Pictures saved with Camera API not visible to user

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Load Camera API Sample from ApiDemos
2. Call takePicture(null, null, mPicture);
3. Save picture to DCIM\Test in onPictureTaken
4. Plug in Glass and browse to location, picture & folder are not visible
5. Turn Glass off & on again (aka "the solution to every problem")
6. Plug in Glass and browse to location, picture & folder are visible now

What is the expected output? What do you see instead?
I expected the image to be visible to the user immediately after being saved in 
onPictureTaken. Instead, the user must power Glass off & on again before they 
can download the saved images. The stock camera app images are visible 
immediately after being taken however.

What version of the product are you using? On what operating system?
GLASS v1 (not yet swapped), XE12, GDK v2

Hello,

Have you tried following the steps provided in the CameraManager class:
  https://developers.google.com/glass/develop/gdk/reference/com/google/android/glass/media/CameraManager

This explains how you can use an ACTION_IMAGE_CAPTURE intent to capture an 
image with Glass.

Best,
Alain

Yes, taking a picture by launching the intent works, but it isn't what I need. 
I am building an app that needs to be hands-free and take a burst of images. 
The camera intent requires the user to tap to accept each image.

Hi,
Did you manage to take a burst of images without the previewwith the GDK ?

I also can't "tap to accept" my camera intent, OnActivtyResult doesn't not get 
called

this might be related to the behaviour whereby taking a picture with the Camera 
Intent will NOT yield a written file observable by a FileObserver the first 
time, while subsequent attempts will be observable by a FileObserver.

I ran into the same issue. Here is a solution (only a bit over a year late). 
After saving the new picture, call the following method and give the second 
parameter the filename of the picture: 

public static void scanFile(Context context, String filename)
{
    context.getApplicationContext().sendBroadcast(
            new Intent("android.intent.action.MEDIA_SCANNER_SCAN_FILE",
            Uri.fromFile(new File(filename))));
}
