Android Studio shows this kind of error
if you have moved the project from its defualt place or misplaced the gradle path.

so the simple answer is to replace the project to its defult place or change 
its gradle home path.

>Solution<

step 1) file>Setttings>appearance and behaviour>
system setttings>HTTP proxy> set No Proxy

step 2) build,execution and deployment> Build tools > gradle>
now under project level settings > select local gradle distribution>
gradle home = F:/Program Files/Android/Android Studio/gradle/gradle-2.4


NOTE: 
in my case my default android studio .gradle folder is located in
"F:/Program Files/Android/Android Studio/gradle/gradle-2.4"
change it with your defualt directory.
