Book Library App using Google Books API. If you are looking for building a book library app and you want to load a huge data of books then for adding this feature, you have to use a simple API which is provided by Google, and of course, it’s free. In this article, we will take a look at the implementation of this API in our Android App.
What we are going to build in this article? We will be building a simple application in which we will be searching different types of books and we will get to see the list of books related to that topic in our RecyclerView. For searching these books we will be using a free API provided by Google which holds a huge collection of books. A sample video is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language. Step by Step Implementation Step 1: Create a New Project
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.
Step 2: Add the dependency for Volley in your Gradle files Navigate to the app > Gradle Scripts > build.gradle file and add below dependency in the dependencies section.
implementation ‘com.android.volley:volley:1.1.1’
implementation ‘com.squareup.picasso:picasso:2.71828’
After adding the below dependencies in your gradle file now sync your project and now we will move towards our activity_main.xml file. As we will be using volley to fetch data from our API and Picasso image loading library to load images from URL.
Step 3: Adding permissions for the Internet
Navigate to the app > AndroidManifest.xml and add the below permissions to it. open first.xml As we will be loading the books from API so we have to request Internet permissions from the user. For that add the permissions for the internet in AndroidManifest.xml.
Step 4: Working with the activity_main.xml file
Go to the activity_main.xml file and refer to the following code. Below is the code for the activity_main.xml file. Open second.xml Step 6: Create a new layout resource file
Go to the app > res > layout > right-click > New > Layout Resource File and name the file as book_rv_item and add the following code to this file. Open third.xml
Step 7: Creating an Adapter class for setting our data to the item of RecyclerView
Navigate to the app > java > your app’s package name > Right-click on it Click on New > Java class and name it as BookAdapter and add below code to it. Comments are added in the code to get to know in more detail. Open java file. Execute it. Desired output is obtained. Thankyou
