Answer by Ronny Bigler for How to remove all debug logging calls before building the release version of an Android app?

my Way:

1) enable Column Selection Mode (alt+shift+insert)

2) select on one Log.d(TAG, "text"); the part 'Log.'

3) then do shift + ctrl + alt + j

4) click left arrow

5) do shift+end

6) hit delete.

this removes all LOG calls at once in a java file.
