当我向设备发送通知时，该设备收到推送消息，但它收到“com.google.android.c2dm.intent.REGISTRATION” Intent ，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“NotRegistered”错误。

设备注册正常(我猜)，因为我获得了身份验证 token “APA91...-119 个字符-”。

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(这是在 Android 设备中完成的):

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"));

            OutputStream out = conn.getOutputStream();
            out.write(postData);
            out.close();

            int responseCode = conn.getResponseCode();

            Log.e("C2DM", String.valueOf(responseCode));
            // Validate the response code

                Log.i("C2DM","Got updated auth token from datamessaging servers: "+ updatedAuthToken);
                Editor edit = prefManager.edit();

                throw new IOException("Got empty response from Google AC2DM endpoint.");

            String[] responseParts = responseLine.split("=", 2);

                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 */
    }
}

我在设备上推送通知，因为如果我在服务器端推送通知，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？

最佳答案

我遇到了同样的问题并解决了它。

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 Intent 而不是许可

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

然后它就正常工作了 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>
