   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.

 109 ## Packagegroups
 110
 111 AGL DEMO Platform's
 112 [packagegroups](https://www.yoctoproject.org/docs/2.4.4/dev-manual/dev-manual.html#usingpoky-extend-customimage-customtasks)
 113 consist of the following:
 114
 115 ### packagegroup-agl-demo-platform
 116
 117 This packagegroup is used for generating the `agl-demo-platform` image,
 118 which is the full image for the AGL distributions IVI profile.
 119 You can see the recipe (i.e. `agl-demo-platform.bb`) that installs
 120 the `packagegroup-agl-demo-platform` packagegroup
 121 [here](https://git.automotivelinux.org/AGL/meta-agl-demo/tree/recipes-platform/images/agl-demo-platform.bb).
 122
 123 As meta-agl's design of packagegroups, the `agl-demo-platform.bb` recipe installs
 124 only `packagegroup-agl-demo-platform` and the packages of the DEMO applications.
 125
 126 ``agl-demo-platform`` contains the following four packagegroups:
 127
 128   * `packagegroup-agl-image-minimal`
 129   * `packagegroup-agl-image-ivi`
 130   * `packagegroup-agl-demo-platform`
 131
 132 ### packagegroup-agl-appfw*
 133
 134 These packagegroups contain packages for the AGL distribution's
 135 Application Framework.
 136 Subsystem should maintain `packagegroup-agl-appfw-[subsystem].bb`, which
 137 should hold sufficient packages for the Application Framework.
 138
 139 Subsystems also can maintain their own packagegroups using appropriate
 140 `recipes-*/`.
 141 For example, Qt5 has two packagegroups in `meta-agl-demo`:
 142 `packagegroup-agl-appfw-native-qt5` and `packagegroup-agl-demo-qt-examples`,
 143 which are under `recipes-qt/`.
 144
 145 The `packagegroup-agl-appfw-native-qt5` is included by
 146 `packagegroup-agl-appfw-native` because Qt5 belongs to native application
 147 framework of AGL Distro.
 148
 149 Because the `packagegroup-agl-demo-qt-examples` is not mandatory for
 150 the AGL Application Framework and the AGL DEMO, the packagegroup is added
 151 to the layer's `local.conf` file only when needed.
