How to Create an Android Application
Object-oriented programming (OOP) is a design philosophy that represents the idea of objects. Objects have data fields that are nothing actually, but the description of all these objects and all the activities done by the items are known as procedures.
By way of instance, you can say phone is a thing which has attributes like the name of manufacturer of this phone, the version number of the phone, price of the telephone, etc. The telephone's actions are defined in a procedure like the process to make calls with your phone, the process to utilize the Internet using your telephone, and these matters.
Java is a programming language that strongly implements OOP idea. Java is the most widely used programming language. android application Android OS is also developed using Java, so understanding about Java is obviously an advantage if you want to come up with a program for Android.
Have practical experience using Eclipse IDE for Java programmers. Eclipse IDE is an integrated development environment, one that recognizes different keywords and attributes of the Java programming language.
Acquire an Android cellphone. Obviously, having an Android cellphone handy can help you become mindful of Android features and capacities.

Minimum Required SDK is your lowest Android variant your application is going to support.
Target SDK is your greatest Android version your application will support. Always attempt using the most recent Android SDK version to support a larger number of Android apparatus.
Compile With is your stage model against which you may compile your application. Always ensure that this version should fit your Target SDK.
