There are lots of options for taking screen shots and remotely viewing and controlling the glasses.
- If you press the power and volume - buttons at the same time, this will capture the display to a file in the Pictures/screenshot folder
- Another solution is Vysor, an App that works over USB or WiFi (you need the Pro version for WiFi) - see article below: https://developer.osterhoutgroup.com/hc/en-us/articles/115000135904-Mirroring-the-Glasses-Displays-on-a-Computer-using-Vysor
- Teamviewer is one of our partners, and their App Quick Support is on AppCenter. It allows a remote session on another host to view and control what's happening on glasses.
- Finally, a simple adb command:
- adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > screen.png
Android screencast works for screen capture; however it is a fairly low frame rate (4-5 fps max). It works over USB unless adb is shut off by security settings. Since Android Screencast is pretty old, Oracle Java 7 does not like how it behaves. For Android Screencast to work on a Mac, add this line of code to the exception site list in the java control panel.
Also, you cannot use Chrome as your default browser, since Chrome is not a 64 bit browser (yet). Instead, use either Safari or Firefox. Then, with some contorted fingers, you can take screen shots as seen in this example.
On Linux hosts, https://github.com/sankaryg/sji-android-screen-capture works pretty well. However, it is a bit more complicated to set up and has fewer more options.
