Crash when an external link cannot be opened by any app

[jim-daf]

WebPageFragment shows a page in a WebView, and its FragmentViewClient.shouldOverrideUrlLoading sends every link that is not the home page to an external app with startActivity(Intent(Intent.ACTION_VIEW, url)). The call is not guarded, so a link that no installed app can open throws ActivityNotFoundException and crashes the app.

On a device with no browser, or with a link whose scheme nothing handles, tapping the link closes the app.

Catching the failure and showing a short message would keep the app running. Links still open in their app when one is available.

@jim-daf while we welcome contributions from the community, I'm struggling to see a realistic case where there would be a URL that "no installed app can open". Surely any device that can install CycleStreets would always have a native web browser app?

Also, this comes across as something you've discovered via an AI tool scanning; FYI, you will generally find maintainers more receptive to submissions if you disclose such usage openly.
