Question

我正在尝试在我的3个应用程序之间共享数据库。目前使用内容提供程序存在一些实际困难，因此我使用android：sharedUserId，以便我可以在我的3个应用程序之间共享数据库：

我在第3个应用程序中遇到以下异常，当我尝试调试时，日志没有打印出来。我已经清理了项目，删除了APK并尝试过，但仍然没有运气。以下是我得到的例外：

我想知道为什么它在一个应用程序中起作用而在另一个应用程序中不起作用。由于这个原因，应用程序不会崩溃，但我仍然认为，除了设置布局之外，由于此异常，活动类中没有任何反应。以下是我的创造：

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


    //code to make connectivty with shared db.
    Context sharedContext = null;
    try {
        // change package name if required
        sharedContext = this.createPackageContext("com.nykkos.personalize", Context.CONTEXT_INCLUDE_CODE);
        if (sharedContext == null) {
            return;
        }
    } catch (Exception e) {
        e.printStackTrace();
        return;
    } 

    SQLiteDBHelper  dbHelper=new SQLiteDBHelper(sharedContext);
    try {
        dbHelper.createDataBase();
        dbHelper.openDataBase();
    } catch (Exception e) {
        e.printStackTrace();
    }

    System.out.println("Before db call in dockbar");

    appList=dbHelper.getList();

在上面的代码中，布局已设置，但不打印Systeem.out.println。

有人可以指导我如何解决此问题
