Introduction to Maps Programming
Thebestindonesia.com – To make it easier for developers to add mapping capabilities to applications under development, Google provides a library for displaying maps, including the com.google. Android.maps package. Classes from the com.google. Android.maps package offers built-in downloading, rendering, and caching of map chunks, as well as various options for display and control.
The introductory class in the Maps package com.google.android.maps.MapView, a subclass of ViewGroup. A MapView displays a map with data obtained from the Google Maps service. When the map view has focus, it automatically captures button presses and touch gestures to pan and zoom the map, including network requests for additional map chunk handling.
It also provides all the UI elements a user needs to control the map. Developed applications can also use methods of the mapView class to programmatically control the map View and draw several different types of overlays over the map.
In general, the mapView class provides a wrapper for the Google Maps API that allows your application to manipulate Google Maps data via methods in a class and allows programmers to work with Map data as they would be selected in other types of Views.
Marker and Info window on Digital Map
Very often, however, a user may wish to add markers to the map to indicate places they feel are of interest to them, and this material will show how a user can do this on Android. This concept is referred to as a marker, which provides a sign or icon indicating a position like on a map for a specific location.
For markers besides small red balloon images, developers can also use other ideas, such as examples, to indicate the location of a store. Developers can use pictures that represent shops. Apart from that, to give the impression that the application being built is not just showing the location of a place, it is better if additional information is provided that is more attractive. This is referred to as an info window. An info window is a marker on a Google map that includes additional information by clicking on each marker that appears on the map with a small popup window containing information on the name of the place and its address. In the info window, the report doesn’t have to be names and addresses; other information can also be provided. First, create a png image containing a marker or other and copy it into the res/drawable folder in the project. For the best effect, the programmer should make the image background transparent so that it doesn’t block parts of the map when an image is added.
GPS Components On Digital Maps
1. Location
Displays the coordinates of a location using GPS technology and implements them into a digital map using Google Maps.
2. Track
Direction is a technique for displaying the path that must be taken by application users when going to a place with the help of a navigation system with digital maps.
The way to do this is to find the coordinates of the source where the user is located and detect the destination coordinates of the user, then use a class paint.setColor(Color.GREEN); then it will describe the direction (path) between the two places, here you can set the color for the order with the command. An example is a green (GREEN).

Web-Based Management System Design
The last few years have marked a significant framework boom, and almost everyone involved in web application development today is part of the new generation of ‘boomer frameworks’. Web development frameworks help applications developed to jump-start quickly and provide the core foundation needed to swiftly turn ideas written on a whiteboard into functional, production-ready code, with all the standard features expected of today’s web applications and the choice of frameworks available that life up to those expectations. Modern, flexible, and extensible frameworks are almost as important a tool as the programming language itself for today’s web developers. Moreover, when the two are complementary, the result is a very powerful toolkit: Java and Spring, Ruby and Rails, C# and .NET, and PHP and Yii. To run Yii web applications, all that is needed is the core framework files and a web server that supports PHP 5.1.0 or higher. To develop with Yii, you only need to know PHP and object-oriented programming (OOP). And there is no requirement to learn new configuration or template languages. Building Yii applications involves writing and maintaining its custom PHP classes, some of which will extend from the core Yii Framework component classes. Yii incorporates many great ideas and works from other well-known web programming frameworks and applications. So if a programmer comes to yii after using different web development frameworks, chances are the programmer will find it familiar and easy to navigate.
