Exception when using Rg.Plugins.Popup in xamarin forms

Question

I have a list view populated in popup. I am using 1.0.4 version of

Rg.plugins.popup.

on selecting list item, I'm calling

PopupNavigation.PopAsync(true);

to close the popup.

but sometimes I'm getting below crash:

Android.Runtime.JavaProxyThrowable: Exception of type 'Android.Runtime.JavaProxyThrowable' was thrown. --- End of managed Android.Runtime.JavaProxyThrowable stack trace --- android.runtime.JavaProxyThrowable: System.IndexOutOfRangeException: There is not page in PopupStack at Rg.Plugins.Popup.Services.PopupNavigation.PopAsync (System.Boolean animate) [0x0000c] in :0 at TCRMobile.ViewModels.TicketsListGenericViewModel.OpenTicketTabsPage (TCRMobile.DataObjects.Ticket selectedTicket, System.Int32 mobileID, System.Nullable`1[T] laborMiscTimeMobileID) [0x00000] in :0 at TCRMobile.ViewModels.TicketsListGenericViewModel+<>c__DisplayClass13_0.b__0 () [0x00055] in :0 at TCRMobile.Droid.Services.DialogService+<>c__DisplayClass5_0.b__1 (System.Object sender, Android.Content.DialogClickEventArgs e) [0x0001d] in <5c6ae91b284846f5995b4e735df62b69>:0 at Android.Content.IDialogInterfaceOnClickListenerImplementor.OnClick (Android.Content.IDialogInterface dialog, System.Int32 which) [0x00012] in <1ccf2ea9504d42c08b47c05ee0c5e9f7>:0 at Android.Content.IDialogInterfaceOnClickListenerInvoker.n_OnClick_Landroid_content_DialogInterface_I (System.IntPtr jnienv, System.IntPtr native__this, System.IntPtr native_dialog, System.Int32 which) [0x0000f] in <1ccf2ea9504d42c08b47c05ee0c5e9f7>:0 at (wrapper dynamic-method) System.Object:d515a9d0-d793-4191-a5c6-5e450c1fd743 (intptr,intptr,intptr,int) at mono.android.content.DialogInterface_OnClickListenerImplementor.n_onClick(Native Method) at mono.android.content.DialogInterface_OnClickListenerImplementor.onClick(DialogInterface_OnClickListenerImplementor.java:30) at com.android.internal.app.AlertController$ButtonHandler.handleMessage(AlertController.java:175) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6682) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1534) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1424)

I assume crash is because some of my users double clicking the list item. Do I need to always check the popup stack count before calling

popasync(true).

If updating the above popup library would solve this issue?

please explain the reason for crash and solution.

Thanks

Just use a bool Clicked; as a reference if user click, clicked = true and have a check if user has already check then just return; — Luminous_Dev, Aug 13 '18 at 22:02

Try this Popup ViewPage.

                        <Image Source="{Binding IconClose}" x:Name="ImageClose" HorizontalOptions="End" VerticalOptions="Start"/>
                    </Grid>

    </StackLayout>
</pages:PopupPage>

This is the Navigation Part.

 protected override void OnAppearing()
        {
            base.OnAppearing();
            ImageClose.GestureRecognizers.Add(new TapGestureRecognizer
            {
                Command = new Command(_ =>
                {
                    PopupNavigation.Instance.PopAsync();
                })
            });
        }

Android

In MainActivity.cs file.

Rg.Plugins.Popup.Popup.Init(this, bundle);

IOS

In AppDelegate.cs file.

 Rg.Plugins.Popup.Popup.Init();

Try to this code.

And In Project Rg.Plugins.Popup 1.1.4.158-pre package is installed.

So updating this plugin and adding the above line in app delegate, does it close the popup fast or check to see itself if there are no popups in stack? — Sai Sunkari, Aug 20 '18 at 18:25

Probably this would be no brainer solution.

Call it

await PopUpService.PopUpAll();

Service

public static class PopUpService
{
    public static async Task PopUpAll()
    {
        if (Rg.Plugins.Popup.Services.PopupNavigation.Instance.PopupStack.Any())
        {
            await Rg.Plugins.Popup.Services.PopupNavigation.Instance.PopAllAsync();
        }
    }
}
