Hi, i am trying to start react-native project in a real android device without installing Android-Studio in Ubuntu, getting the following error:

> react-native run-android
> Failed to find target with hash string 'android-26' in: /opt/android-sdk-linux/tools

I have also followed the below link to fix it up. But no luck.
