That was not an error, it was a warning. And if when you add a Looper.prepare() the app crashes, then how is that connected to AHC? AHC works in both situations, with or without a handler, so your app needs to support either of these.

The difference between 1.4.4 and 1.4.5 is simple: in prior versions, AHC automatically created the looper when it didn't exist, which was alright in situations but not alright in other situations. So we removed it and now the developer needs to prepare a looper beforehand.

@neoteknic if you add Looper.prepare() what StackTrace do you see in console? Post it please.
Also, in your particular use-case, should the request be synchronous or asynchronous? Thanks

it's very weird to call a async http lib API in an async thread....

@lbt05 yes, that is not the way the library is meant to be used, however it fits someones needs, so we'd like to support them.

Hello,
For Looper.prepare() if I call it it just crash the app.
It use to work in the previous version but as lbtp5 says I am already in a thread and in this case I dont need another thread. So I just changed a bit my code to use SyncHttp. The problem is that the new version dont allow this possibility in my Webservoce class I have also a method private void notify() called in onSuccess or after http post if if fail to catch the error. This method send a callback to an Activity or fragment class wich implement a notify listener.
No I dont need a thread in a thread, but why it was possible in the previous version, with the async with no looper prepare warning it swich to a sync http client but later you have a NPE because you use AHC instead of SyncHttpClient. Just produce a fatal error in the Looper.prepare test, not a warning maybe.

@neoteknic can you post the stacktraces?

I will try to revert to my previous code to do that.

If you still suffer from the issue, send back the stacktraces.
In other way, you should use AsyncHttpClient aClient = new SyncHttpClient(); constructor

See this example of running requests in background thread:
https://github.com/loopj/android-async-http/blob/master/sample/src/main/java/com/loopj/android/http/sample/services/ExampleIntentService.java

I want an Async request. Do I neet to use IntentService? Can't I make it to something closer to previous versions of loopj?
