With such a variety of Android applications taking off high in the market, it may very well appear a piece of cake to the layman as to an Android application development. Making uncontrollably prevalent applications, the Flappy Bird, for example, is not a simple task. There is a tremendous measure of things to remember while making an android application, and to help you to come nearer to turning into an accomplishment in the field, we have assembled a rundown of fundamental rules that we trust you will need all the while.
Keep It Simple!
Most important factor to keep in mind is that an Android app development should be as simple as possible. The purpose of creating an app can be understood by all age group and not make it “rocket-science like” at all. It is very crucial to remember that you are developing an app to solve a problem and it should be easy to play around with which is again pivotal in keeping matter simple.
1. Several Platforms and Devices
Conventional desktop and laptop PCs are Windows-based with a standard screen size, components, and form factor. The mobile landscape is a great deal more divided, with four fundamental stages (Android, iOS, Windows Phone, and BlackBerry) that are consistently advancing. In like manner, building mobile applications needs more components to consider when arranging, including which gadget stage to assemble to start with, what versatile innovation choice to pick, what capacities ought to the mobile phone support, and the need for a long-haul guide with sending on additional, next platforms. Rather than customary Windows-based desktop development, versatile engineers need to consider making application code for different stages Android, Windows Phone, iPhone, and BlackBerry. Planning an application that is upgraded for different gadgets with various screen densities and screen sizes is much more difficult.
2. Screen size
Applications intended for a desktop or laptop customer work with a screen size that far surpasses that of mobile devices. The most effective method to outline for a gadget that fits in your pocket requires simplifications and a reevaluate about navigation. While a desktop application may have tabs, options, and connections on all sides of the screen and in accordance with content, for mobile you have to focus on the quick capacity, decreasing the number of choices to just those required for the prompt assignment or highlight.
3. User Interface
Rather than a mouse and keyboard, there is a very extraordinary mode for client input: touch. Indeed, even a solitary touch can include a variety of interaction, including single tap, double tap, long touch, move, and excursion. Every one of these activities must be captured. Desktop PCs and laptops give consoles to information passage, permitting agreeable, quick writing with both hands and all fingers. Since mobile phones don't have that capacity, even those with keyboards, manual information passage ought to be limited. Rather, wherever conceivable, give choices to choosing as opposed to requesting specifics through data entry. Not at all like clicking links with a mouse, tapping links using your fingers on a touch screen mobile phone is difficult. Clients can undoubtedly start a connection they didn't expect to tap and incidentally arrive on an undesired page. Bigger bars, tabs or buttons let clients tap with more accuracy.
4. Screen Density
Gadgets accessible from various producers fluctuate from 120 dpi for the lower-end HTC Tattoo/Wildfire and 240 dpi for the higher end Droid arrangement—a distinction of 100% in screen density. This implies using hard coded values for pixels and a solitary arrangement of pictures will prompt one of two things on a higher end phone: either your UI will be up-scaled and fluffy, or the controls will be too little to permit happy with focusing with a finger. Therefore, you have to package different resolution pictures and utilize display metrics to scale your custom drawing code.
5. Integration with phone functions
Smartphones are refined specialized gadgets. Making phone calls is their most fundamental capacity. While versatile stages put many constraints on outline and substance, they additionally open up new opportunities that conventional desktops can't give. For instance, reconciliation with telephone capacities, for example, coordinate calling and content informing gives clients a chance to choose a telephone number from a rundown, then call or content that number without typing it.
Another case: capacities, for example, GPS can be incorporated into location based administrations like mobile search. Numerous mobile devices can naturally recognize client nearness and give them nearby indexed lists, making effective open doors for organizations to advance their offerings in view of a man's vicinity to their place of business and their immediate intent.
6. Limited CPU/Memory/Battery Resources
Cell phones do not have the processing force and memory limit of most desktop and server frameworks. Designers need to compose calculations and perform code enhancement to bolster the mobile device limit. For instance, 1 GB of memory is an imperative in cell phones which is not found in today's desktop applications. That is not the same to the extent the phones go. Gadgets accessible from various manufacturers change from 120 dpi for the lower-end HTC Tattoo/Wildfire and 240 dpi for the higher end Droid arrangement—a distinction of 100% in screen thickness. This implies using hard coded values for pixels and a single set of pictures will prompt one of two things on a higher end phone: either your UI will be up-scaled and fluffy, or the controls will be too little to permitting happy with focusing with a finger. Along these lines, you have to package numerous determination pictures and utilize show measurements to scale your custom drawing code.
Another issue that desktop/web applications don't need to address is battery life. With desktop/web applications, you can have complex calculations running on the server because there are no battery imperatives. Be that as it may, in regards to mobile, a perplexing calculation or problematic code will deplete the battery rapidly. When outlining calculations, engineers need to consider battery utilization and plan for ideal use.
