Error trying to access Rho.Camera

Hi all,

We recently were asked to allow the MC40's and TC55's being used by our client to make pictures and send those. Expecting this to be a simple feature in Rho I started off but soon ran into problems.

This is the code:

function TakePicture() {
    try {
        var pCam = { desiredWidth: 768, desiredHeight: 1024 };
        Rho.Camera.take_picture(pCam, HandlePicture(e));
    } catch (err) {
        alert(err);
    }
}

function HandlePicture(params) {
    if (params["status"] == "ok") {
        Rho.Camera.saveImageToDeviceGallery(Rho.Application.expandDatabaseBlobFilePath(params["imageUri"]));
    }
}

Triggering the TakePicture() function returns the caught error: "TypeError: 'undefined' is not an object (evaluating 'Rho.Camera.take_picture')

The camera seems unavailable in the object:

The camera is under "capabilities" in the Build.yml.

Any suggestions would be very welcome, thanks in advance!

Hello

I'm experiencing the same problems as discussed here.
When I implement the tag below I get errors on the ORM.
   
gives:
    TypeError: 'undefined' is not an object (evaluating 'Rho.ORM.addModel')

I'm creating a SPA application using Angular JS so I have to include all javascript in the index.html.

When setting rho_javascript_api as the last script, I don't get ORM faults anymore. But I get different errors browsing trough the application. Some examples are:
     Error: 'undefined' is not an object (evaluating 'Rho.RhoConnectClient.isLoggedIn')
     Error: 'undefined' is not an object (evaluating 'Rho.Application.databaseFilePath')

When I don't use the rho_javascript_api everything works fine, but I really need the Camera to work!
Is there a sollution to fix this? Or do I have to wait untill the javascript API implements the Camera API for javascript?

As attachment my build.yml & index.html.

Hi Remco,
which rhoapi-modules.js are you using?

this file is generated from your build.yml configuration. By default it does not contains all the objects and can be platform specific.

Take a look at this documentation page:
http://docs.rhomobile.com/en/4.1.0/guide/webapps#connecting-with-your-w…

You can use the console command:

#platform may be: win32, wm, android, iphone, wp8
rake update_rho_modules_js[all]

Hi Pietro,

I used the rake you suggested, but the file is identical to the one I was using. I am using Rho 4.0 btw, not 4.1, not sure if this makes any difference.

The filesize is 267.680 bytes.

The Camera API is one that hasn't completed the move to the new 4.x RhoMobile API, instead you can 2.2 Javascript API for the Camera. Take a look at the Camera documentation for how to implement it specifically (a different JS lib required) Rhomobile | Camera API.
