我开发了一个基本的聊天应用程序。我无法接收消息。谁可以帮我这个事？？我尝试在 Logcat 中检查此 GCMBroadcastReceiver 是否正常工作...... LogCat 中没有记录消息。

任何帮助都是可观的。

GCMBroadcastReceiver.java

package com.chaitukadivella.friendschat.client;

import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.ContentValues;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.PowerManager;
import android.os.PowerManager.WakeLock;
import android.support.v4.content.WakefulBroadcastReceiver;
import android.text.TextUtils;
import android.util.Log;

import com.chaitukadivella.friendschat.Common;
import com.chaitukadivella.friendschat.DataProvider;
import com.chaitukadivella.friendschat.MainActivity;
import com.chaitukadivella.friendschat.R;
import com.google.android.gms.gcm.GoogleCloudMessaging;


public class GcmBroadcastReceiver extends BroadcastReceiver {

private static final String TAG = "GcmBroadcastReceiver";

private Context ctx;    

@Override
public void onReceive(Context context, Intent intent) {
    ctx = context;
    Log.v(TAG,"Entered Broadcast Receiver");
    PowerManager mPowerManager = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
    WakeLock mWakeLock = mPowerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, TAG);
    mWakeLock.acquire();

    try {
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context);

        String messageType = gcm.getMessageType(intent);
        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
            sendNotification("Send error", false);

        } else if     (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
            sendNotification("Deleted messages on server", false);

        } else {
            String msg = intent.getStringExtra(DataProvider.COL_MSG);
            String email =     intent.getStringExtra(DataProvider.COL_FROM);

            ContentValues values = new ContentValues(2);
            values.put(DataProvider.COL_MSG, msg);
            values.put(DataProvider.COL_FROM, email);
                context.getContentResolver().insert(DataProvider.CONTENT_URI_MESSAGES, values);

            if (Common.isNotify()) {
                sendNotification("New message", true);
            }
        }
        setResultCode(Activity.RESULT_OK);

    } finally {
        mWakeLock.release();
    }
}

private void sendNotification(String text, boolean launchApp) {
    Log.v(TAG,"Entered Send Notification");
    NotificationManager mNotificationManager = (NotificationManager)     ctx.getSystemService(Context.NOTIFICATION_SERVICE);

    Notification.Builder mBuilder = new Notification.Builder(ctx)
        .setAutoCancel(true)
        .setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle(ctx.getString(R.string.app_name))
        .setContentText(text);

    if (!TextUtils.isEmpty(Common.getRingtone())) {
        mBuilder.setSound(Uri.parse(Common.getRingtone()));
    }

    if (launchApp) {
        Intent intent = new Intent(ctx, MainActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |     Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent pi = PendingIntent.getActivity(ctx, 0, intent,     PendingIntent.FLAG_UPDATE_CURRENT);
        mBuilder.setContentIntent(pi);
    }

    //mNotificationManager.notify(1, mBuilder.getNotification());
    mNotificationManager.notify(1, mBuilder.build());
}
}
