Just add a file named .nomedia in the directory you want to exclude from MediaScanner.

Just Simple apply your own logic. when u read the file from internet is byte format. and after right in to sdcard.

this time just change the some byte of read file.and store this byte in some place like a sharepreference,Static varibale anything.and when you read file and display else play then change the same byte agian and replace this byte with orignal.this call incrypt and decrept. it`s work dear i do for image file.

Using the Internal Storage You can save files directly on the device's internal storage. By default, files saved to the internal storage are private to your application and other applications cannot access them (nor can the user). When the user uninstalls your application, these files are removed.

Android would automatically scan all folders on external storage for media files. If you don't want your image files to show in the gallery, maybe you could add some extension like ".myapp", this way cheats the scanner.

Another alternative is to save your image in a Database as a BLOB.
With this you are 100% sure that only your application can access it.
