                }
            }
        });

    }

and the search method for GooglePlaces class is

public PlacesList search(double latitude, double longitude, double radius, String types)
        throws Exception {

    this._latitude = latitude;
    this._longitude = longitude;
    this._radius = radius;

    try {

        HttpRequestFactory httpRequestFactory = createRequestFactory(HTTP_TRANSPORT);
        HttpRequest request = httpRequestFactory
                .buildGetRequest(new GenericUrl(PLACES_SEARCH_URL));
        request.getUrl().put("key", API_KEY);
        request.getUrl().put("location", _latitude + "," + _longitude);
        request.getUrl().put("radius", _radius); // in meters
        request.getUrl().put("sensor", "false");
        if(types != null)
            request.getUrl().put("types", types);



        PlacesList list = request.execute().parseAs(PlacesList.class);
        // Check log cat for places response status
        Log.d("Places Status", "" + list.status);
        return list;

    } catch (HttpResponseException e) {
        Log.e("Error:", e.getMessage());
        return null;
    }

}

    You are leaking the dialog. You need to call pDialog.dismiss(); in the onPostExecute() method of the async task. You should also put…

    if(pDialog != null)
    pDialog.dismiss();

    in your onPause() method of the activity on the main thread. This will make sure the window is not leaked, even if your application loses the foreground while doing some background execution. You should have something like this…

    public class Login extends Activity implements View.OnClickListener{

    ProgressDialog pd;

    public void onCreate(Bundle savedInstanceState){

        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
        setContentView(R.layout.login);
        pd = null;
    } 

    @Override
    public void onPause(){

        super.onPause();
        if(pd != null)
            pd.dismiss();
    }

    public void onClick(View v){
        new SendTask().execute("");
    }

    /*
    No networking allowed on the main thread.
    */
    private class SendTask extends AsyncTask<String,String,String>{

        int result;

        @Override
        protected void onPreExecute(){
            pd = ProgressDialog.show(Login.this,"","Retrieving Inbox...", true,false);
        }

        @Override
        protected String doInBackground(String...strings){

            //do networking here
            result = account.prepare();
            return null;
        }

        @Override
        protected void onPostExecute(String unused){

            //check result
            pd.dismiss();
            Intent intent = new Intent(Login.this,NextActivity.class);
            finish();
            startActivity(intent);
        }
     }
}
