Answer 1

File home = new File(MEDIA_PATH);

Then

walkdir(home);

WalkDir method

public void walkdir(File dir) {
String Pattern = ".mp3";
File listFile[] = dir.listFiles();
if (listFile != null) {
for (int i = 0; i < listFile.length; i++) {
if (listFile[i].isDirectory()) {
walkdir(listFile[i]);
} else {
if (listFile[i].getName().endsWith(Pattern)){

}
}
}  
}  
}
