问题
I'm using Phonegap 2.3.0 and the new ForegroundCamera plugin from Google Code.. I followed the instructions carefully, and in my Eclipse setup I got the following errors when validating the project:
- Cannot cast from ForegroundCameraLauncher to Plugin
- ctx cannot be resolved or is not a field (x2)
- R cannot be resolved to a variable (x4)
- The method success(PluginResult, String) is undefined for the type ForegroundCameraLauncher
Now, I solved the first three of the above errors by updating some deprecated code lines (I hope I got it solved - it doesn't show the errors anymore)..
The first error was corrected by changing Plugin to CordovaPlugin in the line "import org.apache.cordova.api.Plugin;" in ForegroundCameraLauncher.java. ctx was replaced with cordova.getActivity() at those two places, where it caused trouble. This thing with R was fixed by doing some library changes which made it create an R object (sorry, I don't know how to explain this the right way, as I'm not too experienced with Eclipse yet).
With the last one of the four error messages, I tried to make a temporary fix by commenting out those two lines in ForegroundCameraLauncher.java (the lines with "this.success"...). But when taking a picture in my app, it crashes the whole thing upon returning from the camera instance..
Anyone know what's going on? I'd really be happy to get a few pointers here :)
The last error is obviously the one you should be focusing on ;) I just wanted to include some of the error fixing process, if others have experienced the same errors.

See this commit to see what has changed in Cordova: https://github.com/apache/cordova-android/commit/205215d409c4f75e958a9c09c0b4a38bd9a859ac
Replacethis.success(new PluginResult(PluginResult.Status.OK, getRealPathFromURI(uri, this.ctx)), this.callbackId);
withthis.callbackContext.success(getRealPathFromURI(uri, cordova));.
Update the execute function as per that commit, and update takePicture.
After that I have the ForgroundCamera plugin working with Cordova 2.3. Going to do some more testing and clean up now.

We have just updated Foreground Camera Plugin to work with Phonegap 2.4.0 and we are working on Foreground Gallery Plugin too. Please see http://code.google.com/p/foreground-camera-plugin/ and http://code.google.com/p/foreground-gallery-plugin/, and let us know (post an issue) if you have any problem.
See ya!
