Solution 1:

On your phone go to

Settings->Storage

and verify if the flag for Mass storage only isn't selected. When it is selected, your Device can't access the SD card for debugging purposes (nor other purposes in general). That's quite likely the reason the creation of your file is failing.

The file you are using to seed your DB is not found, it must be on your filesystem on your machine (emulator can find it).
