After almost a year of planning a.k.a. laziness, I am finally writing a post on the Android Studio Plugins that I use when starting with fresh Android installation.
I will be listing them and giving some quick intro. I hope this will help some and mainly I am trying to make sure that I don’t forget them and find the list easily. 
Mostly some of the Plugins mentioned below are for to make the android development faster and some are for lessen up the developer hassle.
.gitignore
I am sure by the name of this plugin we developers can know that it’s a plugin for ignoring files in Version Control. Here are some of its features that I pulled from the original site.
* Files syntax highlight
* Coloring ignored files in the Project View
* Show ignored files by specified ignore file (right click on .gitignore file)
* Hide ignored files in Project View
* Suggesting .gitignore file creation for new project
* Renaming entries from ignore file
* Close opened ignored files action
ADB Idea
Are you lazy enough to clean data, uninstall, restart app when you are developing/testing an app? This plugin makes an android developer life easy by making below actions easy:
* ADB Uninstall App
* ADB Kill App
* ADB Start App
* ADB Restart App
* ADB Clear App Data
* ADB Clear App Data and Restart
String Manipulation
It’s another lovely plugin which helps you when working with string and you wish to have some faster way of playing with Strings in Android Studio. It makes easy to toggle styles of Strings, Un/Escape, Encode/Decode, Increment/Decrement, Sort with natural order, Align and so many other stuffs.

Key Promoter
If you are a short-cut key guy *(or even if you are not)*, then you gonna love this plugin. It will help you setting up the keys and also will remind you the short-cut incase you didn’t use it. Sometimes you may feel annoying that it keeps reminding you, but trust me its for your own good & you will fall in love with this eventually 
Android ButterKnife Zelezny
If you are an Android Developer I am sure, you are using or must have used the Butterknife from Jake Wharton. So this plugin allows one-click creation of Butterknife view injections by creating ButterKnife injections from selected layout XMLs in activities/fragments/adapters.

Android Color Manager
While we can find lots of color related plugins, I am using this Color Manager plugin for my Android Studio. It helps you to do:
* See all color listed in Color Manager window
* Drag and drop where you want to copy the color name/tag
* Edit, Delete, Move, Search colors or colors name

Phewwww 
, I think & we all know, we can not include all the plugins in this single post, but these are the basic Andriod Studio Plugins, that I have been using to setup my Android Studio to be development ready. So guys, sorry if I have missed any of your favorite plugins, will try to write some more later.
I get by with a little help from my friends.
