Answer 1

If you have Android Studio installed, try to copy the templates directory of Android Studio

C:\Program Files\Android\Android Studio\plugins\android\lib\templates 

to your android sdk tools directory:

C:\Android\sdk\tools 

This did the trick for me :)

Answer 2

I had a similar problem with Android Studio running on a Mac.

I fixed it with the following commands:

cp -r /Applications/Android\ Studio.app/Contents/plugins/android/lib/templates ~/Library/Android/sdk/tools chmod a+x ~/Library/Android/sdk/tools/templates/gradle/wrapper/gradlew
