I\'m trying to run my Ionic 3 project on my Android device with ionic cordova run android --device --stacktrace, but, I\'ve the following output:
ionic cordova run android --device --stacktrace
@Paresh Gami's answer helped resolve mine. Just a side note for Mac OSX user..
the full path is /Users/useraccount/Library/Android/sdk/tools/bin/
where useraccount is your current system user.
