Taking a Photo After Attempting a Failed Unlock Code

[Wayne E]

Is there a way using Tasker to fire a task (in this case, take a
photo, ideally with the front-facing camera) when a failed attempt to
enter the unlock code is made? Perhaps with a third-party lockscreen
(I haven't seen one that provides callbacks)?

This would be similar functionality to the RedHand app on Mac (http://
download.cnet.com/RedHand/3000-2162_4-10920807.html).

Thanks,

You mean the keyguard unlock pattern ?

There's an Android callback for failed password entry, not sure if
that applies to the lock pattern as well.

Will put it on todo to check it out.

Pent,

I can't find a good definition, but is the "keyguard" another word for
the default Android unlock screen? If so, then yes. I typically see
either the standard swipe to unlock or the pattern unlock, but I guess
any failed authentication method is the end goal (PIN or password or
some other future method).

Is addressing the front-facing camera specifically possible with
Tasker (i.e. on the Thunderbolt)? I don't have one, but my friend is
getting one and we were looking into some Tasker security options.

Ah yes, missed that bit. I havn't looked recently to see if it's made
it into the Android API but it is on the todo list already.

Thank you for considering this! Here is the API for the cameras
(2.3) It would also be nice to http post a picture as well (get a low-
res pic bin64 in a system variable)

------ from http://developer.android.com/sdk/android-2.3.html ----
Multiple cameras support

Applications can now make use of any cameras that are available on a
device, for either photo or video capture. The Camera lets
applications query for the number of cameras available and the unique
characteristics of each.

* New Camera.CameraInfo class stores a camera's positional
characteristics (orientation, front-facing or back-facing).
* New getNumberOfCameras() and getCameraInfo() methods in the
Camera class let applications query for the cameras available and open
the camera that they need.
* New get() method lets applications retrieve a CamcorderProfile
for a specific camera.
* New getJpegEncodingQualityParameter() lets applications obtain
the still-image capture quality level for a specific camera.

To look at sample code for accessing a front-facing camera, see
CameraPreview.java in the ApiDemos sample application.

The Camera API also adds:

* New parameters for cameras, including focus distance, focus
mode, and preview fps maximum/minimum. New getFocusDistances(),
getPreviewFpsRange(), and getSupportedPreviewFpsRange() for getting
camera parameters, as well as setPreviewFpsRange() for setting preview
framerate.

Cool, thanks, hadn't noticed that had slipped in with Gingerbread.

This is a great idea, too bad Thunderbolt is still on 2.2.
Perhaps by the time Tasker gets this feature Thunderbolt will be
updated by HTC.

It's a bloody superb idea, particularly if it can then email the
picture somewhere so you can see what git has nicked your phone!

If you have WidgetLocker, the 3rd party event for WidgetLocker Unlock
has never failed me. Unfortunately taking a picture from the rear
facing camera is of limited utility.
