I am having a strange problem with Loopj Async HTTP library. I sometimes get the response using GET or POST, sometimes the response comes after a long time, some times the response does not come at all. This happens only when wifi is used. I have used loopj in so many projects and those work fine with wifi but not this project. When I use my mobile data 3G connection, always the response comes. I have overridden the onFaliure method and this is what I get when the response from server does not come:

E/statusCode(31980): 0
E/headers(31980): null
E/Throwable(31980): org.apache.http.conn.ConnectTimeoutException: Connect to .. timed out
E/errorResponse(31980): null

An Exception also gets printed on logcat:

I would greatly appreciate if some solution can be shown.

Try this:

AsyncHttpClient client = new AsyncHttpClient();
client.setTimeout(60000);

That will set the request timeout and then you will have the time you need.

This bug was introduced on 1.4.4;

Try use this library instead: https://github.com/leonardoxh/AsyncOkHttpClient

This library uses OkHttp (from Square Inc.) instead of Apache Http Client, and also is the codes for 2.0 Loopj Library

More than an year later this error keeps popping up from time to time. Quite interestingly even though the stacktrace says

"response body is null, calling onFailure(Throwable, JSONObject)"

The actual method that's invoked is onFailure(statusCode, headers, throwable, (JSONObject) null);

This is as per line 231 JsonHttpResponseHandler.java this would suggest that the method with the following signature is the one to be overridden:

public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject errorResponse)
