You can pass data like this(this is from SecondActivity):

Intent intent = new Intent(this, ThirdActivity.class);
intent.putExtra("EXTRA_SESSION_ID", sessionId);
startActivity(intent);

and than in ThirdActivity in onCreate method:

String sessionId = getIntent().getStringExtra("EXTRA_SESSION_ID");

Also, best practise is to have key "EXTRA_SESSION_ID" stored in public static variable so you have only one object

1.Change this to arraylist

 String[] mackor_names = {
            "Tonfisk Macka 30:-",
            "Skagen Macka 35:-",
            "Kyckling Macka 35:-",
            "Curryröra Macka 30:-",
            "Ost o Kalkon Macka 25:-",
            "Köttbulle Macka 25:-",
            "Falafel Macka 20:-"
        };






  ArrayList<String> list = new ArrayList<>();
    list.add("Tonfisk Macka 30:-");
    list.add("Skagen Macka 35:-"); ......

2.and then use

intent.putStringArrayListExtra("test",list);

3.and to get values

Intent intent=getIntent();
ArrayList<String> test = intent.getStringArrayListExtra("test");

Solution 3:[3]

//Create the bundle
Bundle bundle = new Bundle();
//Add your data from getFactualResults method to bundle
bundle.putString("VENUE_NAME", venueName);  
//Add the bundle to the intent
i.putExtras(bundle);

Insead of array you can use bundle
