How to Automatically Update Your Android SQLite Database Every 24 Hours

Creating an expiry tracking application can be quite challenging, especially if it requires you to keep track of time-sensitive information, such as how many days before items expire. If you need to update the expiry days left in a SQLite database automatically every 24 hours to make effective data comparisons and ensure accuracy, you are in the right place.

In this guide, we will guide you step-by-step on implementing a solution to automatically update your SQLite database every 24 hours. This way, the expiry days left will be updated efficiently, ensuring your application remains informative and up-to-date.

Problem Overview

Your application needs to perform the following tasks:

Store the expiry dates of items.

Compare these expiry dates to the current date daily.

Update the expiryDaysLeft column in your SQLite database to reflect the days remaining.

Ensure that the database reflects an accurate status (updating to zero when an item expires).

To achieve this seamless functionality, we can leverage the WorkManager API in Android, which is suited for background tasks that need to be executed periodically.

Solution Breakdown

Step 1: Create a Worker Class

The first step involves creating a worker class that will contain the logic for updating the database. Below is a simple template you can follow:

Step 2: Schedule the Worker with PeriodicWorkRequest

Once you have your worker class set up, you can then schedule it to run every 24 hours using the PeriodicWorkRequestBuilder. The following code snippet demonstrates how to do this:

This code sets up a request to invoke the worker every 24 hours, enabling you to check and update the expiry information in your SQLite database.

Step 3: Cancel Work if Necessary

Should there be a scenario where you need to stop the periodic updates, you can easily cancel the work by using the following code:

This flexibility ensures that you have control over your scheduled tasks according to the needs of your application.

Conclusion

Keeping your database updated automatically is crucial for any application that relies on time-sensitive data. With the above steps, you can effectively utilize WorkManager to run background tasks and ensure your SQLite database reflects accurate expiry information every day. This method not only enhances user experience but also ensures data integrity in your expiry tracking application.
