我刚开始安装android编程

当我运行项目时，即使logcat没有发出任何错误信号，也不会出现地图我使用Google API（Google Inc.）模拟器级别17 这是主要的活动

public class MainActivity extends MapActivity {

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

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
    protected boolean isRouteDisplayed() {
        return false;
        }
}
