If you are behind a proxy, create a gradle.properties file next to your build.gradle file with this :

systemProp.http.proxyHost=YOUR_PROXY systemProp.http.proxyPort=YOUR_PORT systemProp.http.proxyUser=USERNAME systemProp.http.proxyPassword=PASSWORD  systemProp.https.proxyHost=YOUR_PROXY systemProp.https.proxyPort=YOUR_PORT systemProp.https.proxyUser=USERNAME systemProp.https.proxyPassword=PASSWORD 

systemProp.http[s].proxyUser and systemProp.http[s].proxyPassword are not required if you don't need to login for your proxy. In such a case, remove these lines.

Make sure you have a internet connection.
If you have it , so maybe android studio couldn't download classes from Jcenter. So you have to force android studio to download classes from other resource like Maven.

To do that open gradle.build file and change the two jcenter() text with mavenCentral() ("C" in maven"C"entral() must be typed in uppercase) and try syncing with gradle again.

You don't need to do that every time you open your project. Just do this every time you create a new project in Android studio.

Solutions: 1. update your Build tools. 2. Reinstall sdk.

In my case, all the executable ".exe" files in "sdk\build-tools\25.0.3" folder were corrupted by virus. solution 2 worked for my perfectly. :)
