    The application take one picture with the back camera save , switch to frontal camera and take another picture and save the picture and exit.

    This is for security application

    I tested the application in android 7.1.1 and works.
    When I try with android 8 it takes the first picture save is ready for the second and freeze.

    I wait for more then 5 minute and if you don´t press home button the screen is freezed.

    This is a transparent activity so you see the icons but you can not access them

    Code:
    camEx.TakePicture
        
    Wait For Camera1_PictureTaken (Data() As Byte)
    If someone could help

    Does it work if you sleep before reopening the camera:
    Code:
    Sub ChangeCamera_Click
       camEx.Release
       Sleep(
    1000)
       frontCamera = 
    Not(frontCamera)
       InitializeCamera
    End Sub
    ?

    I had the Sleep(800) just in camera1_ready but just before the first shoot.
    Now I call Sleep(800) before shoot the second and works.

    Do you believe that is better the sleep command before initialize the camera or before the shooting inside camera1_ready ?

    Thanks

    You will need to test it. Worth trying with Camera2 library.
