Android Camera system Development Umbrella __android

Recently engaged in the work related to the development of Android camera, found that this piece is still more complex, from the network also get a lot of relevant information, but are relatively dispersed, for the problems arise difficult to have a comprehensive understanding and positioning.

According to my own habits, I prefer the whole framework to understand first, and then for a part of a serious analysis, so in the case of problems can be targeted.

found that the system could not upload my picture, may be the reason for my local encryption, can only do it
