1. Java as a prerequisite for
android development
Android os is an os which uses Linux system kernel, and it operates in
many portable devices such as tablets, and Mobile phones.
Google provided certification for android is very effective for non-android
designers who like to understand android but you must have some
primary knowledge in core Java.
Java is a genuine object oriented development terminology that can use
for complicated database integration. Android os program can create
in Java or C++ development language(NDK is required). Java is
extremely practical for newbies, Java is considered as a professional
terminology.

2. Programming Environment
An ideal Java atmosphere is very important to write Java program
code with ease and personal comfort. We suggest using the
Surpass IDE from the very beginning for all your Java as well as
Android os related development. Android os App Developers
must have development atmosphere i.e Surpass.
Data types form the simple and the main part of development
with Java. It’s essential to understand in great details about
almost all data kinds that come in useful in day-to- day
development. They include personality kind, int kind, drift kind,
boolean etc.

3. Basic Information types
Strings
This also id a significant aspect of
Java apps development.
Implementations of concatenation,
looking parts of sequence etc. are a
significant aspect of Java and confirm
on to be highly useful development

4. Methods
There are the most cases when similar
projects need to be carried out many
times within a program. Features or
techniques come useful here. You’ll use
thousands of functions when
development in any terminology hence
it’s crucial to become skilled at using
them. Some of the implementations of
functions might be to find the biggest

5. Qualifications:
1. Excellent understanding of the Android operating
system SDK
2. Information of XML and JSON a requirement
3. Information of SqlLite and a practical knowledge in
SQL databases
4. Information of HTML and Javascript a plus
5.Development requirements, business programming
abilities and good leaving comments methods is
important

6. Classes
In the actual life, you’ll find many
identical things of the same kind. Java
is basically an object-oriented
terminology, an element of it which
distinguishes it from many low-level
development different languages such
as C. Let’s take the example of a
motorcycle in the actual life. bikes
class objects of having two tires, a chair

7. Inheritance, Interfaces and Abstract Classes
Objects determine their connections with
the outside globe through the
techniques that they reveal. Techniques
make up the object’s interface with the
outside world; the control buttons on
the top side of your tv set, for example,
are the interface between you and the
electric cabling on the other side of its
nasty covering. You press the “power”
