Good Day All
The emoji's that are used on whatsup are Unicode characters judging from the high quality graphics that get displayed on the chat area and also on the text entry where a selected emoji is displayed before the message is sent. i would like to have a text entry that can allow me to put a png of emoji in an entry or custom entry control and also include text when text are there as depicted below

By linking an emoji library to your app, and using an emoji-enabled "edit text" control. Every language and every platform does this a bit differently, though. Here is how Android does it.

On my Desktop, this works fine...
- Plug USB Cable into Desktop Computer (This is USB Type A)
- Plug USB Cable into Android Phone (This is USB 2.0 Micro B)
Within ten seconds (normally sooner) Windows File Explorer sees my phone, and allows me to access it just like another drive with file folders, etc.
I do the exact same sequence on my notebook computer.
Fail.
Asking Google about this produces answers galore.
After the first N of those answers proved themselves wrong, I decided to ask here.
Make a friend ! Give me a clue as to why this fails.
Enhance your reputation exorbitantly ! Tell me how to fix this.

I have an existing sqlite database in the android project under Assets.
I use the following to copy the database to the application personal folder
public async Task<string> GetDBPathAndCreateIfNotExists()
{
string databaseName = "DBQDive.db3";
var docFolder = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
var dbFile = Path.Combine(docFolder, databaseName);
if (!File.Exists(dbFile))
{
FileStream writeStream = new FileStream(dbFile, FileMode.OpenOrCreate, FileAccess.Write);
await MainActivity.Instance.Assets.Open(databaseName).CopyToAsync(writeStream);
}
return dbFile;
}
The problem is that even after uninstalling the app from the phone
if (!File.Exists(dbFile)) ALWAYS find a database file and therefore never copies the new database because the database has been created by a previous installation.
How can I detect if this is the first time the app is run so I can delete the database before it should be copied over?

Just a guess, but when you reinstall the app, the allowBackup element in the manifest may be restoring your database.

Thanks for the hint - had nothing to do with the problem 
The issue was with precedence, I was creating a SQLite database in the DAL base class BEFORE copying over the existing DB.
new SQLiteAsyncConnection(FilePath);
This actually creates an empty database in that location and it was called prior to the copy from android.
Last major issue nailed before I can deploy to the UAT people Yah!!!

I am trying to implement a MVVM ContentPage with a ListView that needs to bind to populated generic list of XML model objects in a ViewModel but the binding fails. The code that is shown calls an API that does return a valid list of XML data. The same code works fine when the binding is done directly in the code behind of the XAML Xamarin contentpage by setting the ItemSource in the codebehind. As said, the problem only happens when trying to pass the ListView through the ViewModel assigned to the contentpage. I have stepped through the code in the ViewModel and the ListView is populated successfully but the binding just doesn't work. I have other controls that are on the page not shown that the model binding does work for but the only control that doesn't work is the ListView. The code is shown below:
ViewModel:
namespace RestDemo.ViewModel
{
public class ViewModel : INotifyPropertyChanged
{
public ViewModel ()
{
GetRequest();
}
List<XmlPizzaDetails> _objPizzaList;
public List<XmlPizzaDetails> ObjPizzaList
{
get { return _objPizzaList; }
set
{
if (_objPizzaList != value)
{
_objPizzaList = value;
OnPropertyChanged("ObjPizzaList");
}
}
}
public async void GetRequest()
{
if (NetworkCheck.IsInternet())
{
Uri geturi = new Uri("http://api.androidhive.info/pizza/?format=xml");
HttpClient client = new HttpClient();
HttpResponseMessage responseGet = await client.GetAsync(geturi);
string response = await responseGet.Content.ReadAsStringAsync();
ObjPizzaList = new List<XmlPizzaDetails>();
XDocument doc = XDocument.Parse(response);
foreach (var item in doc.Descendants("item"))
{
XmlPizzaDetails ObjPizzaItem = new XmlPizzaDetails();
ObjPizzaItem.ID = item.Element("id").Value.ToString();
ObjPizzaItem.Name = item.Element("name").Value.ToString();
ObjPizzaItem.Cost = item.Element("cost").Value.ToString();
ObjPizzaItem.Description = item.Element("description").Value.ToString();
ObjPizzaList.Add(ObjPizzaItem);
}
Progress = false;
}
}
}
}
XAML
Model Binding portion:
ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:xlocal="clr-namespace:RestDemo.ViewModel"
xmlns:local="clr-namespace:RestDemo"
xmlns:Views="clr-namespace:RestDemo.Views"
x:Class="RestDemo.XmlParsingPageBehavior">
<ContentPage.BindingContext>
<xlocal:ViewModel />
</ContentPage.BindingContext>
Grid Binding Portion
<Frame Margin="5, 5, 5, 5" Grid.Row="2" Grid.Column="1" BackgroundColor = "Cyan">
<ListView x:Name="PizzaListView" ItemsSource="{Binding ObjPizzaList}" Margin="5, 0, 5, 0" Grid.Row="2" Grid.Column="1" HorizontalOptions="FillAndExpand" HasUnevenRows="True">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid HorizontalOptions="FillAndExpand" Margin="0,0,0,0" Padding="20">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Label Text="{Binding Name}" HorizontalOptions="StartAndExpand" Grid.Row="0" TextColor="Blue" FontAttributes="Bold"/>
<Label Text="{Binding Cost}" HorizontalOptions="StartAndExpand" Grid.Row="1" TextColor="Orange" FontAttributes="Bold"/>
<Label Text="{Binding Description}" HorizontalOptions="StartAndExpand" Grid.Row="2" TextColor="Gray" FontAttributes="Bold"/>
<BoxView HeightRequest="2" Margin="0,10,10,0" BackgroundColor="Gray" Grid.Row="3" HorizontalOptions="Fill" />
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Frame>

Try removing the Frame and addition decorations and start with a basic LV
<ListView x:Name="PizzaListView" ItemsSource="{Binding ObjPizzaList}" >
You do not need the grid R/C in the listview 
Ah think I have got it - your List should be an ObservableCollection<>.

I have it working. Yes ObservableCollections are the way to go but generic Lists are fine as well. The problem is that when the Model is bound the WebService call has not completed so when the List property is bound it is still null. Even when updated at this point the ObservableCollection won't work because it has not been seeded. The solution is to seed the ObservableCollection, or List, on the Page's OnAppearing event and bind the ViewModel as the BindingContext in this event. My solution is below:
protected override async void OnAppearing()
{
var vm = new ViewModel.ViewModel();
if (vm == null)
return;
HttpClient client = new HttpClient();
HttpResponseMessage responseGet = await client.GetAsync(vm.Geturi);
string response = await responseGet.Content.ReadAsStringAsync();
var _objPizzaList = new ObservableCollection<XmlPizzaDetails>();
XDocument doc = XDocument.Parse(response);
vm.GetRequest(doc);
this.BindingContext = vm;
}

Using MVVM I have a fairly typical data entry form where the user selects a Site which, in the ViewModel, creates a new SiteRisks record and pre populates the ID fields, the user then selects a bunch of values from pickers.
A typical picker in XAML
<Label Text="Surface Conditions:"
Style="{StaticResource Label1Style}" />
<Picker Title="Select"
ItemsSource="{Binding SurfaceList}"
SelectedItem="{Binding SelectedSiteRisks.SurfaceID, Mode=TwoWay}"
ItemDisplayBinding="{Binding Surface}" />
Where SelectedSiteRisks.SurfaceID is the field on the object where the value will be stored. This works from the View > VM and the correct value is stored in the SelectedSiteRisks object but when I create a new SelectedSiteRisks object in the VM and preload the SelectedSiteRisks.SurfaceID the view does not reflect the changed value.
OR
Do I need to have a selecteditem for each picker and manually update the SelectedSiteRisks object.

I have a requirement where the user needs to enter a report, very structured, pick this, select that enter a value and it looks up related info etc.
The point is that the device will NOT be connected to the internet and will not have phone service (think fishing boat in the middle of the ocean), I think this rules out a web application as it will require a local database.
The app should be both android and apple accessible. Synching the databases to a central server should be trivial.
What platform would service this requirement.

any one help me code of prayer five time in android studio?

It doesn't quite work like that.
We do not do your work for you.
If you want someone to write your code, you have to pay - I suggest you go to Freelancer.com and ask there.
But be aware: you get what you pay for. Pay peanuts, get monkeys.
The idea of "development" is as the word suggests: "The systematic use of scientific and technical knowledge to meet specific objectives or requirements." BusinessDictionary.com[^]
That's not the same thing as "have a quick google and give up if I can't find exactly the right code".
So either pay someone to do it, or learn how to write it yourself. We aren't here to do it for you.

Although I had the idea of doing the same thing, in order to force my systems to prevent me from using them during the prayer time. But, somehow I could not finish it at all.
Anyhow, the best approach to solving this problem is using the Android Alarm system. Set an alarm in the device, and it will remind you, you can do that programmatically. Unlikely it is that your Android will know when it is the prayer time for you. So you will have to feed it yourself. Since we are able to do this programmatically, we can utilize an API or a service provider that gives the prayer time for a certain location. Then you can blend the time with the location APIs in Android, and receive the information about that time.
Lastly, just make sure to follow the time and offer the prayer. Good luck!
