终结者抛出未捕获的异常(将被丢弃),Android

Question

在logcat中我发现了这些消息,我的应用程序正确运行(没有错误/没有异常/和正确的结果),但为什么这些消息出现在log cat中.我关闭了所有游标.还有一件事,应用程序显示活动有点慢(我的logcat消息中列出了哪些活动),我认为生成这些日志消息需要花费时间.什么是解决方案.

    I/ActivityManager(   63): Displayed activity com.pankaj.myapp/.SelectedContactActivity: 2245 ms (total 2245 ms)

调用者活动正在使用列表视图,并在单击列表项"SelectedContactActivity"活动后调用.

在来电活动中

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.contacts_list_item);
        SimpleAdapter contactAdapter = getAdapter(); // This method returns SimpleAdapter object 
       // Bind to our new adapter.
       setListAdapter(contactAdapter);
    }

protected void onListItemClick(ListView l, View view, int position, long id) {
        super.onListItemClick(l, view, position, id);

        Intent intent = new Intent().setClass(this, AddModifyTag.class);
        intent.putExtra("_id",contactInfo.get("_id"));
        intent.putExtra("name", contactInfo.get("name"));
        intent.putExtra("number", contactInfo.get("number"));
        intent.putExtra("position", position);
        this.startActivityForResult(intent, EDIT_CONTACT_TAGS);
    }

在称为活动

public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
......
......
        Cursor tags;
        db.open();
        tags = db.getContactTags(contactID);
        startManagingCursor(tags);
        .......
        .......
        db.close();
}

Answer 1

我认为你得到这个错误,因为你没有关闭Cursorin onStop()或onDestroy().试着关闭Cursor.你也可以用startManagingCursor()你Cursor,这将帮助你由Android关闭游标.
