Make a path for create a file in Java (Android)

Question

Given a File object how can I create the path for saving it?

I tried file.mkdirs() but for example if the file's path is:

/mnt/sdcard/downloads/myapp/temp/song.mp3

it also creates a folder named "song.mp3" inside temp.

How can I do it correctly?

use this code

File myDir=new File("/sdcard/Download");
myDir.mkdirs();
String fname = "Image.jpg";
File file = new File (myDir,fname);

Just try:

file.getParentFile().mkdirs();

this will create the parent directory.

File.getParent()

If you just want to extract the path you can use lastIndexOf:

String p = "/mnt/sdcard/downloads/myapp/temp/song.mp3";
System.out.println(p.substring(0,p.lastIndexOf('/')));

Of course, if you already have File object then getParent(), as suggested, will be easier.
