Overview of Android Camera System Development

 

 

I recently worked on Android camera development and found that this is still complicated. I also got a lot of related information from the network, but it is scattered, it is difficult to have a comprehensive understanding and positioning of the problems that arise.

According to my habits, I prefer to take a rough look at the entire framework and conduct a careful analysis on a certain part. In this way, when a problem occurs, I can be targeted.

 

I found that the system could not upload my images. It may be because of my local encryption.
