Create a Service in Android with Macroid using Contexts

[Javi Pacheco]

I'm trying to create several Views inside a Graphic Service with the SYSTEM_ALERT_WINDOW permission. I want to create view using getUi(...) but I need AppContext and ActivityContext implicit

I can't add "Contexts[Service]" in my Service. Is there some way for I can create views using macroid inside a service?

Thanks!

Hi,

For AppContext you can use

implicit lazy val appCtx = AppContext(getApplicationContext)

Unfortunately, Macroid does not support anything other than ActivityContext for creating GUI elements. So while it is theoretically possible to use the service’s context with that permission set, there is no way to construct an ActivityContext from it.

The short-term solutions would be either to create a temporary Activity and manipulate the GUI from there, or to use the native API. The long-term solution — I guess — is to create the notion of ServiceContext or somehow expand ActivityContext and overload w, l, dialog, etc, to support that. Feel free to file an issue demanding the latter approach :)

Yeah. I was working on ServicesContext[Service] with AppContext and a new ServiceContext implicit, but ActivityContext isn't possible inside a Service

For now, I have created a new utility in my project and I can create Option[W] from layouts easily, then I can use runUi() inside my views

Thanks Nick!
