The error :

```auto
.cache/GeneratedCode/main.g.uno(634,27): E3111: 'Fuse.Triggers.Actions' does not contain type or namespace 'Call'. Could you be missing a package reference?
.cache/GeneratedCode/main.g.uno(637,27): E3111: 'Fuse.Triggers.Actions' does not contain type or namespace 'LaunchEmail'. Could you be missing a package reference?
.cache/GeneratedCode/main.g.uno(640,27): E3111: 'Fuse.Triggers.Actions' does not contain type or namespace 'LaunchMaps'. Could you be missing a package reference?
`

```

The Command : fuse build --target=Android --run

The unoproj file

```auto
{
  "InternalsVisibleTo": [],
  "Packages": [
    "Fuse.Animations",
    "Fuse.BasicTheme",
    "Fuse.Controls",
    "Fuse.Designer",
    "Fuse.Drawing",
    "Fuse.Drawing.Primitives",
    "Fuse.Effects",
    "Fuse.Elements",
    "Fuse.Entities",
    "Fuse.Gestures",
    "Fuse.Desktop",
    "Fuse.iOS",
    "Fuse.Android",
    "Fuse.Navigation",
    "Fuse.Reactive",
    "Fuse.Shapes",
    "Fuse.UserEvents",
    "Fuse.Triggers",
    "FuseCore"
  ],
  "Projects": [],
  "Includes": [
    "*"
  ]
}

```

Everything works prefectly when I preview the app ( on android and local )

Tried everything, can’t figure out how to fix it

exept from removing the

```auto
<Call /> 
<LaunchEmail />
<LaunchMaps />

```

There must be a way, right ?

I am also running into this issue, getting the same error: `E3111: 'Fuse.Triggers.Actions' does not contain type or namespace 'LaunchEmail'` Using `Fuse version 0.9.8 (build 5700)` on `Windows 10`

Adding `Fuse.Launcher` to your `.unoproj` fixes this issue. Solution pointed out by jveres
