Android Studio: java.lang.runtimeexception: невозможно начать деятельность ⇐ Android

[Anonymous]

Я делаю игру для Android, в которую я сделал модель в Java (на Eclipse).

Я на самом деле пытаюсь нарисовать сетку, но когда я работаю, у меня есть java.lang.runtimeexception: невозможно начать активность
Я не понимаю, где проблема, она говорит, что проблема - это из SetContentView (r.layout.Activity_main)
Тогда это моя игра, которую я рисую и делаю действия: < /p>
public class GameView extends SurfaceView implements SurfaceHolder.Callback{
Game gam;
Paint paint=new Paint();
int canvasWidth;
int cellSize;

public GameView(Context context, AttributeSet attributeSet){
super(context,attributeSet);
getHolder().addCallback(this);
getGam(context);
}

public GameView(Context context){
super(context);
getHolder().addCallback(this);
this.getGam(context);
}

public final void getGam(Context context){
gam=(Game)(context.getApplicationContext());
}

@Override
public void surfaceCreated(SurfaceHolder holder) {

}

public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
canvasWidth=width;
cellSize=width/5;
reDraw();
}

public void reDraw(){
Canvas c=getHolder().lockCanvas();
if(c!=null){
this.onDraw(c);
getHolder().unlockCanvasAndPost(c);

}
}

@Override
public boolean onTouchEvent(MotionEvent event) {
int x=(int)event.getX();
int y=(int)event.getY();

int action=event.getAction();
TenGame theGame=gam.getTenGame();
switch(action){
case MotionEvent.ACTION_DOWN:{
theGame.getSelectedGroup();
}
default:
return false;
}

}

@Override
public void surfaceDestroyed(SurfaceHolder holder) {

}
@Override
public void onDraw(Canvas canvas){
paint.reset();
TenGame theGame=gam.getTenGame();
canvas.drawColor(Color.GRAY);

paint.setColor(Color.BLACK);
for(int x=0;x
