Am unable to get the Data from bundle in my application

In my app, i need to send a Two dimensional Array and two more integer values form on Activity to Another with the help of Intent method. This is done as ..

     Intent i = new Intent(getApplicationContext(), ViewActivity.class);
            Bundle postbundle = new Bundle();
            String[][] X={{"abc"},{"def"}};
            postbundle.putSerializable("data", X);
            i.putExtra("A", postbundle);

            i.putExtra("albumid", position);
            i.putExtra("Bigcard",bigcard);

here am using .putSerializable method to place an array into bundle.

So to access these data in the receiver Activity am using 

     Bundle bundle = getIntent().getBundleExtra("A");       
    String[][] ABC=(String[][]) bundle.getSerializable("data");
    Log.e("Array is",""+ABC);

but I got java.lang.NullPointerException error message..

Whith out use of " Static " declaration how can i get these values from bundle here (in the receiver Activity..)

Let me out pls from this ..

step-1:Write a seperate bean class and save into another file

public class MyBean implements Serializable{
String[][] data = null;
public void set2DArray(String[][] data){
    this.data = data;
}
public String[][] get2DArray(){
    return data;
 }
}

step-2:In the calling activity

        Intent intent = new Intent(this, Second.class);

   String data[][] = new String[][] {{"1","kumar"},{"2","sona"},{"3","kora"},{"1","pavan"},{"2","kumar"},{"3","kora333"}};
    MyBean bean = new MyBean();
    bean.set2DArray(data);
    Bundle b = new Bundle();
    b.putSerializable("mybean", bean);
    intent.putExtra("obj", b);
    startActivity(intent);

step-3:In the caller activity

        Bundle b = getIntent().getBundleExtra("obj");
       MyBean dData = (MyBean) b.getSerializable("mybean");
       String[][] str =dData.get2DArray();

Not a real answer, but a try:

what happens if You try:

    Intent intent = getIntent();
    int a = intent.getIntExtra("albumid"); //if Your value is an int, otherwise use String
                                           //getStringExtra or whatever Your value is
