gcm没有在客户端收到消息

Question

我的服务器正在向 gcm serer 发送消息，响应代码为 200。但我的 OnMessageReceiver 没有被调用，因此我没有收到消息。

公共类 MyGcmListenerService 扩展 GcmListenerService {

private static final String TAG = "MyGcmListenerService";
private static int no_calls;


    @Override
    public void onMessageReceived (String from, Bundle data){
        String message = data.getString("message");
        Log.d(TAG, "From: " + from);
        Log.d(TAG, "Message: " + message);

        out.println("print something");

        System.out.println("Message" + message + "from" + from);

        sendNotification(message);
    }



private void sendNotification(String message) {

    System.out.println("Message" + message + "from");

    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_setting_dark)
            .setContentTitle("GCM Message")
            .setContentText(message)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

将清单中的reciever 替换为receiver。 此外，请确保您的应用成功获得令牌（注册设备 ID）。希望这会有所帮助！

我的清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.gcmclient" >

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

<permission android:name="com.example.gcm.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />
<uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" />


<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <receiver
        android:name="com.google.android.gms.gcm.GcmReceiver"
        android:exported="true"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.example.gcm" />
        </intent-filter>
    </receiver>
    <service android:name=".service.GcmService" android:exported="false">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        </intent-filter>
    </service>

    <service android:name=".service.LoggingService" android:exported="false" />

    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:clearTaskOnLaunch="false"
        android:finishOnTaskLaunch="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

此外，请在发送后检查您的服务器端响应。如果 GCM 消息发送成功，您可能会收到如下响应消息：

{"multicast_id":6371085842931382567,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1240780242421810%4c427ca6f9fd7ecd"}]}

关于获取token，首先查看SharedPreferences，如果为空，则从Google服务器获取token（设备注册id）。令牌将存储在 SharedPreferences 中以供其他用途/提供给服务器端应用程序。

public class MainActivity extends Activity {

Context mContext = this;   

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ...
    SharedPreferences appPrefs = mContext.getSharedPreferences("com.example.gcmclient_preferences", Context.MODE_PRIVATE);
    String token = appPrefs.getString("token", "");
    if (token.isEmpty()) {
        try {
            getGCMToken("0123456789"); // Project ID: xxxx Project Number: 0123456789 at https://console.developers.google.com/project/...
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
    ...
}
...

private void getGCMToken(final String senderId) throws Exception {
    new AsyncTask<Void, Void, Void>() {
        @Override
        protected String doInBackground(Void... params) {
            String token = "";
            try {
                InstanceID instanceID = InstanceID.getInstance(mContext);
                token = instanceID.getToken(senderId, GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
                if (token != null && !token.isEmpty()) {
                    SharedPreferences appPrefs = mContext.getSharedPreferences("com.example.gcmclient_preferences", Context.MODE_PRIVATE);
                    SharedPreferences.Editor prefsEditor = appPrefs.edit();
                    prefsEditor.putString("token", token);
                    prefsEditor.commit();
                }
                Log.i("GCM_Token", token);
            } catch (IOException e) {
                e.printStackTrace();
            }    
            return null;            
        }           
    }.execute();
}   
}

Answer 2

改变这一行

android:name=".MyGcmListenerService"

而不是上面一行

android:name="你的包.MyGcmListenerService"

示例 com.yourappname.gcm.GcmIntentService

<service
        android:name=".MyGcmListenerService"
        android:exported="false" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        </intent-filter>
    </service>

BroadCastReceiver 的简单示例代码。

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    // Explicitly specify that GcmIntentService will handle the intent.
    ComponentName comp = new ComponentName(context.getPackageName(),
            GcmIntentService.class.getName());
    // Start the service, keeping the device awake while it is launching.
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);
}
}

意图服务

public class GcmIntentService extends IntentService {
 @Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    // The getMessageType() intent parameter must be the intent you received
    // in your BroadcastReceiver.
    String messageType = gcm.getMessageType(intent);

    if (!extras.isEmpty()) {  // has effect of unparcelling Bundles
        /*
         * 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)) {
            sendNotification("Send error: " + extras.toString());
        } else if (GoogleCloudMessaging.
                MESSAGE_TYPE_DELETED.equals(messageType)) {
            sendNotification("Deleted messages on server: " +
                    extras.toString());
            // If it's a regular GCM message, do some work.
        } else if (GoogleCloudMessaging.
                MESSAGE_TYPE_MESSAGE.equals(messageType)) {
          Log.e(":::gcm message",extras.getString("key");

        }
    }
    // Release the wake lock provided by the WakefulBroadcastReceiver.
    GcmBroadcastReceiver.completeWakefulIntent(intent);
}
}

从清单中删除以下行
