Any file share via Bluetooth android app in android studio
First add below permissions in AndroidManifest.xml
[1] "android.permission.WRITE_EXTERNAL_STORAGE"
[2] "android.permission.READ_EXTERNAL_STORAGE"
[3] "android.permission.BLUETOOTH"
[4] "android.permission.BLUETOOTH_ADMIN"
After that you need only 3 file for that project.
one MainActivity.java and two xml files (activity_main.xml and dailoglayout.xml).
That's it.
Enjoy.... :) Happy coding and do cool things.
