Support Android

[leaanthony]

We'd like to support Android as a build target

Awesome!

We're hacking on a new project using Wails. Depending on success, we're aiming for an eventual Android release.

To know that it's feasible, I've hacked together enough code so the default Wails template can run on Android. I haven't integrated it into wails build, so it requires a manual build process: https://github.com/AlbinoDrought/wails-android-test (changes licensed CC-0, go wild)

Holy moley! This is amazing! Thanks so much - we will build on this post v2 release 🙏

what about ios target? fyne.io can do them all, let's have the main platforms(windows,linux,macos, android,ios) all with wails if feasible.

in that case, flutter could be the way to do? for android and ios that is

[ibonny]

Unfourtunately, in my experience, Dart gets complicated, and NativeScript has issues. For simplicity, there is nothing like the combination of a frontend web framework for UI, and Go for all backend work. This is why Wails is a really good winning combination. Dart is good, but it can get very complicated when trying to write stateful UIs. Bundling all this together in an APK for Android would be great.

I like wails and will wait for its android and ios support. in the meantime it seems flutter is the one most promising that covers the smartphone apps space.
looked into fyne before but I think wails desktop solution is better.

This would be absolutely amazing to have and would make wails my one-stop-shop for application development. Trying to use Flutter right now for android and boy howdy is it annoying.

Hoping this makes the cut for wails v2 at some point

wading into ios|android will be a very different and challenging task, you will have to call java-api or swift-api in the end to get all the juicy stuff from their ecosystems, golang will have to provide some bindings there, don't know how feasible this path will be.

https://github.com/socketsupply/socket uses some clever way(json marshalling) to work with android and ios webviews, maybe Wails can borrow some ideas there to get mobile supported. yes it will lack some native api features, but it might be good enough for 90% user cases.
