Android Question Reflector vs JavaObject

[Caps64]

I am learning B4A and I would like to understand more about Reflector and JavaObject.
As far as I understand so far, the following code using Reflector:

Sub VideoFrameAtR(dir As String, f As String, ms As Long) As Bitmap   
    Dim r As Reflector
    Dim obj As Object
    Dim bmp As Bitmap    
    obj = r.CreateObject("android.media.MediaMetadataRetriever")
    r.Target = obj
    r.RunMethod2("setDataSource", File.Combine(dir, f), "java.lang.String")
    bmp = r.RunMethod3("getFrameAtTime", ms*1000, "java.lang.long", 3, "java.lang.int")    ' 3=OPTION_CLOSEST
    Return bmp
End Sub

should be the same of the following that uses JavaObject (that I find more easy):

Sub VideoFrameAt(dir As String, f As String, ms As Long) As Bitmap   
    Dim job As JavaObject
    Dim bmp As Bitmap
    job.InitializeNewInstance("android.media.MediaMetadataRetriever",Null)
    job.RunMethod("setDataSource", Array(File.Combine(dir, f)))   
    bmp = job.RunMethod("getFrameAtTime", Array(ms*1000, 3))
    Return bmp
End Sub

Then what is the difference between Reflector and JavaObject, if any ?
What code runs faster ?

 

[Erel]

No difference.

What code runs faster ?

It doesn't matter if this code takes 0.1ms or 0.12ms to run.

Thanks Erel.

 

[OliverA]

No difference.

Was I then under the false understanding that the Reflector class allowed access to private methods/objects/data whereas JavaObject class only allowed access to public information?

 

[Erel]

That's true. There is no difference in the example posted as the methods are public.
