오류 : 불행히도 앱이 중지되었습니다.

-2

Android를 배우고 Wingnity의 가이드를 따릅니다. Android Studio 2.1.3을 사용하고 있습니다.오류 : 불행히도 앱이 중지되었습니다.

2 개의 Java 클래스 (MainActivity 및 SimpleFragmentActivity)와 3 개의 레이아웃 (activity_main, activity_simple_fragment 및 fragment simple (empty))이 있습니다.

내 코드에 어떤 문제가 있는지 잘 모르겠습니다. 솔루션을 검색하려고 시도했지만 코드가 올바른 것으로 보입니다.

MainActivity

package com.example.ramosva.sunshine; 

import android.app.Fragment; 
import android.content.Intent; 
import android.support.v4.app.FragmentActivity; 
import android.support.v7.app.ActionBar; 
import android.support.v7.app.ActionBarActivity; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.view.ViewGroup; 
import android.support.v4.app.DialogFragment; 
import android.widget.Adapter; 
import android.widget.AdapterView; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 

import java.lang.reflect.Array; 
import java.util.ArrayList; 
import java.util.List; 
import java.lang.Object; 
import java.util.Arrays; 


public class MainActivity extends AppCompatActivity { 

    ListView listView; 

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



    } 

    public void simples(View v){ 

       Intent intent = new Intent(getApplicationContext(), SimpleFragmentActivity.class); 
       startActivity(intent); 
//  startService(intent); 

    } 

}

SimpleFragmentActivity

package com.example.ramosva.sunshine; 


import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v7.app.AppCompatActivity; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.Button; 
import android.widget.Toast; 


/** 
* A simple {@link Fragment} subclass. 
*/ 
public class SimpleFragmentActivity extends AppCompatActivity { 


    public SimpleFragmentActivity() { 
     // Required empty public constructor 
    } 

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

     if(savedInstanceState == null){ 
      getSupportFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment()).commit(); 
     } 
    } 

    public static class PlaceholderFragment extends Fragment{ 

     public PlaceholderFragment(){ 

     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
           Bundle savedInstanceState) { 
      // Inflate the layout for this fragment 
      View rootview = inflater.inflate(R.layout.activity_simple_fragment, container, false); 

      Button btnClickMeGym = (Button)rootview.findViewById(R.id.btnSimpleFragGym); 
      btnClickMeGym.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 

        Toast.makeText(getActivity(), "You clicked me Gym", Toast.LENGTH_SHORT).show(); 
       } 
      }); 
      return rootview; 
     } 

    } 

}

아무도 여기에 실수를 지적하시기 바랍니다 수 있습니다. 방금 Wingnity Tutorial 1 : Fragments 작성에 사용 된 코드를 따랐습니다.
