Answer 3

mapView.onCreate(savedInstanceState); 报错的是这一行

Answer 4

说一下我的经验，这个问题真是整死我了，哈哈，开发环境 AS2.1， 加入的Map总是直接异常退出，后来把工程Clean一下就行了。真是莫名其妙。

Answer 5

我原来遇到过这样的问题，第一你先试着把
        //地图的显示
        mMapView = (MapView) findViewById(R.id.map);//找到地图控件
        mMapView.onCreate(savedInstanceState);// 此方法必须重写
        aMap = mMapView.getMap();//得到一个map对象
写到一起看看行不行，

Answer 6

不行就重新下载jar包，直接用demo里lib的
