I am trying to execute
adb shell am start -W -a android.nfc.action.NDEF_DISCOVERED -d "https://www.google.de"
in a way that would be similar to an actual NFC-Tag scan which has some URI (SmartPoster).
This is necessary, as the above command works e.g. with Chrome but not as a deeplink into a Capacitor app.
As far as I've discovered, it is necessary to send some extra data to this intent in order for this to work correctly as a deeplink for my use case.
However, I'm not really an android-dev and the docs are lacking examples regarding the correct syntax and contents of these extras.
According to https://developer.android.com/studio/command-line/adb#IntentSpec
These are the possible extra options to set:
-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE>
--esn <EXTRA_KEY>
--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE>
--ei <EXTRA_KEY> <EXTRA_INT_VALUE>
--el <EXTRA_KEY> <EXTRA_LONG_VALUE>
--ef <EXTRA_KEY> <EXTRA_FLOAT_VALUE>
--eu <EXTRA_KEY> <EXTRA_URI_VALUE>
--ecn <EXTRA_KEY> <EXTRA_COMPONENT_NAME_VALUE>]
--eia <EXTRA_KEY> <EXTRA_INT_VALUE>[,<EXTRA_INT_VALUE...]
--ela <EXTRA_KEY> <EXTRA_LONG_VALUE>[,<EXTRA_LONG_VALUE...]
--efa <EXTRA_KEY> <EXTRA_FLOAT_VALUE>[,<EXTRA_FLOAT_VALUE...]
(copied from: https://stackoverflow.com/a/26517290)
And there seems to be a new option for string arrays:
[--esa <EXTRA_KEY> <EXTRA_STRING_VALUE>[,<EXTRA_STRING_VALUE...]]
(to embed a comma into a string escape it using "\,")
(copied from https://stackoverflow.com/a/28638589)
According to google, the EXTRA_TAG ist passed as the extra for the intent.
When a tag is discovered, a Tag object is created and passed to a single activity via the NfcAdapter#EXTRA_TAG extra in an android.content.Intent via android.content.Context#startActivity.
Mandatory extra containing the Tag that was discovered for the ACTION_NDEF_DISCOVERED, ACTION_TECH_DISCOVERED, and ACTION_TAG_DISCOVERED intents.
The value of EXTRA_TAG is android.nfc.extra.TAG - see here
So my best guess currently is that something like this might work:
adb shell am start -W -a android.nfc.action.NDEF_DISCOVERED -d "https://www.google.de" --es android.nfc.extra.Tag 'flattened object?!'
Question: Does anybody know how to execute this correctly?
Thank you very much for your help!
