Question

服务器：

var GCM = require('gcm').GCM;

var apiKey = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXX';
var gcm = new GCM(apiKey);

var message = {
    registration_id: 'APA91bEAjoFkJu6KF-UgbLWhB-qbHs6fHeYANpB1XFT4Y8NQbjaOJPQ_PItvBpPF5Zi3thEB6H-_0SXkT7JcYB4yGMOa-jZyeygkxTzy56bbqG8zqLSGouFpSr4F5uGvHzEywH_E3Lko8W57XiCe8F_NJGSvkA0i1jAvXkVvCYTzEyar-OAec10', // required
    collapse_key: 'Collapse key', 
    'data.key1': 'value1',
    'data.key2': 'value2'
};

gcm.send(message, function(err, messageId){
    if (err) {
        console.log("Something has gone wrong!");
    } else {
        console.log("Sent with message ID: ", messageId);
    }
});

客户：

public class GcmMessageHandler extends IntentService {

     String mes;
     private Handler handler;
    public GcmMessageHandler() {
        super("GcmMessageHandler");
    }

    @Override
    public void onCreate() {
        // TODO Auto-generated method stub
        super.onCreate();
        handler = new Handler();
    }
    @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);

       mes = extras.getString("title");
       showToast();
       Log.i("GCM", "Received : (" +messageType+")  "+extras.getString("title"));

        GcmBroadcastReceiver.completeWakefulIntent(intent);

    }

    public void showToast(){
        handler.post(new Runnable() {
            public void run() {
                Toast.makeText(getApplicationContext(),mes , Toast.LENGTH_LONG).show();
            }
         });

    }
}

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        // Explicitly specify that GcmMessageHandler will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                GcmMessageHandler.class.getName());

        // Start the service, keeping the device awake while it is launching.
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }
}

它在昨天工作，但现在它没有在设备上显示任何内容。我不知道有什么不对。我没有改变任何事情。有人可以对此有所了解吗？（我正在使用真实的设备）

修改

它适用于模拟器。

检查此代码可能对您有帮助：

protected void gcm() {
    // TODO Auto-generated method stub
    GCMHelper gcmhelper = new GCMHelper();
    String gcmtokenAlready = gcmhelper.alreadyregisterGCM();
    if(gcmtokenAlready.length()>0){

        To do code here

    }else{
        gcmhelper.registerGCM();
    }

// GCMHelper

public class GCMHelper {
private final String SENDER_ID = ContextProvider.getContext().getResources().getString(R.string.GCM_ID);
private final Context context = ContextProvider.getContext();
/**
 *  This method is used to register the device with the GCM.
 *
 * @param context the context
 */
public void registerGCM() {
    GCMRegistrar.checkDevice(context);
    GCMRegistrar.checkManifest(context);        
    GCMRegistrar.register(context, SENDER_ID);
}

/**
 * Already register gcm.
 *
 * @param context the context

    GCMRegistrar.checkDevice(context);
