View images transferred to Google Glass via USB

Question

Does anyone know if it's possible to transfer JPEG images to Glass via USB, and then view the images on Glass?

I tried copying the images on my PC and pasting to both the "DCIM" and "Pictures" folder under Glass' "USB storage" folder, but that didn't seem to work. I could see the images inside those two folders on my PC after the transfer was done, however, I just couldn't view them in my Glass.

Answer 1

This app allows you to browse all the media files in your DCIM/Camera directory http://html5webapp.blogspot.de/2014_04_01_archive.html

So download the zipped file, extract it, place the resulting .apk file in <sdk>/platform-tools/

Then on the command line (or terminal), go to the directory where the [application.apk] file is, and type the following commands while the Google glass is connected, and debug mode is on:

adb install [application.apk]

If you want to uninstall it later, type:

adb shell pm list packages

This will list the packages installed on your glass, look for the [package-name] that describes the app you installed and type:

adb uninstall [package-name]

Now wear the glasses, tap while in the card that shows the time, you'll get a list of applications that includes: "Media Gallery", it should include your new files.

Answer 2

I don't think that's possible now via standard Glass UI. You can write your own Gallery-like GDK app though.

From technical standpoint:

1. Cards in Glass Timeline are not simple pictures.
2. Seems like, Cards are populated via specific ContentProvider deep inside Glass. After you take a picture, another Card instance is created and inserted into Timeline. But this API is not available to anyone right now.
3. Technically, you can write your own Gallery-like GDK application, which would allow you to watch pictures available.

From Glass/UX standpoint

The idea of Timeline is that cards go to the past. From Glass Design:

Glass pushes older cards farther to the right where users rarely scroll and removes cards older than 7 days or when the 200 card limit is reached.
