    Nice! Yeah, i've got some catching up to do obviously, but i'm sure it won't be that hard. Are you basically doing the whole make it autofocus thing?

    yeah....I am at the same point as Chet. I can get it to keep autofocusing but there is a pause between each one....so it's kinda like a strobe light.

    Interesting. Sounds like we'll have to wait and see what the December 11th update is going to include. Hopefully they'll toss in the torch and red eye modes.

    What mechanism are you using to get continuous auto-focusing? I have tried two.
  6. eclipsed4utoo

    with a while loop. inside of it, I do the autoFocus method.

    This is done in a background thread.

    I can get it down to about 1 second or a little less, but there's still that "off" period that makes it a strobe light.

    Also, if I don't show the Preview on the screen, the flash doesn't come on. Don't know how to get around that.

    autoFocus is only valid after startPreview() has been called. However, I have found that you can call stopPreview() immediately after startPreview(). You never see the preview and the flash still works. :)

    I am getting better results from putting an autoFocus call in the onAutoFocus callback.

    I had it there, but the "off" period was still pretty long. I was able to get the "off" period to be shorter with the background thread.

    awesome...so that part is fixed now. so I guess we are at the same point. Figuring out the "off" period between the flashes.

    hum... so how often are you calling autofocus in your background thread? infinite loop or a timer? I was running a timer before and was getting more off period. I believe the timer's run method is executed in its own thread.

    infinite until a button is clicked. the while loop checks a public variable for the class. if that variable is true, it continues to call the autoFocus(). so when the button is clicked, I just set that value to false, and it stops.

    DroidLight appears to have been removed for some reason.

    Is it simply a combination of the camera settings?
  19. Chet

    Chet Well-Known Member

    No. Nothing to do with the camera. This is the direct "turn it on" command we were looking for.

    Ok, so who would like to try it out? I am willing to email my test .apk if someone wants to test it. You will have to enable installing apps from "Unknown Sources".
