gomobile

问题 Can I access the phone's geolocation using a native gomobile application? I have seen experimental support for sensor data here, but nothing about the actual latitude, longitude of the device. I have no prior experience in app development, and I am learning Go at the moment. 回答1: AFAIK there is no ready solution yet to access location on both Android and iOS in a platform independent way. But in theory you could make separate packages using the gomobile tool to generate bindings for each

问题 Does anyone use gomobile app before and have successfully create files in phones? I tried the following code on Galaxy S4 with Android 4.4.2: package main import ( "golang.org/x/mobile/app" "golang.org/x/mobile/event/lifecycle" "golang.org/x/mobile/event/paint" "os" ) func main() { os.Create("zzz.txt") app.Main(func(a app.App) { for e := range a.Events() { switch e := a.Filter(e).(type) { case lifecycle.Event: _=e case paint.Event: a.Publish() } } }) } However no file is created in the phone.
