   1 ## Introduction
   2
   3 The `meta-agl-demo` layer is the reference user interface layer for the DEMO
   4 platform of Automotive Grade Linux (AGL).
   5 The layer provides a reference platform and applications.
   6 The BitBake target name for the DEMO platform is `agl-demo-platform`, which is
   7 the full DEMO platform image.

 117 ## Packagegroups
 118
 119 AGL DEMO Platform's
 120 [packagegroups](https://www.yoctoproject.org/docs/2.4.4/dev-manual/dev-manual.html#usingpoky-extend-customimage-customtasks)
 121 consist of the following:
 122
 123 ### packagegroup-agl-demo-platform
 124
 125 This packagegroup is used for generating the `agl-demo-platform` image,
 126 which is the full image for the AGL distributions IVI profile.
 127 You can see the recipe (i.e. `agl-demo-platform.bb`) that installs
 128 the `packagegroup-agl-demo-platform` packagegroup
 129 [here](https://git.automotivelinux.org/AGL/meta-agl-demo/tree/recipes-platform/images/agl-demo-platform.bb).
 130
 131 As meta-agl's design of packagegroups, the `agl-demo-platform.bb` recipe installs
 132 only `packagegroup-agl-demo-platform` and the packages of the DEMO applications.
 133
 134 ``agl-demo-platform`` contains the following three packagegroups:
 135
 136   * `packagegroup-agl-image-minimal`
 137   * `packagegroup-agl-image-ivi`
 138   * `packagegroup-agl-demo-platform`
 139
 140 ### packagegroup-agl-appfw*
 141
 142 These packagegroups contain packages for the AGL distribution's
 143 Application Framework.
 144 Subsystem should maintain `packagegroup-agl-appfw-[subsystem].bb`, which
 145 should hold sufficient packages for the Application Framework.
 146
 147 Subsystems also can maintain their own packagegroups using appropriate
 148 `recipes-*/`.
 149 For example, Qt5 has two packagegroups in `meta-agl-demo`:
 150 `packagegroup-agl-appfw-native-qt5` and `packagegroup-agl-demo-qt-examples`,
 151 which are under `recipes-qt/`.
 152
 153 The `packagegroup-agl-appfw-native-qt5` is included by
 154 `packagegroup-agl-appfw-native` because Qt5 belongs to native application
 155 framework of AGL Distro.
 156
 157 Because the `packagegroup-agl-demo-qt-examples` is not mandatory for
 158 the AGL Application Framework and the AGL DEMO, the packagegroup is added
 159 to the layer's `local.conf` file only when needed.
