How to save uploaded file to sdcard folder , currently it stores to /data/data/cache folder with filename like "NanoHTTPD-some random number".
I am not able to copy it to any folder location in sdcard.
I would like to save the file to a pre-mentioned folder location in sdcard with the same name as the original file name was uploaded from my html page.
I have tried all sort of codes .But file copy fails all the time. 1)Not able to get correct location of temp file. 2)Not getting original filename that the form was posted with
Here is my implementation .
Please help i am stuck.
