in order to get timestamp we cant use read sms and call logs permission in android anymore we can just use broadcast receiver to take the timestamp by using gettimestampinmillis() function. we can also use sms retriever to get the timestamp it is the alternative for read sms permission offered by google itself. its not possible to directly write data in broadcast receiver. either you have to store it in shared preferences or in room database to store the data and later use it in saving permissions like recieve sms is also not required while using broadcast the permissions like read sms and call logs are the core permissions and are available in use only for old customers by google. something about REACTJS its a library used to make single page webpages. it uses css, bootstrap and its so simple and fast that anyone can learn it easily there are two things with state and stateless with state are used in class while stateless are used in functions if we want to use states in function then we can use hooks to do so, as making class again and again is not a good habit so hooks are used to do so We can make our local api and then test it on postman. If we wanna fetch some details from api we can simply use GET operation and can get the particular information from that Other then GET,we have PUT, POST, DELETE operations used according to our needs For further details you can check the official page of reactJS hacktober fest pr 1
