Palm webOS

Viewers and Players

The media applications can be used to play streaming or file-based audio or video content. You can use the Application Manager’s open method to handle common file types.

View File

There is no specific view file service; it’s just the general case of using the Application Manager’s open method, where the content target is unknown. As shown in the section Application Manager, simply call the Application Manager with a target value that refers to either web-based or file-based content:

this.controller.serviceRequest("palm://com.palm.applicationManager", {
     method: "open",
     parameters: {
          target: "http:// crypto.stanford.edu/DRM2002/darknet5.doc"
     },
     onFailure: this.onFailureHandler
});

Any supported file type will be passed to the appropriate application for viewing, editing, or other supported handling.

Audio

The Music player is used to play or stream a file or other web-based content encoded in any supported audio format. Launch the Music player with the Application Manager’s open method and a target property in the form rtsp://audio-file, where audio-file is a well-formed URI targeting a file encoded in a supported audio format. The target property can also point to a locally stored file, as shown in this example:

this.controller.serviceRequest("palm://com.palm.applicationManager", {
    method: "open",
    parameters: {
        target: "file:///media/internal/World.mp3"
    }
});

Refer to the Command and Resource Handler table in Appendix B, which has a complete list of all supported audio ...
