Question

在我的开发者控制台的Crashes＆amp; ANR选项卡中获取此错误代码。这是完整的StackTrace：

我的课程中指出的错误代码是：

at com.xxxx.xxx.Database.open（Database.java:239）

        String BDFAV_NAME = "db_fav";
        int BDFAV_VERSION = 1;
        DBHelper = new DbHelper(Context, BDFAV_NAME, BDFAV_VERSION);
        BDFav = DBHelper.getWritableDatabase(); //this is the line 239

at com.xxxx.xxx.Infodata.isItemFavorite（Infodata.java:1051）

boolean isItemFavorite() {
    bDFav.open(); // line 1051
    ......
}

at com.xxxx.xxx.Infodata.onCreateOptionsMenu（Infodata.java:602）

isItemFavorite()

和bDFav位于onCreateView()

上

activityContext = getActivity().getApplicationContext();
 bDFav = new Database(activityContext, true);

似乎无法理解为什么我收到此错误。有什么想法吗？
