android.view.ViewRoot$CalledFromWrongThreadException:
I'm getting an error in my logcat stating:
java.net.UnknownHostException: apps.example.com
09-13 14:57:28.970: W/System.err(3823): android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.
Has anyone seen this before? I'm not sure exactly what's causing the issue.

In
protected InputStream doInBackground(String... params)
You have
stream = getQueryResults(Base_URL);
Then In getQueryResults you have
catch (Exception e) {
Log.e(LOG_TAG, e.toString());
tryagain();
}
The In tryagain you have
public void tryagain() {
setContentView(R.layout.tryagain);
You cannot update/access ui from a background thread. That is why you are getting that exception.
Also you should re consider your design. If you have setContentView more than once in the same activity re consider your design.
Also instead of mutiple try blocks have one try block and multiple catch blocks.
Not sure what you want but you are calling publishProgress more than once.

android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.
Looks like you are trying to update the UI on a background Thread like in doInBackground() of your AsyncTask. You can't do this. You need to update the UI on a UI Thread. Use any of the other AsyncTask methods to do this such as
onPreExecute()
onProgressUpdate()
or
onPostExecute()
you may also want to see

You are trying to update an UI element from a Thread that is not the UI Thread.
