But i want to create folder in Internal Storage.

    private static String contacts_storage_path;

    contacts_storage_path = Environment.getExternalStorageDirectory().toString()+"/"+folderName;
            contactsFile = new File(contacts_storage_path);
            if (!contactsFile.exists())
            {
                 //contactsFile.createNewFile();
                contactsFile.mkdirs();
            } 
             filecontact=new File(contactsFile, contact_file_name);

Answer 1

It is important to use Context.getDir(String value, int mode) to create directory in internal storage.

Refer below code -

File mydir = context.getDir("mydir", Context.MODE_PRIVATE); //Creating an internal dir;
File fileWithinMyDir = new File(mydir, "myfile"); //Getting a file within the dir.
FileOutputStream out = new FileOutputStream(fileWithinMyDir); //Use the stream as usual to write into the file.

You can create a folder in Internal memory like this:

File dir = context.getDir("dir", Context.MODE_PRIVATE);
dir.mkdirs();

Answer 3

FileOutputStream outStream = null;
**File sdCard = Environment.getExternalStorageDirectory();**
**File dir = new File(sdCard.getAbsolutePath() + "/YourFolderName");**
dir.mkdirs();
//to know the path
Log.d(TAG, dir.getAbsolutePath();
String fileName = String.format("%d.jpg", System.currentTimeMillis());
File outFile = new File(dir, fileName);
outStream = new FileOutputStream(outFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
outStream.flush();
outStream.close();

Hope this helps!
