Library

In this project, we use many libraries to help make development easier such as:

Firebase​

We use 3 modules from Firebase include:

Crashlytics​

Firebase Crashlytics, a real time crash reporting tool, helps you prioritize and fix your most pervasive crashes based on the impact on real users.

Firebase Cloud Messaging (Push Notification)​

Using FCM, you can notify a client app that data is available to sync. You can send notification messages to drive user re-engagement and retention. For use cases such as instant messaging, a message can transfer a payload of up to 4000 bytes to a client app.

Remote Config​

Firebase Remote Config is a cloud service that lets you change the behavior and appearance of your app without requiring users to download an app update. When using Remote Config, you create in-app default values that control the behavior and appearance of your app. Then, you can later use the Firebase console or the Remote Config backend APIs to override in-app default values for all app users or for segments of your user base. Your app controls when updates are applied, and it can frequently check for updates and apply them with a negligible impact on performance.

Gson​

The GSON JsonParser class can parse a JSON string or stream into a tree structure of Java objects. GSON also has two other parsers. The Gson JSON parser which can parse JSON into Java objects, and the JsonReader which can parse a JSON string or stream into tokens (a pull parser). This tutorial focuses on the JsonParser though - GSON's tree parser.

import com.google.gson.annotations.SerializedName

data class LoginRequest(
    @SerializedName("email") var email: String,
    @SerializedName("password") var password: String
)

Picasso​

Picasso is a powerful image downloading and caching library for Android

Glide​

Glide is a fast and efficient open source media management and image loading framework for Android that wraps media decoding, memory and disk caching, and resource pooling into a simple and easy to use interface.

Airbnb​

Paris lets you define and apply styles programmatically to Android views, including custom attributes.

  • Apply styles programmatically at any time.
  • Combine multiple styles together.
  • Create styles programmatically (as opposed to using XML).
  • Use annotations to easily support custom attributes (inspired by Barber).
  • Declare explicitly supported styles for your custom views.
  • And much more...

Square Up OK HTTP 3​

HTTP is the way modern applications network. It’s how we exchange data & media. Doing HTTP efficiently makes your stuff load faster and saves bandwidth.

OkHttp is an HTTP client that’s efficient by default:

  • HTTP/2 support allows all requests to the same host to share a socket.
  • Connection pooling reduces request latency (if HTTP/2 isn’t available).
  • Transparent GZIP shrinks download sizes.
  • Response caching avoids the network completely for repeat requests.

OkHttp perseveres when the network is troublesome: it will silently recover from common connection problems. If your service has multiple IP addresses, OkHttp will attempt alternate addresses if the first connect fails. This is necessary for IPv4+IPv6 and services hosted in redundant data centers. OkHttp supports modern TLS features (TLS 1.3, ALPN, certificate pinning). It can be configured to fall back for broad connectivity.

Shimmer Loading​

Shimmer is an Android library that provides an easy way to add a Shimmer effect to any view in your Android app. It is useful as an unobtrusive loading indicator that was originally developed for Facebook Home.

Circle Image View​

A fast Circular ImageView perfect for profile images. This is based on RoundedImageView from Vince Mi which itself is based on techniques recommended by Romain Guy.

DP Sizer​

DP Sizer is an android lib that provides a new size unit - sdp (scalable dp). This size unit scales with the screen size. It can help Android developers with supporting multiple screens.

SP Sizer​

SP Sizer is an android lib that provides a new size unit - ssp (scalable sp). This size unit scales with the screen size based on the sp size unit (for texts). It can help Android developers with supporting multiple screens.

AHBottomNavigation​

AHBottomNavigation is an library to implement the Bottom Navigation component from Material Design guidelines (minSdkVersion=14).

FragNav​

FragNav is an Android library for managing multiple stacks of fragments (e.g., Bottom Navigation , Navigation Drawer). This library does NOT include the UI for bottom tab bar layout. This library helps maintain order after pushing onto and popping from multiple stacks(tabs). It also helps with switching between desired tabs and clearing the stacks.

RXJava2​

RXJava2 is an library that lets you create applications in the reactive programming style. At its core, reactive programming provides a clean, efficient way of processing and reacting to streams of real-time data, including data with dynamic values.

Retrofit2​

Retrofit2 is an REST Client for Java and Android allowing to retrieve and upload JSON (or other structured data) via a REST based You can configure which converters are used for the data serialization, example GSON for JSON.

Pretty Logger​

A Pretty Logger object is used to log messages for a specific system or application component. Simple, pretty and powerful logger for android.

Logger.d("debug");
Logger.e("error");
Logger.w("warning");
Logger.v("verbose");
Logger.i("information");
Logger.wtf("What a Terrible Failure");
