You can simply use AlarmManager. By using AlarmManager schedule your task on 12 am at repeating basis. And when AlarmManager Triggers you can perform the database operations.
There are plenty of examples out there. This SO answer can be a good start. you can also check this project. Followings are jsut some search results samples in google first page.

I am working on my final year project where I have requirements to set/re-set some values on Firestore these would be Firebase Firestore APIs calls. and I need these two blocks of codes to be run one block each Monday at 12am and another each 1st day of the month at 12 am.
I will really appreciate the seniors' help in this regard.
Thanks
As pointed out in the comments, you are looking for the WorkManager API. This is a detailed walk-through and this is the actual reference documentation.
If you need to run your code at precisely 12am and the user expects to be notified about it, then you should use the AlarmManager API. However, as mentioned throughout the documentation, alarms greatly interrupt the device's attempts to minimize battery usage.
I want create app android run something in service and repeat after 1 hours but it based on the system clock, 01:00,02:00,.... So, What I have to do? AlarmManager? please help me. thanks all.
Yes, AlarmManager is a decent option. You may also look at JobScheduler as another option. For more details on the ins and outs of using AlarmManager, see this article.
I already have a WebView application connecting clients to a mobile friendly website. For admins, I would like to have a functionality that will run a SQL query (that I already have) every 30 minutes. If it returns true I want a notification to be triggered.
I have done some research and have downloaded a JDBC driver to connect to my MsSql database.
I would like to know the best way to have the app run the query every 30 minutes and conditionally trigger a notification.
Any tips or help is appreciated.
Please let me know if this is a duplicate, I did search before posting.

Use an AlarmManager which allows you to schedule your application to be run at some point in the future, in your case every 30 minutes.
Make sure you run your heavy query in the background using AsyncTask or something like that.
Check this to learn more about AlarmManager https://developer.android.com/training/scheduling/alarms.html and how to use it.

Thanks you for all the answers, i found a tutorial of AlarmManager and it worked as you all said.
Try using AlarmManager in android
The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running. For normal timing operations (ticks, timeouts, etc) it is easier and much more efficient to use Handler.
