copying Integer Array to next activity

Question

I have

Integer[] mainArray;

In one of my activity which was filled randomly with unique values.
Now I want this array to copied to next activity?
How can be achieved? I have seen that there seems to be no option to carry it with

Bundle b=new Bundle();
b.putIntArray("key", mainArray);
Intent i=new Intent(context, Class);
i.putExtras(b);

you have right code for sending Array to next Activity then what is issue ? yes u have one more operation by create a singleton class to share data between Application components — ρяσѕρєя K, Feb 04 '13 at 13:43
with above code, eclipse says :The method putIntArray(String, int[]) in the type Bundle is not applicable for the arguments (String, Integer[]) — Nandroid, Feb 05 '13 at 10:13

It is exactly what you need :

Bundle b=new Bundle();
b.putIntArray("key", mainArray);
Intent i=new Intent(context, Class);
i.putExtras(b);

Just get the data from it on your other activity,
on onCreate() :

int data[] = getIntent().getIntArrayExtra("key");

What is the problem?

There is a difference between int and Integer in Java. You can find out more about it here : What is the difference between an int and an Integer in Java and C#?

In the activity sending the integer array use:

intent.putExtra("array", mainArray);

In the activity receiving this integer array use:

int array[] = getIntent().getIntArrayExtra("array")

Try this,

Instead of integer array use arraylist.

Intent i=new Intent(context, Class);
 i.putIntegerArrayListExtra("name", arraylist);
 startActivity(i);

Other this integer arraylist to next activity

 Intent i = getIntent();
 ArrayList<String> list = new ArrayList<String>();
 list = i.getStringArrayListExtra("name");
