Only last photo is saved when using camera.takePicture() multiple times?

The call to takePicture is asynchronous, that is why you pass in a callback, which, is fired when the photo data is ready. When you call takeFocusedPhoto() back to back, all of them are getting fired BEFORE even the first takePicture is. Looking at the method body of takeFocusedPhoto you are setting the class member variable filename equal to the name argument.

What this means is that filename is getting set to a, b, c and then d before jpegCallback gets fired, which means your are saving each photo to d. You are going to need a better way to get the filename in jpegCallback.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
