java.net.UnknownHostException: Unable to resolve host [LOCAL]

I use the INTERNET uses-permission in the manifest file.
If I type URL url = new URL('http://www.example.com/page') (remote server) it will work.
But if I type URL url = new URL('http://example.local/page') (local server) it will return the error
java.net.UnknownHostException: Unable to resolve host "example.local": No address associated with hostname
Now in %WINDIR%/System32/drivers/etc/hosts I wrote this entry :
10.101.0.179 example.local
I can't use new URL('http://10.101.0.179/page') because example.local is a virtualHost in my apache configuration.
Can't my AVD looks into the hosts file ? what should I do to tell android to fetch the ip 10.101.0.179 but still send a proper information to apache and tell it to serve the virtual host example.local ?

If you try to request a web-page from your local HTTP server and the page is bounded to a virtualHost, so let say you need to reach http://example.local/mypage and if as pointed by #CommonsWare you don't use mDNS to resolve inter-local domain-names, android will probably throw the same error message as it reads in the title of this question. Here's the solution I am using :
let's say http://example.local/mypage refers to the ip address 10.101.0.179, Android won't be able to resolve example.local, you need to write the raw url (of your actual local server)
try {
...
URL url = new URL("http://10.101.0.179/mypage");
HttpUrlConnection conn = (HttpUrlConnection) url.openConnection();
...
}
...
But now when Apache receives this request, unless serving your desired host, 10.101.0.179 won't be understood in case of a VirtualHost. To round-about this problem, just modify the Host http-header property using setRequestProperty :
...
conn.setRequestProperty("Host", "example.local");
...
And it should work.

First you must check if you have given INTERNET permission in your manifest file or not, second you make sure that your emulator or computer has a valid internet. If it doesn't work than you can do following:
If you are using localhost url than you must convert that url into IP address to work with App specially using Android emulator.
For example :
My Current url is
http://mylocaladdress:9090/myapp.svc/ForgetPassword?EmailID=test#test.com
Now you can put the following command into terminal on mac or you can use cmd on windows
ping mylocaladdress
The result will give u the IP address and my final url becomes
http://10.1.2.111:9090/myapp.svc/ForgetPassword?EmailID=test#test.com
This url worked perfectly in android emulator without exception.

LoopJ AndroidAsyncHttp redirect not working

I have an android application where I have authentication and authorization services. Recently we had to change our URL's from http to https. I really don't want to resubmit app to the app store with urls changed to https.
Main problem I am facing is, asynchttpclient returning status code 200 without response, why I am not getting 301 which I am getting when I try to call service through advanced rest client.
I tried this already:
aesHttpClient.getHttpClient().getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, false);
I want to know how can I redirect in asynchttpclient?
Please help

AsyncHttpClient client = new AsyncHttpClient()；
client.setEnableRedirects(true);

Post an image from Android client to Rails server without triggering InvalidAuthenticityToken

I'm building an Android app that runs off of a rails server. At first, when I tried to post simple String data to the server, I ran into an InvalidAuthenticityToken issue, but realized that I can bypass the authentication by setting the content type to "json"
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(Constants.REST_HOST + "/add_comment");
post.addHeader("Content-Type", "application/json");
The next step was trying to get upload profile picture working. However, when I tried uploading a photo via a MultipartEntity post, setting the content type to "json" causes the following error
StandardError (Invalid JSON string):
but not setting the content type brings back the InvalidAuthenticityToken exception. What's the correct way to post an image to a rails server from a foreign Java client?
ActionController::InvalidAuthenticityToken
(ActionController::InvalidAuthenticityToken):

Based on Jesse's suggestion, I ended up using
protect_from_forgery :except => :upload_avatar_pic
to disable authenticity check, but only for a specific function, so checks for browser requests are still validated.

You can disable authenticity checking on API non-get calls from non-web clients. You can do this in a before filter
class ApiController < ApplicationController
skip_before_filter :verify_authenticity_token
def create
#or whatever
end
end

The problem solved by Jesse Wolgamott said, but the page show "You are being redirected" message when I submit the form (Update,create,show). In before that the page redirected correctly. I am using rails 2.3.8.how to resolve this?
