Android, is one of the operating system being used in some mobile devices and have started meramah tablet gadget, ketenaranya makes a lot of people want to learn to develop android applications, on homemade tutorial this time I will share a bit about how to install android in eclipse so that you can develop a program based on your own android creations.

previously may have many similar tutorial in some blogs and forums, but my goal here is to share new knowledge that I got to be more useful and beneficial to others, therefore if there are any words or anywhere else, please provide your comments on this post.

Let us start, to start making an android-based applications you should prepare some applications first i.e., Android SDK, JDK (java web developent kit) and Eclipse version 3.4 or recommended using 3.5 (Galileo)

to android SDK can be downloaded at:
http://dl.google.com/android/androidsdk_r07-windows.zip
for eclipse can be downloaded at:
http://www.eclipse.org/downloads.
for JDK can be downloaded at:
http://java.sun.com/javase/downloads/index.jsp.

After all the application obtained the first step is to install the JDK, for installing the JDK as well as with the installing applications in General.

then you mengekstraks the android SDK, android SDK .zip is used to download some tools to create a complete development environment for android like the android platform, Google APIs, and so on, following the completion of the android SDK to be broken up, lay in a particular directory e.g. c:\program file\android-sdk-windows.yang you need to pay attention to is the directory where you saved the android SDK is because this directory will be used later to reference when we want to go back to that directory
then after that install eclipse, as well as with the android SDK, uninstalled it almost the same as the installation of the program in General following the JDK, SDK, android and eclipse installed on your computer then the next step is to install the ADT for eclipse.

Steps:
1. open eclipse. click help > install New software
2. in the open dialog avaliable software click Add
3. in the add site dialog enter the following address https://dlssl.google.com/android/eclipse/   click Ok and wait pending completion.
4. return to Avaliable software view, you can now see
"Developer Tools" on the list. Mark checkbox on developer tools
and click next.
5. in the Install Details dialog that appears, the android DDMS and Android development
tools featured are supposed to be registered, click I accept. to approve
license agreement and click finish
6. wait until the process of fetching complete and restart eclipse
NB: If there is a problem at step 3 change https to http, if the above process can't you can manually download ADT at developer.android.com

After you finish installing ADT, your next step is to add the Android platform, the steps:

1. open the android SDK and AVD manager (click the Android SDK on the android SDk directory you saved earlier)
2. on the plaform SDK avaliable package check android 2.2 API8
3. click Install selected to download and install.

at the very least to be able to develop an android application, you must have a single Platform with the version you choose, in our example this time aya installs platform for android 2.2, or froyo, NB: actually, you can select all of the platforms and tools supporting development of android applications that anywhere else but unduhnya process will take quite a long time.

After you successfully add the android platform, the final step is to create an AVD, to make it the steps are as follows:
1. open eclipse, select window > preferences.
2. Enter the path where you put the android SDK that you ekstraks last
3. in the window ecpilse > android SDK pili and AVD manager.
4. Select virtual devices in the left pane.
5. Click new, the create new AVD dialog will appear.
6. type the name of the AVD, e.g. "android 2.2"
7. choose a platform that has you added earlier (e.g. android version 2.2)
8. you can clear the field for another and finally click create AVD.

Useful as an emulator android AVD, AVD (android Vidtual Device) will run the application that you develop in eclipse.

well after everything is complete now you are ready to create your own android applications to create a new project then his pace
1. open eclipse select file > > new Project
2. Select the android project and click next
3. fill in the field-filed:
project name: hello android
application name: hello android
Package name: com.example.hellooandroid (or it's up to you)
createActivity: helloworld
4. check the version of the platform on the Build Target for example: android 2.2
5. click finish

to make android applications, at a minimum you should be using a java and xml, many tutorials to get started learn android programming

Thus tutorial this time may be useful to readers. thank you.
