The Android operating system has been extended to next generation mobile devices, add value to its functionality. You can easily program applications based on JAVA language.
This article started with a tutorial that will allow us to impact graphic design applications on these platforms.
Android is an operating system based on GNU / Linux originally designed for mobile devices, such as smartphones, but later expanded its development to support other devices such as tablets, MP3 players, netbooks, PCs, TVs, e-book readers and even, have come to see at CES, microwave and washing machines(W)
Development Environment
To create software that runs on devices with the Android operating system need a development environment. El SDK (Software Development Kit) Android can run on the Eclipse programming platform, which is necessary to complement ADT.
- In http://developer.android.com/sdk/index.html find el SDK for different platforms.
- And http://www.eclipse.org/downloads/moreinfo/jre.php the Java Runtime Environment you need JAVA development platform.
We can check if we have a version of the JRE installed from the command window with the following instruction:
java -version
First, install the JRE for, then, Install the Eclipse IDE:
in particular we use a version for JAVA developers
Downloading Eclipse allows us to obtain a compressed file. I unzip and get a directory with a set of files ready for use, namely, not need any installation.
Eclipse will start the application running the eclipse.exe file from the installation directory.
We can make a direct link to the executable to access directly from the desktop. This will facilitate subsequent access to the platform.
When you first start the program, will see a screen that identifies the version of the IDE (Integrated Development Environment) we're running.
An IDE is a programming environment q ue has been packaged as an application program, namely, is a code editor, a compiler, a debugger and builder graphic interface (GUI)(W)
The program will request a workspace (workspace) which is simply the directory in which to save ur projects. We can accept the default offered, or create a new one.
We turn the Welcome screen, from which to start the window system to develop the first program, or end Android settings.
Window system (also called Perspectives) will complete the installation and management in details the entire process of development of our programs. You should become familiar with this environment that allows high productivity.
Installing the Android SDK
After installing the Eclipse IDE, need the set of libraries for Android.
He can sign SDK is received as a compressed file and the auto-installing file. In the first case a folder descompress, in the second self-extract. Personally I prefer the first option, so as to control the entire process in detail.
Execute the application “SDK Manager” that will review the currently available packages.
We can accept that we suggest or choose “Accept All” to download and install everything that is available. Select this option may involve substantially increase the download and installation.
By accepting the installation, will download the selected items, both libraries and documentation.
The above procedure will update the SDK installation, creating new directories that contain different versions of development.
To complete the development environment we just add the Eclipse plug.
Installing the Eclipse ADT
which will open a new window to connect to the Eclipse software repository. We will give a name and address to complete the connection.
For example, can give the name “Android Tools” and use the address:
https://dl-ssl.google.com/android/eclipse/
We select “OK” to initiate the connection. Once, we provide the software available. We select “Developers Tools” and will press “Next” to continue.
We report the details of the installation and must select again “Next” to continue the license acceptance.
We must accept the license and click the button “Finish” to finish downloading
After accepting the license is downloaded and installed the files needed
Once downloaded and installed the software, you must restart Eclipse
The last step of the procedure consists in setting the TDA.
ADT plugin configuration
The configuration of the ADT is to indicate the installation path of the Android SDK. En el menú “Windows” The Eclipse, select “Preferences”
The installation directory will depend on the location you have chosen to unpack the Android SDK in the previous steps. Seek our specific direction and thus finalize the basic installation. In the tree view select right “Android” and option “Build” to open the dialog box that allows you to enter the path to the SDK.
This completes the installation and basic configuration. There are different parameters to customize the installation, which will be discussed later. Ya we can begin to plan for Android devices !!!
