我的主要活动（比如 A）提出了从 ContactsContract 获取 ContactID 的意图

startActivityForResult(new Intent(Intent.ACTION_PICK, contactsContract.Contacts.CONTENT_URI),PICK_CONTACT);

返回（onActivityResult（int reqCode，int resultCode，Intent data））时，我正在使用“数据”中的详细信息来查询联系人

 if (resultCode == Activity.RESULT_OK) {
        Uri contactData = data.getData();
        Cursor c =  managedQuery(contactData, null, null, null, null);
        ......

我的代码适用于 Android 2.x。但是，此代码在 ICS (Android 4.x) 中崩溃，同时恢复主 Activity(A)。我不确定是否是由于已弃用的“managedQuery”。有人可以提供一些解决方案吗，我被卡住了，甚至无法找到导致错误的行，因为 Log cat 甚至没有显示错误行号。它只是说 原因：android.database.StaleDataException：试图在游标关闭后访问它。 提前谢谢乔希

在完成游标的要求后，我已经尝试了上面的代码。问题仍然存在。我的日志猫说如下

听起来这是个问题：

* android.database.staledataexception : 访问关闭游标

您似乎正在使用 managedQuery 获取游标。

我在恢复应用程序时遇到了问题，由于某种原因，Icecream Sandwich 中的应用程序没有正确关闭游标。修复方法是在使用所有游标后立即对它们执行此操作：

if (cursor != null && !cursor.isClosed()) {  
  myActivity.stopManagingCursor( cursor );   
  cursor.close(); 
}

API startManagingCursor/stopManagingCursor 已弃用，是问题的根本原因。例如，请将此注释掉并验证。
