I have a list of image in my xaml on pcl project when I test my app in my samsumg galaxy s5 device I do this: I enter in the page of the list, then I press the back button on the action bar...I do it many times...then, it happens:
System.NotSupportedException: Unable to activate instance of type Xamarin.Forms.Platform.Android.Platform+DefaultRenderer from native handle 0x20e0001d (key_handle 0x42433c30).
or
Unable to activate instance of type Xamarin.Forms.Platform.Android.LabelRenderer from native
Update
I added this script:
using System;
using Android.Runtime;
using Xamarin.Forms;
using Xamarin.Forms.Platform.Android;
[assembly: ExportRenderer(typeof(Xamarin.Forms.Label), typeof(LabelRenderer))]
namespace neoFly_Montana.Droid
{
/// <summary>
/// This renderer was added to resolve a bug that crashed the application in known case
/// Bug 36285 - Android App (Always) Crashes After Navigating Away From Page With A ScrollView In HeaderTemplate of ListView
/// <seealso cref="https://bugzilla.xamarin.com/show_bug.cgi?id=36285"/>
/// and
/// Bug 32462 - Crash after a page disappeared if a ScrollView is in the HeaderTemplate property of a ListView
/// <seealso cref="https://bugzilla.xamarin.com/show_bug.cgi?id=32462"/>
/// </summary>
public class LabelRenderer : Xamarin.Forms.Platform.Android.LabelRenderer
{
public LabelRenderer()
{ }
public LabelRenderer(IntPtr javaReference, JniHandleOwnership transfer): base()
{ }
}
}
the error still here
-------------------------------------- update
Then, I changed and Now my code is:
using System;
using Android.Runtime;
using Xamarin.Forms;
using Xamarin.Forms.Platform.Android;
using neoFly_Montana.Droid;
using Android.Content;
[assembly: ExportRenderer(typeof(Xamarin.Forms.Label),
typeof(NeoFly_MontanaLabelRenderer))]
namespace neoFly_Montana.Droid
{
public class NeoFly_MontanaLabelRenderer : Xamarin.Forms.Platform.Android.LabelRenderer
{
public NeoFly_MontanaLabelRenderer(Context context) : base(context)
{
}
}
}
then, I can see this error frequently.
System.NotSupportedException: Unable to activate instance of type neoFly_Montana.Droid.NeoFly_MontanaLabelRenderer from native handle

-----------------update------------ Now, it seems that the label renderer error doesn't occur anymore...but the default+renderer error still here...and a null reference exception as well (I think it's related with the constructor in my label renderer code)
