模擬器上的Android c2dm服務器模擬器

Question

我正在通過以下鏈接關注android c2dm示例： http ://www.vogella.de/articles/AndroidCloudToDeviceMessaging/article.html

我已經成功實現了客戶端並獲得了我的注冊ID。 但是我在使用相同示例的服務器端遇到一些問題，實際上問題出在getAuthentification方法中，並且我在HttpResponse response = client.execute（post）處遇到以下異常。

java.net.UnknownHostException：www.google.com

以下是我的代碼：

    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(
            "https://www.google.com/accounts/ClientLogin");

    try {

        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
        nameValuePairs.add(new BasicNameValuePair("Email","you....@gmail.com"));
        nameValuePairs.add(new BasicNameValuePair("Passwd","*********"));
        nameValuePairs.add(new BasicNameValuePair("accountType", "GOOGLE"));
        nameValuePairs.add(new BasicNameValuePair("source",
                "Google-cURL-Example"));
        nameValuePairs.add(new BasicNameValuePair("service", "ac2dm"));

        post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = client.execute(post);
        BufferedReader rd = new BufferedReader(new InputStreamReader(
                response.getEntity().getContent()));

        String line = "";
        while ((line = rd.readLine()) != null) {
            Log.e("HttpResponse", line);
            if (line.startsWith("Auth=")) {
                Editor edit = prefManager.edit();
                edit.putString(AUTH, line.substring(5));
                edit.commit();
                String s = prefManager.getString(AUTH, "n/a");
                Toast.makeText(this, s, Toast.LENGTH_LONG).show();
            }

        }
    } catch (IOException e) {
        e.printStackTrace();
    }

請幫我？ 您的幫助將非常可觀。 謝謝，

上周我也遇到了同樣的問題。 當C2DM服務器返回302移動（www.google.com）時，它們的實際含義是認證失敗。 問題幾乎可以肯定是您的身份驗證代碼，因此請重新檢查用於從ClientLogin API獲取身份驗證代碼的代碼。 請注意，HTTP響應包含大量信息，而不僅僅是auth代碼，因此您需要正確解析它（這是我的錯誤）。

public static String getClientLoginAuthToken(String email, String password) {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("https://www.google.com/accounts/ClientLogin");
try {

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("Email", email));
nameValuePairs.add(new BasicNameValuePair("Passwd", password));
nameValuePairs.add(new BasicNameValuePair("accountType", "GOOGLE"));
nameValuePairs.add(new BasicNameValuePair("source","Google-cURL-Example"));
nameValuePairs.add(new BasicNameValuePair("service", "ac2dm"));

post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);
BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

String line = "";
while ((line = rd.readLine()) != null) {
    if (line.startsWith("Auth=")) {
        return line.substring(5);
    }
}
} catch (IOException e) {
    e.printStackTrace();
}
    Log.e(TAG, "Failed to get C2DM auth code");
    return "";
}
