Creating JPEG File In Internal Storage

I am writing a code for an android app in which I have to captures image and save it into internal storage of android. For this I have written the following code-

Code:

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
String newPath = PATH+"/"+folderName+"/"+imageName+".jpg";
File file = new File( newPath );
file.mkdirs();

[Code]...

This code creates jpeg file but don't write the image into it.

Later I tried writing following code in onActivityResult-

Code:

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0, bos);
byte[] bitmapdata = bos.toByteArray();

[Code]...

But its still not working.
