I am having trouble opening 2 hardware cameras at the same time. I have tried both the CameraEx and Camera libraries. It seems that initializing the second camera breaks the initialization of the first camera. It produces a "java.lang.RunTimeException: Method called after release()" error. Each camera works fine if I comment out the other initialization.
Is there a work around so I can preview both cameras at the same time?
Thanks,
EJ

Sub Globals
Dim Panel1 As Panel
Dim Panel2 As Panel
Dim frontCam As Camera
Dim backCam As Camera
End Sub
Sub Activity_Create(FirstTime As Boolean)
Activity.LoadLayout("lg")
Dim numberOfCameras As Int = r.RunStaticMethod("android.hardware.Camera", "getNumberOfCameras", Null, Null)
ToastMessageShow("# of cameras" & numberOfCameras,True)
End Sub
Private Sub InitializeCameras
frontCam.Initialize2(Panel1,"frontCamera",1)'' the first camera initialized produces an error when starting its preview
backCam.Initialize2(Panel2,"backCamera",0) '' the second camera initialized runs fine.
End Sub
Sub backCamera_Ready (Success As Boolean)
If Success Then
backCam.StartPreview
Else
Msgbox("cannot open back camera","")
End If
End Sub
Sub frontCamera_Ready (Success As Boolean)
If Success Then
frontCam.StartPreview'' This raises an error "java.lang.RunTimeException: Method called after release()"
Else
Msgbox("cannot open front camera","")
End If
End Sub
Sub Activity_Resume
InitializeCameras

Sub Activity_Pause (UserClosed As Boolean)
frontCam.StopPreview
backCam.StopPreview
frontCam.Release
backCam.Release
