1. Development Environments
   
   1. Android Studio - the blessed future of Android tooling. Gradle support baked in directly. Great live previews of views. Based on IntelliJ IDEA 13 CE
      
   2. Eclipse - Android is moving towards the Gradle build system and better tooling which is why it is listed first, but you could muck around with Eclipse (though Gradle support for it is nowhere near as far along as Android studio), and you can get Eclipse this way:
      
      • Get the SDK from developers.android.com and install.
        
      • It is probably easiest to get started using Eclipse and the ADT Plugin
        
2. Interested in creating low level native applications? Check out the Android NDK.
   

1. Forums member jkyuusai posts: Things I found useful while beginning Android
   
2. Android Design - Know and use Android design patterns. Don’t be a schmuck.
   
3. Android Training - Generally Android applications are created with Java and heavily rely on the Android framework which can take some time to learn. Google’s Android Training sessions are meant to catch seasoned Java developers up to speed and familiarize them with Android to get developers up to speed. Don’t miss any course listed under Basic Training, and really most of the Advanced Courses should be pretty well understood.
   
4. Vogella’s Android Development Tutorial - Lars Vogel is pretty well known in the Eclipse community and his series of Android tutorials have helped me from time to time
   
5. Professional Android 4 - The author of this, Reto Meier, is an Android DevRel for Google and this is a fairly comprehensive book on the Android APIs and essential developer knowledge.
   
6. If you’re interested in developing for Google TV there is Google TV specific development information available. Keep in mind TV is very different:
   

   Doctor w-rw-rw- posted:

   And while you might think you can just port your tablet layout to GoogleTV, remember that TVs don't have touchscreens, have up to 10% overscan on the edges, are navigated with the D-pad and not usually the mouse, and the option button is practically taboo.
   

   
   

1. Google Play - this is Android's major store. Allows staged rollouts and alpha/beta testing directly through the Google Play app on your end users device.
   
2. Amazon AppStore for Android - distribute here to make sure your apps can be installed on Kindle Fires and the like.
   
3. F-Droid - FOSS app store
   
4. Or just email the apk directly to your users, no provisioning necessary.
   

• Styling Android - Posts fairly frequently on different Android related topics, such as using vector drawables to help scale between different UIs and using Android components like the LruCache to create memory caches. (G+)
  
• Cyrl Mottier’s Android Development Blog - I mostly linked this because of the series of posts on ‘The making of Prixing’, this implementation of the sliding app menu (popularized by apps like Dolphin HD & Facebook) is pretty great.
  
• Holo Everywhere - this blog highlights/reviews Android apps and critiques their design. A good place for inspiration or direction on user expectation. (G+)
  
• AndroidDev Weekly - posts a couple of articles on Android development each week which vary in quality.
  
• CommonsWare Blog - wrote a book The Busy Coder's Guide to Android Development, posts an answer within 3s to any Android related question on StackOverflow.
  
• My Life With Android :-) - writes a few articles a month on various Android topics.
  
• Codependent - Chet Haase's blog. Chet is an Android framework engineer who is mostly responsible for making the animation libraries on Android no longer suck.
  
• Chris Bane's blog - Chris is an engineer on the Android developer relations team. He created the popular Android-PullToRefresh library.
  

• Web Requests
  
  • Ion - Library for handling web requests, including image downloads. Does fancy things like: supports animated GIFs (hard G) and deep image zoom.
    
  • OkHttp - Square's HTTP+SPDY client, probably use it with...
    
  • Retrofit - Square's type-safe REST client
    
  • Picasso - Square's image handling library. Very nice, easy to use API.
    
• Analytics
  
  • ACRA - a library enabling Android Application to automatically post their crash reports to a GoogleDoc form. Much more detailed information than Google Play gives you upon crashes.
    
  • Crashlytics - very nice crash reporting tool. Great iOS support too.
    
  • Google Analytics - kind of nice having app tracking sitting right next to web tracking tools
    
  • Flurry - Pretty popular. My shop has moved away from this tool but it's still widely used I think.
    
• Design Tools - creating assets for every major bucket is a pain, these can help
  
  • Android Asset Studio - generate icons and images at proper sizes given a source image, even has a 9 patch generator.
    
• Android Support Library - this is basically part of the SDK, but I mention it here because nearly every app will want to use something from the support library.
  
  • Gone are the days of ActionBarSherlock, if you're one of the unfortunate souls still supporting 2.x pull in the appcompat ActionBar from here.
    
  • Need a NavigationDrawer? The support library provides an idiomatic NavigationDrawer with instructions.
    
• Otto - A publish subscribe mechanism for Android. If you use this and IntelliJ I highly recommend the Otto IntelliJ plugin which will show you which parts of your application are publishing and subscribing to particular events.
  
• Dagger - Dependency injection with Guice/RoboJuice on Android is tremendously slow. Square made Dagger to be much faster (a lot of things are done at compile time, made possible by the explicitness of the object graph). Check out Jesse Wilson's InfoQ presentation on Dagger.
  
• Android SDK Reference Search - a Chrome extension to add ‘ad’ command to the Chrome omnibox which allows for searching Android Documentation, with autocomplete functionality.
  
• Timber - Jake Wharton's excellent logging library.
  
• Nine Old Androids - Backports the Android 3.0 animation framework to Android 1.0.
  
• Drag-Sort-ListView - Pretty neat looking implementation of draggable ListView items
  
• Crouton - A library based on Cyril Mottier's Activity tied notifications. Basically a better looking, more sensible, Toasts replacement.
  
• Android Priority Jobqueue - Async tasks are kind of a pain. Jobs are a bit nicer to deal with, especially when used in conjunction with a pub/sub mechanism (Otto/Green Robot), or maybe RxJava
  
• DevDrawer - excellent app for organizing your projects on your Android device. Create a widget that lists all of your applications (based on filtering package names), quickly delete apps or clear their data, have them available on your homescreen between installs without having to drag them from the app drawer.
  

• Awful for Android - developed by Ferg/Geekner/other contributors (thread here), a good example of an ActionBarSherlock application with tablet functionality.
  
• Markers - Pretty great drawing application with some neat customizations.
