Error in app on Android 4.0 or higher

Question

The app starts without a problem but at the last step it closes with: Unfortunately, "YOURAPP" has stopped.

Log Cat gives me the following output, but I don't understand where the real problem is:

On Android 1.6, 2.1, 2.3.3 there is no problem. It only occurs with version 4.0 or higher

The log tells you what the problem is:

Caused by: android.os.NetworkOnMainThreadException

See the documentation for details and best practices.

This exception is thrown when an application attempts to perform a networking operation on its main thread. Run your code in AsyncTask: Document

class Task extends AsyncTask<Void, Void, Void> {

    private Exception exception;

    protected Void doInBackground(Void... v) {
        // do your tasks here
    }

    protected void onPostExecute(RSSFeed feed) {

    }
}

How to execute the task:

new Task().execute();

Don't forget to add Internet permissions to AndroidManifest.xml file:

You are trying to make network operations on the main thread.

http://developer.android.com/reference/android/os/NetworkOnMainThreadException.html

this has to be done inside its own thread.
