Hi andrew, As you can see this code checks for Writable and Size limitations. I tried to write a Contact info. At this time I got Size limitation error.
Anyways i think by tag is writable and also has sufficient size. Just that I am not able to figure out why that error is occuring.. Also after this error, I deliberately tried to "Format" and write the ndef message. I got "Tag doesn't support NDEF." error. But this is not possible since ndef!=null code was executed previously. I am not sure why this is happening. Please advice.
