Hi Dan, The gomobile reverse mode is very experimental, much more so than regular gomobile bindings. When in trouble, you'll probably have most luck going back to a working state and then add imports and usages of the reverse packages one at a time.
Also, while the reverse bindings can be useful to access Java/Android APIs easily from Go, I don't think it's realistic to use the reverse bindings to create an Androi app in (close to) 100% Go. The fundamental road block I found was keeping track of references between Java and Go, making sure no reference cycles persisted. And even if you succeeded, there's still iOS. I'm currently researching ways to create the UI natively in Go; I'm particularly interested in the way Flutter is designed. - elias On Monday, June 26, 2017 at 9:29:45 AM UTC+2, Dan Ballard wrote: > > So one thing slowing me down a bit is that there don't seem to be doc for > gobind reverse stuff, I'm just using AndroidStudio and the gobind gradle > plugin to call it.
