Question

我正在根据此处提供的示例创建GCM客户端 - http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/和此处 - http://developer.android.com/google/gcm/client.html。基本上，它只是做了第一个例子，但我更新它以使用GoogleCloudMessaing API。

作为服务器，我使用了第一个链接中使用的示例php服务器。但是当我通过php脚本发送消息时，我的设备上没有收到任何消息。

在服务器端，我使用mysql密码和Google API密钥修改了config.php文件。

    ?php
    /**
      * Database config variables
    /
   define("DB_HOST", "localhost");
   define("DB_USER", "root");
   define("DB_PASSWORD", "password");
   define("DB_DATABASE", "gcm");

  /*
   * Google API Key
   */
   define("GOOGLE_API_KEY", "MY GOOGLE API KEY"); // Place your Google API Key

我在gcm_users表中手动创建了一个条目，这样我就不必从我的应用程序发送注册ID了。该表包含第一个链接中提到的regId，name，email。

然后我从index.php页面发送一条消息，但是从未收到该消息。

        </intent-filter>
    </receiver>
    <service android:name=".GCMIntentService" />
</application>

GCMIntentService.java文件：

    package com.example.gcmclient;

    import android.app.IntentService;
    import android.content.Intent;
    import android.os.Bundle;

    import com.google.android.gms.gcm.GoogleCloudMessaging;

    public class GCMIntentService extends IntentService {
public GCMIntentService() {
    super("GCMIntentService");
}

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);

    String messageType = gcm.getMessageType(intent);

    if (!extras.isEmpty()) {  // has effect of unparcelling Bundle
            /*
             * Filter messages based on message type. Since it is likely that GCM will be
             * extended in the future with new message types, just ignore any message types you're
             * not interested in, or that you don't recognize.
             */
        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
            Utilities.showNotification(this, "Send error: " + extras.toString());
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
            Utilities.showNotification(this, "Deleted messages on server: " + extras.toString());
            // If it's a regular GCM message, do some work.
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
            Utilities.showNotification(this, "Received: " + extras.toString());
        }
        // Release the wake lock provided by the WakefulBroadcastReceiver.
        GCMBroadcastReceiver.completeWakefulIntent(intent);
    }
}

}

我已经确认我已正确注册gcm服务器并且服务器将注册ID返回到我的应用。 RegisterActivity.java文件的主要部分：

    private void registerInBackground() {
    new AsyncTask<Void, Void, String>() {
        private Random mRandom = new Random();
        private long mBackoff = BACKOFF_MILLI_SECONDS + mRandom.nextInt(1000);

        private ProgressDialog mDialog;

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            mDialog = new ProgressDialog(mContext);
            mDialog.setMessage("Registering with Google Cloud Messaging (GCM)");
            mDialog.setIndeterminate(true);
            mDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
            mDialog.setCancelable(false);
            mDialog.show();
        }

        @Override
        protected String doInBackground(Void... params) {
            String msg = "";
            for (int i = 1; i <= MAX_ATTEMPTS; i++, mBackoff *= 2) {
                msg = "";
                try {
                    if (mGcm == null) {
                        mGcm = GoogleCloudMessaging.getInstance(mContext);
                    }
                    mRegId = mGcm.register(SENDER_ID);
                    msg = "Device registered, registration ID = " + mRegId;
                    storeRegistrationId(mContext, mRegId);
                    break;
                } catch (IOException e) {
                    Log.d(TAG, e.toString());
                    // If there is an error, don't just keep trying to register.
                    // Require the user to click a button again, or perform
                    // exponential back-off.
                    Log.d(TAG, "Failed to register on attempt: " + i);
                    try {
                        Log.d(TAG, "Sleeping for " + mBackoff + " ms before retry");                        
                        Thread.sleep(mBackoff);
                    } catch(InterruptedException e1) {
                         Log.d(TAG, "Thread interrupted: abort remaining retries!");
                         Thread.currentThread().interrupt();
                         return msg;
                    }
                }
            }
            return msg;
        }

注册后，我的应用程序收到一条带有注册ID的广播消息。

09-16 19：27：41.970：D / GCMBoradcastReceiver（19723）：onReceive调用：Key = registration_id value =

我在我的mysql数据库表中复制了。

我在本地PC上运行服务器，其IP地址为192.168.1.139（没有公共IP）。 IPtables的输出 -

    Chain INPUT (policy ACCEPT)
    target     prot opt source               destination         

    Chain FORWARD (policy ACCEPT)
    target     prot opt source               destination         

    Chain OUTPUT (policy ACCEPT)
    target     prot opt source               destination         
    ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:5228
    ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:5229
    ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:5230

Apache日志显示来自index.php的原始发送请求的状态ok（200）。

那我错过了什么？任何帮助将不胜感激。

你GCMIntentService不像GCM说的那样......

public class GCMIntentService extends GCMBaseIntentService {

    @SuppressWarnings("hiding")
    private static final String TAG = "GCMIntentService";

    public GCMIntentService() {
        super(Utility.SENDER_ID);
    }

    @Override
    protected void onRegistered(Context context, String registrationId) {
        Log.i(TAG, "Device registered: regId = " + registrationId);

    }

    @Override
    protected void onUnregistered(Context context, String registrationId) {
        Log.i(TAG, "Device unregistered");

    }

    @Override
    protected void onMessage(Context context, Intent intent) {
        Log.i(TAG, "Received message");

    }

    @Override
    protected void onDeletedMessages(Context context, int total) {
        Log.i(TAG, "Received deleted messages notification");

    }

    @Override
    public void onError(Context context, String errorId) {
        Log.i(TAG, "Received error: " + errorId);

    }

    @Override
    protected boolean onRecoverableError(Context context, String errorId) {
        // log message
        Log.i(TAG, "Received recoverable error: " + errorId);

        return super.onRecoverableError(context, errorId);
    }
}

未收到来自GCM服务器的消息
