Add an "Exit" button on the last activity of the app.
When the user chooses to exit, they must enter their feedback in a text field.
Save this feedback to Firebase Firestore
Apply sentiment analysis to the feedback to determine the user’s satisfaction level (e.g., satisfied, not satisfied, somewhat satisfied).
Send an email to your manager (you may use your own email address) containing a report with the user’s information and their satisfaction result.
Please provide samples of your previous work.
