在Android中使用存在SQLite数据库 [英] Using existed SQLite database in Android

问题描述

我的问题是在我的Andr​​oid应用程序中使用SQLite的存在的数据库。
要管理它，我用了著名的文章中，描述我的任务 - 的http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications

My problem is in using the existed sqlite-database in my android application. To manage it, I used the well-known article, that describes my task - http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications

虽然这个应用程序启动时，我得到了错误：

While this app starts, I'm getting the error:

08-17 06:35:18.416: ERROR/Database(286): sqlite3_open_v2("data/data/com.jeston.existed.sqlite/databases/android_test_db.db", &handle, 1, NULL) failed
08-17 06:35:18.437: ERROR/AndroidRuntime(286): Uncaught handler: thread main exiting due to uncaught exception
08-17 06:35:18.457: ERROR/AndroidRuntime(286): android.database.sqlite.SQLiteException: unable to open database file 

我怀疑我用错了路径mydatabase.I放下我android_test_db文件夹的资产，并写在博客上，给了

I suspect that I use wrong path to mydatabase.I put down my android_test_db file to assets folder and, as written in the blog, gave the

private final static String DB_PATH = "data/data/com.jeston.existed.sqlite/databases/";
private final static String DB_NAME = "android_test_db.db";

所以，我的问题是，这些pathes正确或没有？或者可能是，我在共同的错误的方式？

So, my question is these pathes are correct or no? or may be, i'm on the wrong way in common?

感谢大家。

推荐答案

该数据库的扩展名必须是因为它是完全一样的。
此外，我认为你的主要问题是，你指定了错误的包。它必须是根包。尝试：

The db name extension has to be exactly the same as it is. Moreover, I think your main problem is that you specify the wrong package. It has to be the root package. Try that:

private final static String DB_PATH = "data/data/com.jeston.existed/databases/";
