In this project, we will be creating an Advanced CRM Android app that has two modules, Employer and Employees.<\/p>\n<p>The Employer can create tasks, delete tasks, and register new users to the app. The Employees can view the tasks and update their status, whether they are complete or incomplete.<\/p>\n<p>This app will be designed to streamline communication between employers and employees, thereby enhancing productivity and efficiency.<\/p>\n<h3>About Android CRM App<\/h3>\n<p>The objective of this project is to guide you through the process of creating an Advanced CRM Android app that enables employers to create tasks, delete tasks, and register new users to the app. Employees can view the tasks assigned to them and update their status, whether they are complete or incomplete.<\/p>\n<p>By the end of this project, you should be able to create a basic Advanced CRM app that can be customized to fit your personal or professional needs.<\/p>\n<h3>Prerequisites for CRM App using Android<\/h3>\n<p>To follow along with this project, you will need the following:<\/p>\n<ul>\n<li>A computer running Android Studio.<\/li>\n<li>Basic knowledge of Java and Android app development using Android Studio.<\/li>\n<li>An Android device or emulator to test the app<\/li>\n<\/ul>\n<h3>Download Android CRM App Project<\/h3>\n<p>Please download the source code of Android CRM
