error message you get is for cordova.  
if you upgrade your ionic native to v.3.x.x you will never get that error…  
if you still using ionic native v.2.x.x it’s normal for you to get that error message…

for your case now, try to run `ionic run android` command… and deploy your app to compatible device,  
if you still get build problem i guess it’s something to do with the plugin you are using now

You should really post your code as text and not as screenshots. Right now nobody can use Ctrl+F on your code, nobody can google your error message. If you want help, post your code and the error message and format it correctly so we can read it.

i’m sorry @sky_zt hehehe… i forgot the root cause…  
me and my boss actually get the same error like this 2 weeks ago…  
i suggest you to read this [https://github.com/driftyco/ionic-native/releases](https://github.com/driftyco/ionic-native/releases)  
on v.3.7.0 they say build error is fixed… i wish it will help your problem

Please edit your post and use the `</>` button above the post input field to format your code or error message or wrap it in ````` (“code fences”) manually. This will make sure your text is readable and if it recognizes the programming language it also automatically adds code syntax highlighting. Thanks.
