Question

I have this strange problem. I am retrieving twitters and it works on the Emulator and also on my Samsung Galaxy S but it doesn’t work on my Galaxy Tab 10.1 ?

Same app installed on both the phone and the tab. Generated from Eclipse so no debugging or anything.

Different permissions needed?

This is the code:

HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(searchUrl);

ResponseHandler<String> responseHandler = new BasicResponseHandler();

responseBody = client.execute(get, responseHandler);

and this is the manifest:

<uses-sdk android:minSdkVersion="10" />

<uses-permission android:name="android.permission.INTERNET"  />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

I swear, this question is asked everyday here on StackOverflow. 🙂

The problem is that you are performing a network access on the main UI thread. Android 3.0 and above will crash your application (i.e. the system will throw a NetworkAccessOnMainThread exception) if you attempt to perform an HTTP request on the main thread. You need to wrap your HTTP request in an AsyncTask (or a Thread of some sorts) to ensure that you don’t block the UI thread.
