Literally, I think the only answer is:
Runtime.getRuntime().exec("chmod 755 " + fileName);
If you create files via openFileOutput(), you can specify permission
bits, but that only works for files immediately in the app-local file
store.
Or, put the files on the SD card.
Or, create a content provider that serves up the files to the
MediaPlayer. This is probably the best answer (does not assume
command-line binaries that may or may not exist).
