Download a source from the remote repository, version control is the use of SVN. But a problem was found, and when the files were modified and deleted, version management was recorded. But if I create a new file, I find that it is not automatically associated to the VCs and cannot be manually added to the VCs, so that when I submit the code, I cannot submit a record of the new file and cannot add it to the version control system in Androidstudio and must manually add it to the file directory.
However, the answer was later found on the Internet.
The solution is simple.
Open File–>setting–>version Control, confirmation and when files is created you will see an add silence option, tick it out, then click Apply and restart Androidstudio. Of course setting's shortcut key is ctrl+alt+s.
Click OK and restart the software.
Androidstudio does not automatically add newly created files to VCs
