Android Question install APK

I am unable to install an APK file made with B4X on an Android device. Not via B4A-Bridge and not manually. Android keeps saying: Not installed. The APK does work well in Windows with an emulator. I once started with B4A in about 2014 but haven't done anything with it for a long time. Do I need to change something about the key?
Attached is the source code of the app, intended to practice with B4X.

Problem solved. Community thanks. See: Share Your B4X Story/Using B4X Tips (?)

Check the unknown sources and enable it.

Also, try changing the Package Name of the project you are trying to install because sometimes if there is an existing app on the device with the same package name with a
higher version, it will say "Not Installed" because you can't install a lower version of the same app on a device.

The problem remains. Android says not installed.
On 2 devices: a tablet and a phone. In Windows with an emulator and in the emulator of B4X the APK runs smoothly.

(see also the earlier attached zip-file)
Do I have to do something about the manifest:
'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: https://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="29"/>
<supports-screens android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
CreateResourceFromFile(Macro, Themes.LightTheme)
'End of default text.

This in B4A:
#Region Project Attributes
#ApplicationLabel: The Thruth
#VersionCode: 4
#VersionName: 4.0
'SupportedOrientations possible values: unspecified, landscape or portrait.
#SupportedOrientations: unspecified
#CanInstallToExternalStorage: True
#End Region

#Region Activity Attributes
#FullScreen: False
#IncludeTitle: True
#End Region

What Android versions are on the devices that work and those that don't?
You've not used B4A for a long time, have you done a complete re-install?
If not, delete all files and folders, download and install everything fresh. https://www.b4x.com/b4a.html
