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:

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.
