SMS after install application

Question

I created an application and immediately after install I need to send a text message to a central server configuration.

How I can do that?

In applications such as WhatApps, just after installing you receive an SMS configuration. Anyone know how to do that.

Answer 1

check for a boolean flag in shared preferences .

do stuff if not exist and insert this flag to sharedPrefeences .

sharedPreferences get deleted if user clears the data of app so better approach i will say is

you manage device_id on server and do the same thing .
