I am a beginner with NFC's. I am using a Nexus % android phone to set up an audio trail in a museum. I have recorded something my voice using an app called Hi-Q MP3. I want to use tag to prompt a play back of the recording. I am using Tagwriter. When I go into My Datasets I can see the content and it asks me to tap an NFC. When I do this the audio app takes over but does not play the recording. What can I do to move on from this?
