How are you running PlayCanvas on Android? What system do you use?

Using Ionic framework(web view), I was taken android apk and It has been working successfully.

Yes, Ionic works great with PlayCanvas, it’s a great library. Then you should consult the Ionic API on how to write and read a file, that is responsible with interacting with the OS.

The PlayCanvas instance runs in a webview context and can’t do that.

I am using same scenario with iOS development. Can you suggest me. How to create and modify the text file in local storage? (It should be work both off-line and on-line mode). Is it possible?

Is Playcanvas having File System API?

Thanks in advance.

Ionic plugins I think work cross platform, so it will be the same. If that’s not the case that is something to discuss with their support or in their forums.
