Question about the camera for QR codes

Hello there!

I'm currently making a game for android in Unity and I am also going to use QR codes for the levels. I was very surprised when I installed Mekorama that it didn't ask for a permission to use the camera nor to take pictures. And it didn't ask anything when I used the feature itself. Does anyone know how Martin Magni managed to open the camera and take a picture without requesting this permission?

Sorry for the very specific question and thanks for the help if any

 

Thanks a lot Gepeto for your answer! I saw after I posted also that in the android spec it says "Note: If you are using the camera by invoking an existing camera app, your application does not need to request this permission.". So I guess that is what Martin is doing.
I'm going to try to see if I can start the default camera from the code in Unity. It seems feasible!

 

I figured it out! It was indeed just a matter of calling the default camera, but it's a bit more complicated in Unity than it is in a native android application. I have put the solution code on github "Unity-for-Android-Read-Write-QR-Code-from-Camera"!

 

Hello hello!

I have finished my game for android so don't hesitate to check it out. It has a puzzle editor and QR codes like in Mekorama (from where I got the inspiration for this feature! ).
