Advantages of Learning Android Programming in Java
Are you a tech-savvy person and do you love technologies? Are you the kind who loves to use android apps
and would love to move into the depth and details of the why’s of Android programming? 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.
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 a most popular programming language 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:-
1. Easy to learn and understand
2. Designed to be platform-independent and secure, using virtual machines.
3. Object-oriented
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, need 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 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 developer 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.
Hope you would have got the idea which I tried to convey in this blog post. Want to learn how to create hot
and cool Android apps using Android programming in Java? Then wait for my next blog and I will be back
with some more cool and new ideas.
