Android Contact Manager App

I’m connected to a body area network which creates problems for my cellphone. I cannot keep contacts in my cellphone contact list for long periods of time.

I need a simple android app to modify the contact list in my cellphone. It involves keeping my contacts in a SQLite database & using a script to copy contacts to cellphone contact list, wait specified time, delete all contacts in cellphone phone and repeat with a specified time. Both specified times found in the settings table in the SQLite file. I’d like the script to run on startup without user intervention. Can be disabled if settings table has 0 for disable. Program exits when disable equals 1. I would get this script going myself but have too many hurdles with being slowed down by nanomaterials. I plan on using Sqlite Master from the android store to add contacts to the contacts table and adjust settings within the settings table to save time creating a graphical interface.

SQLite database contains:

Contacts table with columns for:
Id, name, number, email, url/website

Settings table with columns for:
Disable, Time in contacts list, Time out of contacts list


I’m expecting well documented source code & compiled app to run on Android 9 operating system with Samsung J2.

Please ask questions if any clarification is needed.
