Android Question ZoomImageView - Compiling failed

[artsoft]

Hi!

There is a need to have a zoomable ImageView control (zoomable with two fingers) in my app. After taking a picture with the CamEx2 control I show the bitmap to the user in order to decide if the qualtiy of JPEG image is good enough to save the image or not.

So I looked for some solutions here and I found this one:

https://www.b4x.com/android/forum/t...platform-zoomable-pannable-image-view.119987/

The example works fine - but with my pure B4A app there is the follwing message from compiler which informs me about this:

Within the module tab I already choose the bx4lib:

And within the designer I can use the control:

My app is a pure B4A app and the the question is now: Is the error above based on the fact that this is not a pure B4X app?

Or perhaps is there another control or custom view which allows a finger IN-OUT-zooming of bitmaps?

Thanks a lot in advance.

Best regards

Hi Manfred, thx!
My URL above (within my first post) points directly to your link. It is the same control.

Have you selected the XUI library? That is where B4XView is defined.

Life can be so easy ..... Yes, you are right! The XUI lib was missing and was not included.
Thanks a lot for your help.
