I’m working on a File Sharing application in Android. I came to see an app name InShare (Link: text), this application is very simple working and easy to use. The thing I don’t understand about this application is how does it works.
This application doesn’t create a hotspot and connect the second device to it and use socket to share files between them.
On the receiver side InShare will simply show a QR code to scan. It also shows the below details after the QR Code:
Hotspot: DIRECT-tl-88******
Password: RBS*****
The QR Code also contains the same details in it. But this is not a hotspot created on that device. When you scan the QR Code from the Sender device it will create a connection between these devices and share files between them. But the sender device is not connected to any Hotspot. This sharing will work even both devices are not connected to any kind of wifi.
