Android app data reset
I use SQLite database in my app. Everything worked fine up until recently. Now whenever I do new build from Studio on my Android device everything gets reset into a state that it was like several days ago. The same items are present and all changes that I did to them are lost.
Is there some way to fix this or clear this cache? Even if I remove app from device, Studio on next build inserts the save data.

How to create a service in xamarin.forms?
I want to create a application where i wanted to send message just after the call is disconnected. When the callee places a call and disconnects it, the message should automatically be sent from the application to the caller.The message content would be the text configured in the app itself. The call could be a miscall or complete call. How can i achieve this in xamarin.forms?

Image not being displayed [Xamarin.Forms][Syncfusion]
I am using Prism with Xamarin Forms with all the packages up to date. I am using SfRotator, SfNavigationDrawer etc. in my project but my issue is with the SfRotator. The images in the rotator are not being displayed. I have tried using the control which was not displaying any images. I moved to FFImageLoading which works outside the SfRotator but not inside. Also, if i put a inside the , or if i use a CachedImageFastRenderer, it throws a NullReferenceException
Following are the code snippets:
MainPage.xaml
<tabView:SfTabItem.Content>
<rotator:SfRotator.ItemTemplate>
</rotator:SfRotator.ItemTemplate>
</tabView:SfTabItem.Content>
MainPageViewModel.cs
public class MainPageViewModel : ViewModelBase
{
private List imageCollection;
public List ImageCollection
{
get { return imageCollection; }
set { SetProperty(ref imageCollection, value); }
}
public MainPageViewModel(INavigationService navigationService)
: base(navigationService)
{
Title = "Main Page";
ImageCollection = new List();
ImageCollection.Add(new OfferSection ("offer1.jpg", "1" ));
ImageCollection.Add(new OfferSection ("offer2.jpg", "2" ));
ImageCollection.Add(new OfferSection ("offer3.png", "3" ));
}
OfferSection.cs
public class OfferSection
{
public string Image { get; set; }
public string OfferId { get; set; }
public OfferSection(string image, string id )
{
Image = image;
OfferId = id;
}

Issue while opening Xamarin form from BroadcastReciever class
This is for tracking incoming and outgoing phone calls. I am pushing a Xamarin form in the application Navigation stack from BroadcastReciever class using following code:
var phoneAddPage = new SomePage();
Xamarin.Forms.Application.Current.MainPage = new NavigationPage(phoneAddPage);
The page is getting pushed properly as expected. Issue is the page is overlapped by Splash Screen when application is opened. The form is functioning properly, overlap is the only issue.

Xamarin Controls or C# Class (object) data storage
Hi All,
Just wanted to know where c# (list) class stored the data in which memory (RAM or ROM).
As far as I know, when object is created the space is allocated for it's member (Variable/Properties or function) and stored all the data in RAM. So is it possible to access that data outside scope.

Is it possible to have overtype functionality in Entry
Hi,
I would like my entry to behave in overtype mode. Like when you press insert key in windows, and the type, the letter that you type will replace the letters instead of appending in between of that. Is it possible to achieve something like that with Entry? Maybe by using a custom renderer or something like that?
Thank you for your insights.
BR,

What is the special formula or code word for xamarin in visual studio's settings to make it compile
My goodness the errors just don't stop coming...
So I was trying to get a screen shot for another issue I have with the way something displays in apple and how it displays in Android so I thought I would get a screen in apple and switch start up projects and get a screen shot in Android..and of course there are going to be errors...
I switched from apple back to android and I get errors... (why would I expect anything else...)
Any way can some one give me a clue of how I can configure this project so that can successfully debug without jumping through hoops.
Here is my error... I was simply trying to get a screen shot of the app in the android simulator.
As a side note... this worked just an hour ago... as I was running this in android sim before unloading the project so that I could get the apple project to work...and I guess this some how breaks the android project every time...
And ideas or tips would be helpful and I would be grateful. Thanks

Trying to display elements over a semi translucent background
I have a page with a background image on which I'd like to display elements with a semi-transparent background. For example, a StackLayout with some labels that has a white, but semi-transparent, background so the page's background image shows partially through. I had hoped this could be achieved by simply setting opacity on the VisualElement, but unfortunately setting opacity affects both foreground and background, so the text in the labels is dimmed. Not the effect I'm going after - I want the text bright and fully opaque.
How can I achieve this effect without dimming the foreground of the elements inside the stacklayout?
