Are activities created by intents of the same class, the same activity?

If I create a new Intent of the same class every time I click a button, is the created activity the same?

Every time I click a button, I want to have a dialog show with a slider inside it and after I change it I want the state to be saved so that the next time I open up the dialog the state of the slider is the same.

My code for the button is this:

button.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        Intent intent = new Intent(v.getContext(), Slider_Logic.class);
        v.getContext().startActivity(intent);               
    }
});

By "same," I assume you mean the same object instance. The answer is no. In general, when you start a new activity, it creates a new instance of that activity and pushes it onto the stack in front of the existing activity.

I say "in general" because the activity's launch mode can effect this behavior. For example, if you set launchMode to singleTop, it will create a new instance of the activity if one doesn't already exist in the target task. Please see the docs for more information.
