Does Obfs4Transport.setPropertiesFromBridgeString() qualify? I.e.

AndroidPluggableTransports/APTDispatchLibrary-MeekObfs4-Full/src/main/java/info/pluggabletransports/dispatch/transports/Obfs4Transport.java

Line 310 in 7b8b6f4

public static void setPropertiesFromBridgeString (Properties options, String bridgeLine)

Or were you thinking of something different? I was thinking of adding standard parsing methods for Bridge URLs here as well. https://trac.torproject.org/projects/tor/ticket/15035

yeah I think this is done WRT to the original request, though I need to make sure that method is also in the LEGACY module that is currently working.
