I have a problem with using Volley. I'm trying to send request to site http://lawbite_api.codebnb.me but results differ from phone to phone (depends on Android version). For some reason on Android 6 all OK, but on Android 4.4 I'm getting java.net.UnknownHostException.
Here is stacktrace:

The simple answer is to not use an underscore in the subdomain part of the hostname. It's probably something to do with the hostname rules in Android 4.4 (and probably lower).
I don't think url will change as per API level in Volley. I have already use same URL for all devices with API greater than Android 4.4 and there is no issue regarding to URL there is something else. Please provide Volley request code

There are following possibility to occur this issue
maybe your project or file location is not perfect
maybe because of the port number or IP not match time of calling
First, try to run this page in your mobile browser web browser and it will work in mobile browser then it will work in API definitely if not work then you need to change in your config
Bumped into an issue where my application using https://github.com/square/okhttp - okhttp version - 3.12.1 is not able to connect to a domain even though I've provided the Internet Permission in the AndroidManifest.xml
The user was, however, able to connect to the internet on their device and use other apps, based on their review comments.
For now, I am unable to reproduce the exception and hence if anyone who has experienced this issue before could help me understand better.
I cannot upgrade the library at the moment as I don't want to introduce a big change.

I usally have that error using Retrofit (with Okhttp as client), it happens when the device doesn't have any internet conection (both WIFI or mobile data) or my server endpoint is down. Try it yourself! But there are several factors else; like runtime request permisions or the network security config.
Hope this helps, bro.
We solved this issue by making a few DNS changes.
Reduced few CNAME records.
Reduced TTL.
No code changes were made on the android client.
Maybe, the divice use to get API don't have internet.Please connect internet and try again!
I have developed an Android application using which the user can upload large files (~1 to 2 GB in size) to his/her Google Drive account.
I am using the Google Drive Rest API for Android. Sometimes, the upload operation fails with following exception:

I have following questions:
What are the reasons for such error?
Is this the issue related to network speed?
Is this is the problem with Google Drive API? If yes, how to avoid this error?
I testing the app with Android 7.0.
I would appreciate any suggestions and thoughts on this topic. Thank you.
I'm making an app for Android 4.4 and above, and I'm trying to do an https request, I first tried with Retrofit and it gives me this:
V/error: javax.net.ssl.SSLHandshakeException: Handshake failed
I thoug it was something about the Retrofit API, but later I tried with Volley and it gives me this:
SSL handshake aborted: ssl=0xf311e9c8: Failure in SSL library, usually a protocol error

In fact, is the same issue, I don't know if I need add something to my app, due this request works perfectly with postman.
The weird thing is, before we migrate the services to the new server, I was working with a server with HTTP and it works perfectly. I don't know what I must add about security to my app.
I am using retrofit-beta2 and i get the below crash from time to time. Am not sure what am i doing wrong. It would be great if someone could give me a hint on fixing the problem.

As said in this issue there is two possibilities:
OkHttp has a bug where we’re attempting to recover when we shouldn't
be because we’ve exhausted all of the available routes.
OkHttp has a bug where you’ve got a custom DNS implementation that
returned zero IP addresses for a host and we didn't reject that.
My suggestion is to use new versions of retrofit and okhttp, because Retrofit 2 is already in release.
compile 'com.squareup.okhttp3:okhttp:3.1.2'
compile 'com.squareup.retrofit2:retrofit:2.0.0'
