hey @HirakCTS could you provide a minimal project, and steps to reproduce the Accessibility talk back for Android.

if you can give me this, I can go about debugging your issue.

Also, are you able to check if the issue remains after you have updated to latest, as well as latest xamarin forms

[HirakCTS]

@LuckyDucko I am using prism for popups. I have also raised issue with them and xamarin as well, but unable to find solution. Also, I am using latest version of xamarin and all the related libraries.

Please refer this

I appreciate you going through the effort with this.

In the sample app, it seems that focus isn't moving onto the popup page, but instead remaining on the page behind.

However, if you are able to tap on a UI element within the popup page that has no interact-able UI elements underneath, then the talkback correctly focuses on the popup view only.

i'll investigate more when I can, however, it seems that the error is due to the talkback getting confused on what page 'Context' it should be reading from.

I am seeing this same issue, using Rg.Plugins.Popup 1.2.0.223 and Xamarin.Forms 4.8.0.1451.
Problem occurs on Android with TalkBack, and on iOS with VoiceOver. I haven't seen the same problem on UWP.

Hi @LuckyDucko - also seeing this issue. Is there any workaround?

[LuckyDucko]

@WilliamWatterson86 I haven't looked at this in a while, and I'm unsure how to go about it fixing it to be honest.

To be clear, do you get it with the latest version?

[WilliamWatterson86]

Thanks @LuckyDucko. Yes I updated today and it still happens. I only see it on android, iOS seems ok.

I made a bit of a hack today and check if voice over is on and if it is I set the page that would be in the background to IsVisible false when navigating to the popup page, then back to true when I navigate back. So this hides the background page and so the elements aren’t selectable anymore. Looks a bit odd when the page in the background disappears but I think it’s fine as a temp workaround.

@WilliamWatterson86

Were you having issues with iOS in anything below say, version 2.0.0.5?
Recently we have been doing some fixes around that for iOS, and if it seems to have 'fixed' itself on iOS now, then perhaps we can look into doing some sort of similar touch ups on android

[WilliamWatterson86]

@LuckyDucko - I have just tried it with 2.0.0.4, and it seems to work fine with that version too. So unless the fix was before that?

[LuckyDucko]

@WilliamWatterson86 it was just a shot in the dark, it could be one before that aswell, or it could be fixed through xamarin/new version of iOS.

Still have android to work out though

Hi, I'm experiencing the same issue and I don't think Xamarin Forms will fix this since it's specific to popups. We're using your plugin because Xamarin doesn't support this feature. So I do think it has to be fixed here. iOS works fine, Android does not.

Since a lot of apps in Europe will have to comply to accessibility features by law, we are looking for workarounds or other plugins. Would be great if it could be fixed.

Edit: for now I'm trying the hacky workaround by @WilliamWatterson86

@McFlemchSoda

I'm sorry I haven't dedicated time to this, keeping up with projects can be time consuming.

if you, or anyone else, could provide a quick zip project with the following that would be helpful.

1. an example of the talkback not working on android.
2. the same sample working on iOS.
3. a short video showing it fail. Something tiny, you can upload direct to this issue

Then I can swap out the nuget for the rg project, and begin debugging. I may be able to work out a fix. if you can figure out which version of iOS it started 'working' with, that would be helpful in figuring out if android can also have the same fix
