Android Question Method: setCustomDensity not matched.

[watesoft]

I inline java in B4A.
Java Method:

public void setCustomDensity(@NonNull Activity activity, @NonNull final Application application)

B4A:

Dim JO As JavaObject
JO.RunMethod("setCustomDensity",Array(Activity,Application))

Error occurred: java.lang.RuntimeException: Method: setCustomDensity not matched.

How to use this method correctly？

Where does setCustomDensity come from? Post the link to its documentation.

It's a custom method to adapt various Android devices and no documentation . I found it in a chinese forum.I just want to know how the parameters in setCustomDensity match the parameters in JavaObject.

This is important information.
I can tell you that this method is a waste of time and is not the correct way to handle different screen sizes.

JavaObject.InitializeContext will return the Activity object which is also an Application object.
