This app is to be used as the base app for adding suggested extensions. 4 | 5 | ![Imgur](http://i.imgur.com/NJmF42Yl.png) 6 | 7 | ## Overview 8 | 9 | The app does the following: 10 | 11 | 1. Fetch the books from the [OpenLibrary Search API](https://openlibrary.org/dev/docs/api/search) in JSON format 12 | 2. Deserialize the JSON data for each of the books into `Book` objects 13 | 3. Build an array of `Book` objects and notify the adapter to display the new data. 14 | 4. Define a view holder so the adapter can render each book model. 15 | 16 | To achieve this, there are four different components in this app: 17 | 18 | 1. `BookClient` - Responsible for executing the API requests and retrieving the JSON 19 | 2. `Book` - Model object responsible for encapsulating the attributes for each individual book 20 | 3. `BookAdapter` - Responsible for mapping each `Book` to a particular view layout 21 | 4. `BookListActivity` - Responsible for fetching and deserializing the data and configuring the adapter 22 | 23 | ## Usage 24 | This app is intended to be the base project on top of which new features can be added. To use it, clone the project and import it using the following steps: 25 | 26 | ![Imgur](http://i.imgur.com/joPKoTk.gif) 27 | 28 | ## Suggested Extensions 29 | 30 | 1. Use SearchView to search for books with a title 31 | 2. Show ProgressBar before each network request 32 | 3. Add a detail view to display more information about the selected book from the list 33 | 4. Use a share intent to recommend a book to friends 34 | 35 | ## Libraries 36 | 37 | This app leverages two third-party libraries: 38 | 39 | * [AsyncHttpClient](https://github.com/codepath/AsyncHttpClient) - For asynchronous network requests 40 | * [Glide](https://github.com/bumptech/glide) - For remote image loading 41 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 30 5 | 6 | defaultConfig { 7 | applicationId "com.codepath.android.booksearch" 8 | minSdkVersion 21 9 | targetSdkVersion 30 10 | versionCode 1 11 | versionName "1.0" 12 | 13 | testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" 14 | } 15 | 16 | buildTypes { 17 | release { 18 | minifyEnabled false 19 | proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' 20 | } 21 | } 22 | compileOptions { 23 | sourceCompatibility JavaVersion.VERSION_1_8 24 | targetCompatibility JavaVersion.VERSION_1_8 25 | } 26 | } 27 | 28 | ext { 29 | appCompatVersion = '1.3.0' 30 | glideVersion = '4.12.0' 31 | recyclerViewVersion = '1.2.1' 32 | annotationProcessorVersion = '1.1.0' 33 | asyncHttpClientVersion = '2.1.1' 34 | } 35 | 36 | dependencies { 37 | implementation "androidx.appcompat:appcompat:$appCompatVersion" 38 | implementation "com.codepath.libraries:asynchttpclient:$asyncHttpClientVersion" 39 | implementation "androidx.recyclerview:recyclerview:$recyclerViewVersion" 40 | implementation "com.github.bumptech.glide:glide:$glideVersion" 41 | annotationProcessor "com.github.bumptech.glide:compiler:$glideVersion" 42 | 43 | annotationProcessor "androidx.annotation:annotation:$annotationProcessorVersion" 44 | } 45 | -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # By default, the flags in this file are appended to flags specified 3 | # in /Users/nidhi/Documents/Development/Android SDK/sdk/tools/proguard/proguard-android.txt 4 | # You can edit the include path and order by changing the proguardFiles 5 | # directive in build.gradle. 6 | # 7 | # For more details, see 8 | # http://developer.android.com/guide/developing/tools/proguard.html 9 | 10 | # Add any project specific keep options here: 11 | 12 | # If your project uses WebView with JS, uncomment the following 13 | # and specify the fully qualified class name to the JavaScript interface 14 | # class: 15 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 16 | # public *;
