AsyncHttpClient by Callum Taylor
Follow me on Twitter | Website
This is the new and improved version of AsyncHttpClient
taken from X-Library. It was long due a re-write.
In this version it allows a more flexible usage of posting files, http entities and GZIP handling.
The library uses Square's OKHTTP library.
It consists of 2 different classes, AsyncHttpClient
and SyncHttpClient
. Obviously by the name, AsyncHttpClient
is for asynchronous requests which uses the AsyncTask
paradigm, and SyncHttpClient
is for synchronous requests which should be handled by yourself in a thread outside of the UI thread.
Usage
Simply import the gradle file into Android Studio and reference the dependancy in your settings.gradle
and project's build.gradle
Alternatively you can add the maven dependancy net.callumtaylor:asynchttpclient:2.1.1
N.B. Do NOT use net.callumtaylor.asynchttp
for the group ID. This is an old ID and will NOT be updated

Other notes
Downloading large files
In order to download large files, you will need to subclass AsyncHttpResponseHandler
and override the onByteChunkReceived()
method to write directly to cache instead of appending to a ByteArrayOutputStream
which is what the standard BinaryResponseHandler
does. This is to stop OOM due to a over-sized output stream.
AsyncHttpClient
Note: Because AsyncHttpClient
uses AsyncTask
, only one instance can be created at a time. If one client makes 2 requests, the first request is canceled for the new request. You can either wait for the first to finish before making the second, or you can create two seperate instances. See: Example custom handler for more.
SyncHttpClient
SyncHttpClient
is a paramitized class which means the type you infer to it, is the type that gets returned when calling the method. When supplying a ResponseHandler, that ResponseHandler must also paramitized with the same type as the SyncHttpClient
instance.
You can also get the info of the request by calling your SyncHttpClient
instance and getConnectionInfo()
. This can only be called after the response has been completed.
Note: Because Android requires all network requests to be performed outside the UI thread, you must use SyncHttpClient sparingly and make sure you handle the operaion OFF the UI thread.
Because of the nature of REST, GET
and DELETE
requests behave in the same way, POST
and PUT
requests also behave in the same way.
