为什么不赶的SQLException SQLiteExcpetion？ [英] Why doesn't SQLException catch SQLiteExcpetion?

问题描述

我有一些code在我，捕获的SQLException Android应用程序之一，但我最近发现，它没有赶上SQLiteException的。显然，SQLiteException的SQLException是一个孩子，所以为什么不被抓？下面是一些code我使用。

I have some code in one of my android apps that catches SQLException, but I've recently found that it's not catching SQLiteException's. Clearly, SQLiteException is a child of SQLException, so why isn't it being caught? Here's some code I'm using.

try {
    ... // something here that will throw an SQLiteException
} catch (SQLException e) {
    e.printStackTrace();
}

是我的假设是正确的，我应该抓住SQLiteException？

Is my assumption correct that I should be catching SQLiteException?

如果它在所有重要的，我使用这个code不是一个活动里面，但是它扩展了应用类里面类。

If it matters at all, i'm using this code not inside of an Activity, but inside of a class that extends the Application class.

作为一个方面说明，我并添加一个额外的赶上（例外五）{} 来看看是否能够工作，它确实正常工作。

As a side note, I did add an additional catch( Exception e ){} to see if that would work and it did indeed work as expected.

推荐答案

有两种类型的SQLException的：

There are two types of SQLException:

android.database.SQLException
java.sql.SQLException

make sure you are using the first not the second.
