My app that is using Retrofit (v1.6.1) to connect to REST web services cannot connect to my local web server (running on localhost), this is the error I am getting.
This is inside Nexus4 (v4.3) emulator, I am using Android Studio for development and I have added android.permission.INTERNET & android.permission.ACCESS_NETWORK_STATE permissions in manifest file.
The error says its waited for 15s but it does not, it errors out right away.

On your phone connecting to localhost:3000 means "connect to port 3000 on local network interface" - which is local interface of the phone, not the port 3000 of the PC to which your phone is connected. There is nothing listening on port 3000 on the phone, so you get connection refused error.
Whould you're trying to do is (probably, hard to guess without more information) is to connect from the phone to port 3000 on you PC. So you should change the address you're connecting to from localhost to address of the PC. In case of emulator that would be 10.0.2.2 (which is localhost of the PC). See networking information for reference.
I solved the issue, need to use 10.0.2.2 instead of localhost to connect to my local server.
Found it here - http://developer.android.com/tools/devices/emulator.html#networkaddresses

I have the Crashlytics SDK installed on an Android app (through Fabric) and it was working perfectly before. All of a sudden, I'm getting ConnectionExceptions and Crashlytics cannot communicate with its remote server.
Fabric is instantiated at the end of onCreate in my Application class:
public void onCreate() {
super.onCreate();
...
Fabric.with(this, new Crashlytics());
}
Here is the stacktrace on app bootup. Any thoughts?

I think I figured out the problem. The errors only seem to happen when I'm using my local Second Cup wifi network. When I use my home network, it works just fine.
There must be some sort of proxy issue going on here.
I'm having problem with the internet permission. Yes I've looked around and I made sure the permission is outside the application tag.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="app.com.example.android.sunshine" >
<uses-permission android:name="android.permission.internet" />

Thanks for the help.
Please use:
<uses-permission android:name="android.permission.INTERNET" />
Please read here:
SecurityException: Permission denied (missing INTERNET permission?)
Depending on what you are doing you may need to add:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
Official Docs: http://developer.android.com/reference/android/Manifest.permission.html
write it like this (with caps)
<uses-permission android:name="android.permission.INTERNET" />
you can also try adding this:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
Mind the Capital-case. It is "INTERNET"
The permission in question is android.permission.INTERNET -- note that case matters.
I'm just using Ray wanderlich tutorial to create my first ever android app - a basic hello world. The app is successfully launched on the emulator and the text is displayed as expected. however i don;t like the errors in the logcat. Highly appreciate if someone helps me to identify why logcat behaving unexpectedly.

open a command prompt and type the command netstat and check whether port 5601 is open. if it is there then open another command prompt and type the following command
telnet localhost 5554
once connected
type
redir add tcp:5601:6000
and
quit
Check if it helps..
I am trying to follow this guide to get an App Engine Connected Android Project working. However, when I try to run my Android application and register, the Registration with Google Cloud Messaging succeeds, but the Registration with Endpoints Server fails.
https://developers.google.com/eclipse/docs/endpoints-androidconnected-gae
I manually set the LOCAL_ANDROID_RUN = true in CloudEndpointUtils.java
Any ideas on how I can fix this issue? I have tried the suggestions in search results with no success.
Exception received when attempting to register with server at http://10.0.2.2:8888/_ah/api/

My screen on my phone looks similar to this:
I need to download twitter profile picture of mine and show it in an imageview on click of a button. Here is my code to download the profile picture of desired user.
public static InputStream getTwitterProfilePictureOfUser(String twitterId){
try {
return new DefaultHttpClient().execute(new HttpGet("http://api.twitter.com/1/users/profile_image?user_id="+twitterId+"&size=bigger")).getEntity().getContent();
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
Getting the following exceptions. Where i'am going wrong ?
