I didn't find a way to implement it with Java. If you find then it will be possible to port it to Basic4android.

//Get a surface

//tells Android that this surface will have its data constantly replaced

Yes.

B4X:

Dim in As InputStream
in.InitializeFromBytesArray(data, 0, data.Length)
Dim bmp As Bitmap
bmp.Initialize2(in)

I'm sorry for bring in up this old thread but this is exactly what i need to do as well.
Can however not get the picture to display using this, is there something else that needs to be done?
I have put the above code right after the photo is taken.
