I am using ngx-translate plugin and when I run app on my Android device I got "HttpErrorResponse {headers: HttpHeaders, status: 0, statusText: “Unknown Error”, url: null, ok: false, …}"

P.S. on ionic lab translation is working. All files such as language JSON files exist in “assets/i18n”

Sounds like a version mismatch. Current version of @ngx-translate/whateverLoader uses different types then version installed a month ago. Would you share your @ngx-translate portion of the app.module.ts?
