I need an Android app. I already have a design for it, I just need it to be built.
I wanted to build an android app for automated phone call/SMS
a call should be made to the single/multiple contact numbers with the recorded voice in a specified time and this app should work only in offline.
by chance if the number is busy then a SMS has to be sent to that single/multiple contact numbers
all these steps should be automated (without manually doing everything)
