For Activity 1:

 ArrayList<String> Customers = new ArrayList<String>();
 Intent i=new Intent(Activity1 .this,Activity2.class);
 i.putStringArrayListExtra("customers1",(ArrayList<String>) Customers);         
 startActivity(i);

For Activity 2:

 ArrayList<String> Customers = new ArrayList<String>();
 Bundle extra=getIntent().getExtras();
    if(extra!=null){
        Customers =extra.getStringArrayList("customers1");  
    }

If you create a public static variable, you can access it in a static way:

In Activity2.class:

Activity1.customers;

when the arraylist is public static, you can directly access it using classname.arraylist na.

Activity1.cutomers
