I could understand the Android library taking a bit longer to execute than the browser but it should not be several hundred times slower. 5- Sqlite Manager Sqlite manager is a simple SQLite debugging tool for Android, to help developers access, manage, perform SQL queries on Android apps. Migrating Android Apps from Realm Java SDK to Kotlin SDK. When I execute the same query without the DISTINCT option, it executes in about 1 second. Realm is a fast, scalable alternative to SQLite with mobile to cloud data sync that makes. When you use this class to obtain references to your database, the system performs the potentially long-running operations of creating and updating the database only when needed and not during app startup.

Supports MySQL, Postgres, Microsoft SQL Server, H2, Derby, HSQLDB, and Sqlite and can be.

I use the following query to retrieve the list of stations (from a table containing approximately 50,000 entries for stop times): SELECT DISTINCT SUBSTR(stops._id, 0, LENGTH(stops._id)) as _id, stops.stop_name
I'm developing an app that takes raw transit data and displays the upcoming train schedule.
