Set the imageView src based on the value selected in a Spinner

I've been trying to set an ImageView (Default empty) based on the value selected from a Spinner. So in the mainActivity.java 

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    sp_home = (Spinner) findViewById(R.id.spinner_home_team);
    sp_away = (Spinner) findViewById(R.id.spinner_away_team);


    sp_home.setOnItemSelectedListener(new OnItemSelectedListener() {
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                                   int arg2, long arg3) {
            if (!sp_home.getSelectedItem().toString().equals("Seleziona Squadra")) {
                setTeamLogo(sp_home.getSelectedItem().toString(), "home");
            }
        }

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

    sp_away.setOnItemSelectedListener(new OnItemSelectedListener() {
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                                   int arg2, long arg3) {
            if (!sp_away.getSelectedItem().toString().equals("Seleziona Squadra")) {
                setTeamLogo(sp_away.getSelectedItem().toString(), "away");
            }
        }

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

}

The setOnItemSelectedListener method works perfectly the problem comes when I execute the code inside setTeamLogo.

private void setTeamLogo(String teamName, String home_or_away_team){

    int resId = getResources().getIdentifier(teamName, "drawable", getPackageName());
    Toast.makeText(getBaseContext(), resId,
            Toast.LENGTH_LONG).show();


}

The exception that has been thrown is: android.content.res.Resources$NotFoundException: String resource ID #0x0

Any idea why if I use the name of the image instead of the variable teamName everything works perfectly?

Use String.valueOf()

If you pass it an integer it will try to look for the corresponding string resource id - which it can't find, which is your error.
