Can we use one database for two or more application

I am about to create two applications which have the same SQLite database. I went through this link. But it does not make sense. I have to update the database from both applications. Please suggest one or more better ways.

Content Provider is a great way to share database with other applications.

When you create a Content Provider, you can define which part of your database can be shared as well.

A Content Provider has following parts- 1. A class that extends ContentProvider class 2. An Authority that distinguishes this ContentProvider from others on the Android O.S. 3. A Contract class that holds Uri to tables and columns that you want to share with other applications 4. A ContentResolver to access data from a ContentProvider 5. Set of user defined permissions to write to and read from a shared ContentProvider. Permissions allow only those apps that you authorize to access your ContentProvider

Here is a simple tutorial about the use of ContentProvider and how to share your database with other applications- https://www.tutorialspoint.com/android/android_content_providers.htm

You should read about Content Provider

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.
