If you have a relatively small collection of key-values that you'd like to save, you should use the SharedPreferences APIs, but it is not multi-process safe.

SharedMemory API (which introduce in Android 8) allows you to reading and/or writing file descriptor using NDK, since the SharedMemory object is Parcelable, you can easily pass it to another process through AIDL. It's a great way to set the memory protection and share large amounts of data between apps or between multi-process within a single app.

ContentProviders were constructed for sharing data between apps. A content provider presents data to external applications as one or more tables that are similar to the tables found in a relational database. You can create your own ContentProvider which stores the data with a SharedPreference, you don't have to use SQLite. The ContentProvider APIs are well suited for SQL type implementations.
