How could I create a file in the "Internal Storage" Directory?

I have a Samsung Galaxy S6. I'm currently working on a test application where I would like quick access to a folder with my files.

Using the provided "My Files" Application, it specifies that all those folders are in the "Internal Storage" folder.

I know that internal storage is private, but I want to create a folder in the default folder that windows accesses when the phone is plugged in. For example, the following code does not create the directory in the correct location.

File storage = new File("/testappplication");
if(!storage.exists()) {
   storage.mkdir();
   System.out.println("Folder Created");
}

I just want to know the path where to create the folder. Many other applications have storage here, so I know its possible.

After a while later I found the answer to this question.

public void createDirectory() {
    File file = new File(Environment.getExternalStorageDirectory(), "/test");
    if (!file.exists()) {
        file.mkdirs();
        Log.w("DEBUG", "Created default directory.");

    }
}

This is how you create it code wise. The reason it wasn't creating was due to Samsungs weird permissions.

Make sure you have the storage permission enabled in Settings -> Apps -> App Name -> Permissions. I needed to turn it on so it would create the folder.

First just for trial make runtime permmision and then try the following code 

 private void createInternalFile() {
    File mediaStorageDir = new File(Environment.getExternalStorageDirectory()+"/"+getApplicationContext()
            .getPackageName()+"/File/profile");
    if (!mediaStorageDir.exists()) {
        mediaStorageDir.mkdirs();
    } }

then check your internal storage in which you will find a folder whose name is your package name

You can't create a directory inside the internal storage of the device. Except you've a root access for the app.

So, the following code won't work:

File storage = new File("/testappplication");

Because it tell the app to create a testappplication in the root folder.

You can only create the directory inside your app private folder within the following path:

String path = getFilesDir().getAbsolutePath();

And make the folder using the path.

Or you can use something like this:

File folder = new File(context.getFilesDir(), "testappplication");
if (!folder.exists()) {
    folder.mkdirs();
} else {
  // folder is exist.
}
