It is not necessary that an Activity must have a layout file. You can have a condition check in your launcher activity and redirect to other activity based on the condition. (The transition from launcher activity to condition activity will not be visible though).

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent;
if (condition) {
   intent = new Intent(this, FirstClass.class);
} else {
   intent = new Intent(this, SecondClass.class);
}
startActivity(intent);
finish();
// note we never called setContentView()
}

Other Activity (FirstClass / SecondClass ):

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