onActivityResult() Does not get called?

I have an MainActivity which has two TextView. User has an option to start another activity and choose data from ListView to fill those TextView. My main activity has an OnClickListener which starts an Activty from which user can select data and come back to main activity.My OnClickListener code looks likes this:

private static final int PICK_START = 0;
private static final int PICK_END = 1;
@Override
    public void onClick(View v) {
        Log.i(MainActivity, "view clicked");
        int id = v.getId();

        if (id == R.id.searchR) {
                        //do nothing
        } else if (id == R.id.startSearch) {
            Intent startIntent = new Intent(this, SList.class);
            startActivityForResult(startIntent, PICK_START);

        } else if (id == R.id.endSearch) {
            Intent startIntent = new Intent(this, SList.class);
            startActivityForResult(startIntent, PICK_END);
        }

    }

When the above onClick method gets called and after that its starts another activity SList.class.In that I have a listview from which user can select the value and upon selecting value the result will be set and activity will finish itself.Code for this is:

sListview.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                Station selectedS = sArray.get(position);
                Intent returnIntent = new Intent();
                returnIntent.putExtra("_id", selectedS.getId());
                returnIntent.putExtra("name", selectedS.getName());
                setResult(RESULT_OK, returnIntent);
                finish();
            }
        });

In above code activity sets the result and finishes itself.Till here everything is working accordingly.But after that when the previous activity is started, the onActivityResult() method nevers gets called.The code for onActivityResult() is :

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        Log.i(MainActivity, "" + requestCode);

        // Make sure the request was successful
        if (resultCode == RESULT_OK) {
            // Check which request we're responding to
            if (requestCode == PICK_START) {
                //data.getStringExtra("_id");
                Log.i(MainActivity, data.getStringExtra("name"));

            } else if (requestCode == PICK_END) {
                Log.i(MainActivity, data.getStringExtra("name"));
            }
        }
    }

I dont know why onActivityResult is never triggered .Someone even wrote on his blog that There is bug in android API. In startActivityForResult(intent, requestCode); This function does work as long as requestCode = 0. However, if you change the request code to anything other than zero, the ApiDemos will fail (and onActivityResult() won't be called).
