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:
Solved! Reading the information on the page http://tools.android.com/tech-docs/new-build-system/license:
...
If you have accepted the license agreements on one workstation, but wish to build your projects on a different one, you can export your licenses by copying the accepted licenses folder from the Android Sdk Home folder
...
So I just went to C:\Android\sdk and copied the licenses folder to the C:\Android\android-sdk folder which was where Ionic was searching for the licenses.
Thanks to all who have somehow tried to help.
