我终于做到了!!我已经使用这个链接帮助在Android应用程序中使用自己的SQLite数据库，但必须稍微改变一下。

If you have many packages you should put the master package name here: private static String DB_PATH = "data/data/masterPakageName/databases"; I changed the method which copies the database from local folder to emulator folder! It had some problem when that folder didn't exist. So first of all, it should check the path and if it's not there, it should create the folder. In the previous code, the copyDatabase method was never called when the database didn't exist and the checkDataBase method caused exception. so I changed the code a little bit. If your database does not have a file extension, don't use the file name with one.

它对我很有用，我希望它对你也有用

创建和更新数据库有两个选项。

One is to create a database externally, then place it in the assets folder of the project and then copy the entire database from there. This is much quicker if the database has a lot of tables and other components. Upgrades are triggered by changing the database version number in the res/values/strings.xml file. Upgrades would then be accomplished by creating a new database externally, replacing the old database in the assets folder with the new database, saving the old database in internal storage under another name, copying the new database from the assets folder into internal storage, transferring all of the data from the old database (that was renamed earlier) into the new database and finally deleting the old database. You can create a database originally by using the SQLite Manager FireFox plugin to execute your creation sql statements.

另一种选择是从sql文件内部创建数据库。这没有那么快，但是如果数据库只有几个表，用户可能不会注意到延迟。通过更改res/values/strings.xml文件中的数据库版本号来触发升级。然后通过处理一个升级sql文件来完成升级。数据库中的数据将保持不变，除非它的容器被删除，例如删除一个表。

下面的示例演示了如何使用这两种方法。

下面是一个create_database示例。sql文件。它将被放置在内部方法的项目资产文件夹中，或复制到SQLite管理器的“Execute SQL”中，以创建外部方法的数据库。(注意:注意关于Android需要的表的注释。)

--Android requires a table named 'android_metadata' with a 'locale' column
CREATE TABLE "android_metadata" ("locale" TEXT DEFAULT 'en_US');
INSERT INTO "android_metadata" VALUES ('en_US');

CREATE TABLE "kitchen_table";
CREATE TABLE "coffee_table";
CREATE TABLE "pool_table";
CREATE TABLE "dining_room_table";
CREATE TABLE "card_table"; 

下面是一个update_database示例。sql文件。它将被放置在内部方法的项目资产文件夹中，或复制到SQLite管理器的“Execute SQL”中，以创建外部方法的数据库。(注意:本例中包含的SQL解析器将忽略所有三种类型的SQL注释。)

--CREATE TABLE "kitchen_table";  This is one type of comment in sql.  It is ignored by parseSql.
/*
 * CREATE TABLE "coffee_table"; This is a second type of comment in sql.  It is ignored by parseSql.
 */
{
CREATE TABLE "pool_table";  This is a third type of comment in sql.  It is ignored by parseSql.
}
/* CREATE TABLE "dining_room_table"; This is a second type of comment in sql.  It is ignored by parseSql. */
{ CREATE TABLE "card_table"; This is a third type of comment in sql.  It is ignored by parseSql. }

--DROP TABLE "picnic_table"; Uncomment this if picnic table was previously created and now is being replaced.
CREATE TABLE "picnic_table" ("plates" TEXT);
INSERT INTO "picnic_table" VALUES ('paper');

下面是要添加到/res/values/strings.xml文件中的数据库版本号条目。

<item type="string" name="databaseVersion" format="integer">1</item>

下面是一个访问数据库并使用它的活动。(注意:如果数据库代码使用了大量资源，则可能需要在单独的线程中运行。)

package android.example;

import android.app.Activity;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;

/**
 * @author Danny Remington - MacroSolve
 * 
 *         Activity for demonstrating how to use a sqlite database.
 */
public class Database extends Activity {
     /** Called when the activity is first created. */
     @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        DatabaseHelper myDbHelper;
        SQLiteDatabase myDb = null;

        myDbHelper = new DatabaseHelper(this);
        /*
         * Database must be initialized before it can be used. This will ensure
         * that the database exists and is the current version.
         */
         myDbHelper.initializeDataBase();

         try {
            // A reference to the database can be obtained after initialization.
            myDb = myDbHelper.getWritableDatabase();
            /*
             * Place code to use database here.
             */
         } catch (Exception ex) {
            ex.printStackTrace();
         } finally {
            try {
                myDbHelper.close();
            } catch (Exception ex) {
                ex.printStackTrace();
            } finally {
                myDb.close();
            }
        }

    }
}

这里是数据库助手类，如果需要，数据库将在其中创建或更新。(注意:Android要求你创建一个扩展SQLiteOpenHelper的类，以便使用Sqlite数据库。)

Android已经提供了一种版本感知的数据库管理方法。这种方法已经在Android应用程序的BARACUS框架中得到了利用。

它使您能够在应用程序的整个版本生命周期中管理数据库，能够将sqlite数据库从任何以前的版本更新到当前版本。

此外，它还允许您运行SQLite的热备份和热恢复。

我不是100%确定，但是针对特定设备的热恢复可能使您能够在应用程序中发布准备好的数据库。但我不确定数据库二进制格式，这可能特定于某些设备，供应商或设备代。

因为这些东西是Apache许可证2，所以可以随意重用代码的任何部分，这些代码可以在github上找到

编辑:

如果您只想传送数据，可以考虑在应用程序第一次启动时实例化和持久化pojo。BARACUS有一个内置的支持(内置的键值存储配置信息，例如。"APP_FIRST_RUN"加上一个后上下文引导钩子，以便在上下文上运行后启动操作)。这使得你可以在应用中使用紧密耦合的数据;在大多数情况下，这符合我的用例。

SQLiteAssetHelper库使得这个任务非常简单。

作为gradle依赖项添加它很容易(但Jar也可用于Ant/Eclipse)，它的文档可以在以下地址找到: https://github.com/jgilfelt/android-sqlite-asset-helper

注意:这个项目不再维护如上所述的Github链接。

如文档中所述:

Add the dependency to your module's gradle build file: dependencies { compile 'com.readystatesoftware.sqliteasset:sqliteassethelper:+' } Copy the database into the assets directory, in a subdirectory called assets/databases. For instance: assets/databases/my_database.db (Optionally, you may compress the database in a zip file such as assets/databases/my_database.zip. This isn't needed, since the APK is compressed as a whole already.) Create a class, for example: public class MyDatabase extends SQLiteAssetHelper { private static final String DATABASE_NAME = "my_database.db"; private static final int DATABASE_VERSION = 1; public MyDatabase(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); } }

目前还没有办法预先创建一个SQLite数据库来与apk一起发布。最好的方法是将适当的SQL保存为资源，并从应用程序中运行它们。是的，这会导致数据的重复(同样的信息作为资源和数据库存在)，但目前没有其他方法。唯一的缓解因素是apk文件被压缩了。我的经验是908KB压缩到268KB以下。

下面的帖子有我找到的最好的讨论/解决方案，其中有很好的示例代码。

http://groups.google.com/group/android-developers/msg/9f455ae93a1cf152

我把我的CREATE语句存储为一个字符串资源，用Context.getString()读取，并用SQLiteDatabse.execSQL()运行。

我将插入的数据存储在res/raw/inserts中。sql(我创建了sql文件，7000+行)。使用上面链接的技术，我输入了一个循环，逐行读取文件，并将数据连接到“INSERT INTO tbl VALUE”，并执行另一个sqlitedatbase . execsql()。当它们可以连接时，保存7000个“INSERT INTO tbl VALUE”是没有意义的。

在模拟器上大约需要20秒，我不知道在真正的手机上需要多长时间，但它只发生一次，当用户第一次启动应用程序时。

我写了一个库来简化这个过程。

dataBase = new DataBase.Builder(context, "myDb").
//        setAssetsPath(). // default "databases"
//        setDatabaseErrorHandler().
//        setCursorFactory().
//        setUpgradeCallback()
//        setVersion(). // default 1
build();

它将从assets/databases/myDb.db文件创建一个dataBase。 此外，你会得到所有这些功能:

从文件加载数据库 同步访问数据库 使用SQLite - Android通过requery, Android特定分发最新版本的SQLite。
