當我向設備發送通知時，此設備會收到推送消息，但會收到「com.google.android.c2dm.intent.REGISTRATION」意圖，而不是「com.google.android .c2dm.intent.RECEIVE」。 如果我嘗試發送第二個通知，我會收到Google發出的「NotRegistered」錯誤。Android c2dm自動取消註冊
該設備獲得註冊罰款（我猜），因爲我得到的身份驗證令牌「APA91 ... -119個字符」。
這裏是我的代碼，開始註冊設備：
Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
registrationIntent.putExtra("sender", "EMAIL");
startService(registrationIntent);
發件人（這是在Android設備上完成）：
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", "SAME AS LOGIN"));
nameValuePairs.add(new BasicNameValuePair("Passwd", "****"));
nameValuePairs.add(new BasicNameValuePair("accountType", "HOSTED_OR_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("C2DM", line);
if (line.startsWith("Auth=")) {
s = line.substring(5);//LOGIN TOKEN
Log.i("C2DM", "Token get: "+ s);
String auth_key = s; /* GETTING THE AUTH TOKEN FROM SERVER */
StringBuilder postDataBuilder = new StringBuilder();
postDataBuilder.append(PARAM_REGISTRATION_ID).append("=").append(auth_key);
postDataBuilder.append("&").append(PARAM_COLLAPSE_KEY).append("=").append("0");
postDataBuilder.append("&").append("data.info").append("=").append(URLEncoder.encode("Invitar", UTF8));
URLEncoder.encode(telephonyManager.getDeviceId(), UTF8));
byte[] postData = postDataBuilder.toString().getBytes(UTF8);
URL url = new URL("https://android.clients.google.com/c2dm/send");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded;charset=UTF-8");
conn.setRequestProperty("Content-Length",Integer.toString(postData.length));
conn.setRequestProperty("Authorization", "GoogleLogin auth="+ auth_key);
OutputStream out = conn.getOutputStream();
out.write(postData);
out.close();
int responseCode = conn.getResponseCode();
Log.e("C2DM", String.valueOf(responseCode));
// Validate the response code
if (responseCode == 401 || responseCode == 403) {
Log.e("C2DM", "Unauthorized - need token");
}
// Check for updated token header
String updatedAuthToken = conn.getHeaderField(UPDATE_CLIENT_AUTH);
if (updatedAuthToken != null && !auth_key.equals(updatedAuthToken)) {
Log.i("C2DM","Got updated auth token from datamessaging servers: "+ updatedAuthToken);
Editor edit = prefManager.edit();
edit.putString(AUTH, updatedAuthToken);
}
String responseLine = new BufferedReader(new InputStreamReader(conn.getInputStream())).readLine();
if (responseLine == null || responseLine.equals("")) {
Log.i("C2DM", "Got " + responseCode+ " response from Google AC2DM endpoint.");
throw new IOException("Got empty response from Google AC2DM endpoint.");
}
String[] responseParts = responseLine.split("=", 2);
if (responseParts.length != 2) {
Log.e("C2DM", "Invalid message from google: " + responseCode+ " " + responseLine);
throw new IOException("Invalid response from Google "+ responseCode + " " + responseLine);
}
if (responseParts[0].equals("id")) {
Log.i("C2DM", "Successfully sent data message to device: "+ responseLine);
retval = 1;
}
if (responseParts[0].equals("Error")) {
String err = responseParts[1];
Log.w("C2DM","Got error response from Google datamessaging endpoint: "+ err);
// No retry.
throw new IOException(err);
}
return sendMessage();
}
}
} catch (IOException e) {
e.printStackTrace();
}
我reciever：
public void onReceive(Context context, Intent intent) {
Log.d("C2DM", "Intent recieved: "+intent.getAction());
if (intent.getAction().equals("com.google.android.c2dm.intent.REGISTRATION")) {
handleRegistration(context, intent);
} else if (intent.getAction().equals("com.google.android.c2dm.intent.RECEIVE")) {
handleMessage(context, intent);
}
}
private void handleRegistration(Context context, Intent intent) {
String registration = intent.getStringExtra("registration_id");
if (intent.getStringExtra("error") != null) {
// Registration failed, should try again later.
Log.d("C2DM", "registration failed");
String error = intent.getStringExtra("error");
if(error == "SERVICE_NOT_AVAILABLE"){
Log.d("c2dm", "SERVICE_NOT_AVAILABLE");
}else if(error == "ACCOUNT_MISSING"){
Log.d("c2dm", "ACCOUNT_MISSING");
}else if(error == "AUTHENTICATION_FAILED"){
Log.d("c2dm", "AUTHENTICATION_FAILED");
}else if(error == "TOO_MANY_REGISTRATIONS"){
Log.d("c2dm", "TOO_MANY_REGISTRATIONS");
}else if(error == "INVALID_SENDER"){
Log.d("c2dm", "INVALID_SENDER");
}else if(error == "PHONE_REGISTRATION_ERROR"){
Log.d("c2dm", "PHONE_REGISTRATION_ERROR");
}
} else if (intent.getStringExtra("unregistered") != null) {
//HERE IS WHERE ARRIVES THE SEND NOTIFICATION (NOT THE UNREGISTER NOTIFICATION)
Log.d("C2DM", "unregistered: "+intent.getStringExtra("unregistered"));
} else if (registration != null) {
Log.d("C2DM", registration);
/* SENDING THE AUTH TOKET TO SERVER */
}
}
我在設備上執行推送通知，因爲如果我在服務器端執行操作，我總是會收到「InvalidRegistration」錯誤。
奇怪的是，它似乎我已經註冊，但當我發送一個推送消息，就像谷歌取消註冊設備。
任何想法/建議？
我改進了代碼，現在，我在我的服務器（php）中執行了ac2dm服務，但響應是相同的，在設備上我收到請求註銷的設備。代碼是這樣的：[鏈接]（http://stackoverflow.com/questions/4121508/c2dm-implementation-php-code） – Guillem 2011-05-24 08:31:30
我也面臨同樣的問題..請幫我 – Jomia 2011-09-12 05:40:42
