Question

我正在尝试根据GCM升级谷歌推送通知的旧解决方案，在其他版本中GCM已被弃用，建议使用com.google.android.gms.gcm.GoogleCloudMessaging使用

我没有在新版本中找到替代方法的方法很少，如

GCMRegistrar.setRegisteredOnServer（context，true）;
GCMRegistrar.getRegistrationId（本）;
GCMRegistrar.register（this，SENDER_ID）;
GCMRegistrar.isRegisteredOnServer（本）
GCMRegistrar.onDestroy（本）;

此外，我指的是一篇旧文章，其中有一项服务延伸GCMBaseIntentService com.google.android.gcm.GCMBaseIntentService，而不是新版本

任何人都可以帮我升级以下代码。

import static com.androidhive.pushnotifications.CommonUtilities.SENDER_ID;
import static com.androidhive.pushnotifications.CommonUtilities.displayMessage;
import android.app.Notification;
import android.app.NotificationManager; import android.app.PendingIntent;
import android.content.Context; import android.content.Intent; 
import android.util.Log;

import com.google.android.gcm.GCMBaseIntentService;

public class GCMIntentService extends GCMBaseIntentService {

    private static final String TAG = "GCMIntentService";

    public GCMIntentService() {
        super(SENDER_ID);
    }

    /**
    * Method called on device registered
    **/
    @Override
    protected void onRegistered(Context context, String registrationId) {
        Log.i(TAG, "Device registered: regId = " + registrationId);
        displayMessage(context, "Your device registred with GCM");
        Log.d("NAME", MainActivity.name);
        ServerUtilities.register(context, MainActivity.name, MainActivity.email, registrationId);
    }

    /**
    * Method called on device un registred
    * */
    @Override
    protected void onUnregistered(Context context, String registrationId) {
        Log.i(TAG, "Device unregistered");
        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("price");

        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);
        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);
        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);
        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, MainActivity.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);      
    }
}

考虑迁移到Firebase Cloud Messaging（FCM）

自2018年4月10日起，Google已弃用GCM。 GCM服务器和客户端API已被弃用，并将于2019年4月11日删除。将GCM应用程序迁移到Firebase Cloud Messaging（FCM），它继承了可靠且可扩展的GCM基础架构以及许多新功能。
