...ont facing camera

Jira: https://jira.appcelerator.org/browse/TIMOB-15812

Issue was for devices like Nexus 7 (2012), code was trying to use rear facing camera which doesn't exists when overlay is being used.

var _window = Ti.UI.createWindow({
    backgroundColor:'white'
}); 
    var openCameraButton = Ti.UI.createButton({
        title : 'Open Camera'
    });

    openCameraButton.addEventListener('click', function(e) {
        var cameraOverlay = Ti.UI.createView();

        var takePhotoButton = Ti.UI.createButton({
            backgroundColor : '#fff',
            backgroundSelectedColor : '#efefef',
            borderColor : '#000',
            borderRadius : 17,
            borderWidth : 1,
            bottom : 65,
            color : '#000',
            height : 34,
            opacity : 0.4,
            title : 'Take Photo',
            width : '100dp'
        });

        var closeCameraButton = Ti.UI.createButton({
            backgroundColor : '#fff',
            backgroundSelectedColor : '#efefef',
            borderColor : '#000',
            borderRadius : 17,
            borderWidth : 1,
            bottom : 65,
            color : '#000',
            height : 34,
            opacity : 0.4,
            right : 10,
            title : 'Close Camera',
            top : 10,
            width : '150dp'
        });

        takePhotoButton.addEventListener('click', function(e) {
            Ti.Media.takePicture();
        });

        closeCameraButton.addEventListener('click', function(e) {
            alert('closing camera');
            Ti.Media.hideCamera();
        });

        cameraOverlay.add(takePhotoButton);
        cameraOverlay.add(closeCameraButton);

        Ti.Media.showCamera({
            success : function(e) {
                alert('success callback');
            },
            cancel : function() {
                Ti.API.info('cancel callback');
            },
            error : function(e) {
                Ti.API.info('error callback');
            },
            allowEditing : false,
            animated : false,
            autohide : false,
            mediaTypes : [Ti.Media.MEDIA_TYPE_PHOTO],
            overlay : cameraOverlay,
            saveToPhotoGallery : false,
            showControls : false
        });
    });

    _window.add(openCameraButton);

_window.open();

Please test this with devices with only front facing cameras. Eg Nexus 7 (2012).
