Android Studio - Genymotion - Volley gets wrong url to download

I'm facing this really strange issue and I couldn't realize what's happening.
I have a login activity and when I try to make a request to validate the user information, I get this error in volley:
com.android.volley.NoConnectionError: java.net.UnknownHostException: Unable to resolve host "teste.escolaemmovimento.com.br": No address associated with hostname.
This error only happens when I'm using the Genymotion emulator, I verify the URL field inside of the volley Request object right after create that and after insert the request in the volley queue and the correct url is there.
(when I test in the device this error does not happens.)

Anyone has already faced this issue? This is a problem only associate with the emulator? Thanks for any help.

UnknownHostException is thrown to indicate that the IP address of a host could not be determined. Make sure you have internet access inside of Genymotion.

Android - Cordova 3.5.0 deviceready not firing after installing media plugin

This is interesting and weird issue.
First I created Cordova project locally. I'm not using Bd.
using
cordova create test com.test.project.story "Test"
Which worked successfully!
Then I added android platform, using
cordova platform add android
Worked successfully.
Then I built the project using
cordova build
Worked, again.
I opened the project from Eclipse and ran it on emulator.
Worked properly.
Then I thought of adding some plugins in my project using
cordova plugin add org.apache.cordova.file
cordova plugin add org.apache.cordova.media
Removed the android platform and added the platform again. Then built and ran the project on emulator.
The screen was stuck on Connecting to device forever.
I rechecked if I was using the correct cordova.js for android platform.
It is correct, and it says
// Platform: android
// 3.5.0
Checked ADB log and there are a lot of suspicious things going on.

What's going on here?
UPDATE:
Works fine on iOS.

I ran into the same issue.
What worked for me was using a different version of the File plugin found here:
https://github.com/onflapp/cordova-plugin-file
Related topic: Cordova File plugin never becomes ready in Android

for me it got solved by adding cordova.js in index.html( though its not required in ripple)
<script src="cordova.js"></script>

I ran into the same and resolved using apache official dev build File plugin:
https://github.com/apache/cordova-plugin-file/
Funny enough cordova release 1.3.1-dev is more stable then official release 1.2.0 ...

By now a newer version of the file plugin has been released. You should no longer experience the issue with the updated version (and there is thus no longer a need to downgrade).

I had a similar issue. deviceReady event was not firing (ionic app on android). Worked after I removed the file plugin v1.2 and then added v1.1 instead.

Sqlite: cannot open file at line

This error happened occasionally when I did some user/stress test on Android. Files under /data disapppeared and system server crashed after this error occurred. I am curious about the name of database "contacts2.db-mj7742599A4". Normally it should be contacts2.db. What does "*.db-mj7742599A4" mean? Anyone can help please?

Android Hello World app crashes: IllegalArgumentException from Surface.lockCanvasNative

I am trying to run the simplest Hello World example app and looks like I can crash it even all it does is showing a TextView.
Steps to reproduce: Launch it in the emulator (1.5). Open the app - it shows the text view, then lock the phone by pressing "end call" button. Unlock by pressing "menu", then press "back". App crashes with "The process android.process.acore has stopped unexpectedly..." and Force Close button. It does not happen all the time, but I am able to reproduce it every time after wiping the user data at least.
I wonder if default Hello World is missing a detail which was considered too advanced for a hello world... Such problems with a basic example does not look very encouraging =)
Any idea what detail is missing and how to avoid this crash?

sounds to me more like something wrong with your emulator. Why dont you delete your emulator and create a new one and try again with a fresh project.
Hope that will help you. BTW why are you using emulator on 1.5?? Start to build applications for min 2.1.
Good luck.
