I get this error below when I try to build the ionic for android.
Command used: ionic cordova build android
Log error
Discovered saved plugin "WebViewer". Adding it to the project
Failed to restore plugin "WebViewer" from config.xml. You might need to try adding it again. Error: Failed to fetch plugin WebViewer@~0.0.1 via registry.
Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.
