view안에 onDraw로 사각형을 넣을려고합니다.

Question

?

package com.example.dodgegame;   import com.example.dodgegame.Gameplayer.MyView;   import android.content.Context; import android.content.pm.ActivityInfo; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.os.Bundle; import android.os.Handler; import android.support.v7.app.ActionBarActivity; import android.view.KeyEvent; import android.view.View; import android.view.Window; import android.view.WindowManager; import android.view.View.OnKeyListener; import android.widget.RelativeLayout; import android.widget.TextView;       public class Gamecanvas extends ActionBarActivity {           private int minute = 0;     private int second = 0;     private TextView text;     private TextView mCountDown;     private TextView t;     private int count = 0;           private Handler handler = new Handler();//초기화           @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         requestWindowFeature(Window.FEATURE_NO_TITLE);           getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,                                              WindowManager.LayoutParams.FLAG_FULLSCREEN);         setContentView(R.layout.gamecanvas);         setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);                   handler.removeCallbacks(doUpdateTimer);         handler.postDelayed(doUpdateTimer, 1000);                   mCountDown = (TextView)findViewById(R.id.textview02);         mCountDown.setText(String.valueOf(count));         autoCountHandler.postDelayed(autoCountRunnable, 1000);         }       private Runnable doUpdateTimer = new Runnable() {         public void run() {                           second ++;             if(second >=60)             {                 second = 0;                 minute++;                 if(minute >=60)                 {                     minute = 0;                 }             }             text = (TextView) findViewById(R.id.textview04);             String strFormat = String.format("%02d:%02d", minute,second);             text.setText(strFormat);                           handler.postDelayed(doUpdateTimer, 1000);         }     };     private Handler autoCountHandler = new Handler();     private Runnable autoCountRunnable = new Runnable() {         public void run() {             count++;             mCountDown.setText(String.valueOf(count));             if(count>0)             {                 autoCountHandler.postDelayed(autoCountRunnable, 500);                               }                           else             {                 if(autoCountHandler != null){                     autoCountHandler.removeCallbacks(autoCountRunnable);                 }             }                       }     }; }

지금 이 코드까지 한걸 실행시키면 핸드폰이 가로방향으로 돌아가면서 실행되고 좌측상단과 우측상단에 

각각 타이머가 동작하게 됩니다. 제가 궁금한건 화면 중앙에 제가 키보드로 w,a,s,d를 누르면 상 하 좌 우 로 

움직이는 사각형을 넣고싶습니다.

package com.example.dodgegame;   import android.app.Activity; import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.os.Bundle; import android.view.KeyEvent; import android.view.View; import android.view.View.OnKeyListener;   public class Gameplayer extends Activity{     int x=100, y = 100;           protected class MyView extends View {         public MyView(Context context) {             super(context);         }         @Override         protected void onDraw(Canvas canvas) {             Paint paint =new Paint();             canvas.drawRect(x,y,x+50,y+50,paint);         }     }           @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         MyView w = new MyView(this);         w.setFocusable(true);         w.setFocusableInTouchMode(true);         setContentView(w);         w.setOnKeyListener(new OnKeyListener() {             public boolean onKey(View v, int keyCode, KeyEvent event) {                 if(event.getAction()==KeyEvent.ACTION_UP) {                     switch (keyCode) {                     case KeyEvent.KEYCODE_J:                         x -= 30;                         break;                     case KeyEvent.KEYCODE_K:                         x += 30;                         break;                     }                     v.invalidate();                     return true;                 }                 return false;             }         });     }   }

그래서 이 코드를 위쪽에 배치를 해보니까 어플이 실행이 안되고 꺼져버립니다. 뭐가 문제인지 고수님들 

답변 부탁드립니다.

직접 코드 돌려보란 말인가요?
