I'm looking for a solution similar to the iPhone Facebook Connect (https://github.com/facebook/facebook-ios-sdk) for the BlackBerry platform. Basically, I need my users to authenticate against Facebook from within a native BlackBerry application (so, not a Web based mobile application). Is there a library I could use, and if not, what will be the correct approach to achieve this?
Thanks in advance!
Options for BlackBerry are:
Use Facebook Platform for Mobile
Use REST API approach provided by Eki Y. Baskoro
Try to port JavaFB from J2SE to J2ME
I managed to go through Facebook Connect authentication within my BB app. After cracking my head for three days I realised that it is the URL that is the culprit!
Basically these are what you need (assuming you are developing for 4.5 platform):
Using Browser Field, do a POST to http://m.facebook.com/login.php (the mobile version of Facebook) passing all the necessary arguments as per the Desktop application counterparts (one challenge is to get the signature generation correct).
Once the User successfully grants access, capture the URL of the success screen. You will obtain your auth_token.
Do a POST to the REST server to obtain the session key and secret given the auth_token you obtain.
Save the returned session key and secret, persist it, and wholla! your app is up and running.
I am developing a custom LoginScreen and FacebookFacade object to incorporate the first three steps above, if anyone is ever interested to reuse my code. It'll be GPLed, I suppose ;)
Afzal, I had a similar problem and I've found out that I actually had a problem with my connection string. You can look at the following link there is some explanation and code for creating the correct connection string
http://www.localytics.com/blog/post/how-to-reliably-establish-a-network-connection-on-any-blackberry-device/
and just add the connection string to the FetchThread where it opens the connection:
connection = (HttpConnection)Connector.open(absoluteUrl+getConnectionString());

I am writing an iOS app and have a dilemma. The app will be used to test the BLE protocol of devices coming off our production line. It needs to be very simple, It is a one button app that automatically connects to devices and tests commands in our protocol and gives a pass or fail result. If it passes the device id is sent to our API to be entered in our database.
My problem is I don't want the user to have to login, but I need to send a username and password to the API to log in. This means the username and password has to be included in the app. I am trying to find out the most secure way to do this. I initially thought I would include a plist in the app with the credentials, enter them in keychain, then delete the plist. However I don't believe you can delete a file included in the app bundle (I get a 513 permission error).
I have 2 questions. Is it secure to include credentials in code? Is there a better way to do this?
Thanks!
No.
Use API to retrieve credentials and store to keychain. Simple call to firebase could solve this. Or use your own backend with your custom “security”.
But even obtaining via API don’t give you 100% security. Everything depends. API solution gives you flexibility and ability to support different versions with different credentials.
Our iphone app allows for sign in via Foursquare via oauth. It was working fine and recently stopped working.
The error we get is: Connecting Failure: Callback uri is not valid for this consumer.
HOWEVER, if the user does not have the foursquare app installed on their phone it works fine as before. It seems as if FS is now doing a redirect to handle the oauth inside the FS app and this fails when attempting to return to the originating application. Via safari it seems to work.
This is on ios 9.
Solutions?? Thanks!
We've changed to use a SafariViewController and this seems to force Foursquare to not to this strange in-app redirect, solving the issue. This is also Apple's preferred oauth method, so probably the way to go.
Still seems like a problem on the Foursquare side that they may want to address for others however. I'm closing this question. Thanks.
Where does your redirect URL point? If you want it to launch your app after completion you should point to the iTunes store (pre-iOS9) link for your app or the universal link (iOS9 onwards).
More information on redirects for the native foursquare app is available in the README here: https://github.com/foursquare/foursquare-ios-oauth/
How to create a universal link in iOS9 https://www.appsflyer.com/blog/how-to-set-up-ios-9-universal-links-for-your-app/
A callback url is a webpage loaded after your web app has been
verified. In this case, you need to specify a page for to send data to
after authentication
Double check your Foursquare credentials and update the callback uri to a valid link. Tutorial link
Please follow the below points, may be one resolves your issue:-
Enter the callback in foursquare account in addcallback methods. Then in your code add the call back to the provider before you authorize. (Reference here).
You're getting that error because the URL you're pointing your users to (foursquare.com/oauth2/...) includes a redirect_uri parameter that doesn't match with what you configured in your app's settings under https://foursquare.com/developers/apps. Make sure these match!
I'm developing an app using Phonegap and it implements a Facebook login to save some data using the user_id as a reference. I'm using OAuth.io library to implement the login dialog and everything runs smoothly in the web browser and in Android but when I test the app in XCode and I tap the login button the following error appears.
Cannot find hostname in file:/// from static
code: InvalidHeader
message: Cannot find hostname in file:/// from static
My guess is that it has something to do with phonegap not making an external request since the app is not actually hosted in a domain but running locally... any thoughts?
Seems like you are using oauth.js library instead of phonegap version
In your main page "index.html" add reference to the correct js file
<script src="oauth-phonegap.js"></script>
Then follow the instructions here to build your application
I had a simular issue using oauth.io. Turns out it was my Ajax prefilter changing the REQUEST to Facebook(it was adding parameters to the header for each request). Wether this is your issue or not, what you need to do is compare a successful REQUEST to Facebook to an unseccussful one, that will show you where things go wrong. Alternativly a blank phonegap app with no extra code other then the required oauth code should work and will be a Good starting point to isolate your issue.
I have been using Phonegap 2 years before.Though I didn't connect to facebook before,I connected to other website by OAuth.I can show you my solution.
Firstly,you should know how OAuth works.You can read OAuth 2.0 from facebook developer website or other websites.
Secondly,you should know your target:token,uid,expires_time.The most important thing is token.
Thirdly,just do it.In 2010,I solve this problem by using Phonegap Childbrowser plugin(now Phonegap have a inAppBrowser) and a light server.
Why I should use a light server?The server can help me to handle the redirecting in OAuth service and do cache.
Step 1 : I wrote script to connect with my server,and my server connect to OAuth Service(facebook).
Step 2 : OAuth Service(Facebook) do response and redirect to Facebook login page.
Step 3 : After input username and password,OAuth Service(Facebook) will redirect to another url and do a callback with some code or token.
Step 4 : If you get the token,save it and use it to connect OAuth Service(Facebook) if you want.
When I saw "Cannot find hostname in file:/// from static " in your description,I know that maybe you get confuse in OAuth.Now,I suggest you some server side code to handle it and make your OAuth process possible.
I have a website that users can log into to see their account info.
I would like to build functionality into my iOS app that allows them to log in and see their info in the app. The usernames and passwords are stored in a SQL database.
How can I authenticate the username and password the user types into the app with the database?
If you have better atuthentication system in your web..
then i would prefer you to use the WEBVIEW for your login page. and continues the other using the normal app flow.
there are lot of tutorials for creating username and password login Function in IOS. i dont know whther you are basic or new progrmmer. But try this you may get some idea.

You can go with JSON serialisation, if you experienced to load data from server.
There are multiple ways you can go about this but at the end of the day you need an endpoint for your iOS application to talk to your web server. This can be done with a TCP connection (little more complicated) or with a RESTful HTTP API endpoint which is generally the way most developers will go.
To get you running up and quickly on the client side have a look at AFNetworking to do the heavy lifting on your HTTP requests. You will then need a URL on your website that the iOS application can query. Abstract things to keep your API on a different subdomain, say for instance by creating a subdomain to handle your API requests. A login example could look like this
http://api.mysite.com/login
For a PHP based REST API here is a tutorial for you, PHP API or you could use a Node.js framework such as Restify
The general practise is to use JSON encoded data when sending requests back and forth from the server, iOS 7 has built in JSON encoding/decoding, node and PHP also have pretty good support.
Once you are able to send and receive HTTP request from your iOS device to your web server it is just a matter of checking the username and password match up on the server side (seems you already know how to do this?) to the ones in your database and sending back a authentication BOOL and option error message if failed.
I need to use Twitter Oauth to login my windows phone app,
What i need exactly is
1)when the user click twitter log in button from my app, i need to show the twitter llog in page in a browser,
2)when he enters his credentials and accept the app, then i should get the user information like, name, gender, bday, what ever i can take.
That,s it, then i can close the browser and make my app active.
I just need to make the user to log in via twitter.
I referred lot of examples, that are all quit confusing and doing all the stuffs in twiiter.
I tried this example
and got this error
'TweetSharp.TwitterService' does not contain a definition fError 2 'TweetSharp.TwitterService' does not contain a definition for 'GetAccessToken' and no extension method 'GetAccessToken' accepting a first argument of type 'TweetSharp.TwitterService' could be found (are you missing a using directive or an assembly reference?)
and i tried enter link description here
failed on that too.
Can anybody help me to do the authentication via twitter for my app.
Thank you.
I tried this example and got success, I contacted the person who have posted that example and got help from him to solve the issues raised from this example.
Actually this Example works fine for twitter integration,
What you have to do is
1)Register your app in twitter, here the link for app registration,
log in and register your app.
2)Make sure you have given the Call Back URL(i forget to give that, and that makes me face lot of issues)
3)Note down the Consumer Key, Consumer Secret and Call back url(we need specify this 3 in our code)
4)Go to Settings, and set your app access to Read and Write
5)down load the above link and change the Consumer Key, Consumer Secret and Call back url as per your app, and then run the example, it will work fine.
Thank you.
If you just want to authenticate using Twitter and don't want to post anything, perhaps you can try Azure Mobile Service Authentication. You can find more information here: mobile services authentication
