cordova - Error while getting native targets for android: No valid Android SDK root found

Question

I'm trying to run the command:

ionic cordova run android

and this error always appears:

[ERROR] Error while getting native targets for android: No valid Android SDK root found.

This error occurred while using native-run. You can try running this command with --no-native-run, which will revert to using Cordova.

Environment:

Ionic:

   Ionic CLI                     : 6.12.3 (/usr/local/lib/node_modules/@ionic/cli)
   Ionic Framework               : @ionic/angular 4.0.1
   @angular-devkit/build-angular : 0.8.9
   @angular-devkit/schematics    : 0.8.9
   @angular/cli                  : 7.3.8
   @ionic/angular-toolkit        : 1.3.0

Cordova:

   Cordova CLI       : 7.1.0
   Cordova Platforms : android 9.0.0
   Cordova Plugins   : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 2.3.3, (and 13 other plugins)

Utility:

   cordova-res : 0.15.2
   native-run  : 1.3.0
