I don’t know any specifics since I’ve never done this myself… But I’ve seen it work before, so you might get an idea of how to go about this and maybe figure it out or search on the web how to do it. Just hoping this helps
You can create a webview within your native application. In this native application you should be able to load your ionic application from local files (this is basically what cordova does as well). Your only problem is, you won’t have any acces to cordova specific features, you have to use the plain ionicframework since you are not using cordova in fact.
You should be able to use ionic in your webview like you would use ionic in your native browser though.
Not sure how to do this since I’m not really a native expert (yet?) and have never worked with custom webviews in native apps. Might be that you got an idea though
