yes, unfortunately there is the same error with the NFC_fullExample, You provided.
Pressing READ, I need to touch the tag twice to read the data from it.
Removing triggers, then pressing READ, also needs to read twice. (its beeping for the 1st time also, but no data )
I have a NEXUS 5 phone.
Using the built in NFC reading app, my phone immediately showing, what is in the tag. The problem is only with the compiled apps.
I would be grateful if You could give me some hint, what am I doing wrong.
thanks in advance,
