Camera

[jayel]

Hello,

When I try the example code "camera example" I can see a preview of my rear camera.
No when I implement the same code in my android app. (not the main activity bu t a second activity called "afbeelding". I don't see the preview window.
But when I click to take a picture, it does make a picture.

Can somebody help me please?

Greets,

John

Are you using CameraEx class?

It is impossible to say why it doesn't work in your project without seeing your code.

I see a line in the log : overlay_commit : Set Position - Parameters Error.

Isn't that the problem ?

and no i am using the cameraexample.
Because the other won't work with older versions of android.

If the camera example works and your code doesn't then you need to compare the two projects and understand why it behaves differently.
