Posted on Updated on

Smartphone users are constantly looking for new and exciting apps to enhance their mobile experience, thereby spurring growth of Android app development. The App Store today boasts of approximately 700,000+ apps with numbers growing constantly. It is possible to divide these applications into the following types.


  1. Foreground apps: Apps like map mash-ups and games fall into this category where their usefulness is limited to presence in the foreground of the screen. At other times, their activities remain suspended until required.
  2.  Intermittent apps: This variety of applications requires interactivity, but mostly their function is limited to backgrounds. The best example of this kind of apps is a Media Player. Both its installation and run is silent, whenever appropriate it will notify users to do the needful.
  3.  Background apps: Parts of Android app development, such software have limited interactions and apart from configuration remain hidden from view for most of its lifetime. SMS auto responders and call screening apps fall in this category.

Besides these, a number of other complex apps are associated with mobile devices; and it is difficult to categorize them under a single head. These combine features associated with the other three types of apps described above. An Android Developer considers their usefulness and designs them accordingly. What is the design considerations associated with each type of app for Android devices? Here are some of these for your consideration.

Developers need to consider the life-cycle of activity quite carefully when developing foreground apps to ensure its seamless switch between background and foreground. This is important because applications do not have any control over individual life-cycles, and any background app having no services becomes the prime cleanup candidate, by resource management of Android. For an Android developer, this means saving of application state when activity turns invisible, besides maintaining same state upon its return to foreground. Foreground apps need to present an intuitive and sleek user experience to make them attractive.

Background apps are silent workers that do not require much user input; and their function is primarily listening to actions or messages from hardware, system, and other apps. These do not rely much upon user interaction. Creation of invisible services is possible, yet availability of some user control is desirable in practice. Android App Development allows users to confirm running of services; they can configure, terminate, or pause the same when desired. This allows flexibility in design.

App creations reacting to user input may remain useful when not active in the foreground. These combine activity of visible controller with background invisible service. During user interaction, it is important for these apps to remain aware of the individual state. So,it updates activity UI when visible and in the background keeps sending notifications. This works for most users and is easy to handle. Discussing each business requirement is essential to get clarity before the app developments stages start. To learn more Visit Appster
