I have a HTML file stored on the memory card of my Android phone. I can open it in my browser (Chrome) but cannot bookmark it -- the URL is content://com.google.android.blah.blah... (I was expecting file://...) and appears to expire after some time.
Howe can I get a permanent bookmark to a local file?
I had the same problem after upgrading to Android 10. I used to be able to set a bookmark in FireFox even after upgrade. That stopped working as well.
The only solution I have found is to use a HTML Reader. Here is a link to one I have found to work well. https://play.google.com/store/apps/details?id=in.vineetsirohi.htmlreader
file:///storage/emulated/0/...?file://protocol only works for certain directories on Android 10+, see Local files revisited: Opening local HTML files (file:///path/to/file) in Chrome on Android 10.xcontent://. That means it's accessing a content provider. Is that from an app?
