Issue
I want to delete all comments in an android project, all the comments start with //
or any other specific characters?
Solution
Note: I’m answering myself I figure it out
In android studio, right-click on the project and select Replace in files, a new window pop up
1 in the first search field tape in this ^s+//.*$
2 in the second search field, keep it empty if you just want to delete all the lines that start with //
3 now hit replace all button.
if you want to delete other lines that start with different characters, example @
the expression should be like this ^s+@.*$
