Step1.PreparingYourDevelopmentComputer

BeforegettingstartedwiththeAndroidSDK,takeamomenttoconfirmthatyourdevelopmentcomputermeetstheSystemRequirements.Inparticular,youmightneedtoinstalltheJDK,ifyoudon'

thaveitalready.

IfyouwillbedevelopinginEclipsewiththeAndroidDevelopmentTools（ADT）Plugin—therecommendedpathifyouarenewtoAndroid—makesurethatyouhaveasuitableversionofEclipseinstalledonyourcomputer（3.4ornewerisrecommended）.IfyouneedtoinstallEclipse,youcandownloaditfromthislocation:

//www.eclipse.org/downloads/

ForEclipse3.5ornewer,the"

EclipseClassic"

versionisrecommended.Otherwise,aJavaorRCPversionofEclipseisrecommended.

Step2.DownloadingtheSDKStarterPackage

TheSDKstarterpackageisnotafulldevelopmentenvironment—itincludesonlythecoreSDKTools,whichyoucanusetodownloadtherestoftheSDKcomponents（suchasthelatestAndroidplatform）.

Ifyouhaven'

talready,getthelatestversionoftheSDKstarterpackagefromtheSDKdownloadpage.

Ifyoudownloadeda.zipor.tgzpackage（insteadoftheSDKinstaller）,unpackittoasafelocationonyourmachine.Bydefault,theSDKfilesareunpackedintoadirectorynamedandroid-sdk-<

machine-platform>

.

IfyoudownloadedtheWindowsinstaller（.exefile）,runitnowanditwillcheckwhethertheproperJavaSEDevelopmentKit（JDK）isinstalled（installingit,ifnecessary）,theninstalltheSDKToolsintoadefaultlocation（whichyoucanmodify）.

MakeanoteofthenameandlocationoftheSDKdirectoryonyoursystem—youwillneedtorefertotheSDKdirectorylater,whensettinguptheADTpluginandwhenusingtheSDKtoolsfromcommandline.

Step4.AddingPlatformsandOtherComponents

ThelaststepinsettingupyourSDKisusingtheAndroidSDKandAVDManager（atoolincludedintheSDKstarterpackage）todownloadessentialSDKcomponentsintoyourdevelopmentenvironment.

TheSDKusesamodularstructurethatseparatesthemajorpartsoftheSDK—Androidplatformversions,add-ons,tools,samples,anddocumentation—intoasetofseparatelyinstallablecomponents.TheSDKstarterpackage,whichyou'

vealreadydownloaded,includesonlyasinglecomponent:
