Instead of recover, I'd consider simply writing to the channel. https://play.golang.org/p/ShoadwrwTQ If it has to be a close, pass in additional state to close only once. https://play.golang.org/p/pwO3JF60Cr On Tue, Nov 7, 2017 at 3:32 AM roger peppe wrote: > On 7

Re: [go-nuts] A way to detect closed channel

meaning, don't call that select+code block from multiple goroutines. If on the other-hand that block is always called from the same goroutine, then it will do what you want, but that may be a slippery slope depending on what you're writing. On Mon, Nov 6, 2017 at 7:33 PM Dan Kortschak

Re: [go-nuts] Re: Pure Golang Android Service

The manifest can specify hooks for Service implementations, such as to start on-boot, but the platform still requires the implementation of the Service class. One could write a generic NativeService implementation for easy reuse and launching of native processes, but otherwise nothing has changed

Re: [go-nuts] Re: Gomobile and SAF

I'm inclined to say a Service would be better for Context access instead of a noop Activity. You should be able to make the Service instantiate needed resources or provide an implementation to instantiate those resources and a method for communicating that logic in Go. If you don't want parallel

Re: [go-nuts] Re: Gomobile and SAF

How were you intending to run the Go program? iirc you'll need access to a Context that can only be provided by the Dalvik VM, and that can only be instantiated via bytecode ran on the VM (so use Java). The first entry point this is provided is Application.onCreate when said class is declared in

As mentioned in last paragraph here: https://golang.org/pkg/runtime/ GOARCH, GOOS, and GOROOT are recorded at compile time and made available by constants or functions in this package, but they do not influence the execution of the run-time system. I'd first be inclined to think Mage source has

I haven't used these bindings but wouldn't you rename the v7 import as sapp "Java/android/support/v7/app" and then import "Java/android/app" then reference `app.AlertDialog` as appropriate? You'll also need to call `dialog.Show()` in `showDialog`. On Sat, Dec 24, 2016 at 8:35 AM glenford

The email was presumptuous, so as to describe "more productive", and threatening with "consider this a warning". It also felt cold and unwelcoming like a bot generated it. I do not advocate this CoC at all, but at the very least the email could have stuck to what was known to start a private

Yes, the Android app is a toy app. Touchscreen or not, the hardware latency alone makes that a fact. But that's why it's an example, not the root project. I've been using the gui example as a playground to work out further improvements to a separate project and I realize this is in disarray. I
