Android Question Adding image to resource folder

[Tim Chapman]

In this example, a resource folder is used:

Material Design 4 - Modifyable and advanced Menu

Note: You should use B4A 6.0 or above for this tutorial. With the ACToolBar(Light|Dark) object we can get access to the Menu object of the activity. This opens the possibility for modifyable menus and some other advanced menu features. Basics With the ToolBar.Menu property we have access to...

In that folder are 5 folders with the same images of different sizes.
These are used by the xml.GetDrawable command.
There is an image for refresh.
I flipped each refresh image so that it looks like go back instead of refresh and saved it to the same folder with a new name. Same name in all 5 folders.
I then used the xml.GetDrawable command and referenced my new image.
I get this error: android.content.res.Resources$NotFoundException: Resource ID #0x0
I know I have the correct name for the new image without the extension the same as the command is used in the example with the original images.

Is there some other step I need to take to add a file to the resource folder?

There is really no reason to use this library. It was relevant when Android 4 was popular and it allows bring the Material theme, which is the default theme on Android 5+, to Android 4.

What should I use instead of this library?

 

[Erel]

No library is needed.

How do I modify the menu without that library?

[B4X] [B4XPages] Menu badges

This is a B4i + B4A example. It adds a dynamic badge to the menu icon. It also shows how to update menu items at runtime. Don't miss: 1. B4A - theme settings in manifest editor. 2. B4i - theme settings in main module. Both are not really needed for this example but are useful.

Thank you. I will check it out. Just for my understanding, is there something I am missing about adding a picture the resource folder above? Why doesn't that just work?
What is the nuance that I am missing here?

I understand from what you describe that you are using the device of a flipped image. However, you do not say what goal you want to achieve with this. Alexander Stolte has created a whole series of menus. Perhaps there is one that will be of interest to you.
