Getting channel's ID, how? [answer: roAppInfo.getID()]

Question

I wonder how a program running on Roku can figure out its channel ID? The (mostly) numeric ID that's used to /launch or /input to.There are situations that can be useful, one is for a shared/library code between different channels. Another one i have at hand is, say i have two of the same channels - one with ID "12345", the other one "23456". 12345 is a beta, 23456 is a release - they are exactly the same as code base and even use the same registry but need to act a hair differently - say one shows a "beta" placard. So if when started, the code can check "who am i?" - then it can implement that local difference based on hearing back the ID.Seems to me appropriate place for this is a method (getSelfID? getAppID?) in roDeviceInfo but nothing related i can find so far.

is roAppInfo's GetID() not what your looking for?

Even though I answered that question I never actually thought of doing that till you asked, now my statistics dashboard can distinguish between dev (sideloaded), testing, and production.  Realized that once we got published knowing if I'm seeing a pattern or issue in test or in production was a huge need.  A case where I really am glad you asked.

A case where I really am glad you asked."You are welcome!"   :mrgreen: Watch out for my new book "How to Ask the Right Questions (or On Strategic Ignorance)" A bit more serious, i call this the Docendo discimus (Latin "by teaching, we learn") effect. At least I find myself understanding things better by answering questions here, StackOverflow etcCongrats on getting published (8/11), btw!Ha! 51 channels published on 8/13. FIFTY ONE. In one day. Really?! I wonder if there is a day (once a month? once a quarter?) when the Co says "oh, f**k it - open the gate, flush the queue, everybody gets a pass"?

Just for fun, here's how I did it before getID() was implemented. Anyone writing private channels they want to run on Legacy will still need something like this to get the Channel ID (mIght be some bugs in this code, esp. with regards to handling side-loadedness):


'exerpted from a set of private functions in an AA

    ChannelID:  function () as string
                    'get ip from deviceIP function
                    ip=m.deviceIP()
                    m.ipAddress=ip
                    'read manifest file from local storage                
                    manifest=readAsciiFile("pkg:/manifest")
                    
                    'convert manifest file into array delimited by carriage returns                
                    phase1=manifest.tokenize(chr(10))
                    
                    'iterate through result and find app title
                    for each line in phase1
                        if lcase(line.left(line.instr("=") ) )="title" then
                            apptitle=line.mid(line.instr("=")+1)
                        end if
                    end for
                
                    'to do: handle case if no title field in manifest
     
                    'get list of apps from device ECP

                    Identity=""
                    if xml.parse(data) then
                        ?"iterate through all apps in list and find one where the title matches manifest title"
                                                   
                        for each entry in xml.app
                            if entry.getText() = apptitle.trim()
