try this
AssetManager mngr = getAssets();
InputStream path = mngr.open("music/music1.mp3");
BufferedInputStream bis = new BufferedInputStream(path,1024);
//get the bytes one by one
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
}
byte[] bitmapdata = baf.toByteArray();
After converting into byte array copy this into the sdcard as follows
File file = new File(Environment.getExternalStorageDirectory(), music1.mp3);
FileOutputStream fos;
try {
fos = new FileOutputStream(file);
fos.write(bitmapdata );
fos.flush();
fos.close();
} catch (FileNotFoundException e) {
// handle exception
} catch (IOException e) {
// handle exception
}
