8個提高開發效率的Android庫

• Butter Knife
  One of the dependency injection based libraries. It’s used to avoid some of the annoying boilerplate code. It simplifies creating view dependencies and assigning several listeners to them ( like OnClickListener or OnCheckedChangeListener).
• Dagger 2
  I’m listing it under Square’s libraries, but they actually created the first version of this library. Now Google took over with its second iteration. It’s not yet considered stable, but many folks, including Google and me, use it on production already. It’s also a dependency injection library that lets us keep our object dependencies easy to access. It’s really fun to use, but it has a significant con: The learning curve for this library is ridiculously high.
• Retrofit
  The best library out there if you’re involved in creating rest services for your application. It also supports RxJava (which is a separate super awesome library).
• Hugo
  It’s a great tool for quick debug logging in android apps.

• Google Support Libraries
  It might be the obvious choice for most of the Android developers. Here comes all the fancy stuff that Google creates with a new version of their system and which their decide to make backward compatible. There are many modules to implement, depending on what you need. RecyclerView, CardView, transition animations, fragments, you name it.
• Materialish progress
  Simple and easy to use library for animating progress in material design style. I love it’s simplicity.
• RxAndroid
  It’s an Android implementation of original RxJava. It was implemented for Android by Jake Wharton from Square (yeah, again). It’s hard to say what is RxJava. It might be easier to say what is not. It’s material for a long talk. RxJava is a super powerful tool for threading and other stuff.  You should try to jump into it, but beware of it’s significant learning curve. This presentation from my collegue, Artur Glier, would be a great start to learn about it’s advantages.
• Switcher
  This one is created by me. After years of handling progress, errors and placeholders, me and my colleague Artur, came up with this clean solution. From the latest build it even allow to blur the view under your progress.
