Abstract - This paper aims to demonstrate the creationand evaluation of a mobile application for creating student profiles. Mobile technology is a rapidly expanding industry that is closely related to our daily lives and jobs. The plan is to develop an app for college students that allows them to display their profiles, which include interests, contact information, personal data, skills, and skill sets, to faculty and industry recruiters. Students canexplainthemselves much more quickly this way. With the help of this application, students can discuss other important topics with the faculty members by leaving their introduction information in the app. By entering their introduction details into the app, students can use this application to talk with faculty members about other crucial subjects.
Key Words: AndroidStudio,Multiplescreens,User-friendly Application,PersonalInformation
1. INTRODUCTION
Themajorityofmobileplatformsusedaroundtheworldrun the Android operating system. Android is the operating systemforhundredsofmillionsofmobiledevicesinmore than190differentcountries.Itwillholdroughly75%ofthe global market share by the end of 2020, and this trend is onlyaccelerating. Android,whichwasinitiallydevelopedby the business known as the Open Handset Alliance, was created by modifying the Linux kernel and other opensourcesoftware.Beforebuyingtheentirecompanyin2005, Googleprovidedfundingfortheproject.InSeptember2008, thefirstdevicewiththeAndroidoperatingsystemwasmade availableforpurchase.Becauseoftheextensivefeaturesetit offers,AndroidhasdominatedthemobileOSmarket.userfriendly, has a sizable community, allows for greater customization,andalotofmanufacturersproduceAndroidcompatible smartphones. user-friendly, has strong communitysupport,allowsforgreatercustomization,and manybusinessesproduceAndroid-compatiblesmartphones.
