Hi virtualmaster,
the code you’re asking about is Java code targeted for android SDK. MobiOne apps are HTML5 apps that work inside Apache Cordova environment. So, you have two options
a) try
phoneui.showURL(url, "_blank") / window.open(url, "_blank");
b) use our Viewer plugin to open an Intent registered for particular MIME type:
window.plugins.viewer.showFile(url, "MIME/type",
function(result) { /* ... */ },
function(error) { /* ... */ });
Please consult media player’s documentation which mime type you should use in order to hit it’s Intent.
