Android Setting Default Camera for Video Capture

tl; dr How can I select the front facing camera and disallow changing to the rear facing camera?

I'm trying to write a simple app that will record video on an Android table. I've successfully done so, however I need to make sure that the front facing camera is used and to disallow switching of cameras using the built in controls.

My code is based on the kitchen sink application, I will provide it as a reference. Thank you so much for your help and consideration!

var win = Titanium.UI.createWindow({
    title: 'Video Recording from Appcelerator Titanium',
    backgroundColor: '#fff'
});
var recordButton = Titanium.UI.createButton({
    top: 10, left: 10, right: 10, height: 35, title: 'Record Video'
});
win.add(recordButton);
var shareButton = Titanium.UI.createButton({
    top: 50, left: 10, right: 10, height: 35,
    title: 'Share Recorded Video', visible: false
});
win.add(shareButton);
var saveButton = Titanium.UI.createButton({
    top: 100, left: 10, right: 10, height: 35,
    title: 'Save Recorded Video', visible: false
});
win.add(saveButton);
win.open();
 
/**
* We'll use the following variable to keep track of the result of our recording action.
*/
var videoUri = null;
 
/**
* When they click this, we'll start the video capture activity and wait to hear back from it.
*/
recordButton.addEventListener('click', function() {
    // http://developer.android.com/reference/android/provider/MediaStore.html
    var intent = Titanium.Android.createIntent({ action: 'android.media.action.VIDEO_CAPTURE' });
    Titanium.Android.currentActivity.startActivityForResult(intent, function(e) {
        alert(e);
        if (e.error) {
            Ti.UI.createNotification({
                duration: Ti.UI.NOTIFICATION_DURATION_LONG,
                message: 'Error: ' + e.error
            }).show();
        } else {
            if (e.resultCode === Titanium.Android.RESULT_OK) {
                videoUri = e.intent.data;
                Ti.UI.createNotification({
                    duration: Ti.UI.NOTIFICATION_DURATION_LONG,
                    message: 'Video captured; now share or save it!'
                }).show();
                // note that this isn't a physical file! it's a URI in to the MediaStore.
                shareButton.visible = true;
                saveButton.visible = true;
            } else {
                Ti.UI.createNotification({
                    duration: Ti.UI.NOTIFICATION_DURATION_LONG,
                    message: 'Canceled/Error? Result code: ' + e.resultCode
                }).show();
            }
        }
    });
});
 
/**
* When they click this, we'll start an activity with an intent chooser to let the user
* choose how they want to share their video.
*/
shareButton.addEventListener('click', function() {
    var intent = Titanium.Android.createIntent({
        action: Titanium.Android.ACTION_SEND,
        type: 'application/octet-stream'
    });
    intent.putExtraUri(Titanium.Android.EXTRA_STREAM, videoUri);
    Titanium.Android.currentActivity.startActivity(
            Titanium.Android.createIntentChooser(intent, 'Send Video via'));
});
 
/**
* When they click this, we'll save the video to the SDCard and tell the user where to find it.
*/
saveButton.addEventListener('click', function() {
    var source = Ti.Filesystem.getFile(videoUri);
    var target = Ti.Filesystem.getFile('appdata://sample.3gp');
    // note: source.exists() will return false, because this is a URI into the MediaStore.
    // BUT we can still call "copy" to save the data to an actual file
    source.copy(target.nativePath);
 
    Ti.UI.createNotification({
        duration: Ti.UI.NOTIFICATION_DURATION_LONG,
        message: 'Saved to: ' + target.nativePath
    }).show();
});

I've tried following http://docs.appcelerator.com/titanium/2.1/index.html#!/api/Titanium.Media-method-showCamera however there is no documented way to stop the recording. It doesn't appear as though there is access to a method similar to Ti.Media.hideCamera() or other similar method. Any thoughts?

have you tried calling the finish() method on the activity you have created above?
