Hello,
Is it possible to change the color of the android native button bar? I like to change grey to black so that the color theme would match my app.
Thanks in advance!

Just as a guess I'd think it would not be allowed by the android OS.

In the Colors tab of the Inspector you should have an option for setting the Background Color, no?

Hi bogs, FourthWorld,
I tested by setting all colors black in the inspector, but the color of the navigation bar does not change. Any walkaround with manifest file?

I don't know of a workaround. The best I can recommend is to dive into the widget code to fix it, or submit a bug report for the team to do so.

Sorry Jellobus, I don't dev for mobile of any kind, but as I said in my first post, since the nav bar is provided by the Android OS, and not Lc, I really doubt there is any way you are going to change anything about it. Just an opinion on my part.
There
*is* an api for it, which you can find out about
here...
setNavigationBarColor
Added in API level 21
public abstract void setNavigationBarColor (int color)
Sets the color of the navigation bar to . For this to take effect, the window must be drawing the system bar backgrounds with WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS and WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION must not be set. If is not opaque, consider setting View.SYSTEM_UI_FLAG_LAYOUT_STABLE and View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION.
The transitionName for the view background will be "android:navigation:background".
Related XML Attributes:
android:navigationBarColor
...but I have no idea whether Lc can take advantage of that or not. Maybe Jacque (or someone that actually builds stuff for android) knows
but I really
really doubt it is a bug, per se, since it is not part of your app.

Good find, Bogs.
Widgets are written in LiveCode Builder, which provides a scripting interface for OS APIs, so this seems quite doable.
Whether this is a bug per se or an enhancement request may be a matter of opinion. Personally, since the color is unresponsive to the UI provided in the Inspector I'd consider it a bug.
But either way, unless someone here is in a position to add support for that to the widget a bug report will be needed to bring it to the team's attention.
