Хорошо, я нашел лучшее решение, я написал это, используя HttpGet
/***************************************************************************************************************************/
/* RETURNS Calendar List */
/***************************************************************************************************************************/
//@param authKey, represents the token key ,Auth=......
public void calendarList(String authKey){
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet("https://www.google.com/calendar/feeds/default/allcalendars/full");
httpget.setHeader("Authorization","GoogleLogin "+authKey);
// Execute HTTP Post Request
org.apache.http.HttpResponse response;
try {
response = httpclient.execute(httpget);
HttpEntity httpEntity = response.getEntity();
InputStream stream = httpEntity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(stream));
StringBuilder total = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
total.append(line);
Log.d("RESPONSE LIST",line+"\n");
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
