TWebbrowser & camera permission

[John van de Waeter 4]

Hi all,

If I open a website that gives the user the opportunity to use the camera, nothing happens inside the TWebbrowser. No error thrown.

 

I manually granted the required permissions to the app, but no luck.

 

On iOS it works OK, on Android nothing happens.

 

Any ideas?

 

thanks,

John

The process on Android is to:

 

Check the checkbox for Camera permission in the Uses Permissions of the Project Options

 

Request the permission at runtime, e.g:

  PermissionsService.RequestPermissions(['android.permission.CAMERA'],
    procedure(const APermissions: TClassicStringDynArray; const AGrantResults: TClassicPermissionStatusDynArray)
    begin
      if AGrantResults[0] = TPermissionStatus.Granted then
        // Permission was granted
    end
  );

Thanks Dave.

It was my impression that the embedded webbrowser would need the permission.

The website with the photo-button works in every browser. The camera is started.

When the website is opened in the TWebbrowser, the photo-button only offers the option to pick a photo from the gallery.

Can you give an example of a site where it does this?

I'm trying to wrap "www.trustroots.org" into a TWebbrowser.

You would have to create an account to get to the profile/image page. It offers 2 buttons: Select a photo and Take a photo.
Works okay in a browser

Works okay in a TWebbrowser on iOS

Does NOT work in a TWebbrowser on Android.

After a bit of experimenting and searching around, it appears it's currently not possible. Here is one link relating to the issue:

 

  https://bugs.chromium.org/p/chromium/issues/detail?id=669492

 

I expect you'll need to implement photo taking in the app itself, and then when the user taps "Select Photo" or "Take A Photo" link in the TWebBrowser, they'll be able to select the image that has been taken.

The bugreport on Chromium is from 2016 and does not seem to be solved yet.
So yes, the only option is to implement taking photos in the app itself.

 

Thanks for looking into it!

However, another volunteer started a similar project (Website in a Webview) in another developers environment (react native IIRC) a couple of years ago.

Unfortunately this developer is no longer among us, but the app still exists in the Playstore.
Instead of doing nothing, both buttons show a choice: Camera or Files.

I would think (but am not sure) that this Webview also uses the Chromium browser. Strange that the reponse to the buttons is different...
