that can be taken care of with the silent audio.

yes, it is sounding once, right before the camera announcement.

I have an Android 2.3.5 device

- Apps like Llama can't kill CamerAlert on later Android devices. It would be good if CamerAlert could kill itself (exit) when I left my car - (on battery power AND no headphone lead plugged in AND selected Bluetooth device disconnected) This would make it one less app I have to close as part of my 'navigation' solution every time I leave the car. Actually, even a widget to toggle turning CamerAlert on/off would be easier than having to enter the app to disable it...

- An explanation of what the settings Direction Difference, Warning Cone and Warning Sensitivity actually do. Their descriptions are a little confusing/similar (to me) so with 3 of them I'm not sure what I'm adjusting. Maybe some diagrams in a FAQ (showing angles/examples) would help a lot :-)

Llama needs to attack the CamerAlert service, not the activity. Their problem, not ours.

The settings are explained in the screen where they can be changed. Generally you want to keep them at the middle position. Can you give an example of what you find confusing? I'll leave it up to the artists in the team (or MaFt) to come up with nice diagrams.

:: Llama needs to attack the CamerAlert service, not the activity. Their problem, not ours.

Fair comment, though I think it's got to do with what APIs are available to apps on an unrooted handset - but I'm no expert. Either way, I think a widget to toggle the CamerAlert on/off would be a useful usability enhancement, if only for those who didn't want yet another app to control CamerAlert. DriveSafe.ly takes this approach, for what it's worth. Smile

:: Can you give an example of what you find confusing?

What's the differences between angle of

- Direction difference: my heading and the camera heading (how does the camera have a heading if it's not moving?) vs.

- Warning cone: my heading and the bearing to the camera

and

- Warning sensitivity: product of distance to camera and bearing to camera

I think this boils down to my lack of understanding of what these angles are if I was to look from above...

Let's assume we know the difference between heading and bearing

heading: direction you are moving towards
bearing: where the stuff is that you are interested in, not necessarily the same as the heading (especially prominent with boats and planes that have to fight cross winds etc)

When we say camera heading we mean the direction of travel that you need to have to trigger the camera. So if you drive due south, the camera heading would be 180.

Direction difference: when you travel direction 45, and the camera points to 120, it is rather unlkely that the camera triggers when you pass it.

Warning cone: Even though you travel direction 45, and the camera has heading 45, your bearing to the camera is too far out from your route (in a straight line). Most likely the camera is on a parallel road.

Warning sensitivity: a formula that mixes the above together to try and judge how likely you would be reaching a particular camera any time soon, giving your speed and direction of travel relative to the camera position.

Can CA be made to detect when GPS has been manually disabled and shut down? If I disable GPS, CA just continues to run but, if I recall correctly, DOES shut down after a period of no movement or loss of GPS coverage?

we only check for availability of the GPS subsystem once, at the start of the application.

I think your use case is, uhm, rare. In any case, if CamerAlert does not receive GPS updates it will also not use up any computer resources. All computations and updates are entirely triggered by receiving position updates. So if you disable GPS manually CamerAlert will basically pause.
