Scribe-java and asynchronous request in Android 4

Question

In my Android 4.2.2 emulator, I am trying to use a scribe code snippet:

OAuthService service = new ServiceBuilder() .provider(TwitterApi.class) .apiKey("abc") .apiSecret("aaa123") .debug() .build(); Scanner in = new Scanner(System.in); Token requestToken = service.getRequestToken(); 

The following error appears in logcat. I think this may be due to the fact that Scribe this sample code is not an asynchronous task. Can you recommend an async example?

Please note that this piece of code works in Android 2.3.3. It does not work in Android 4.2.2.

Answer 1

This is because later versions of Android now require that network connections be disconnected from the main stream. I previously used AsyncTask for this, but it decomposes in a future version of Android.

I suggest using AsyncTaskLoader if you need to return the result and update the interface. Otherwise, you can use the IntentService (or any other Service type). You can also create a new thread . No matter what you decide, as soon as you move the connection from the main thread, you will no longer get a NetworkOnMainThreadException !

Answer 2

After @Jabari's answer, I will also add my answer.

Yes, the network connection must have a different thread than the user interface thread.
So I found that the loopj library is very good.
