title: Backgroundservice and sending Requests
body: <p>I created a Backgroundservice where i want to send SMS in the Background when i press the power button for example.</p>
  
  <p>This is my code for sending sms when i press the power button:</p>
  
  <pre><code>public boolean onKeyDown(int keyCode, KeyEvent event) {
          if (event.getKeyCode() == KeyEvent.KEYCODE_POWER) {
              SmsManager smsManager = SmsManager.getDefault();
   smsManager.sendTextMessage(phoneNo, null, "Ich brauche Hilfe! Hier ist mein aktueller Standort, kannst du mir helfen kommen?" + "\n" + "http://maps.google.com/?q=" + lat + "," + lon, null, null);
      return true;
         }
      return super.onKeyDown(keyCode, event);
  </code></pre>
  
  <p>What i want to ask is: Do i need to write this code into my Backgroundervice and start the Service in the MainActivty onKeyDown? or keep it in my MainActivity?</p>
