Hi,

The following codes work fine locally.

It looks like this project is using the old java bindings rather that Foreign Code. Those bindings were deprecated a couple of releases ago and removed in the latest release.

Here’s the entry from the release notes:

Deprecation of Legacy Bindings

Before Foreign Code there was Bindings. The bindings were an attempt to bring Android and iOS functionality into Uno based on the best practices of the time. During the course of the implementation we found many shortcomings with those approaches and this eventually culminated in the creation of Foreign Code (see this medium article for the full story).

Foreign Code has since proved it’s worth, it handles all that our Legacy Bindings could and plenty more.

Since January we have put forward Foreign Code as the standard way of interacting with native APIs, and a couple of releases back we officially deprecated the legacy Bindings.

The next release of Fuse will not ship with the legacy Bindings.

While foreign code is the way to go these days we understand that there might still be codebases out there based on the Bindings. If this affects you then feel free to reach out to us, we are happy to offer advice on how you can refactor to foreign code.

I went through all the projects I could find on github using the legacy bindings and raised issues on them, sorry if I missed yours.
