Use this code to save an image Bitmap in android device gallery

public void savePhoto(Bitmap bmp)
{
imageFileFolder = new File(Environment.getExternalStorageDirectory(),"Rotate");
imageFileFolder.mkdir();
FileOutputStream out = null;
Calendar c = Calendar.getInstance();
String date = fromInt(c.get(Calendar.MONTH))
            + fromInt(c.get(Calendar.DAY_OF_MONTH))
            + fromInt(c.get(Calendar.YEAR))
            + fromInt(c.get(Calendar.HOUR_OF_DAY))
            + fromInt(c.get(Calendar.MINUTE))
            + fromInt(c.get(Calendar.SECOND));
imageFileName = new File(imageFileFolder, date.toString() + ".jpg");
try
{
 out = new FileOutputStream(imageFileName);
 bmp.compress(Bitmap.CompressFormat.JPEG, 100, out);
 out.flush();
 out.close();
 scanPhoto(imageFileName.toString());
 out = null;
} catch (Exception e)
{
e.printStackTrace();
}
}


public String fromInt(int val)
{
return String.valueOf(val);
}


public void scanPhoto(final String imageFileName)
{
msConn = new MediaScannerConnection(PreviewDemo1.this,new MediaScannerConnectionClient()
{
public void onMediaScannerConnected()
{
msConn.scanFile(imageFileName, null);
Log.i("msClient obj  in Photo Utility","connection established");
}
public void onScanCompleted(String path, Uri uri)
{
msConn.disconnect();
Log.i("msClient obj in Photo Utility","scan completed");
}
});
msConn.connect();
} 

Here i am saving the image in " Rotate " folder if you dont want that you can change it easily in savePhoto method.
