This article implements the Android system camera call to take photos
The layout of the project is fairly simple, with only one button:
First open the list file under the Packages\apps\camera folder and find the following code:
The relevant code is as follows:
public class Mainactivity extends activity {

On the audio and video calls in the process of minimizing the implementation of this function, similar articles on the network, but it seems to have not seen the clearer explanation, here because the project needs to achieve such a function, today I recorded it down, on the one hand for later use to facilitate their own access, On the one hand also give people who need to provide a train of thought, let everyone less detours. Here I also refer to some
