I have trouble with load page File.html. I want to load my map in html but emulator not shows. I got error :
" [INFO:CONSOLE(0)] "Not allowed to load local resource: file:///android_asset/HTMLPage1.html", source: data:text/html,chromewebdata (0) "
" I/chromium(11080): [INFO:CONSOLE(0)] "Not allowed to load local resource: file:///android_asset/webkit/android-weberror.png", source: data:text/html,chromewebdata (0) "
On emulator page shows "WebPage not available"
Xaml file:
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:Mapaht"
x:Class="Mapaht.Mapahet">
<WebView
x:Name="webviewjava"></WebView>
</ContentPage>
Page file
public Mapahet()
{
InitializeComponent();
webviewjava.Source = "file:///android_asset/HTMLPage1.html";
}
You are getting the WebView before setting the Content view so the wv is probably null.
protected override void OnCreate (Bundle savedInstanceState)
{
base.OnCreate (savedInstanceState);
SetContentView (Resource.Layout.webview);
WebView wv;
wv = FindViewById<WebView>(Resource.Id.webviewjava);
wv.LoadUrl("file:///android_asset/HTMLPage1.html");
}
}
You need to have permissions in AndroidMainfest.xml file that has access to the internet:
<uses-permission android:name="android.permission.INTERNET" />
I have trouble with load page File.html.
Doing the following steps and it works fine on my side :
XAML :
<WebView
x:Name="webviewjava"
HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand"
/>
Interface in your PCL :
public interface IBaseUrl
{
string Get();
}
Implement this interface in Android :
[assembly: Dependency(typeof(BaseUrl_Android))]
namespace FormsWebview.Droid
{
public class BaseUrl_Android : IBaseUrl
{
public string Get()
{
return "file:///android_asset/";
}
}
}
Load local resource file in Assets
folder :
public MainPage()
{
InitializeComponent();
var baseUrl = DependencyService.Get<IBaseUrl>().Get();
string Url = $"{baseUrl}local.html";
webviewjava.Source = Url;
}
