Appinfo.json

From WebOS101

Each application must have an appinfo.json file. This file contains information about your app that is used by webOS and the App Catalog.

Note: If you don't specify miniicon in appinfo.json, webOS will use a scaled black & white version of your app icon for notifications. If you want a color icon for notifications, specify miniicon (16x16).

Automatic Help Scene

As of webOS 1.3.1 you can include information in the appinfo.json file which will automatically generate a help scene for your app. The help scene is pushed via a call to pushAppSupportInfoScene. This is probably not supported in webOS 3.x, as the Mojo framework is deprecated.

Example help information:

"support": {
  "url": "http://support.mycompany.com",
  "email": {
    "address": "support@mycompany.com",
    "subject": "Support"
  },
  "phone": "555-555-5555",
  "resources": [
    {
      "type": "scene",
      "label": "Help Topics",
      "sceneName": "topics"
    },
    {
      "type": "web",
      "label": "Discussion Forums",
      "url": "http://forums.mycompany.com/"
    }
  ]
}

Example call:

this.controller.stageController.pushAppSupportInfoScene();
