Android device or resource busy - honeycomb

On the 3.0 honeycomb, I a开发者_开发技巧m getting this error when trying to access a file. It does not happen all the time. What causes is that I browse around the market a bit and then I come back to my app. It tries to access a file, and i get this error:

To get the same code working again after I restart the device, i.e. power off/on.

The same code works fine on the android version 7, but at times it crashes on v11.

I had the same issue that came out of nowhere: embedded sdcard answered with "Device or resource busy". Tried pretty much everything. Cold reboot was the only thing that helped.

It was a file system lock in my case, unplugging and re-plugging the usb cable helped me.

I figured the issue was with the folder not the file. So as a work around, I just create a new tmp folder within my app folder and try to save the file.
