HELP! Activity destroy timeout after screen lock

sally3599 · Aug 17, 2012

Here is the code:

'Activity module
Sub Process_Globals
   'These global variables will be declared once when the application starts.
   'These variables can be accessed from all modules.

End Sub

Sub Globals
   Dim camera1 As Camera
   Dim btnTakePicture As Button
   Dim Panel1 As Panel
End Sub

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("1")
End Sub
Sub Camera1_Ready (Success As Boolean)
   If Success Then
      camera1.StartPreview
      btnTakePicture.Enabled = True
   Else
      ToastMessageShow("Cannot open camera.", True)
   End If
End Sub

Sub Activity_Resume
   btnTakePicture.Enabled = False
   camera1.Initialize(Panel1, "Camera1")
End Sub

Sub Activity_Pause (UserClosed As Boolean)
   camera1.Release
End Sub

Sub Camera1_PictureTaken (Data() As Byte)
   camera1.StartPreview
   Dim out As OutputStream
   out = File.OpenOutput(File.DirRootExternal, "kara.jpg", False)
   out.WriteBytes(Data, 0, Data.Length)
   out.Close
   ToastMessageShow("Image saved: " & File.Combine(File.DirRootExternal, "kara.jpg"), True)
   btnTakePicture.Enabled = True
End Sub

Sub btnTakePicture_Click
   btnTakePicture.Enabled = False
   camera1.TakePicture
End Sub

I just run this app and leave it alone, then it show a error message when unlock screen, here is the log:

You should redim the Camera object after it is released:

Code: Copy

Dim camera1 As Camera
camera1.Initialize(Panel1, "Camera1")

sally3599 · Aug 17, 2012

it still shows the error

Thanks Erel.

Do you mean:

Code: Copy

Sub Activity_Resume
   Dim camera1 As Camera
   camera1.Initialize(Panel1, "Camera1")
End Sub

But it still shows that error.

Does it has any way to disable screen lock when this app running?

Erel · Aug 18, 2012

Can you upload your project (File - Export as zip)?

sally3599 · Aug 18, 2012

here is the zip

I found the screen of many Camera app never lock, is there any solution to force screen on when this app running ?

Any help will be appreciate it.

Erel · Aug 19, 2012

Your posted code is different than this code. I changed it to Camera instead of AdvancedCamera and it works properly (it is recommended to remove the Activity.Finish line from Activity_Pause).

Thanks Erel.

is there any solution to force screen on when the app running ?
Thanks

Yes, with PhoneWakeState from the Phone library.
