crash on read
I installed your provided APK to my GNEX. I attached a NFC Card to the phone and the App suddently crashed after output of some text.
How can I provide more information about this issue?
The app doesn't do anything useful, I am surprised somebody is actually trying to run it. :-)
You can send the Android log output, containing the crash trace, but I doubt anybody would bother trying to fix it.
I have the same on Nexus7. How to obtain log output? Is possible to connect android device as USB RFID reader? https://android.googlesource.com/kernel/omap.git/+/30028a1f5f76a78244ac80dd670a58c3c9228470/drivers/misc/pn544.c - nexus 7?
You can use adb logcat to get log output (I am assuming you what adb is). But, again, the app is completely useless, don't waste your time trying to use it.
I don't think you can make your android device act as an USB RFID reader.
It crash only with a encrypted mifare classic card. It doesnt with an empty card
