Update: My large project will not work with Materialcon 2.0 using B4A 8.80. Material Icon 1.5 works ok with B4A 8.80 but B4A 9.00 will not work. MaterialIcon 1.5 and 2.0 will not work with B4A 9.00.

You don't need to use any library to display material icons. Just add a label and set the font to material icons.

I've downloaded MaterialIcons v2: https://www.b4x.com/android/forum/threads/2046-materialicons-in-the-color-you-need.56612/#content
The example works fine here with v9.00 beta #2.

I have emailed you my project. It only crashes with a very large project. I want to use MaterialIcon for my customlistview. It has more icons that i need. I dont want to rewrite my customlistview. You can reproduce the error with my project.

Material Icon 1.5 works great in v9.00 release #4. Good Job.

Erel, I sent you an updated CustomListView with material Icon 2.0 Lib. This will crash on Release #4 or any B4A version. Hopefully this is resolved and crashes only with my app.

This is a different issue which is not related to this thread.

The logs tell you the error:

It happens because the class name is slightly different in MaterialIcons v2.0. You will need to remove the existing MaterialIconView views and add new ones instead.

You are correct. I removed the MaterialIcon in designer and added a new one and worked ok. Thanks Erel.
