I am trying to implement a Sample application in Android which gets the malware and phishing list from safe Browsing API and checks the authenticity of URL, this is client side method, but I am constantly getting 400 (Bad Request) as response code when I am trying to hit the URL.
Searched throughout the internet but couldn't get any sample working code.
Even on Developer's Guide page https://developers.google.com/safe-browsing/developers_guide_v2 it is not mentioned how to send the list name correctly in POST request for downloading or updating.
Please help me by providing the correct procedure of how to send list name (if code snippet can be posted, it would be great as I am new to Android.)
Check out that request should end with '\n'. It is common to ignore this. I hope it helps.

I have a JSON API URL "http://myurl/getDataMethod" this takes a parameter "parameter1". How can I call this API in browser to view its result? Can I use JSFiddle to see the result on runtime? If not then can you provide code for viewing the result in Android app?
I tried calling the API in android App but I got error java.io.FileNotFoundException:, I don;t know why. Also my parameter is having # symbol which is getting converted to %40 when I call the URL through code in APP. I just want to view the data from this API by passing parameter, please help/advise. Thanks.
You can always use an API Tester tool like Postman for testing/viewing the response received from an API. Also if your API method is GET, you can even use a browser by passing the relevant query parameters.
When you try to call an API from a browser, the entire URL gets Encoded so # becomes %40
Use Postman software to access your api and its data anytime before you start coding so as to know the data structure and flow.
Refer to the Postman tutorials or official documentation to learn more about the working

Currently I'm developing android application that needs to connect itself to REST API. It is crucial for my app to access API whenever connection is possible (mobile data/wifi).
But when testing my app something extremely weird happened. Application works as expected almost all the time, but when on VipMobile operator (Austria telekom group) I cannot connect to API.
At first I didn't get it, error was too unreadable. It says
j u fehler6 the requested item could not be loaded & wrong mime type
There are a lot of unprintable chars in that message too. When i figured out that it is operator fault i tried to copy link to my API and got this.
What could that possibly be? Can anyone point me in any direction, I cannot publish application as long as there are those ridickulous errors.
This happens when the user is on 3g connection. Some mobile operators intercept clients request and if the Content-Type is not good, or not defined they display page like this. This happens also to vipmobile operator in Serbia.
Try to add right content-type to response headers on your server side.
Try to put for example Content-Type:text/plain;charset=utf-8 to headers
I am a little confused by these APIs. I am trying to integrate Google+ with my Android app and I am struggling a little. I have been successful at logging in a user using OAuth2, created a Verifier, obtained an accessToken and made a request to Google+ API.
Here is my line of code requesting to see the user information:
OAuthRequest request = new OAuthRequest(Verb.GET, "https://www.googleapis.com/plus/v1/people/me");
This successfully returns a jSON object containing my information/public.
Whenever I change the endpoint to this:
"https://www.googleapis.com/plusDomains/v1/circles/p4643b3a289c42c44"
attempting to use the PlusDomains, I get a forbidden message.
What I really want to do is manage circles for a user (simply add a page to their "Following" circle. That is all I need.
What am I doing wrong? Am I trying to use the wrong endpoint? Does Google+ API allow me to do POST requests?
Every piece of information is helpful.
Thanks in advance!
Google+API and Google+Domains API are different APIs (activating/allowing one does not activate/allow the other).
The Domains API can be considered as a more powerfull (more functionnalities) than Google+API.
See comparison of the two API here on the official doc.

I am confronting myself with a problem that I do not know how to interpret. I am doing a project using Android and Google App Engine. When I am trying to save information in Google App Engine's Big Table, directly from the servlet (hardcoded) - the save is performed with no problem. But when I am trying to save data from my Android device, the save is not performed and the log indicates Apache-HttpClient/UNAVAILABLE error. To be more specific:
405 55ms 0kb Apache-HttpClient/UNAVAILABLE (java 1.4)
82.155.246.249 - - [10/Jun/2013:05:20:59 -0700] "POST /servletnamehere HTTP/1.1" 405 306 - "Apache-HttpClient/UNAVAILABLE (java 1.4)" "appnamehere.appspot.com" ms=56 cpu_ms=21 cpm_usd=0.000034 app_engine_release=1.8.0 instance=00c61b117cede3f754aa1ece730dc88287a20199
I have seen that 405 HTTP error appears in the context of a POST method ( "405 errors often arise with the POST method. You may be trying to introduce some kind of input form on the Web site, but not all ISPs allow the POST method necessary to process the form." ) => indeed, I am trying to perform add (the object is a JPA Entity) in the database using a POST method. The data I am receiving from my Android device is serialized, through an input stream (in my case, working with JSON is not an option, these are the specifications).
Also, 306 HTTP error reffers to switch proxy. While the porevious error might be a bit intuitive, this one is beyond my student knowledge.
I have followed the instructions of this tutorial (http://trumpy.cs.elon.edu/joel/sigcse2011/), which is indeed what I need, but I really cannot figure out what I did wrong. I took again the procedure, stept by step, but I don't see the flaw.
Any help will be indeed appreciated. If I should post some code, I'll gladly do it.
Best wishes,
Cropcircles
LATER EDIT:
Now I get 417 HTTP error expectation failed. I have seen that I am supposed to set a certain parameter on false, but this workaround was available only for .NET. Is there anyone who knows what's the correspondent of the following, in Java? I am really really confused.
<system.net>
<settings>
<servicePointManager expect100Continue="false" />
</settings>
</system.net>
This is not an answer, but is too long for a comment and may be helpful, so here goes...
First, it's hard to tell what's going on here because there is limited info. Try to post more of the logging either on the client or on the server. Go to the server console and get more info, for instance, or add debugging in the client. I'd start by trying to make the POST from a debug/testing tool like hurl.it: http://www.hurl.it/ (hurl is a nice web front end to a command line HTTP client named curl, see curl itself if you want a more advanced peek). That way you can test and poke around and make SURE your server side works as you expect with a generic client. Then build other clients (like Android).
Second, "Apache-HttpClient/UNAVAILABLE" is not an error, it's just the user-agent String -- so ignore that part. (UNAVAILABLE is where the version typically is, but some impls don't have access to the version sometimes, it seems.)
Third, the 405 response code IS an error, it means POST is not allowed at the server you are trying to POST to. That can either be because POST is not allowed at all on said server, or you're violating some security policy (such as same origin).
If it's AppEngine, first check the APP you are using and make sure it supports POST (look for info on how to do POST at AppEngine to solve, for instance: google app engine: 405 method not allowed). When you say you can do it directly from a "servlet," do you mean that a POST from a different client works? (Servlet is a server side technology, so that's a little confusing.) If so then make sure your Android app is doing the client part the same way to the same host (multipart vs urlencoded, etc).
For a little more on the security stuff, which could be involved, see this post: Google App Engine + jQuery Ajax = 405 Method Not Allowed.
I've had the same trouble and in my case It was an error due to no write permission on server side area.
I was following an android test to write on a file a value transmitted in async way via POST method.
Apache received the POST request but was not able to write the data on the file due to security permission on it.
I creating an application that can teather the wifi and act as like a firewall to manage the sessions to their clients .
for example:
If i manage the clients http requests and response..after i authenticated the request ,then only the url has to be visible for them.otherwise it has to say page blocked.
In an Example provided by the google https://developers.google.com/analytics/devguides/collection/android/v2/sessions
It says it can manage sessions But I cant able to integrate it my project .Can anyone worked projects similar to this or anyone used analystics-api, help me to work on this
And how can i get the request page url from the user..
Try this example in your activity ..From this code you able manage your http requests and responses..session-handling-Exampe
Hope will help you..
