Android Question focus mavic camera

[shb777]

I flew my mavic drone close to dusk today, with my b4a program, but the video was out of focus
the whole time, and I found I had no way to focus with my program. Is there any way to focus,
like the dji go 4 touch to focus? steve

You can use this code to set the focus target:
https://developer.dji.com/api-refer...mera_camerasettings_setlensfocustarget_inline

Sub SetCameraFocusTarget(x As Float, y As Float)
   Dim pf As JavaObject
   pf.InitializeNewInstance("android.graphics.PointF", Array(x, y))
   Dim cc As Object = pf.CreateEventFromUI("dji.common.util.CommonCallbacks$CompletionCallback", "callback", Null)
   GetNativeCamera.RunMethod("setFocusTarget", Array(pf, cc))
   Wait For (pf) Callback_Event (MethodName As String, Args() As Object)
   If Args(0) = Null Then
     Log("Focus set successfully.")
   Else
     Log("Error setting focus: " & Args(0))
   End If
End Sub

Sub GetNativeCamera As JavaObject
   Dim jo As JavaObject = camera
   Return jo.GetFieldJO("camera")
End Sub

Note that the x and y values are between 0 to 1.

You can handle the pnlCamera touch event and then call SetCameraFocusTarget.

OK thanks. so the middle of the screen would be 0.5, 0.5

Just tested it indoors, and it definitely seems to be working! Thanks Steve

Public answers together with a working search engine is the key for building a knowledge base.

Next year someone will search for "drone focus" and will find this post.
