Question

在我的应用中，我有SyncAdapter使用ContentProvider将数据放入SQLiteDatabase。几个月来，一切都运转良好。在我添加了第二种方法来更新来自GCM推送通知的ContentProvider后，我开始收到某些用户的崩溃报告，例如

android.database.sqlite.SQLiteDiskIOException: disk I/O error (code 3850)

OR

android.database.sqlite.SQLiteDiskIOException: disk I/O error (code 778)

以及与sqlite相关的其他几个例外。

虽然我听说Sqlite是同步的，我们不必担心，但我确实得到了这些错误，指出我需要以某种方式进行同步。有人处理过这个问题吗？

编辑：这是一个示例堆栈跟踪

Answer 1

只需在内容提供商代码中使用一个帮助程序即可。因此，始终将1个帮助程序连接到1个数据库，您将不会遇到任何问题。

如果您不提供对其他应用程序的访问权限，则无需使用内容提供商。

在我决定切换到ORMLite之前，我一直在使用内容提供商。到目前为止，它在我的所有项目中都运行良好。也许检查一下。
