You need to put your list of pages in the Intent, which you run the second activation using the Intent#putStringArrayListExtra(String key, ArrayList<String> list) . Then, in the second activation, you need to remove this list from the Internet using the key.

In the first activity:

 ArrayList<String> ar = new ArrayList<String>(); ar.add("Apple"); ar.add("Banana"); Intent i = new Intent(this, SecondActivityClassName.class); i.putStringArrayListExtra("list", ar); startActivity(i);

In the second:

 ArrayList<String> ar1 = getIntent().getExtras().getStringArrayList("list");
