Android Question CameraEx Error in sample code

[Alwinl]

I downloaded the CameraEX library (1.20) to use with Camera lib 2.20 on Android 4.1.1. Using the sample code as-is I get the error below when taking a picture, it seems to be coming from 'cam.TakePicture' in the CameraEx library. The weird thing is that the photo seems to be ok after I dismiss the error.



An error has occurred in sub:cameraexclass_takepicture(B4A line: 100)
End Sub
java.lang.RuntimeException: takePicture failed
Continue?

Is there any error message in the logs?

The log says:

It fails to take the picture. There might be more information in the unfiltered logs. It is worth trying to change the parameters (picture size) before you open the camera.

There is no more info in the unfiltered logs, I have tried fiddling the parameters but still I get the error.

What is strange is that the photo always gets taken ie. Camera_PictureTaken gets called and I see the photo. Once in a while I get no error but 99% of the time I do get the error.
If I put error handling around TakePicture I think my problem will be solved, but I prefer to keep the libraries standard so I don't need to worry about the bits I've edited when downloading new versions.
