是否可以在第一次执行时以编程方式更改应用程序名称和图标？

public class SettingsPage extends Activity{
    EditText edname,ednumber;
    Sharedprefference shpreff;
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.settingspage);
        shpreff = new Sharedprefference(getApplicationContext());
        edname=(EditText) findViewById(R.id.editname);
        ednumber=(EditText) findViewById(R.id.editnumbr);

        lname=edname.getText().toString();
        lnumber=ednumber.getText().toString();
        shpreff.setName(lname);
        shpreff.setPhonenumber(lnumber);
        shpreff.setCheck("true");
        shpreff.setChStat("true");
    }
public class SettingsPage extends Activity{
