Android Player

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	The event type. For application result events, this is set to "app:result".
id	string	0.1.136	The request ID.
code	number	0.1.136	The result code. -2: Internal Error (MSX). -1: OK (System). 0: Canceled (System). 1: All codes of 1 or higher are application specific.
extra	object	0.1.136	The extra data returned by the launched application. Note: Please note that the properties of the extra data are converted to the appropriate JSON types (e.g. byte/short/int/long/float/double values are converted to numbers, URIs are converted to strings, etc.).

Example

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.
