Are you beginners in android application development? learning development from Android books? Looking for FREE android app source code to test and built sample application? you are at right place! here we have manually review and tested various android application source code and listed for your reference.

Android’s SDK (Software Development Kit) has been helping several developers, brands and organizations come up with unique apps and achieve high quality results and tremendous efficiency. The primary advantage of free android app source code (open source codes) is the high level of coordination and collaboration developers can achieve while developing new apps on android platform. The SDK inherently provides a wide variety of materials, including tutorials, extensive documentation, samples, best practices and a continuously growing array of tools. Open source software developers have always been motivated by several factors, but quality stands as the noticeable point of focus. If you are an AR or VR developers, you can also find various AR SDKs available in market to start with.

On internet you will find many mobile apps market place where developers can buy & sell their source code online and later re-skin the application based on requirements.

Android’s free open source community has always attracted highly motivated and bright professionals, who in-spite of being rather unpaid/underpaid, maintain the standards and discipline of the community. They have been the minds behind most complicated bug fixes and other enhancements that bring about a stark difference in the quality and usability of an app. For the individual developer, the community has been increasingly providing with source code that match new product features and design efficacy. Further, free and open source codes have the compelling advantage of pricing, apart from reducing the monotony of the job.

The popular reasons behind the growing use of free Android open source codes by developers includes:

  • Security: Free open source codes are highly scrutinized for their standards and a basic advantage is the high level of security you get. When a community of developers has accesses to lines of codes, there are more chances of any flaws to be detected, reported and addressed quickly. For free open source code developers, it is both money and credibility at stake and they give in their best.
  • Quality: Again, the higher standards put forward by the Android community ensures that only the highest quality of source codes is made available. However, it does depend on where you borrow your source codes from. If you have been following a reputed/popular platform (examples come later in this article), you are most likely at an advantageous position.
  • Customization: Customization is among the base reasons why app developers are looking for source codes. They don’t want to spend time of the basic scripting but focus more on the unique features and designs that they are supposed to develop. For example, the source codes for most ecommerce apps remain the same. It is the customization that allows the developer to come up with a completely new platform.
  • Cost: Most open source codes are available either for free or at a minimal price. For the source code developers, the number of downloads acts as a calculator in their portfolio, while end users of the source code can have the basic structure of their script readily available and at a minimal price.
  • Saves time: Finally, using free open source code saves a lot of time and allows you to focus all resources on the unique offerings of the apps. That’s the best way to stand against competition.
