GCMRegistrar.register give 不起作用.相同的代码在其他应用程序中工作

Question

我已经为GCM创建了一个演示应用程序，它的工作非常完美。但是当我在我的应用程序中集成相同的代码时 gcm.register 不起作用

这是我的 GCM 服务源代码

public class GCMIntentService extends GCMBaseIntentService {
    private static final String TAG = "GCMIntentService";
    public GCMIntentService() {
        super(CommonUtilities.SENDER_ID);
    }
    /**
     * Method called on device registered
     **/
    @Override
    protected void onRegistered(Context context, String registrationId) {
        Log.i(TAG, "Device registered: regId = " + registrationId);
        CommonUtilities.displayMessage(context, "Your device registred with GCM");
       // Log.d("NAME", MainActivity.name);
        ServerUtilities.register(context,"","", registrationId);
    }
    /**
     * Method called on device un registred
     * */
    @Override
    protected void onUnregistered(Context context, String registrationId) {
        Log.i(TAG, "Device unregistered");
        CommonUtilities.displayMessage(context, getString(R.string.gcm_unregistered));
        ServerUtilities.unregister(context, registrationId);
    }
    /**
     * Method called on Receiving a new message
     * */
    @Override
    protected void onMessage(Context context, Intent intent) {
        Log.i(TAG, "Received message");
        String message = intent.getExtras().getString("message");
        CommonUtilities.displayMessage(context, message);
        // notifies user
        generateNotification(context, message);
    }
    /**
     * Method called on receiving a deleted message
     * */
    @Override
    protected void onDeletedMessages(Context context, int total) {
        Log.i(TAG, "Received deleted messages notification");
        String message = getString(R.string.gcm_deleted, total);
        CommonUtilities.displayMessage(context, message);
        // notifies user
        generateNotification(context, message);
    }
    /**
     * Method called on Error
     * */
    @Override
    public void onError(Context context, String errorId) {
        Log.i(TAG, "Received error: " + errorId);
        CommonUtilities.displayMessage(context, getString(R.string.gcm_error, errorId));
    }
    @Override
    protected boolean onRecoverableError(Context context, String errorId) {
        // log message
        Log.i(TAG, "Received recoverable error: " + errorId);
        CommonUtilities.displayMessage(context, getString(R.string.gcm_recoverable_error,
                errorId));
        return super.onRecoverableError(context, errorId);
    }
    /**
     * Issues a notification to inform the user that server has sent a message.
     */
    private static void generateNotification(Context context, String message) 
    {
        int icon = R.drawable.ic_launcher;
        long when = System.currentTimeMillis();
        NotificationManager notificationManager = (NotificationManager)
                context.getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(icon, message, when);
        String title = context.getString(R.string.app_name);
        Intent notificationIntent = new Intent(context, HomeActivity.class);
        // set intent so it does not start a new activity
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
                Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent intent =
                PendingIntent.getActivity(context, 0, notificationIntent, 0);
        notification.setLatestEventInfo(context, title, message, intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        // Play default notification sound
        notification.defaults |= Notification.DEFAULT_SOUND;
        //notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "your_sound_file_name.mp3");
        // Vibrate if vibrate is enabled
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notificationManager.notify(0, notification);      
    }
}

GCM 寄存器的源代码

private void CheckDeviceRegistrationWithGCM()
{
    cd = new ConnectionDetector(getApplicationContext());
    // Check if Internet present
    if (!cd.isConnectingToInternet()) {
        // Internet Connection is not present
        alert.showAlertDialog(LoginActivity.this,
                "Internet Connection Error",
                "Please connect to working Internet connection", false);
        // stop executing code by return
        return;
    }

    // Make sure the device has the proper dependencies.
            GCMRegistrar.checkDevice(this);
            // Make sure the manifest was properly set - comment out this line
            // while developing the app, then uncomment it when it's ready.
            GCMRegistrar.checkManifest(this);

            registerReceiver(mHandleMessageReceiver, new IntentFilter(
                    DISPLAY_MESSAGE_ACTION));
            // Get GCM registration id
            final String regId = GCMRegistrar.getRegistrationId(this);
            // Check if regid already presents
            if (regId.equals("")) {
                // Registration is not present, register now with GCM           
                GCMRegistrar.register(this, CommonUtilities.SENDER_ID);
            } else {
                // Device is already registered on GCM
                if (GCMRegistrar.isRegisteredOnServer(this)) {
                    // Skips registration.              
                    Toast.makeText(getApplicationContext(), "Already registered with GCM", Toast.LENGTH_LONG).show();
                } else 
                {
                    // Try to register again, but not in the UI thread.
                    // It's also necessary to cancel the thread onDestroy(),
                    // hence the use of AsyncTask instead of a raw thread.
                      final Context context = this;
                      mRegisterTask = new AsyncTask<Void, Void, Void>() {

                            ServerUtilities.register(context,"","", regId);
                            Log.d(getClass().getName(),"Registration Id"+regId);
                            return null;
                        }
                        @Override
                        protected void onPostExecute(Void result) {
                            mRegisterTask = null;
                        }
                    };
                    mRegisterTask.execute(null, null, null);
                    if(!regId.equals(""))
                    {
                        ServerUtilities.register(getApplicationContext(),"","", regId);
                    }
                }
            }

我尝试了很多，但找不到解决方案，请给出提示，以便我可以提前进一步感谢

Answer 1

首先，GCMRegistrar 已被弃用。您应该改用GoogleCloudMessaging.register方法。

也就是说，您的清单有一些不一致之处：

    <permission
     android:name="com.example.permission.C2D_MESSAGE"
     android:protectionLevel="signature" />
<uses-permission android:name="com.example.permission.C2D_MESSAGE" />
<receiver
    android:name="com.google.android.gcm.GCMBroadcastReceiver"
    android:permission="com.google.android.c2dm.permission.SEND" >
    <intent-filter>
        <!-- Receives the actual messages. -->
        <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        <!-- Receives the registration id. -->
        <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
        <category android:name="com.example.notification" />
    </intent-filter>
</receiver>

在前两个位置（权限定义和用法），使用 com.example 作为应用的包。在第三个位置（广播接收器的类别），您使用com.example.notification .所有三个位置都应与应用的主包名称匹配。
