Android Player

From MSX - Wiki
Jump to navigation Jump to search

It is possible to launch an external Android player (VLC, MX Player & Co.) via a system action (system:tvx:launch or system:tvx:launch:{APP_ID}) and to handle the results (e.g. the last video/audio position) via an application event (app:result). This API is available in Media Station X version 0.1.136 or higher for all Android and FireTV devices.

Property syntax of launch action data
Property Type Default Value Mandatory Since Version Description
id string null No 0.1.136

A custom request ID. This property must be set in order to trigger app:result events.

Note: Please note that an app:result event is also triggered if the application could not be launched (with result code 0).

uri string null No 0.1.136

The data URI. Typically, this property is set to a video/audio URL that should be played.

type string null No 0.1.136

The data mime type. Typically, this property is set to "video/*" or "audio/*".

component object null No 0.1.136

The component that should be launched. The object must conain a package property (of type string) and a class property (of type string). Typically, this property is not set, because the package is indicated in the action syntax (i.e. the {APP_ID} part) and the appropriate component is determined by the system.

extra object null No 0.1.136

The extra data handled by the launched application.

Note: Please note that some applications require special data types for the extra data. In such cases, you can use the type property to perform the required conversions.

Property syntax of result event data
Property Type Since Version Description
event string 0.1.136

Example[edit]

This example uses an interaction plugin to create the content and to handle the application events. Please have a look at this implementation script: https://msx.benzac.de/interaction/js/android.js.
