我正在构建一个Android应用程序，使用Google Get和HTTP Post与googles Service Auth进行通信，以验证我的Google凭据并返回结果。
这个程序在我的桌面PC上运行得很好但是当我将代码移动到android活动并尝试在那里使用它时，它每次都会失败。关于为什么会这样的任何想法？是否有理由说明HTTP Post或者在Android应用程序中获胜？
是的 - 我的清单中有以下权限：
<uses-permission android:name="android.permission.INTERNET" />
我的代码简述如下：
URL obj = new URL(url);
conn = (HttpsURLConnection) obj.openConnection();
// default is GET
conn.setRequestMethod("GET");
conn.setUseCaches(false);
// act like a browser
conn.setRequestProperty("User-Agent", USER_AGENT);
conn.setRequestProperty("Accept",
"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
conn.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
if (cookies != null) {
for (String cookie : this.cookies) {
conn.addRequestProperty("Cookie", cookie.split(";", 1)[0]);
}
}
int responseCode = conn.getResponseCode();
/* System.out.println("\nSending 'GET' request to URL : " + url);
System.out.println("Response Code : " + responseCode); */
BufferedReader in =
new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
// Get the response cookies
setCookies(conn.getHeaderFields().get("Set-Cookie"));
return response.toString();

此外，Logcat不断抛出以下错误：
