AndroidSQLiteDiskIOException磁盘I/O错误（代码522）

昨天来自Crashlytics的我disk I/O error (code 522)在打开数据库时注意到。问题是该崩溃已被16位用户报告了36次。可悲的是我无法重现此错误。这是发生错误的代码片段

SessionDbManager(Context context, String tripDbFileName) {
        this.cOntext= context;
        this.tripDbFileName = tripDbFileName;
        this.tripDbHelper = new SessionDbHelper(this.context, tripDbFileName);
        SQLiteDatabase database = null;
        int attempt = 1;
        while (database == null) {
            try {
                database = this.tripDbHelper.getWritableDatabase(); // here's the error
            } catch (android.database.sqlite.SQLiteException e) {
                Crashlytics.logException(e);
                XLog.e("Failed to load history data from database ", e);
                if (attempt == 5) throw e;
            }
            attempt++;
        }
        db = database;
    }

这是堆栈跟踪

我已经阅读了有关I / O错误的信息，并找到了两个可能的答案，我认为这是因为用户的设备可用空间不足。但是这是来自两个应用程序用户的一些图片

因此，这绝对不是存储问题：(有什么想法可以解决这个问题？
