ADB in android studio

Question

I'm learning to use Android Studio. I've downloaded Android Studio Canary 4.1 from developer.android.com. When I started to run a template, I got this error (shown in pictures below). I hope someone can help me with this.

And this was shown in Help | Show log

First you shout sync successfully, in case you can`t sync successfully?

Follow this steps,

1. Download latest version of gradle .

2. gradle download link

3. After downloading it extract new folder.

4. Then open android studio. Go to file->settings->Build,Execution,Deployment->Gradle .

5. Then choose Use local gradle distribution and in the Gradle home give path of the folder where we have extracted file.

6. Finally restart your android studio.

Otherwise it will be occur from offline work in Global Gradle Settings , if its checked please UnCheck it. Have a nice day.
