AddProgress);
}
private void AddProgress()
{
}
public Command SetBusyCommand { get; }
public Command AddProgressCommand { get; }
//My last step was to copy property from model class and make it observable object to remain all functionality as it was but still no result 
public class SurfBoard : ObservableObject
{
public SurfBoard()
{
}
double counter;
public double Counter
{
get { return counter; }
set
{
if (SetProperty(ref counter, value))
{
Debug.WriteLine("Counter changed");
}
}
}
string icon;
public string Icon
{
get { return icon; }
set
{
if (SetProperty(ref icon, value))
{
Debug.WriteLine("Icon Changed");
}
}
}
}`
Code from page xaml
`
<ListView x:Name="listView" ItemsSource="{Binding Boards}" HasUnevenRows="True"
Margin="10">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>

Azure app service not handing control back over to app after successful sign-in.
So I have been trying to implement client authorization for the past few days, specifically with Xamarin Forms on android. My code is heavily based off of James Montemagno's tutorial: Personalized Experiences with Azure Mobile Apps Authentication -it is a Xamarin blow but I can't link due to restrictions.
I am currently having an issue where I get a successful sign-in page on the android web-browser (azure mobile app url with the browser displaying "You have successfully signed in - return to the website") using Google as the identity provider, however, the browser does not return flow back over to the app. I can hit the browsers back button however once back in the app, I am still not logged in.
This is my android manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="schemas[dot]android[dot]com/apk/res/android">
<uses-sdk android:minSdkVersion="20" />
<application android:label="BookDB.Android">
<activity android:name="com[dot]microsoft[dot]windowsazure[dot]mobileservices[dot]authentication[dot]RedirectUrlActivity" android:launchMode="singleTop" android:noHistory="true">
<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:scheme="bookdbase" android:host="easyauth.callback" />
</intent-filter>
</activity>
</application>
</manifest>
And this is the Android implementation of the IAuthetication interface which I call from my PCL.
public class Authentication: IAuthentication
{
public async Task<MobileServiceUser> LoginAsync(MobileServiceClient client, MobileServiceAuthenticationProvider provider)
{
try
{
var user = await client.LoginAsync(provider,"bookdbase");
Settings.AuthToken = user?.MobileServiceAuthenticationToken ?? string.Empty;
Settings.UserId = user?.UserId ?? string.Empty;
return user;
}
catch (Exception e)
{
e.Data["method"] = "LoginAsync";
// Xamarin.Insights.Report(e);
}
return null;
}
}
If anyone could shed some light on this or perhaps point me in the direction of help, that would be much appreciated.
thanks.
