    The Intentones you use so far are Intentto open a specific activity. What you need to open the gallery is a Intentto request an action class, in this case ACTION_VIEW. Of course you will have to declare what type of element you want to display:

    Intent i = new Intent(); // nuevo Intent  
i.setAction(android.content.Intent.ACTION_VIEW); // clase de acción  
i.setType("image/*"); // a que tipo de datos queremos aplicar la acción?
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // queremos un task nuevo
startActivity(i); // ¡y dale!

    The type refers to the mime type of the content, so if you want to open the default gallery for videos, use "video/*"instead of image.

  2. There are several ways, for example:

    a)

    Intent intent = new Intent().setAction(Intent.ACTION_VIEW); //Define Intent.
intent.setType("image/*"); //Define mime type para abrir imagenes
startActivity(intent); //Abre galería.

    b) You can also do this by accessing the images directory:

    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("content://media/internal/images/media"));
startActivity(intent); //Abre galería.

    c) and this form using Intent.createChooser():

    private static int PICK_IMAGE = 1;
...
...
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, ""), PICK_IMAGE);
