ARE you using Runtimepermissions? File.Dirrootexternal requires it starting from api 23.

    )
        
    
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
SetActivityAttribute(Main,android:windowSoftInputMode, "stateHidden|adjustPan")
'End of default text.
SetApplicationAttribute(android:theme, "@style/LightTheme")
CreateResource(values-v20, theme.xml,
