Creating Directories on the SD Card

I am posting this code (from Kur1310) on how to create directories on the SD Card as it might not be immediately obvious.

Info: value = the folder you are trying to create. (Example: Folder, or Folder/Subfolder)

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
String sdCard = "/sdcard" , value = "";
 
String[] command = { "mkdir",sdCard+"/"+value};
 
try {
 
Process process = Runtime.getRuntime().exec(command);
 
}catch (IOException e) {
 
Toast.makeText(this, ""+e, Toast.LENGTH_LONG).show();
 
}

Another way, all in Java:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

try {
 
        File path = new File("/sdcard/foo/bar");
 
        if(! path.isDirectory()) {
 
                path.mkdirs();
 
        }
 
} catch(IOException e) {
 
        // ...
 
}

Some more recommendations on file paths and the SD card:

Don't hardcode the path "/sdcard". Instead, use Environment.getExternalStorageDirectory()
Don't hardcode "/" characters in your paths. For maximum compatibility of your code on non-Android platforms, use File.separator.
Instead of concatenating strings and separators to make paths, the cleanest method is to build File objects using the different constructors available like File(String dirPath, String name) or File(Uri uri).
