Question

Here is my code:

// begin the registration process
    status.setText("Registering...");
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("register.php");
    SharedPreferences settings = getSharedPreferences("settings", 0);
    String name = settings.getString("name", "");
    String email = settings.getString("email", "");
    String password = settings.getString("password", "");

    //get C2DM registration ID
    Context context = getApplicationContext();
    C2DMessaging.register(context, "qasim1iqbal");
    String reg_id = C2DMessaging.getRegistrationId(context);

    String HTML = "";
    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("name", name));
        nameValuePairs.add(new BasicNameValuePair("email", email));
        nameValuePairs.add(new BasicNameValuePair("password", password));
        nameValuePairs.add(new BasicNameValuePair("reg_id", reg_id));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        HttpResponse response = httpclient.execute(httppost);
        HTML = EntityUtils.toString(response.getEntity());
        Toast msg = Toast.makeText(getApplicationContext(), HTML, Toast.LENGTH_LONG);
        msg.show();

        Intent i = new Intent(getBaseContext(), doneRegisterActivity.class);
        startActivityForResult(i, 0);
    } catch (ClientProtocolException e) {
    } catch (IOException e) {
    }

I am getting a SERVICE_NOT_AVAILABLE error upon registration, what could be causing this? This is on an Activity.

From the C2DM page:

The device can’t read the response, or there was a 500/503 from the
server that can be retried later. The application should use
exponential back off and retry.

Probably a server hiccup. (IE, doubtful that it’s something on your end). Just to be sure, try using your credentials with one of the sample apps listed on that page, and see if it works there.
