Android Example AppCompat with ToolBar - minimal example

In most cases AppCompat is no longer needed and will only make things more complicated.
B4XPages example with dynamic menu: https://www.b4x.com/android/forum/threads/b4x-menu-badges.133301/

The project attached uses the powerful AppCompat library to replace the built-in ActionBar with a more robust ToolBar.

The NavigationItemClick event is raised when the icon is clicked.

You can set ToolbarHelper.ShowUpIndicator = True to show an up arrow instead. It will raise the same event.

You can change the toolbar color in the manifest editor.

Edit: depending on your Android SDK version, you might get this error:

java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/arch/core/executor/ArchTaskExecutor;

The solution is to add this line in the main activity:

#AdditionalJar: androidx.arch.core:core-runtime

Check the Appcompat tutorial on how to setup your App. CAREFULLY.
Seems you did forget something.
