Ever wanted to avoid some contacts from entering your WhatsApp or any IM contact list? But couldn't delete them from your phone book because you needed them for work/business calls?
Now you can have a second space where you can save them and get notified about their name when they call you.
This flow works as follows:
-Grabs incoming caller number
-Searches the Sqlite Database if the number is already saved by you
-If found, the saved caller name will be displayed in the notification
You will need to add such contacts manually into this flow. All your saved contacts will be in contacts.sqlite file under Documents. You can grab and read that file with any Sqlite reader app anytime.
For the motivation behind this flow, read this https://android.stackexchange.com/q/187425
