Android device or resource busy - cellular

On honeycombs 3.0, I get this error when trying to access a file. This does not always happen. What are the reasons that I browse the market a bit and then return to my application. It tries to access the file, and I get this error:

To run the same code again after restarting the device, i.e. off / on.

The same code works fine on Android version 7, but sometimes it crashes on v11.

I had the same problem that came out of nowhere: the built-in SD card replied "Device or resource busy." I tried almost everything. A cold reboot was the only thing that helped.

I realized that the problem is with the folder, not the file. Therefore, when you work, I just create a new tmp folder in my application folder and try to save the file.
