Question

I am using this method to return a result code and then get a contacts information from the contacts database.

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

     switch (requestCode) {
        case (CONTACT_PICKER_RESULT) :
          if (resultCode == Activity.RESULT_OK) {
              Uri contactData = data.getData();
              Cursor cursor =  managedQuery(contactData, null, null, null, null);
              while (cursor.moveToNext()) 
                {           
                    String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
                   name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)); 

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

if ( hasPhone.equalsIgnoreCase("1"))
                        hasPhone = "true";
                    else
                        hasPhone = "false" ;

if (Boolean.parseBoolean(hasPhone)) 
                    {
                     Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
                     while (phones.moveToNext()) 
                     {
                      phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                     }
                     phones.close();
                    }

                    break;

            }
            ContactInfo.setText("Contact: " + name + "./n" + " Phone Number: "+ phoneNumber);
             }
          }

     }

The problem is i keep getting this error.

Answer 1

I think your problem is located in some of that cursor.getColumnIndex , maybe ContactsContract.Contacts._ID is the problem ones .
But my tip for you is debug one by one putting a watch on all ContactsContract.* access you have in that code .

The ones who returns a -1 is the one who is giving you the problems.
