startChildActivity issue when working with TabGroupActivity

Question

Fallowing is Home class. I am going to call Pick_contact intent. When ContactNumber view is clicked, device contact list is shown. And the result of picked contact is getting on TabGroupActivity.

public class Home extends Activity{
    private static int PICK_CONTACT= 1;
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.home);
    }

public void ContactNumber(View v)
    {
       Intent intent = new  Intent(Intent.ACTION_PICK,ContactsContract.Contacts.CONTENT_URI);
       parentActivity = (TabGroupActivity)getParent();
       parentActivity.startActivityForResult(intent, PICK_CONTACT);
    }

}

My TabGroupActivity code is shown below.

public class TabGroupActivity extends ActivityGroup {

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

if(requestCode == PICK_CONTACT)
        {
             if (resultCode == Activity.RESULT_OK) {

                 Uri contactData = data.getData();
                 Cursor c =  managedQuery(contactData, null, null, null, null);
                 String cNumber="";
                 if (c.moveToFirst()) {


                     String id =c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

                     String hasPhone =c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

                       if (hasPhone.equalsIgnoreCase("1")) {
                      Cursor phones = getContentResolver().query( 
                                   ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
                                   ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id, 
                                   null, null);
                         phones.moveToFirst();
                          cNumber = phones.getString(phones.getColumnIndex("data1"));
                         System.out.println("number is:"+cNumber);
                       }
                     String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                    QRCodeStaticData.qr_contents=name;

                 }

               }
        }
}

}

In this above code when user pick up contact from list, I want to open other child activity. But if user does not pick up contact and just cancel it, user will leave on the home activity. I am not getting how to call child activity inside TabGroupActivity after picking contact. I used below code to call child activity.

Intent intent = new Intent(getParent(), CreateQRCode.class);
TabGroupActivity parentActivity = (TabGroupActivity) getParent();
parentActivity.startChildActivity("CreateQRCode", intent);

But it does not work inside onActivityResult of TabGroupActivity.

Try this...Sorry for the Late Answer

In your TabGroupActivity

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    tabHost = (TabHost) findViewById(android.R.id.tabhost);
    // Adding the Activities to the tab view
    // Blah Blah
}

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        System.out.println("Success");
        if (requestCode == PICK_CONTACT) {
            //Here you can launch the Child Activity according to the index
            //Here CreateQRCode Activity index is 1 in the TabView
            tabHost.setCurrentTab(1);
        }
    } else {
        System.out.println("Fail");
    }
}

In your HomeActivity

public void ContactNumber(View view) {
    Intent intent = new Intent(Intent.ACTION_PICK,
            ContactsContract.Contacts.CONTENT_URI);
    startActivityForResult(intent, PICK_CONTACT);
}
