Try to start an Activity with the intent that was created by the tag dispatch system when parsing the NFC tag (either ACTION_NDEF_DISCOVERED or ACTION_TECH_DISCOVERED).
If no activities filter for that intent, try to start an Activity with the next lowest priority intent (either ACTION_TECH_DISCOVERED or ACTION_TAG_DISCOVERED) until an application filters for the intent or until the tag dispatch system tries all possible intents.
If no applications filter for any of the intents, do nothing.
