try {
    File cashDir = new File(dir.getCanonicalPath(),"folder");
    if(!(cashDir.exists())) cashDir.mkdirs();
} catch (IOException e) {
    e.printStackTrace();

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

File direct = new File(Environment.getExternalStorageDirectory()+"/folder_name");

if(!direct.exists()) {
     if(direct.mkdir()); //directory is created;
}

To create directory on phone primary storage memory (generally internal memory) you should use following code. Please note that ExternalStorage in Environment.getExternalStorageDirectory() does not necessarily refers to sdcard, it returns phone primary storage memory

File mediaStorageDir = new File(Environment.getExternalStorageDirectory(), "MyDirName");

if (!mediaStorageDir.exists()) {
    if (!mediaStorageDir.mkdirs()) {
        Log.d("App", "failed to create directory");
        return null;
    }
}

Directory created using this code will be visible to phone user. The other method (as in accepted answer) creates directory in location (/data/data/package.name/app_MyDirName), hence normal phone user will not be able to access it easily and so you should not use it to store video/photo etc.

You will need permissions, in AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />

There is a "cacheDirectory" in your "data/package_name" directory.

If you want to store something in that cache memory,

File cacheDir = new File(this.getCacheDir(), "temp");
if (!cacheDir.exists())
    cacheDir.mkdir();

where this is context.

Here is the code which I am using for creating files in internal memory :

    File myDir = context.getFilesDir();
    // Documents Path
    String documents = "documents/data";
    File documentsFolder = new File(myDir, documents);
    documentsFolder.mkdirs(); // this line creates data folder at documents directory

    String publicC = "documents/public/api." + server;
    File publicFolder = new File(myDir, publicC);
    publicFolder.mkdirs(); // and this line creates public/api.myservername folder in internal memory
