Whether you're first starting out developing an Android app or you're trying something different for your next app, it's never easy bringing all those nuts and bolts together to bring your vision to life. Some of the building blocks that can be used for creating an Android app are well known and easily accessible, but there are far more out there that you might not have even heard of. Open source projects all over the web can help bring your app together and help realize your vision, making sure that whatever it is you put into the Play Store will be of a decent standard.
App and game developers out there will know that no one man or one team can do everything on their own, which is why there's an excellent selection of simple libraries and utilities that can be pooled together to achieve things in your app or game. Android Arsenal is a new website that's sort of like a phonebook for budding developers or those looking for that last wrapper or library they need to bring it all together. With 273 links to projects all over the web, many of them listed on GitHub, and some of it info from Google themselves, Android Arsenal is an app developer's new best friend.
The list of links is steadily growing, as Android Police first reported the Arsenal having 254 links, so it's great to see that this is only going to go from strength-to-strength. This is perhaps something that will be of better use to an already established app developer, but newcomers will find some great libraries and tools that could save time and keep hair on their heads. Info linked to from Google themselves, such as info about AdMob would be good for smaller developers as well. Take a look at the site in the source link below and see what you can find.
