I would like to connect a Java application to the Nest-Cloud via the Firebase-Api. The application is as simple as reading the setpoint of a nest thermostat.
I spent a lot of time on developer.nest.com and firebase.com to find the required information, but failed.
What is actually the base url, where the firebase is located? seems not to be home.nest.com
How can I authenticate without user interaction? I tried FirebaseSimpleLogin, but the implementation depens on Android, which is not my platform.
Thanks for your help.
For 1) I don't know for sure, but have you tried https://api.home.nest.com and https://developer-api.nest.com?
2) The user has to authenticate and allow the client you're developing at least once. You'll need to get an authorization code, which you get from the client page on the Nest developer site. The code is six characters I think, and you'll have to include that in your code or assign to a variable and call it.
Take a look at another entry I made. If nothing else, it might help you get a little farther down your rabbit trail.

I have a personal access token for my Github account that I am trying to use to test an app that has to have the functionality of following/unfollowing other users. The problem for me, I am having a really hard time figuring out how I am even supposed to use my token or how to go about doing it.
I know from multiple other posts that you follow others with a PUT request on the Github API (which I can do with http requests in java), but the prerequisite is that you are already authenticated. In the documentation on Github, they use curl on a command line interface (https://developer.github.com/v3/#authentication), but that is not what I am wanting to do.
I am just generally lost as to what I should be looking for on how to go about doing this right now. Any help is appreciated. Thanks!
I want to create an app for a website that I don't own, like youtube or reddit. Every time I search for help, all I keep getting is how to create a webview. I've done that but that's not what I want. I want to take the website's content and create an app with it, like create my own buttons and such. I want to convert a website into an app.
I was thinking of somehow loading the website in the background and creating activities/buttons/intents that basically do what the webpage does but I don't know how to go about that or if there's a better way.
Thank you in advance.
Please let me know if clarification is needed.
Alright i got -3 votes for some reason and it has been 12 hours since i posted this question, i'm guessing the question has been consumed by the abyss of questions by now.
I made a reddit post and got some responses:
one user:
The term you’re looking for is “web scraping“ or “site scraping”. I think that’s probably what you need to research before you’re ready to handle how to make that into an app.
That’s a good starting point and once you have the content from scraping, making the app is no different than any other app.
second user:
If the website has a public (or private) API, you can use your buttons and networking calls to their API to build your client app. You are building a "YouTube client" in this case using the YouTube API.
If they dont have an API and you don't want to display their website, what you are doing is trying to reverse engineer their website and hijack the UI which is not a good practice and may even be illegal depending on the site and terms.
third user:
#second user is right on the money, but one thing I'll like to add is, the goal is to get data off of the website so that you can use in your app. An API is one (convenient) way of doing that but others are,
RSS or similar feed content (prefer this if there website supports)
HTML scraping
The above two will require you store the data somewhere else (and possible expose an API instead) because of technical reasons: you don't have access to older entries in RSS feeds and it's atrocious to keep on scraping everytime you need to access the website data. They can be done on the client (mobile app) but are best done on a server. This means you might need to get your hands dirty writing server code but you don't have to.
/thread
I'm going to do research on website scrapping and APIs to see which route i should go.
Hopefully this helped someone else.
Well, I'm kinda new to mobile app development, but I have a fair amount of experience with Java. I stumbled upon CodeNameOne and thought I'd try to make an app based on "It's Learning". Unfortunately this site won't let me get straight to the logon page without going through the main portal first. So here's my question:
Is there any way (in CodeNameOne) to automate navigation on the web in the background and get information from the site, such as login and the newsfeed, then send data from the app and to the web page?
(Something like the way HtmlUnit works is what I'm looking for)
You can do some of that work using ConnectionRequest to simulate user interaction but that would probably be fragile as Andrew mentioned. The main issue is that they might change the site structure and your HtmlUnit code would break.
What we do when faced with such a situation is create a server that abstracts the "scraping" behind a set of clearly defined REST API's. That way if the site design changes we just update the server to match the change and all the clients out there will work as usual without requiring an update.
Naturally there is always a possibility of the site blocking you or even blocking your server IP address/range so Andrews advice of actually talking to the guys is sound advice.
I'm starting a new project. It consists of:
Java desktop application downloadable from the internet with a client database.
PHP website on the internet with a server database.
The user who downloaded the app will use it to add items (not important what are they now) to the local database offline. When/If he is online, the item will be added to the server database so other connected users (through the desktop app or through the website) will see it.
I googled the issue and found it's more complected than I guess. One of the solution is to use some ready tools like SymmetricDS and Daffodil to gain in term of security, performance and scalability, but they're difficult to configure and install in both client and server side, and need the access to command prompt which requires me to pass to a dedicated host (well, that is not a real problem). Also, all what I want is just what I've described, not all what these tools actually provide.
Can I achieve that by myself within my Java application and maybe with the help of
the web server PHP?
I'm using MySQL for the info.
Edit: what really matters is to send items to the server database. Reading it can be less tricky using RSS Feed reading, for example.
Basically, you can use HTTP/HTTPS API. When a user online, send items to your php file and mark the items "sended" at local database. But you have to control edited or deleted statuses. So, yes that is much complicated but a solution.
Well the easiest solution that comes to my mind would be to save for each item a last edit date (on the server as well as on the client). Additionaly you have to keep track when a client got his last update from the server.
So whenever a client goes online the server sends him all updates.
But for that you have to make sure that the time on the client and the server are the same, and it doesn't solve the problem what happens if two clients edit the same item.
CouchDB solves the distributed synchronization problem very nicely, but it is a NoSQL DB. Depending on what your application should do, using it would boil down to using instances of CouchDB both locally inside very application, and on the central server.
You'd have to deal with conflicts nevertheless. The only thing CouchDB will support you with is easier detection of conflicts, and the data of both conflicting edits, so your application can work it out either automatically, or with user help.
On the other hand, generatin a unique id on the central server can be as easy as adding the creating user's id to each item id.
I need to add a functionality to my java-based web application that will allow users to click on a link and the application will automatically call the user and another party and connect them in a phone call.
Does anybody know what would this entail?
Thanks
It can be done with Twilio, and their new, easy Conferencing API. Trust me, it's really really simple. Another option might be CloudVox, but I haven't (formally) tried their service yet.
The World-Wide Web Consortium has an integrated set of speech interaction standards that you'll find interesting. There's a markup language called VoiceXML that is analogous to HTML in that web applications generate it. It differs from HTML in that it's specialized for temporally-based speech interactions instead of visual interactions. So instead of looking at a screen you listen to audio prompts and computer-generated speech. Instead of typing and mousing, you speak back and what you say is processed by a speech recognizer or recorded.
There are many companies using VoiceXML to automate voice response systems, and they handle billions of calls per year. You've probably talked to them many times without realizing it. One of the best companies in this space is Voxeo, and they have a developer site at http://evolution.voxeo.com/ that you can play with. Evolution lets you call your web application over an ordinary phone (or Skype). You actually talk to a VoiceXML-based web browser which will fetch a VoiceXML page from your Java application server, "play" it to you, listen to what you say, and then report that back to your app via a form submission, get the next page to render to you, etc.
Another related standard is CCXML, or Call Control XML. You use this to create teleconferences that may or may not include a voice response application.
So it sounds like in your case you want your standard web application to talk to a CCXML server and ask it establish call legs to the web user and to a customer service line. I know that Voxeo Evolution offers CCXML as well.
There are other good companies in this space too. One that comes to mind is TellMe, which was bought by Microsoft a year or two ago. These two companies (and others) offer professional services too.
So I wanted to write this up as an answer to the comment above. The Skype API provides a number of options for telephony in COM, Java and Python:
Skype4Java - https://developer.skype.com/wiki/Java_API
Skype4Py - https://developer.skype.com/wiki/Skype4Py
Skype4COM - https://developer.skype.com/Docs/Skype4COM
They provide a communication and command protocol layer for working with Skype, more info on the API here:

It's kind of different for every platform, the Linux version is based on DBus or X11.
Try FreeSWITCH. I have done this before. Its pretty straight forward. Can be a bit hairy when you need to log call accounting and all those stuff. I hopefully would be able to provide you some guidelines and code samples, let me get home first. Cheers.
The good thing in using FreeSWITCH, you will be able to handle multiple calls, and quite a number of. You might need that in future.
Note: You have to use some kind of VoIP provider in order to do that. I was using Gizmo5 that time and it was pretty good.
Sorry buddy, lost the servlet code somewhere. But no worries it was a simple servlet. Fortunately, I had added my example Java code for XML-RPC, into the FreeSWITCH wiki, and actually that was the code my servlet was invoking down the road. Below is the snippet.
XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
XmlRpcClient client = new XmlRpcClient();
try {
config.setServerURL(new URL("http://localhost:8080/RPC2"));
config.setBasicUserName("freeswitch");
config.setBasicPassword("works");
client.setConfig(config);
// For external phone calls using VoIP. We will use something like below.
// new Object[]{"originate", "sofia/gateway/gizmo1/6098989898 &bridge(sofia/gateway/gizmo9/0116054545454)"}
// gizmo1, and gizmo9 are the accounts configured under freeswitch gateway configuration.
client.execute("freeswitch.api", new Object[]{"originate", "sofia/internal/1001 &park()"});
} catch (Exception ex) {
ex.printStackTrace();
}
Moreover, you need to configure few things prior doing this. You need to set up the gateway using your VoIP provider settings.
For FreeSWITCH related help, take a look at this SO Thread.
I know of 2 API providers that does what you need:
1) twilio - can connect to 2 or more parties using TwiML (their markup). example
2) Hoiio - very easy to use with 1 line of RESTful api call. example
