10 Mistakes What Android Developers Do

From almost a decade android storm overtook the market with huge number of android lovers. But considering the recent progressions android app development is not as sweet as its name betokens.

In an era of beginning days there were fewer apps and limited development diameter of technologies used in it. Today there is massive growth and numerous other tech stuffs which are embraced that made app development bit knotty, besides that there are few very common mistakes which app developers nowadays do.

Here are top 10 mistakes which you should avoid if you are aspired to be a great app developer.

1. Not Evaluating Battery Consumption:

There are several other programs and functions too which consume android phone battery. Make sure that your app doesn't score top among them! Users are already woozy when it comes to android device battery back-ups, they wouldn't want to have an app that is hungry for battery.

Get down to bras tacks aforetime with memory consumption, and also affirm that the app refrains to process or doze when not in use. Know more about optimizing battery consumption.

2. Forgetting that there are Different Devices:

You are not making app only for your device! Believe it or no but there are more than 24,000 different android devices with different screen size, resolutions etc. Many app developers do not make it certain that their app is compatible for other devices too. This is in fact one of the biggest reason for app failure.

You can make your app adaptable for multiple devices by using density-independent pixels, XML, and other resources.

3. Heavy Bitmaps that Hinders the App:

Loading symbol for long time will wind somebody up, especially when it comes to customers they don't like slackened apps. Too many large images will eat up a lot memory and unfortunatelySmart phones usually do not have giant RAM that can support it and that results in prolonged loading.

Developers should focus on using the resources that will pile-up soon so that your app will be not curbed.

4. Complicated Layout.

Your app is not used by only touch perfectionists! The app should be developed keeping in mind that it is used by different kind of customers and needs to have near-perfect touch when visual feedback is considered.

Rookie customers should be always kept in mind who usually do touch mistakes. Know about StateListDrawablesfor your screen elements. The UI and the layout should be simple and easy to understand so that your app becomes everyone's cup of tea.

5. Too much Ingenious Ideas:

Creative ideas and designs are always loved, but in a dilemma of making it more creative if you design it in way that customers fail to understand the basic functions, it takes no time for your creativity to transform into a ludicrous stuff. Use familiar icons and symbols for various functions which are already embedded into user's mind. This avoids confusions and makes it easy to operate your app. Some of the examples are as follows

  • Triangle 'ᐅ': To play a media file
  • Cross 'X': To close a file
  • 2 Parallel lines 'II': To pause a running file
  • A house for home screen

6. Reinventing the wheel:

You might be great with codes and also might have went to profundity in android but do not do the venture of writing your own code that communicates with the server in the background thread without using the main thread.

Network calls, image loading, database access, JSON parsing, and social login are the most basic and common things which every app has. Smartness lies in going in the conventional way which is proven rational in this particular field. Some of the rational practices are listed below

  1. gradle as a build system.
  2. Retrofit / Volley for network calls.
  3. Picasso for image loading.
  4. Gson / Jackson for JSON parsing.
  5. common implementations for social login.
  6. Not using Fragments.

It is absolutely inefficient way to launch a separate activity for each app screen because the system will keep them in the memory for a long time. The resources needs to be freed for smooth operation timely but unfortunately even killing the activity also will not help to free the resources.

Android introduced a noteworthy article of fragments in the version of Honeycomb. Fragments can be of great use as they help developers to optimize different screens, can be managed by the parent activity easily and can also be reused, positioned and combined if need be.

8. Using multiple technologies:

Android is great and is good enough to be a standalone platform, there is no point in spoiling the soup with multiple cooks! Android is self reliant and have enough elements to make use of and there is no need to take ideas from other platforms.

Android lovers may not like an app that seems similar or identical to the one in an non-android device. Its uniqueness is its identity when it comes to UI design. Know more about the UI guidelines for Android app developers.

9. Not asking for help

App development field is something which renovates itself by every now and then. You might a good developer but sometimes you need to take help and upgrade yourself for better work progress. Nobody is going to steal your idea, more you associate more you will be benefitted.

Keep in touch with android developer’s community like Android development center where you can ask, discuss and get solutions for your questions. Android community is international and prevalent; you can refer to tags related to Android development.

10. Not having Confidence:

Rome was not built in a day! Important work takes time. If your first app couldn't bring any fruitful results than no issues, you can try again. Analyze with keen observations where you went wrong in previous project and overcome it. If you are confident, and eager to sharpen your skills with a will to develop an awesome app, may be not today but yes sooner you will develop one.

Keep your confidence up above all negative thoughts;Success is not too distant star.
