Titanium Alloy App hangs or reverts to Splash Screen

Dear fellow Developers

New at Ti.Alloy ... new at JS ... teaching myself via tutorials and examples. New subject is NFC. I've built two apps that have both reverted or hung up at Splash Screen. I've searched most forums but no resolution yet. The most recent is the the example by Jeff English : https://github.com/appcelerator-modules/ti.nfc/tree/master/android/example/TagViewer that I'm working through. This app runs well but once a tag is read the app reverts almost immediately from the data display View to the Splash Screen and has to be re-launched.

Host PC on Windows 7 / Titanium SDK 3.2.3 / Titanium Studio 3.2.3.201404181442 / Device Android S4 Mini via USB.

Your help would be most appreciated .. I've had a very frustrating learning curve.
