한 Android's default external storage folders 사용을 고려 (현재 파일에서 sdcard에 직접 저장하는)이

File path = Environment.getExternalStoragePublicDirectory(
    Environment.DIRECTORY_MUSIC); 

당신이 사용할 수 있습니다 같은 DIRECTORY_MUSICFile class constructor을 사용하여 SD 카드에 새 폴더를 만드십시오.

File audioFolder = new File(Environment.getExternalStorageDirectory(), 
    "newaudiofolder") 
if (!audioFolder.exists()) { 
    boolean success = audioFolder.mkdir() 
    if (success) { 
     // save the file 
    } 
}
