| Android Top 10 Important libraries which helps us to maintain the good code practices in general. |
Gson: Gson is a Java library that can be used to convert Java Objects into
their JSON representation. It can also be used to convert a JSON string to an
equivalent Java object. Gson can work with arbitrary Java objects including
pre-existing objects that you do not have source-code of.
Retrofit,
OkHTTP, Loopj: Retrofit is a type-safe REST client for
Android (or just Java) developed by Square. The library provides a powerful
framework for authenticating and interacting with APIs and sending network
requests with OkHttp.
OkHttp
is easy. Its request/response API is designed with fluent builders and immutability.
It supports both synchronous blocking calls and async calls with call-backs. Loopj is an Android
library for making asynchronous HTTP requests. I like it for its ease of
use and simplicity. Created by James Smith, it's also known as "Android
Asynchronous HTTP Client", and it's used by companies like Instagram, Pinterest,
and many others. It's a good entry point to the world of HTTP libraries, and
will help you understand important concepts very easily.
Otto:
Otto
is an event bus designed to decouple different parts of your application while
still allowing them to communicate efficiently.
Forked from Guava, Otto adds unique functionality to an already refined
event bus as well as specializing it to the Android platform.
Realm:
Realm is a mobile database and a
replacement for SQLite. Although is an OO database it has some differences with
other databases. Realm is not using SQLite as its engine. Instead it has own
C++ core and aims to provide a mobile-first alternative to SQLite. Realm store
data in a universal, table-based format by a C++ core. This is what allows
Realm to allow data access from multiple languages as well as a range of ad hoc
queries.
Universal
Image Loader, Picasso, Glide & Fresco: These libraries are powerful, flexible and
highly customizable instrument for image loading, caching and displaying. It
provides a lot of configuration options and good control over the image loading
and caching process.
Dagger2,
Butterknife: Dagger 2 analyses these dependencies
for you and generates code to help wire them together. While there are other
Java dependency injection frameworks, many of them suffered limitations in
relying on XML, required validating dependency issues at run-time, or incurred
performance penalties during start-up. Dagger 2 relies purely on using Java annotation processors and
compile-time checks to analyse and verify dependencies. It is one of the most
efficient dependency injection frameworks built to date. Butterknife,
Field and method binding for Android views which uses annotation processing to
generate boilerplate code for you.
LeakCanary: The
memory leak can be a headache to detect and to resolve, small memory leaks can
be hidden and may be seen after a long usage of the application and hunting
memory leaks is not a simple task.
Databinding
MVVM: Android offers support to write
declarative layouts using data binding. This minimizes the necessary code in
your application logic to connect to the user interface elements.
RxJava
& RxAndroid: This module adds the minimum classes to
RxJava that make writing reactive components in Android applications easy and
hassle-free. More specifically, it provides a Scheduler that
schedules on the main thread or any given Looper.
MPAndroidChart: Using these libraries,
drawing charts on Android could never be simpler. MPAndroidChart library
works on Android API 8 and above, but if you are using animations, it works on
API 11 and above. Animations is one of the greatest features apart from easy
data input, this library could have. Somehow I feel animations give good user
experience to an application. Through MPAndroidChart library, we can use more
than 25 inbuilt animations, also can define custom animations.
