You can call android.os.Environment.getExternalStorageDirectory() to
get the path to the external storage device. That will handle the case
where recommended external store is no the SD card but some other
device.
If there is no external storage, you can try saving to your app's
private data directory. Another alternative it to stream the media
from a server, but this obviously introduces the complexity and cost
of maintaining the service for your users.
All of the Android standard apps (camera, music, sound recorder) that
create or use media files assume that the device will have external
storage. In the end, you have to decide whether it's worth supporting
users that don't have external storage.
