B4A Library ProgressRoundButton

The attached project wraps this Github project. You need to have android-support-v4.jar in your additional library folder. You can download it from here. Posting the following:

1. The B4A project demonstrating the use of this library
2. The java code. You need to copy android-support-v4.jar to the libs folder should you want to compile the java code. The libs folder is on the same folder level as the src folder.
3. the B4A library files (jar and xml)

mmm, I downloaded it, and when I try to run it, the IDE complain with "Layout not available"
I had been checking, and sync the files etc, without any luck. I tested in the traditional google SDK emulator.

Have you downloaded android-support-v4.jar from the link that I have posted? You might have an older version of this file that does not contain all the necessary classes.

Hi Schoeman, yes you right , I had been reading so fast the post. It is working smoothly . Thanks you, that button, is very nice.
