[Oskari-user] Oskari RPC and Cordova Android app issue

[Mäkinen Sami (MML)]

Hi,

Apparently WebView sees the iframe as having a file:// protocol. This might be due to the iframe not being loaded yet and happens on browser as well, but JSChannel recovers from this. If the message ever reached the iframe with the file:// protocol you would might see this kind of message https://github.com/oskariorg/oskari-frontend/blob/master/bundles/framework/rpc/instance.js#L88. But if you can use just the iframe you could do the same things by running this kind of JS inside the map page:

    Oskari.getSandbox().postRequestByName('MapMoveRequest', [x, y, zoomlevel]);

This would by-pass the postMessage() and call Oskari API directly.

Hi,



just WebView for the iframe is ok.



In the browser that works fine. But when I try this in android phone with cordova "Osakari onReady" newer occurs.



try {
  channel = OskariRPC.connect(
    documentItem,
    mapAddr
  );
  channel.onReady(res => {
    this.loggerService.debugBuffer("Oskari onReady: " + res.clientSupported + " " + res.version);
  });



We are using https://hkp.maanmittauslaitos.fi maps.



This might be a reason maybe...but what can I do to allow this?:



Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (’https://hkp.maanmittauslaitos.fi') does not match the recipient window’s origin (‘file://’).“,

Hi,

Do you need the “parent page” or can you just do a WebView for the iframe src/the map? Most of the Google search results related to postMessage in WebView seems to deal with how to communicate between Java and Javascript by sending and receiving messages using the postMessage().

Hi,



does anybody have idea or knowledge how Oskari RPC could work with Cordova and Android Webview. With browser everything works fine but in Webview postmessages does not work for some reason.



For example:


this.channel.postRequest(
  'MapMoveRequest', [x, y, zoomlevel]
);​
does nothing.

I'm trying to convert www application to simple android app....the applications for herders. They take pictures and locations of dead reindeers... the location are shown in the map which is in iFrame.
