Android Code Snippet SetNavigationBarColor - Change code of Navigation Bar by Code

I use this function to change color of the Navigation Bar (SDK > 21 = Android 5+) in some screens of my app that use Theme.Holo.Light.

Sub SetNavigationBarColor(clr As Int)
    Dim p As Phone
    If p.SdkVersion >= 21 Then  'versão 5.0
        Dim jo As JavaObject
        jo.InitializeContext
        Dim window As JavaObject = jo.RunMethodJO("getWindow", Null)
        window.RunMethod("addFlags", Array (0x80000000))
        window.RunMethod("clearFlags", Array (0x04000000))
        window.RunMethod("setNavigationBarColor", Array(clr))
    End If
End Sub

Unless you want to change the color at runtime then it is better to change them in the manifest editor: https://www.b4x.com/android/forum/threads/theme-colors.87716/
This way they will look correctly right when the app becomes visible.

Thanks, but this aproach is compatible with the "Theme.Holo.Light"?
I'm tried to use the code:

<color name="navigationBar">#ff006db3</color>

in this style:

<style name="MyAppTheme" parent="android:Theme.Holo.Light">
       <item name="android:navigationBarColor">@color/navigationBar</item>

without success.

Why are you using the holo theme on Android 5+ devices? Your app will look "old"...

Yes. In my app the "old" style look is better.

Better Way:

    Dim jo As JavaObject
    jo.InitializeContext
    jo.RunMethodJO("getWindow", Null).RunMethod("setNavigationBarColor", Array(Colors.RGB(42,49,55)))
