    Hi,
    I have an M5stack camera I want to use remotely. I can see images in a web browser, but I want to be able to get the data and manipulate and display in B4X apps (starting with B4J) . I think I need to use HTTPUtils2 to get the jpeg stream, put it in BitMapCreator, modify then display. Sorry but I have searched and cant find how to setup HTTPutils2 in B4J. The tutorial is for B4A. I also looked in esp8266 to see if there was example of reading from server thert in B4J and couldnt find anything.
    Can someone please point me in right direction, or help me onto the path if I have right idea.
    Thanks
    Steve

    With [B4X] SD_ImageView
    you can grab picture
    Code:
    #Region Project Attributes
        
    #MainFormWidth: 800
        
    #MainFormHeight: 600
    #End Region

    Sub Process_Globals
        
    Private fx As JFX
        
    Private MainForm As Form
     
        
    Private SD_ImageView1 As SD_ImageView
    End Sub

    Sub AppStart (Form1 As Form, Args() As String)
        MainForm = Form1
        MainForm.RootPane.LoadLayout(
    "Layout1"'Load the layout file.
        MainForm.Show
     
    '    Sleep(1000)
    '    SD_ImageView1.UrlBitmap="https://b4x-4c17.kxcdn.com/android/forum/data/avatars/l/0/1.jpg?1469350209"
        SD_ImageView1.UrlBitmap="http://10.169.145.54/jpg"
    End Sub

    'Return true to allow the default exceptions handler to handle the uncaught exception.
    Sub Application_Error (Error As Exception, StackTrace As StringAs Boolean
        
    Return True
    End Sub

    Sub SD_ImageView1_OneClick
     
    End Sub

    Sub SD_ImageView1_LongClick
     
    End Sub
    don't forget change IP
