android - Eclipse dont show to ADT and SDK -

-

i confused eclipse problems. created project in android yesterday , today morning opened eclipse. saw there not option creating new android project. checked windows - > preference -> android , android option not available here , android sdk option not in eclipse.
import android project , see red color error on it.

i have installed both adt , sdk 

http://developer.android.com/sdk/installing/installing-adt.html

please me

there many possibilities query:

1) first of please check whether have installed correctly:

help --> install new software then

add link adt - http://dl-ssl.google.com/android/eclipse/

and read too

2) try window > customize perspective > command groups availability tab. check "android sdk , avd manager" option , hit ok button.

if "android sdk , avd manager" hasn't shown up, think there may kind of file miss match in eclipse.

3) if so, better start fresh: you can find step step guidance here
