Answer 1

Try below steps -

1. Navigate to Home/User/Android/Sdk/build-tools.
2. Delete all the folders from there.
3. Go to SDK Manager and download the latest version of Android SDK build-tools.

Answer 2

This error "llvm-rs-cc" is missing : related to Android SDK "build-tools" folder, downloaded build tools will be inside this also in any build version folder like 28.0.3 there is a file with this name "llvm-rs-cc" if your android SDK path in not pointing to the right place and compiler couldn't find it this error will happen.

to Solve: 1- Change the Android Sdk path to the right location or 2- Delete related build folder inside "build-tools" (for example if in build.gradle : buildToolsVersion '28.0.3' you must delete the folder with the name of 28.0.3 ) and open "SDK Manager" and download related sdk. 3 - Change buildToolsVersion in gradle to another downloaded version
