Usually, we are under the misconception that scientists are always busy inventing new things. However, like any other person, a scientist also learns something new everyday. In fact, the very nature of their jobs makes them passionate to learn something each moment of their lives! In the quest to learn about the latest technologies and to explore more, Ramprasad Chakraborty, a scientist at Indian Space Research Organisation underwent Android Online training at Edureka and ended up developing a dynamic Android app on Online Book Shopping!
A Brief Background:
This is what he felt about the Android Online training at Edureka…
Let’s peep into his Android App!
As we all know that Android is covering a huge mobile platform market over the last few years, Ramprasad’s Android project demonstrates how an ‘Online Book Shopping‘ application can be developed for Android platform.
Key Activities of Ramprasad’s Android project:
Activity 1 (Login):
The first activity in this Android App is the login screen which is used to authenticate a registered user on receiving the email address and password. The login screen checks in SqLite database for verifying the credentials of the valid user each time a user tries to login into POS. If the user enters an incorrect email id or password, it shows “Login failed…” error message. There is also an option for new user to register themselves to the POS, before they can login into the system. On successful login, the screen takes the user to the Booklist Activity (Activity 3).
Activity 2 (Register):
The second activity of the application is meant for new user registration. User comes to this activity on clicking the ‘SignUp’ button on the Login page (Activity 1). This activity asks for the email id, user name and password information from the new user, performs validation of inputs and then accepts the registration. On successful registration, a message is displayed as “Registered successfully…” and takes the user to the Booklist Activity (Activity 3).
Activity 3 (Booklist):
This is the third and one of the main activities in this Android App. It shows a list of all the books for the default category – ‘Academics’, with Book Title, Book Price and Thumbnail information. A new category such as ‘comics’ can be selected from the spinner and list gets updated accordingly. On selection of a book from the list, the application takes the user to the Cart Activity (Activity 4) after user confirmation.
Activity 4 (Cart):
The Cart Activity shows a list of books selected by the user for purchase. It also shows the total amount of books selected including the tax. From here, the user can select ‘More shopping’ to go to the Booklist Activity again for more books or can ‘Checkout’ if the user doesn’t require more books and enter the Summary Activity (Activity 5).
Activity 5 (Summary):
This is the final activity of this Android application. All the selected books, prices, subtotal, total including taxes and user information are displayed on the screen. User confirms the purchase by clicking the ‘Done’ button. On confirming this, the purchase data is stored in the log file and the application starts freshly from the Login Activity (Activity 1).
It is not the final Android project that matters the most, what is worth noting is the fact that people from different walks of lives are opting to Learn Android by looking out for Android Online training and having great FUN! Edureka constantly endeavors to provide rich and interactive learning experience to its learners through our unique Learning Methodology.
