Marcin,
You have an interesting problem.
ProGuard analyses the calls you have specified and only if it can
determine that there is no return value, then the call gets removed.
It is hard to speculate, what each call to Log.d("foo") can cause, and
whether ProGuard can actually trace that there are no side effects.
You can help ProGuard by having a central singleton Logger and each
class requesting child Logger from this one. Then, when you release,
setting the logger level to OFF on that master logger should give
ProGuard enough to establish that none of the Log calls will ever take
place therefore removing them.
If that does not work, static final boolean IF switch around each call
to Log is your only help.
Hope it helps somehow.
