fix(android): findStateDrawableIndex reflection method

[m1ga]

Issue
When trying to read the backgroundColor when you only have a backgroundImage it will show this error:

TiUIHelper: (main) [0,184643] java.lang.NoSuchMethodException: android.graphics.drawable.StateListDrawable.getStateDrawableIndex [class [I]

findStateDrawableIndex is available since Android 29:
https://developer.android.com/reference/android/graphics/drawable/StateListDrawable#findStateDrawableIndex(int[])
getStateDrawableIndex is not in the list anymore.

Test:
I don't have the real app test case but this will trigger it too:

var win = Ti.UI.createWindow({});
var view = Ti.UI.createView({
	backgroundImage: "/images/appicon.png"
});
win.add(view);
console.log(view.backgroundColor)
win.open();

Note:
It will still show [WARN] TiUIHelper: (main) [649,649] Background drawable of unexpected type. Expected - ColorDrawable. Found - class android.graphics.drawable.BitmapDrawable but that is a warning from the SDK itself and expected since we don't have a color, just an image.
