执行推送通知的步骤-适用于Android的Firebase云消息传递教程

steps for perform push notification - Firebase Cloud Messaging Tutorial for Android

1. 转到firebase控制台并创建一个新项目.
2. 现在输入您的应用名称并选择您的国家/地区.
3. 现在单击将Firebase添加到您的Android应用".
4. 现在您必须输入项目包名称，然后单击添加APP".
5. 点击添加应用后，您将获得google-services.json文件.

在应用程序方面

1. 现在回到您的android项目.转到应用程序文件夹并粘贴google-services.json文件

2. 现在转到您的根目录build.gradle文件并添加以下代码.

1. Now come back to your android project. Go to app folder and paste google-services.json file

2. Now go to your root level build.gradle file and add the following code.

a.添加此行classpath'com.google.gms:google-services:3.0.0'

a. Add this line classpath 'com.google.gms:google-services:3.0.0'

b.添加此行编译'com.google.firebase:firebase-messaging:9.0.0'

b. Add this line compile 'com.google.firebase:firebase-messaging:9.0.0'

现在同步您的项目.

创建一个名为MyFirebaseInstanceIDService.java的类，并编写以下代码:

Create a class named MyFirebaseInstanceIDService.java and write the following code:

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

    private static final String TAG = "MyFirebaseIIDService";

    @Override
    public void onTokenRefresh() {

        //Getting registration token
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();

        //Displaying token on logcat 
        Log.d(TAG, "Refreshed token: " + refreshedToken);

    }

    private void sendRegistrationToServer(String token) {
        //You can implement this method to store the token on your server 
        //Not required for current project 
    }
}

现在创建MyFirebaseMessagingService.java并编写以下代码:

Now create MyFirebaseMessagingService.java and write the following code:

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

/**
 * 
 */

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMsgService";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        //Displaying data in log
        //It is optional 
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());

        //Calling method to generate notification
        sendNotification(remoteMessage.getNotification().getBody());
    }

    //This method is only generating push notification
    //It is same as we did in earlier posts 
    private void sendNotification(String messageBody) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle("Firebase Push Notification")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0, notificationBuilder.build());
    }
}

现在，我们必须在AndroidManifest.xml文件中定义以上服务.因此，请按照以下说明进行清单和修改.

Now we have to define the above services in our AndroidManifest.xml file. So go to manifest and modify as follows.

<!-- Adding Internet Permission -->

<uses-permission android:name="android.permission.INTERNET"/>
<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <!-- 
        Defining Services
    -->
    <service
        android:name=".MyFirebaseMessagingService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT"/>
        </intent-filter>
    </service>

    <service
        android:name=".MyFirebaseInstanceIDService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
        </intent-filter>
    </service>
</application>

最后

转到firebase控制台，然后选择您创建的应用.从左侧菜单中选择通知.单击新消息.输入消息，选择单个设备并粘贴您复制的令牌，然后单击发送.与我在视频中所做的相同，然后检查您的设备

Go to firebase console and select the app you created. From the left menu select notification. Click on new message. Enter message, select single device and paste the token you copied and click on send. The same as I did on the video, and check your device
