Xamarin.Forms SkiaSharp Gradient working on Android but not on iOS -


we need gradient on our pages, we're using skiasharp , gradientview. works fine on android isn't working on ios - gradient doesn't display.

do need ios-specific initialisation skiasharp on ios, renderers or code in appdelegate?

edit running on ipad ios 10.3.3. our xaml:

    <?xml version="1.0" encoding="utf-8" ?>     <contentview xmlns="http://xamarin.com/schemas/2014/forms"                  xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"                  x:class="myproject.xforms.controls.gradientview">     </contentview>

our xaml.cs

using skiasharp; using skiasharp.views.forms; using xamarin.forms;  namespace myproject.xforms.controls {     public partial class gradientview : contentview     {         public color startcolor { get; set; } = color.transparent;         public color endcolor { get; set; } = color.transparent;         public bool horizontal { get; set; } = false;          public gradientview()         {             initializecomponent();              skcanvasview canvasview = new skcanvasview();             canvasview.paintsurface += oncanvasviewpaintsurface;             content = canvasview;         }          void oncanvasviewpaintsurface(object sender, skpaintsurfaceeventargs args)         {             skimageinfo info = args.info;             sksurface surface = args.surface;             skcanvas canvas = surface.canvas;              canvas.clear();              var colors = new skcolor[] { startcolor.toskcolor(), endcolor.toskcolor() };             skpoint startpoint = new skpoint(0, 0);             skpoint endpoint = horizontal ? new skpoint(info.width, 0) : new skpoint(0, info.height);              var shader = skshader.createlineargradient(startpoint, endpoint, colors, null, skshadertilemode.clamp);              skpaint paint = new skpaint             {                 style = skpaintstyle.fill,                 shader = shader             };              canvas.drawrect(new skrect(0, 0, info.width, info.height), paint);         }     } }

maybe haven't installed nugets (both skiasharp , skiasharp.views.forms) ios project?

i copy-pasted code brand new app, , worked first time.

some other things may issue view height/width 0. or, dodgy case color transparent.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
