I'm concerned - when I take a picture, I usually (ie, last week) am able to share the image to my app.
Now, however, only Google + contacts appear as share targets. For example, if I turn off sharing to G+, I get no Share options at all, only a greyed-out Share dialog that says "Visit google.com/myglass to add friends"
However, when I go to that address I clearly see my app and a number of contacts (who aren't in G+) who also usually show up.
Has something changed to cause this behavior? For example, is the code listed in the starter-project no longer sufficient to register a share target for photos?
For example, I could imagine that suddenly the acceptTypes[] parameter was now mandatory. But I'd love to hear someone closer to the API weigh in, if possible.
Thanks!

I solved this by following Alain's comment's advice.
It's very easy to think that the "Contacts" page you see at https://glass.google.com/myglass is all there is.
But if you want your app to receive shared stuff, you have to go here: https://glass.google.com/myglass/share

So I am currently working on this project and I am confused on how to tackle this issue I am having.
I am creating this website that will go behind the scenes and input the data the user is providing us with and checking to see availability on various websites. I am confused on how the logistics of this would work. Would it make more sense to use API's rather than create maybe a bot (I don't even know if this would work) or even if there was a way to code it in myself.
A similar platform to what the general idea behind what operations would be used is vaccines.gov where the system will display the availability of vaccines nearby (a value inputted by user is zipcode). I just need to be pushed in a general direction as I am unsure how to approach this.
Thank you!
I want to push card into my app in the Google Glass, and not to the timeline, my app in the glass contains cards with names of friends, I want to give ability to each one of the friends sending card under the friend name.
I will be happy to know if this behavior allowed, Thanks.
It depends exactly what you mean. In general, it is best not to think about specific apps when it comes to Glass, but rather to think about actions that take place using Glass. So instead of "starting" an app that shows the names of each person, we might instead think about wanting to send a note to that person and have that person be on our contact list to get a note if we wish to send them one.
Doing it this way, your Glassware needs to create and maintain contacts and register them with the TAKE_A_NOTE action. See https://developers.google.com/glass/v1/reference/contacts for more details.
It isn't clear what you are trying to do exactly, but it sounds like you might be able to use card bundles as well. Take a look at https://developers.google.com/glass/develop/mirror/static-cards#bundling_cards to see if this scheme will work for you.
If you're not doing it either of these ways - you may need to update your initial question to clarify how you are starting and running the app itself and how you picture the entire workflow.
my knowledge on how a database exactly works is close to zero and I'm trying to understand when exactly a site uses it's database to retrieve information. So for example the site retrieves all the information the moment i load the site(so when i choose for example "funny pictures" it doesn't have to retrieve anything from the database) or it retrieves information only when i make a specific choice? I hope you kind of understand my question, I'm sorry for my bad English.
It depends how it has been implemented and with whihc technology.
Most of time, It load a specific set of information only relevant of the current context.
It depends on SW technology used, settings and site code. Normally it is set to show something only when needed, but it is possible to change this behaviour.
There is one more possibility you haven't noticed, but often used - for example, you have a set of pictures. You see all their small icons on the page, but the whole picture - only if you click on an icon. Then while you are looking on the icons, or on one of the pictures, others pictures are downloaded at the background, to be quickly shown when needed. Sometimes even some primitive prediction system works, to guess what you'll look at the next time.
And all these behaviours work not only for data from databases, but for all data on the pages.
Again, the main thought - it is for you to choose.
I'm stumped and need some ideas on how to do this or even whether it can be done at all.
I have a client who would like to build a website tailored to English-speaking travelers in a specific country (Thailand, in this case). The different modes of transportation (bus & train) have good web sites for providing their respective information. And both are very static in terms of the data they present (the schedules rarely change). Here's one of the sites I would need to get info from: train schedules The client wants to provide users the ability to search for a beginning and end location and determine, using the external website's information, how they can best get there, being provided a route with schedule times for the different modes of chosen transport.
Now, in my limited experience, I would think the way to do that would be to retrieve the original schedule info from the external site's server (via API or some other means) and retain the info in a database, which can be queried as needed. Our first thought was to contact the respective authorities to determine how/if this can be done, but this has proven to be problematic due to the language barrier, mainly.
My client suggested what is basically "screen scraping", but that sounds like it would be complicated at best, downloading the web page(s) and filtering through the HTML for relevant/necessary data to put into the database. My worry is that the info on these mainly static sites is so static, that the data isn't even kept in a database to build the page and the web page itself is updated (hard-coded) when something changes.
I could really use some help and suggestions here. Thanks!
Screen scraping is always problematic IMO as you are at the mercy of the person who wrote the page. If the content is static, then I think it would be easier to copy the data manually to your database. If you wanted to keep up to date with changes, you could then snapshot the page when you transcribe the info and run a job to periodically check whether the page has changed from the snapshot. When it does, it sends an email for you to update it.
The above method could also be used in conjunction with some sort of screen scaper which could fall back to a manual process if the page changes too drastically.
Ultimately, it is a case of how much effort (cost) is your client willing to bear for accuracy
I have done this for the following site: http://www.buscatchers.com/ so it's definitely more than doable! A key feature of a web scraping solution for travel sites is that it must send you emails if anything went wrong during the scraping process. On the site, I use a two day window so that I have two days to fix the code if the design changes. Only once or twice have I had to change my code, and it's very easy to do.
As for some examples. There is some simplified source code here: http://www.buscatchers.com/about/guide. The full source code for the project is here: https://github.com/nicodjimenez/bus_catchers. This should give you some ideas on how to get started.
I can tell that the data is dynamic, it's to well structured. It's not hard for someone who is familiar with xpath to scrape this site.
The ways I can think of are:
Measure the time between actions.
Compare the posts' content (if they're too similar to each other) or, better yet, only the posted links.
Checking the distribution over a period of time the user is active (if the user is active, say posting once every hour, for a week, then either we have a superman or a bot here).
Some special activity expected: like in stackoverflow, I would expect users to press their user name link (top middle) to see their new answers, comments, questions etc.
(added by chakrit) Number of links in a post.
Not heuristic. Use some async JS for user login. (Just makes life a bit harder on the bot programmer).
(added by Alekc) Not heuristic. User-agent values.
And, How could I forget Google's approach (mentioned down by Will Hartung). Give users the ability to mark someone as Spam, enough Spam votes means this is a Spam user. (calculating what is enough users, is the work here).
Any more ideas?
I might be over estimating the intelligence of bot creators, but number 6 is completely useless against any semi decent bot creator. Using the C# browser control to create your bot would pretty much render 6 useless. From what I've seen with that type of software that's a pretty common approach.
Validating on the useragent is pretty much useless too all of the blog spam I use to get was from bots appearing to be valid web browsers.
I use to get a lot of blog spam. I would literally be deleting hundreds of comments a day. I made use of reCaptcha and now I might get 1 a month.
If you really try to make something like this. I would attempt by doing the following:
User starts off with no ability to post a url.
After X number of posts have been analyzed in relation to the other posts in the thread then give them access to post urls.
The users activity on the site, the post quality, and what ever other factors you deem necessary will be a reputation for that users IP.
Then based the reputation of the IP and the other IPs on the same subnet you can make other decisions on whatever you want.
That was just the first thing that came to mind. Hope it helps.
The number of links in a post.
I believe I've read somewhere that Akismet use the number of links as one of its major heuristics.
And most of spam comments at my blog contains 10+ links in them.
Speaking of which... you just might want to check out the Akismet API itself .. they are extremely effective.
How about a search for spam related keywords in the post body?
Not a heuristic but an effective approach: You can also keep up-to-date with the stats published by StopForumSpam using their APIs.
Time between page visits is common I believe.
I need to add a comment section to my personal site and am thinking of asking people to give me their email address; I'll email them a "publish comment" link.
You might want to check if they've come from a Spam blacklist IP address (See http://www.spamhaus.org/)
There is another answer that suggests using Akismet for detecting spam, which I completely endorse.
However, they are not the only player on the block.
There is TypePad AntiSpam which uses the same heuristics as Akismet, as well as the same API (just a different URL and api key, the structure of the calls is the same). It can be safe to say they pretty much take the same approach as Akismet.
You might also want to check out Project Honeypot. From what I can tell, it can do a lookup based on the IP address of the user, and if it is a known malicious IP, it will tell you (harvester or something like that).
Finally, you can check LinkSleeve which approaches comment spam with what it claims to be a different way. Basically, it checks the links that are being linked to in comments, and based on where the links are going to, makes a determination.
Don't forget the ultimate heuristic: The "Report Spam" button that users can click. If nothing else, this gives you as administrator a chance to update your rule base for stuff that may be slipping through. Of course, you can simply delete the offending post and user right away as well.
I have some doubts about 4° point, anyway i would also add User-Agent. It's pretty easy to fake, but in my experience, about 90% of bots are using Perl as UA
I am sure there is a webservice of some kind that you can get a list of top SEO keywords, check the content for those keywords. if the content is to rich in keywords suspect it as being spam.
