Hello

Iím really new in java programming. Iím trying to build an android application that will be enabled by NFC, record sound (during sleep) continuously (in separated files of 1-2 minutes length and then start a new recording file), uploading each one of them (right after itís recorded) on a server and then deleting them from the phone. Also I want to add a UTC timestamp to every file , to be able to synchronize these sounds recordings with other signals, on the same graph.
Iíve found this (http://androidcodeexamples.blogspot....n-android.html) open source app, which records audio. I need to make it to :
1. Start while I put the phone on the NFC
2. Record files with 1-2 minutes max length
3. Upload each one on the server and then delete it from the phone
4. Add UTC timestamps
Could you help me with any of these? Any Help would be appreciated.
Thanks in advance!
