Question

我坚持将GCM推送通知集成到Android应用程序中。我获得了设备ID，服务器端似乎没问题，因为它给出了成功消息。我认为问题在于android部分。请检查我的代码。我的清单文件在下面提供。

下面提供了GCMBroadcastReceiver文件

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

    GcmBroadcastReceiver()
    {
        System.out.println("RECEIVER IS WORKING...");
    }

    @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());

        System.out.println("RECEIVED NOTIFICATION............");

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

    }
}

GCMMessageHandler类在下面给出

public class GcmMessageHandler extends IntentService implements Observer, AppConstants {

     String mes;
     private Handler handler;
    //private PushReceivingTemplate details;
    private BaseApp baseApp;

    public GcmMessageHandler() {
        super("GcmMessageHandler");

        System.out.println("HANDLER IS WORKING...");
    }

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

        baseApp = (BaseApp) getApplication();
        baseApp.getObserver().addObserver(this);

    }
    @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("message");
/*
        Gson gson = new Gson();
        Type collectionType = new TypeToken<PushReceivingTemplate>() {
        }.getType();
        details = gson.fromJson(mes, collectionType);

        final DatabaseHandler dbh = new DatabaseHandler(this);
        dbh.addNotidfications(details);

        //mes = getResources().getString(R.string.gcmPush);
        if(baseApp.getObserver().isAppIsInBackground(this))
        {
            NotificationUtils.displayNotification(this, details, baseApp);
        }
        //}*/

        System.out.println("____________________" + mes);
        GcmBroadcastReceiver.completeWakefulIntent(intent);
    }

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


    @Override
    public void update(Observable observable, Object data) {

    }
}

我从服务器收到此消息

{"multicast_id":6519739741263216481,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1457419626958900%8c03edcaf9fd7ecd"}]}

请解决问题。

Answer 1

您正在收到服务器消息，因此无法保留任何配置问题。

保留生成通知代码：

     @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("message");
    /*
            Gson gson = new Gson();
            Type collectionType = new TypeToken<PushReceivingTemplate>() {
            }.getType();
            details = gson.fromJson(mes, collectionType);

            final DatabaseHandler dbh = new DatabaseHandler(this);
            dbh.addNotidfications(details);

            //mes = getResources().getString(R.string.gcmPush);
            if(baseApp.getObserver().isAppIsInBackground(this))
            {
                NotificationUtils.displayNotification(this, details, baseApp);
            }
            //}*/

            System.out.println("____________________" + mes);

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.notification_icon)
            .setContentTitle("My notification")
            .setContentText(mes);
    // Creates an explicit intent for an Activity in your app
    Intent resultIntent = new Intent(this, ResultActivity.class);

    // The stack builder object will contain an artificial back stack for the
    // started Activity.
    // This ensures that navigating backward from the Activity leads out of
    // your application to the Home screen.
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    // Adds the back stack for the Intent (but not the Intent itself)
    stackBuilder.addParentStack(ResultActivity.class);
    // Adds the Intent that starts the Activity to the top of the stack
    stackBuilder.addNextIntent(resultIntent);
    PendingIntent resultPendingIntent =
            stackBuilder.getPendingIntent(
                0,
                PendingIntent.FLAG_UPDATE_CURRENT
            );
    mBuilder.setContentIntent(resultPendingIntent);
    NotificationManager mNotificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    // mId allows you to update the notification later on.
    mNotificationManager.notify(mId, mBuilder.build());


            GcmBroadcastReceiver.completeWakefulIntent(intent);
        }

希望这会对你有所帮助。

确保您的GcmMessageHandler放置在您在权限中定义的同一个包中，即com.purpletab.sanghi
