android activity class constructor working

Question

When considering the case with android activity, the first method to work is its onCreate method..right?

Suppose i want to pass 2 parameters to android

Answer 1

But you also can create very well a constructor of UserHome.

public class MainActivity extends Activity {
UserHome userHome = new UserHome(param1,param2);

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
userHome.yourMethod();
}}

Why do you think that is not possible to initialize a contructor?..MainActivity is a class like any other, just that extends Activity, but also keeps the properties of a class, so that can have, constructors, methods, members.
