如何将Realm数据库文件与我的应用程序捆绑在一起以进行安装部署 [英] How can I bundle a Realm database file with my app to deploy with installation

问题描述

我有一个大约50k记录的数据集，我想将其放入Realm数据库中.我不确定如何在Realm中创建此数据库并将其与App捆绑在一起，以便文件可以从一开始(安装)就驻留在设备中.

I have a data set of around 50k records which I want to put in a Realm database. I am unsure of how can I make this DB in Realm and bundle it with the App so that the file can reside from the very start (installation) in the device.

推荐答案

您可以将Realm文件放入资产文件夹中，并在首次打开应用程序时将其复制.这里有一个有关如何执行此操作的示例: https://github.com/realm/realm-java/blob/master/examples/migrationExample/src/main/java/io/realm/examples/realmmigrationexample/MigrationExampleActivity.java#L57

You can put a Realm file in your assets folder and copy it the first time you open the app. There is an example on how to do that here: https://github.com/realm/realm-java/blob/master/examples/migrationExample/src/main/java/io/realm/examples/realmmigrationexample/MigrationExampleActivity.java#L57

然后您可以使用SharedPreferencs/另一个Realm或类似的域来保存一个布尔值，以指示该Realm文件已被复制.

You can then use SharedPreferencs/another Realm or similar to save a boolean to indicate that the Realm file has been copied.

现在，我们在Android之外还没有任何API可以使用，但是创建预填充数据库的一种方法是制作一个小型应用程序，然后在模拟器上运行该应用程序，然后使用ADB提取数据库: 如何在领域浏览器?

Right now we don't have any API working outside Android, but one way to create a prepopulated Database is to make a small app that does it, run that that app on an emulator and then use ADB to pull the database: How to view my Realm file in the Realm Browser?
