My app is not working on android version 4.1 gives exception like android.os.NetworkOnMainThreadException
i have search on stackoverflow advice me to do network thread in background AsyncTask so before use backgroundtask,
My screen look like this https://i.sstatic.net/PZxPR.jpg show multiple rows in nutrition's and ingredient tags after using backgroundtask my screen look like this https://i.sstatic.net/91qhg.jpg show only single row in ingredients and nutrition tags
before background task code is this see below
public class fifthscreen extends Activity {

Please Help
Thanks in Advance...:)
You can use **runOnUiThread()** like this:
try {
// code runs in a thread
runOnUiThread(new Runnable() {
@Override
public void run() {
// YOUR CODE
}
});
} catch (final Exception ex) {
Log.i("---","Exception in thread");
}
