Android c2dm 自动注销

【中文标题】Android c2dm 自动注销

【英文标题】：Android c2dm automatically unregistered

【问题描述】：

当我向设备发送通知时，该设备会收到推送消息，但它会收到“com.google.android.c2dm.intent.REGISTRATION”意图，而不是“com.google.android.c2dm.intent” 。收到”。 如果我尝试发送第二个通知，我会收到来自 Google 的“未注册”错误。

设备注册良好（我猜），因为我得到了 Auth 令牌“APA91...-119 characters-”。

这是我开始注册设备的代码：

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);

发件人（在 Android 设备中完成）：

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);

        String line = "";
        while ((line = rd.readLine()) != null)

                Log.i("C2DM", "Token get: "+ s);
                    String auth_key = s; /* GETTING THE AUTH TOKEN FROM SERVER */

                    postDataBuilder.append(PARAM_REGISTRATION_ID).append("=").append(auth_key);
                    postDataBuilder.append("&").append(PARAM_COLLAPSE_KEY).append("=").append("0");

            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);

                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();
    

我的收件人：

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 */
    

我在设备上执行推送通知，因为如果我在服务器端执行，我总是会收到“InvalidRegistration”错误。

奇怪的是，我好像注册了，但是当我发送一条推送消息时，就像谷歌取消注册设备一样。

有什么想法/建议吗？

【问题讨论】：

我改进了代码，现在，我在我的服务器 (php) 中执行 ac2dm 服务，但响应是相同的，在我收到取消注册请求的设备上。代码和这里一样：link

我也面临同样的问题..请帮助我

【参考方案1】：

我遇到了同样的问题并解决了。

这是错误的代码

<receiver android:name=".MyC2DMReceiver"
            android:permission="com.google.android.c2dm.permission.SEND">
      <intent-filter>
          <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
          <category android:name="com.package.myapp" />
      </intent-filter>
      <intent-filter>
          <action android:name="com.google.android.c2dm.permission.RECEIVE" />
          <category android:name="com.package.myapp" />
      </intent-filter>
  </receiver>

我有写作意图而不是许可

com.google.android.c2dm.permission.RECEIVE => com.google.android.c2dm.intent.RECEIVE

然后它工作正常 所以RECEIVE的包名是错误的

正确的代码

<receiver android:name=".MyC2DMReceiver"
            android:permission="com.google.android.c2dm.permission.SEND">
      <intent-filter>
          <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
          <category android:name="com.package.myapp" />
      </intent-filter>
      <intent-filter>
          <action android:name="com.google.android.c2dm.intent.RECEIVE" />
          <category android:name="com.package.myapp" />
      </intent-filter>
  </receiver>

【参考方案2】：

有时，解决方案就在你面前而你看不到，对于那些和我有同样问题的人来说，问题在 Manifest 中，我没有写好包名

您能提供更多信息吗？我遇到了同样的问题。我的清单中没有发现任何问题。
