For Beginners of Android app development, it is very important to understand first what is Android?
Introduction of Android
Android is an operating system which is based on Linux. It is primarily designed for touch screen devices such as Smartphone and tablet computers. Android works as an open source, its code released by Google under the Apache License. This enables Android to be freely modified and distributed by device manufacturers, wireless carriers and enthusiast developers.
Android has a large number of Android app developers who write its applications. In the beginning, it was written in a customized version of Java programming language. It is estimated that the number of applications downloaded from Google play, Androids prime app store, is approximately 25 billion.
Nowadays, Android has become the world's most widely used Smartphone platform. Due to its characteristics of being a low-cost, customizable and lightweight operating system for high tech devices, Android is now also used in televisions, gaming consoles, digital cameras and other electronics. Today, Android has a 75% share of the smartphone market with 500 million activated devices in total and 700,000 activations per day. Some of the Android stats are as follows:
Tips and Tricks for Beginners of Android App Development
Today, everyone is switching to Android and this invites a large community to start their careers as Android app developers. For the beginners, there are some basic tips and tricks for Android app development. These are:
• Knowledge of SQL: A beginner of Android app development should have knowledge of SQL. SQL is “Structured Query Language”. It is a special purpose programming language designed for data held in a relational database management system. Without the knowledge of SQL, a new developer will not be able to become an expert in Android app development. SQL helps Android to keep the data saved even the Android device stops working unexpectedly. The Android OS uses “SQLite”, therefore the knowledge of SQL will help a beginner to develop a stable app or game.
• Knowledge of Application Code: Android is a free source code operating system, so it is very important for beginners to have knowledge of ‘codes’. As a developer, a beginner will have to work on different projects with different requirements. There is a possibility that they will have to deal with large applications with different complexities which a beginner wouldn’t be able to handle; but, there is a solution around the corner. As a beginner, one can break the large application into small applications in a manageable way. Instead of a single large application, small applications will benefit in a way that they are easier to write, take less time to load and take a small amount of resources.
Knowledge of Programming Languages: A beginner for Android apps development must have knowledge of programming languages. The Android platform supports several programming languages like C, C++ and Java. Java is the most common programming language used for Android Apps Development; primarily Java was the programming language for Android. Java adds great features to your apps, too!
Knowledge of Useful Tools for Application: It is a fact that before downloading any app or games from play stores, users including me read comments regarding that app or game. If the comments are not good or unsatisfying, we don’t download that app or game. Therefore, it is important that while developing an app or game, a beginner should have proper knowledge of the tools available for Android app development. Color layout is very important as a dull layout may not be able to hold on to the users’ attention. It is very easy to create colorful layouts; beginners just need to learn XML language. Other tools to design Android apps are ADT plug-in, Eclipse and Android SDK.
Knowledge of Log Cat: It is very difficult to identify what went wrong with an Android app while it is in development. LogCat helps in debugging the app and provides the room to add a new perspective to the apps.
- Follow the Rules: Google has defined rules for android developers which a beginner should learn and follow to become a good Android app developer. These rules illustrate how new Android app developers can start, how they can end and how they can stop the application in between if they face failures. The best advice for beginners of Android app development is to meet some experienced developers who are serving in the industry.
Remember that practice make you perfect: I’d like to conclude by suggesting the beginners to follow the rules, tips and tricks defined above to become expert Android app developers. I repeat: practice makes you perfect! Happy Practicing.
