force:navigateToURL

Relative and absolute URLs are supported. Relative URLs are relative to the Salesforce1 mobile browser app domain, and retain navigation history. External URLs open in a separate browser window.

Use relative URLs to navigate to different screens within your app. Use external URLs to allow the user to access a different site or app, where they can take actions that don’t need to be preserved in your app. To return to your app, the separate window that’s opened by an external URL must be closed when the user is finished with the other app. The new window has a separate history from your app, and this history is discarded when the window is closed. This also means that the user can’t click a Back button to go back to your app; the user must close the new window.

This example navigates a user to the opportunity page, /006/o, using a relative URL.

1gotoURL : function (component, event, helper) {
2    var urlEvent = $A.get("e.force:navigateToURL");
3    urlEvent.setParams({
4      "url": "/006/o"
5    });
6    urlEvent.fire();

4    var address = component.find("address").get("v.value");
