Could you read these ports out from build/android/pylib/constants.py instead?
Maybe even keep the list up to date there?

Maybe it would be easier to write this in python then? Or at least provide some
help for doing that which does not include grepping or ugly bash-trickses to
parse the .py file? Maybe create a helper function in constants.py you could
call from here?

+    -R 10000:localhost:10000 \
+    -R 10201:localhost:10201 \
+    "$remote_host"
