<com.example.canavstest.Draw2d
    android:id="@+id/game"
    android:layout_width="match_parent"
    android:layout_height="400dp"
    android:layout_gravity="center_vertical|center_horizontal" />

public class MainActivity extends Activity {

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

}

public class Draw2d extends View{

public Draw2d(Context context) {
    super(context);
    // TODO Auto-generated constructor stub
}
protected void onDraw(Canvas canvas){
    super.onDraw(canvas);
    Paint paint = new Paint();
    paint.setStyle(Paint.Style.FILL);

Looks like you spelt your packageName incorrectly. Check your AndroidManifest.

com.example.canavstest.Draw2d

Should probably be

com.example.canvastest.Draw2d

Notice the spelling of canvas

Edit: Also, you have not implemented the constructor that the LayoutInflater calls. Add this.

public Draw2d(Context context, AttributeSet attrs){
    super(context, attrs);
}
