I want to write a NFC tag that opens a specific note in Google Keep when touched.
I have an URL in the form of https://keep.google.com/u/0/#LIST/<id> that does the desired action of opening the note in the installed Google Keep app on my phone when I read it with a QR-reader or click on it as a link.
When I write this URL to the tag an touch the tag afterwards, it opens in the browser. Is the NFC handler skipping other apps and opening it directly in a browser? When I clear the app-defaults for the browser, it shows a selection menu for the installed browsers after tapping the tag. Does anyone have an idea what I am doing wrong?
Links on NFC tags are not launched as intents with the typical VIEW action. Consequently, other apps may not pick those links up correctly and you will instead experience the web browser to be opened. Only apps that specifically register for the intent action NDEF_DISCOVERED will be able to receive links from NFC tags. It seems that Google Keep currently does not do this, so there's not much you can do without creating your own wrapper app that handles these URLs and passes them on to Google Keep.
