UsbMassStorageDevice[] devices = UsbMassStorageDevice.getMassStorageDevices(this / Context or Activity /);
for(UsbMassStorageDevice device: devices) {
}
app crashes with this code am using it in on create method of activity
and how do i get permisson to read and what is broadcast reciever doing on start
please give me simple code to list files with all the permission
because ur example activity contains lots of other code which i dont need
