Android Question JavaObject should be initialized

[Dianzoa]

I got this error after trying to use SpaceNavigation lib and add appcompatActivity, also the SDK manager install some things after adding those libs. But now I got this error when calling this code, before it worked well. Maybe the actionbar can not be used with the SpaceNavigation bar?

Sub SetActionBarColor(Color As Int)
    Dim jo As JavaObject
    
    jo.InitializeContext
    Dim cd As ColorDrawable
    cd.Initialize(Color, 0)
    jo.RunMethodJO("getActionBar", Null).RunMethod("setBackgroundDrawable", Array(cd))

This is the LOG

does not seem to be related to SpaceNavigation
SpaceNavigation is not a replacement for an ActionBar.

 

[Dianzoa]

I think that too, but if I add the javaobject to the simplest example of space navigation, it gives the same error. I use the example that comes with the lib

Edit: Using 8.50v

sure. You can not get a ActionBar from an Object where there is no actionbar inside.

Ohh yeah, sure, but the error I think has nothing to do with the bar itself, but the javaobject instantiation or something, cause in my app I have the action bar, and the error is in the same line of code in both project
Edit: Maybe the appcompat makes a difference? I didn't use that before trying space lib. I don't have the code right here. It's 4:10am here, I will make more tests after some sleep. Cheers.
