Do you have Appcompat library 4.0 in your library list?

 

[KHALID SHOKRY]

yes I have it

 

[KHALID SHOKRY]

 

[Marvel]

You need to download the library files here and extract it to your additional library folder

[KHALID SHOKRY]

I did that already before I try
I changed the Jar folder path also as seen in the pic

 

[Marvel]

Which pic are you referring to?

 

[Sagenut]

Where is the B4AImageSlideShow library?
It's not enabled even in the case that it's present.

It's not enabled even in the case that it's present.

I use all the lib in the project folder
Can you plz download the project and try it
or how can I get B4AImageSlideShow library

 

[Sagenut]

The demo project that you started from looks incomplete to me.
It seems that it's missing a Class or a Library.

 

[Sagenut]

I see other members with the same problem.
The missing file should be supplied by the original author of the demo.
Sorry, but we can do nothing.

 

[Sagenut]

I would suggest you to create a similar solution by yourself.
This can be a good starting point:
XUI Image Slider
Hope it can help you.

 

[KHALID SHOKRY]

thanks a lot
I well try to do that

Is main.bal visible in the Files tab of the IDE when you open the B4A project?

There should also be files in the /Object/res/layout folder and Object/res/drawable folders of the B4A project once you have unzipped the B4A project. Make sure these files are set to READ ONLY before running the B4A project for the first time else the files in the two Object/res/xxxx folders will be deleted during the first compile of the B4A project.
