Question

I am trying to replace the toasts in the code below with intents, but no matter how many methods i try they fail to work. The issue is nothing but a white screen on the emulator when loading up the application.
Any assistance would be appreciated.

    spinner.setOnItemSelectedListener(new OnItemSelectedListener()
    {

        public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            // TODO Auto-generated method stub
            switch (arg2) {
            case 0:                 
                Toast.makeText(UsefulToolsActivity.this, "Tool, Countdown. Selected.", Toast.LENGTH_SHORT).show();
                break;

            case 1:                 
                Toast.makeText(UsefulToolsActivity.this, "Tool, Countdown. Selected.", Toast.LENGTH_SHORT).show();                       
                break;

            default :                       
                break;
            }
        }

        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
        }
    });
}

Here is the code i tried using to implement the intents

    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            // TODO Auto-generated method stub
            switch (arg2) {
            case 0:                 
                Intent intent1 = new Intent(UsefulToolsActivity.this, CountdownActivity.class);
                startActivity(intent1);                        
                break;

            case 1:                 
                Intent intent2 = new Intent(UsefulToolsActivity.this, CountdownActivity.class);
                startActivity(intent2);                       
                break;

            default :                       
                break;
            }
        }

        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
        }
