If your answer is a Yes, then you have landed at the right place. This blog will make you travel and explore the world of Android as to why Android programming should be done using Java programming language.
Why Learn Android Programming in Java?
Everyone has experienced the desire to program at one point or another. The hardest part of learning to program is to overcome the mental block. Learning to code is same as learning any language. In that case, have you ever wondered why to Learn Android Programming in Java??
Since we are talking about java here, first we need to have a brief introduction of what Java actually is? Java is one of the most popular programming languages which was developed by Sun Microsystems. It incorporates many of the powerful features of programming languages like C and C++ while also addressing some of their drawbacks.
Some of the important features of Java are:-[subscribelocker]
- Easy to learn and understand
- Designed to be platform-independent and secure, using virtual machines.
Android relies heavily on these Java fundamentals. The Android SDK (Software Development Kit) includes many standard Java libraries (data structure libraries, math libraries, graphics libraries, networking libraries and everything else you could want) as well as special Android libraries that will help you develop great Android applications.
Now the question arises as to why is Java easy to learn?
The answer is here. Java is easy to learn for a variety of reasons. Java is one of the most widely discussed, taught and used programming languages on the planet. It is one of the easiest languages to learn and its syntax is quite similar to that of C and C++. And last but not the least, Java is the most human-readable language among all the programming languages.
Another fact that needs to be discussed is that Android applications run in a special virtual machine called the Dalvik Virtual Machine(DVM). Let’s take this bubble idea a bit further. Because Java applications run under the assistance of a virtual machine, they have completely no connection with the inner hardware of the device. Therefore, a virtual machine can keep within itself and manage executing the code safely as compared to languages that operate in machine code directly.
The Android platform takes things a step further. Each Android application runs on the Linux-based operating system using a different user account. Android applications are closely checked and followed by the operating system and shut down, if there seems to be any problem with them i.e if they use too much processing power, do not respond properly, are not able to handle resources effectively. Therefore, it is important to develop applications that is highly stable and respond effectively. Applications can communicate with one another using well-defined protocols and code of communication.
Now, let us talk about the compilation of code and the role of Java in it. Java is a compiled language but its only drawback is that it doesn’t compile all the way down to the machine code. This means, you,who is the developer, needs to compile your Android projects or applications using Android and package them up to install and use onto devices.
Now let us discuss about one of the most important aspects of this topic. You may be aware of two different kinds of android applications, the Native app and the PhoneGap (Cross Mobile Application). Application that is created in such a way that it is designed to run on a single particular platform is called Native Application. On the other hand, Cross Mobile Application is an app that is created to run on multiple platforms of a smart device. Now we need to know that PhoneGap is a Cross Mobile Application. You may code once and use that on 6 different platforms / Mobile Operating Systems. Another important fact to know is that, Android is generally made to work with Native App.
Here, you may ask the question, WHY?
The answer lies in following line of discussion. Native Android Application works directly with Dalvik Virtual Machine which means that whatever codes you create, it would be directly compiled into the machine compiler code that can be understood by the[/subscribelocker] Java Machine to carry out tasks accordingly. The core language that is required behind the scene is Java.
Android Application Development is based on Java and uses Android Library packages. PhoneGap on the other hand, has a long procedure. The biggest advantage of it is that it does not require much knowledge of Java. PhoneGap has added certain specific tools that allow the developers to easily start working on the application without knowing the Java programming language. But the fact as always proved is that shortcuts are always dangerous. In this context, I mean to say that, PhoneGap comes with a number of disadvantages as well. Using this app prevents us from developing various interesting and useful applications which can be created using the Native App.
But here when we are talking about Android Programming, Native App which uses the Java programming language definitely has an upper hand in comparison to the PhoneGap. This is because Android doesn’t need to take the application as hybrid. The code just needs to be passed on to the virtual machine and the virtual machine carries the responsibility of finishing the task from there on. An example can make you understand it the best. The difference between the two apps can be seen by the difference in the time taken by them to complete the task. On one hand,where PhoneGap takes nearly 13 seconds to complete the task,on the other hand, Native Apps take just about 4 seconds for the same task. Hence overall, if you are going to make an enterprise level application or making an application based on the enterprise architecture with strong data structure handling and a lot of depth, then Native app is the best thing to rely upon and for Android programming, there cannot be a better alternative than Native App for this purpose.
