You need to use an AsyncTask to do all your network operations.

Your network operation can take a lot of time and the UI would get unresponsive if it is done on the main UI thread. And if your UI freezes for a long time, the app might get killed by the OS.

Thus Android 4+ makes it mandatory to use a background thread to perform network operations.

Put the code to do the network activity inside doInBackground() and all the AsyncTask using execute().

Here is how your AsyncTask would look like :

private class MyAsyncTask extends AsyncTask<String, Integer, Void> {
     protected void doInBackground() {
        sendEmail();
 }

 protected void onProgressUpdate() {
    //called when the background task makes any progress
 }

  protected void onPreExecute() {
     //called before doInBackground() is started
 }
 protected void onPostExecute() {
     //called after doInBackground() has finished 
 }
  }

And you can call it anywhere using new MyAsyncTask().execute("");

You need to use an AsyncTask for newtwork operations , because running long operations on the main thread can make lags to your ui or even make it non responsive .

Although it is best to use AsyncTask , you can also just use an another thread

Like :

Thread xamp = new Thread(){

public void run(){
//Your network operation here
}

};
xamp.start();
