I am having problem, while trying to copy audio files from raw folder to SD Card, I have successfully created folder in SD Card, but not able to copy songs in that...
I am using this tutorial: http://www.androidhive.info/2012/03/android-building-audio-player-tutorial/
String path = Environment.getExternalStorageDirectory() + "/PriyankaChopra" ;
File dir = new File(path);
try{
if(dir.mkdir()) {
final int[] mSongs = new int[] { R.raw.exotic, R.raw.pyaar, R.raw.tinka };
for (int i = 0; i < mSongs.length; i++) {
try {
String str_song_name= i +".mp3";
CopyRAWtoSDCard(mSongs[i], "/sdcard/PriyankaChopra/"+str_song_name);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
} else {
System.out.println("Error, while Copying songs to SD Card!");
}
}catch(Exception e){
e.printStackTrace();
}
}
private void CopyRAWtoSDCard(int id, String path) throws IOException {
InputStream in = getResources().openRawResource(id);
FileOutputStream out = new FileOutputStream(path);
byte[] buff = new byte[1024];
int read = 0;
try {
while ((read = in.read(buff)) > 0) {
out.write(buff, 0, read);
}
} finally {
in.close();
out.close();
}

Replace your code with mine.
it is working perfect here.
Add only this Permission :
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Java Code :
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
public class Sample extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final int[] mSongs = new int[] { R.raw.background, R.raw.background1, R.raw.background2 };
for (int i = 0; i < mSongs.length; i++) {
try {
String path = Environment.getExternalStorageDirectory() + "/PriyankaChopra";
File dir = new File(path);
if (dir.mkdirs() || dir.isDirectory()) {
String str_song_name = i + ".mp3";
CopyRAWtoSDCard(mSongs[i], path + File.separator + str_song_name);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
private void CopyRAWtoSDCard(int id, String path) throws IOException {
InputStream in = getResources().openRawResource(id);
FileOutputStream out = new FileOutputStream(path);
byte[] buff = new byte[1024];
int read = 0;
try {
while ((read = in.read(buff)) > 0) {
out.write(buff, 0, read);
}
} finally {
in.close();
out.close();
}
}
}
you forget to add song file name and extension with path on sdcard :
CopyRAWtoSDCard(mSongs[i], "/sdcard/PriyankaChopra/"); <<<<<
do it as :
String str_song_name="song_name_"+i+".mp3";
CopyRAWtoSDCard(mSongs[i], "/sdcard/PriyankaChopra/"+str_song_name);
and also use Environment.getExternalStorageDirectory() for getting sdcard path instead of static path
