This sample demonstrates how to transfer large files via Android Beam. After the initial handshake over NFC, file transfer will take place over a secondary high-speed communication channel such as Bluetooth or WiFi Direct.
This feature requires Android 4.1 (Jelly Bean) or above. Unlike traditional Beam, your application will not receive an Intent on the receiving device. Instead, the system will save the file to disk and display a notification that the user can select to open the file using a standard ACTION_VIEW Intent.
This sample uses the Gradle build system. To build this project, use the "gradlew build" command or use "Import Project" in Android Studio.
