Google Forms file upload not working on Android TTMSFNCWebBrowser

[Sezgin_Ozhan]

Hi,

I’m using TTMSFNCWebBrowser in an FMX project to display a Google Form.

The form works correctly on Windows and iOS, including the file upload (image upload) question.
However, on Android, when the user taps “Browse” on the file upload field, nothing happens.

Some details:

• Platform: FMX + TTMSFNCWebBrowser

• Content: Google Forms

• File upload type: Google Forms “Upload file” question

• Behavior:

  • Windows: file upload works

  • iOS: file upload works

  • Android: tapping “Browse” does nothing

• No errors are shown

• The same form works correctly in Chrome on Android

Initially, I assumed this might be related to Android permissions (such as storage or media permissions).
However, even after testing with the relevant permissions enabled, the behavior remains the same tapping “Browse” still does nothing.

From my investigation, it seems that Google Forms uses the Google Drive Picker for file uploads, which may require Chrome-level integration and therefore may not be supported inside Android WebView.

Could you please confirm:

• Whether this is a known Android WebView limitation

• Or if TTMSFNCWebBrowser provides (or plans to provide) any workaround for Google Forms file upload on Android

Any guidance or confirmation would be greatly appreciated.

Best regards

Hi,

After some research it seems that it will require some changes in the Android WebView implementation. We’ll discuss here what can be done, stay tuned.

Hi,

We made modification to the Android WebView implementation as well as the FNCWebChromeClient.jar file so that the file picker is triggered automatically when the browser requests it. You can expect these changes in the next update.
