Android Question CameraExClass module don't works under old Android version (2.2) ?

[DOM85]

Hello,
I tried to run CameraExClass exemple on a small smartphone (only 1 camera) under Android 2.2 and it failed.
I tried also to make a new app with the CameraExClass module on the same smartphone, it failed also.

Error messages :
LogCat connected to: B4A-Bridge: Samsung GT-I5510-356368041246647
cameraexclass_findcamera (B4A line: 46)
cameraInfo = r.CreateObject("android.hardware.Camera$CameraInfo")

I know that it is not always possible for B4a to keep compatibility with all old versions of systems, but many users have yet old smartphones.

Would there be a way that CameraExClass module works on both new systems and old systems (to have only one app)?

Thank you for your help or any explanation.

CameraExClass works on Android 2.3+, it don't works on 2.2

I had the same problem with my customers, but I have not found a solution, so my customers have update the devices

Ok, if CameraExClass works on Android 2.3 it will be enough for my users.
Thank you Sergio.

My experience - it does not work on 2.3 , only on higher versions.

I have an app with CameraExClass working on a LG-E400 phone device with OS 2.3.6

It should work on Android 2.3+.

Sorry, checked again - my "not working devices" are 2.2

This discussion gave me a push and I managed to make the cctv work with 2.2 android - without the camex, just the camera library, not using the additional properties.
I copied sub PreviewImageToJpeg from the camex and put it to the application as is.
