Installing Android SDK

Download the following files:

• Java SE development kit Jdk x86 / 32-bit only any version from here. (without Oracle account login)
• Android sdk from here.

First Install jdk which is required for the installation of Android sdk.

Then install Android sdk, If you get an error that "Java SE development kit not found" then follow the steps below,

• Press back and then Next again (works most of the times).
• If it still shows the same error then you may have to set the path, Just goto control panel > search for "advance system settings" > open it > click "Environment variables" there you may find a variable named "JAVA_HOME" select it and click edit, if you dont find it then click new, in the variable name type "JAVA_HOME" and in variable value give the Path of your jdk installed for eg. ("C:\Program Files(x86)\Java\jdk1.7.0_07"). be sure that u specify you own version of jdk, just go and check your folders. now Click OK > Click OK > Click OK then try installing android sdk.
• If you still get the same error, just check that the version of jdk you have installed and the version of Android sdk you are trying to install are both x86 / 32bit versions, if not then download again.

If you dont get any error while installing then you are doing just right.

After installing Android sdk open sdk manager form start, you will get a list of packages to install just select "android sdk platform-tools" and "google usb driver" unselect the rest, click install packages and let it install and you are done !!

Sdk manager will show you where are your platform-tools when you select it in the packages list, its is generally in the folder
 "C:\Users\[your PC name]\AppData\Local\Android\android-sdk\platform-tools" Appdata is a hidden folder so you may just type the address on your address bar to navigate to the folder.
