Android Example AppCompat with ToolBar - minimal example

In most cases AppCompat is no longer needed and will only make things more complicated.
B4XPages eExample 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:
B4X:
#AdditionalJar: androidx.arch.core:core-runtime

Talking about B4A you are right. But Erel said that the issue is related to the installed Build-Tools. It should be a NEWER one than you are using.

Install the newer 25.0.3.
DEINSTALL all versions <25

Follow your information and now it is working.. Thanks guys..

Why work created apps with me only from Android 5? As soon as I install the app on Android 4.x, it crashes directly.

I have issue with running it. :-(
Compile&Run is finished well, and no log entries loged in IDE. Then, apk is transfered well to B4A-Bridge, and is asking me to allow installation. And after that I got following screen which says that "App is not installed, as it's assumed that package is damaged". Any ideas ?
I have latest Android SDK build tools and latest jdk version.

This looks just what I need. I ran the demo fine, but when I tried to plug this onto my main menu on my app, it compiles ok, but it gives the following error, any ideas?

java.lang.RuntimeException: java.lang.ClassCastException: b4a.riskassessment.mainmenu cannot be cast to android.support.v7.app.AppCompatActivity
