Authenticating the application in embedded systems - Google Drive SDK - google-drive-api

Is there any way to authenticate the application to use the Google Drive API without a native browser in an embedded system?
I'm looking for a solution to the user accepts and put your password and username using the OAuth2.0 without browser interactions... Is it possible?
My applications is build in Java Code.
Thanks in advance.

I am presently trying to do just this and I don't think it is possible because:
To authenticate in embedded device you need to use this process:
https://developers.google.com/accounts/docs/OAuth2ForDevices
the problem with this, is that it only accept limited range of scopes like:
--https://www.googleapis.com/auth/userinfo.profile
which works OK
but when you try with scope like:
--https://www.googleapis.com/auth/drive.*
you get invalid_scope.
If you find a solution please let me know, I have the same problem my device is embedded, has no screen, and is not available with remote desktop of the like.
thanks for any feed back.

Use the OAuth 2 device flow which is designed for cases where a browser isn't available on the device. It allows the user to complete the login & authorization on a separate, more capable device (phone/tablet/laptop) where a browser is available.

Tail like logging window for my web app?

I am developing an app using Phalcon and would like to create a popup logging window that displays any logging type information when I am logged in (such as DB calls and exceptions).
Alot of my app is driven by Ajax calls. Is it going to be possible to have a window that I can popup on my main app that uses a tail like method of displaying this information?
How would I go about this? I'm not entirely sure that what I want is possible with the Ajax calls as they are done in a different request. I can't find anything on the internet as to how I would go about this so any help would be great.
Well, you didn't said that explicitly, but I imagine that you want this just for development purposes. If so, you can log useful info to a method that checks if it should send that log to the browser based on some criteria (e.g. logged in user is you, the app is in a dev enviroment, etc) and then use Phalcon's FirePHP log adapter to send to log the information to the browser.
You'll just need to have some FirePHP extension in your Firefox or Chrome to be able to see the information under your JavaScript console. And yes, it works well with Ajax calls too.
Let me know if you need further explanations on this...
I think you are looking for a debug toolkit.. There are lot of toolkit available on packagist.org and phalconist.com. I personally like this phalcon-debug-widget toolkit that you may try.

HTML5 based cross platform mobile app?

Here My question is that i want to create one html5 based cross platform mobile application.
In which i want to read my gmail mail data and want to display it in my application page.
Here i don't want to send any mail using this app i just want to display the mail of my gmail account.I searched about it on google but i did not get any result for it.
if we make something like it then give me some information about it how to read data from gmail mail.If we can't do then please give me some reason for it or helpful links.
So if anyone have any idea about it then please help me.
Thanks in advance !..
Pure HTML 5 Alone
No. As the other answers point out, Gmail does not provide a RESTfull API that would be accessible to a HTML mobile app. However, Gmail does provide the standard IMAP and SMTP APIs. You can read all about integrating GMail features within apps here: https://developers.google.com/gmail/.
Pure HTML 5 With Middleware
Using pure mobile HTML5 cross platform code - you will not be able to make use of these APIs. However, you could write a server to act as a middleware between GMail and your pure HTML 5 application. The server could do all the interaction needed with Gmail, and your application could interface with the server. I'm not recommending this because you could be opening up your user's Gmail to many security flaws, and it would be a lot of extra work on top of the HTML5 app - but it is possible.
Mobile Chrome App
Although this is not pure HTML5 - Chrome Apps allow TCP socket connections. Having direct TCP connections would allow you to write - or find an existing - IMAP client to read email. Next, you could use Mobile Chrome Apps to put your chrome app on IOS and Android. This is not pure HTML5 and is not 100% cross platform (windows phone, etc), but you app would be able to directly talk to Gmail.
Platform Specific Apps
Of course the final option is to write platform-specific apps that can directly interface with IMAP & SMTP. This option does go directly against your requirements in the question, but I felt like it should be included to be a comprehensive answer.
Sorry, but you cannot create such Html5 based cross platform mobile app
(which seems like an email client, though used for reading purpose only). Google hasn't provided any Rest API through which we can access our gmail accounts. Link provided by #tnt, itself says in its last line:
Please keep in mind that Gmail messages will appear in your aggregator only if there are unread messages in your inbox.
You can even check the list of APIs provided by google: APIs Explorer
You can add a middleware (server) like:
Your application <--> Your server <--> Gmail
For this, you should have a server.
Create RESTful web services (using, WCF, for example) that will do your job of bring mails to you. Publish it. And, you can, then, use those service urls in your html pages. This the way you can achieve, what you want (making cross platform mail clients, I guess)..
My suggestion is to go with phonegap.I used it in which u can create apps in HTML5.Also since for gmail use gmail apis in html5.
The following link is for phonegap

Is it possible to do OAuth on WP8 without embeded browser?

This is for doing OAuth with the Pocket API, it specifically states that using an embedded webview is a violation of the terms of use, all OAuth examples I can find on WP8 seem to rely on the embedded webbrowser to do the authentication.
Is it not possible to use the default browser in WP8 to do the authentication and then redirect back into the App? I have done this in Android before. Thanks.
Well, if you read their documentation, it says that you need to provide a redirect URL. I am not sure if it will work, but you could try adding URI association to your application and specify callback URL that will return back to your app.
Then, when your application is reactivated from the default browser, you should know that the user has authorized it.
Thus you could use WebBrowserTask for that, but I am unaware if you can call local app-URI from browser.

Activate chrome app from web page?

I am building a packaged chrome app (It is needed as I want to access chrome.socket). I have a website from which I would like to call my app (if installed or ask the user to install it) by clicking a link. Is this possible ? Not able to find any easy way for this workflow.
The url_handlers might be the best way to achieve this.
You can also use the externally_connectable manifest property to declare that your website can connect to your app, then call chrome.runtime.sendMessage or chrome.runtime.connect from your webpage and handle it in an chrome.runtime.onMessage handler in the app.
Which one is better suited depends on your needs. The url_handlers is an easier way, but it will permanently assign the URL on your link to your app, so you won't be able to use it for anything else if the app is installed. The externally_connectable is a harder way, but it enables a much more elaborate bidirectional communication between your website and the app.
You can even use a combination of the two approaches, if you need: launch the app using the url_handlers feature, then establish a communication channel back to the website once the app is up and running.
Apps can now (as of Chrome 31 I believe) register to handle urls by adding url_handlers in their manifest and detecting the url causing the app to launch in the chrome.app.runtime.onLaunched event. If the app doesn't launch, your hosted web site will be loaded an can present an inline installation with chrome.webstore.install.

Authentication with Box on iPad

I'm adding Box support to an iPad app. I tried the official SDK and I don't want to use it for the following reasons:
Login page is too wide for a modal controller with UIModalPresentationFormSheet style on iPad. The SDK hosts UIWebView which loads content of https://m.box.net/api/1.0/auth/, which perhaps returns HTML with min width set to 768px (although I didn't check the HTML, speculating here).
HTML in login page doesn't show Google Apps authentication option. The full desktop version of the page does.
Because the login page is hosted in UIWebView the user cannot be sure that he's supplying the credentials to Box, and not to an app author.
I don't need the whole SDK functionality, just authentication, folder/file listing and content download. Since my app also uses other cloud storage providers I'd prefer to provide uniform file browsing experience.
Here's what I'm going to do:
Add a custom URL scheme for my app, let's say "myapp".
In Box's Application settings for my app set Redirect URL to myapp://RedirFromBoxAuth.
When the user chooses to browse Box from inside my app, I'm going to:
Get a ticket by calling GET https://www.box.com/api/1.0/rest?action=get_ticket&api_key={API_KEY}
Extract the ticket, then call openUrl with https://www.box.com/api/1.0/auth/{TICKET} This will open Safari and let the user enter his credentials. This is the full, desktop version of the login page.
On successful login Box's server will tell Safari to redirect to myapp://RedirFromBoxAuth?ticket={TICKET}&auth_token={TOKEN}, which in turn will tell iOS to yield control to my app.
My app receives handleOpenURL notification and I can extract the authentication token and use REST API from now on.
Please comment, is it a good plan? I created a quick prototype and it seems to work, but maybe I'm missing something?
Box team, could you please tell us will an app using this authentication model be eligible for inclusion in OneCloud?
This seems like a good strategy and will probably make for a better UX/easier implementation than the normal redirect. Please let us know if you run into any weird edge cases by implementing it this way.
