Android app and react native app - 28/04/2023 08:57 EDT

I need an Android app plase quto the price and time
When the application is activated, (on off buttoin)
it enters a mode where any incoming calls will be routed through it.
If the user accepts an incoming call, a pre-recorded voice message is played to the caller after hearing
(from a pre-saved folder on the user's device.)
The user and caller can then speak to each other.
After the call ends,
a popup screen appears with the option to send an SMS message.
If the user chooses to send an SMS, a message with a predefined text is sent to the caller even caller number is not saved in phone book
