Could not find any matches for com.android.tools.build:gradle:2.3.+

Mirsa :

I'm getting this error in when I try to build my app through react-native run-android. It was fine yesterday, but suddenly get this error today. I try any solution but i'm still stuck.

I already check the react native vector icons and it looks fine, this also working well with iOS.

Here's the error

   * What went wrong:
A problem occurred configuring project ':react-native-vector-icons'.
> Could not resolve all files for configuration ':react-native-vector-icons:classpath'.
   > Could not find any matches for com.android.tools.build:gradle:2.3.+ as no versions of com.android.tools.build:gradle are available.

           details.useVersion "26.0.1"
        }
     }
  }

Base on this link

android licenses. Maybe try $ANDROID_HOME/tools/bin/sdkmanager "build-tools;26.0.1" "platforms;android-26" and see if that helps.

This Image can help you

I suggest you to update buildToolsVersion and supportLibVersion
