Android的Activity什麼時候會調用onCreate()而不調用onStart()？

Android的Activity什麼時候會調用onCreate()而不調用onStart()？這是一道面試題。目前網上有關資料不多，就只有一篇知乎文章：

說是在onCreate裏面添加ondestroy，本人試了是不行的。廢話不多說，直接貼代碼：

package com.example.dispatchevent;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnTouchListener;
import android.widget.Button;

public class MainActivity extends Activity {
	Button btn;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		Log.d("TAG", "onCreate");
//		super.onStop();
//		super.onDestroy();
		finish();
		btn = (Button)findViewById(R.id.btn1);		
	}
	@Override
	protected void onDestroy() {
		// TODO Auto-generated method stub
		super.onDestroy();
		Log.d("TAG", "onDestroy");
	}
	@Override
	protected void onPause() {
		// TODO Auto-generated method stub
		super.onPause();
		Log.d("TAG", "onPause");
	}
	@Override
	protected void onRestart() {
		// TODO Auto-generated method stub
		super.onRestart();
		Log.d("TAG", "onRestart");
	}
	@Override
	protected void onResume() {
		// TODO Auto-generated method stub
		super.onResume();
		Log.d("TAG", "onResume");
	}
	@Override
	protected void onStart() {
		// TODO Auto-generated method stub
		super.onStart();
		Log.d("TAG", "onStart");
	}
	@Override
	protected void onStop() {
		// TODO Auto-generated method stub
		super.onStop();
		Log.d("TAG", "onStop");
	}
}

我們在onCreate()裏面加了super.onStop();或super.onDestroy();，這樣執行到onCreate()函數時，執行流程是這樣的：onCreate -> onStop或onDestroy -> onStart -> onResume。最終還是會執行onStart。而如果加上finish()，則onCreate -> onDestroy，而不會執行onStart。
