I have a simple android app with a realm db/2 tables. 我有一个带域db / 2表的简单android应用。

When I uninstall my application, all the realm databases/tables are deleted from my app, or not? 当我卸载应用程序时，所有领域数据库/表都从我的应用程序中删除了吗？

1 个解决方案

Fundamentally, yes . 从根本上讲，是的。 The database and tables are deleted on uninstall. 卸载时将删除数据库和表。

However, there exists cases when they are not deleted. 但是，存在不删除它们的情况。

When you uninstall the application, your /data/data/com.example.acme folder should be erased. 卸载应用程序时，应删除/data/data/com.example.acme文件夹。 If you're specifically opening the Realm on the external storage (and not inside of your internal storage dedicated data folder as per context.getFilesDir()), then the Realm file will not be removed. 如果您专门在外部存储设备上打开Realm（而不是根据context.getFilesDir（）在内部存储设备专用数据文件夹内部），则不会删除Realm文件。

The Realm.getDefaultInstance() and Realm.getInstance(Context) calls open the Realm in getFilesDir(), which means it should be deleted along with the application. Realm.getDefaultInstance（）和Realm.getInstance（Context）调用在getFilesDir（）中打开领域，这意味着应与应用程序一起将其删除。
