This course introduces the new features offered to developers and consumers in Android 4.1 Jelly Bean. Author Joseph Lowery first explains how you can expect the update to roll out to devices, and then shows how to install the Android SDK on Windows and Mac, select a device emulator, create a sample app, and prep it for publication on Google Play. Along the way, the course explores the smoother interface (codenamed Project Butter), notifications, advanced text manipulation, and security improvements that will be of interest to Android developers, and describes how those features translate for consumers on the device side.
NFC, or Near Field Communication, is exactly what it sounds like, if you speak tech. When two devices are near each other, they can communicate. This feature was first introduced in Android 4.0 as Android Beam, and beefed up in Jelly Bean. Now you can easily send images, and even video, from one device to another. Beam now uses bluetooth to do the file transfer. You need to make sure that your bluetooth is on on both devices. You'll also want make sure the NFC is enabled, although it should be by default.
To transfer an image, you need to go to the Gallery. So I am going to Home, and then on my second page, Gallery, and there's my image. The next up is to hold the two devices back to back, and in a second, you will hear a vibration and see a message, Touch to beam. When you see that, tap the picture, you will get a confirmation tone from the device, and now, if you go to the Notifications on the tablet quick enough, you'll see an incoming Beam message, and once that finished, you'll see it says Beam complete, touch to view. So let's tap that, and there you have it.
Wireless transfer via the Android Beam.
