B4A Library ColorPickerLibrary

It comes from here. You need to add some Java code to the library in order to return the selected colours to the B4A activity - not difficult to do. Leaving it up to you...

1.Extract LibRes.zip and copy the extracted folder to be on the same folder level as that of the /Files and /Objects folders of the B4A project
2. Extract DemoRes.zip and copy the extracted folder to be on the same folder level as that of the /Files and /Objects folders of the B4A project
3. Extract resource.zip (see post #2) and copy the extracted folder to be on the same folder level as that of the /Files and /Objects folders of the B4A project
4. Copy the library files to your additional library folder.
5. You will also need the following in your additional library folder
a. a recent version of android-support-annotations.jar
b. a recent version of android-support-v4.jar
c. a recent version of android-support-v7-appcompat.jar​
6. You also need to download AppCompat V3.20 and (at least) DesigSupport (V2.00) from the forum and have them in your additional library folder.
