我将要创建两个具有相同 SQLite 数据库的应用程序。我经历了this关联。但这没有意义。我必须从两个应用程序更新数据库。请提出一种或多种更好的方法。

Answer 1

您应该阅读有关Content Provider的内容

Content providers are one of the primary building blocks of Android applications, providing content to applications. They encapsulate data and provide it to applications through the single ContentResolver interface. A content provider is only required if you need to share data between multiple applications. For example, the contacts data is used by multiple applications and must be stored in a content provider. If you don't need to share data amongst multiple applications you can use a database directly via SQLiteDatabase.
