我的应用程序运行良好，但是当我们第一次升级它时，它显示我们在 google play 的堆栈跟踪中出现错误。

我的代码：

public Cursor getContentData(String pc, String sc) {

        return database.rawQuery("SELECT * FROM content where pc=" + pc
                + " and sc=" + sc + "", null);
    }

错误

正如您的错误所说的那样：

引起：java.lang.IllegalStateException：从第 0 列第 16 行获取字段槽失败

可能第 17 列在您的数据库查询语句中有些缺失。
