透過Google的Firebase來實現推播

使用Firebase只要你有Google帳號就可以用囉

 

Step 1:

https://firebase.google.com/

先到Firebase的網站登入您的Google帳號

登入後會看到這畫面，按下GET STARTED就可以開始啦

 

Strp 2:

開始新增專案，專案是很重要的可以讓你好好管理你所要推播的對象是誰

 

輸入你所想要的專案名稱，選擇你所在的國家

 

Step 3:

這一頁就是你這個專案底下所管理的東西，今天我們要利用的裝置是Android

選擇將Firebase加入您的Android 應用程式

Android 套件名稱要到你的Android Studio裡面，打開app層級的build.gradle找到applicationId

那個就是要填到Android 套件名稱的

Step 4:

按照他的教學下載google-services.json放到app資料夾裡面

記得!!!如果你換了另一個Android Studio的專案，要重新Step 3~4的步驟

不能直接把google-service.json這個東西複製到其他的專案裡面!!

按照他的教學到不同的build.gradle新增

 

這個是專案層級的

第二步就直接把下面這行貼到最底端就好啦~

apply plugin: 'com.google.gms.google-services'

 

但是在應用程式階層的這個build.gradle還有東西要新增

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.0-beta5'
    compile 'com.google.firebase:firebase-core:11.0.2'
    compile 'com.google.firebase:firebase-messaging:11.0.2'
    compile 'com.firebase:firebase-jobdispatcher:0.6.0'
    testCompile 'junit:junit:4.12'
}

我也不知道為何在剛剛那個頁面他沒有說明

但是記得要新增這兩行，還有記得要把Android Studio的SDK Manager裡面的東西都安裝到最新版

記得貼完之後要按Sync now

 

Step 5:

新增一個Service我把它命名為MyFiewbaseInstanceIDService

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService{
    private static final String TAG = "MyFirebaseIIDService";
    @Override
    public void onTokenRefresh() {       
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG, "Refreshed token: " + refreshedToken);
        sendRegistrationToServer(refreshedToken);
    }
    private void sendRegistrationToServer(String token) {
        // TODO: Implement this method to send token to your app server.
    }
}

 

新增另一個Service命名為MyFirebaseMessagingService

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMsgService";

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        Log.i("Service", "onMessageReceived: " + remoteMessage.getFrom());
        if (remoteMessage.getData().size() > 0) {
            Log.i("Service", "" + remoteMessage.getData());
        }
        if (remoteMessage.getNotification() != null) {
            Log.i("Service", "" + remoteMessage.getNotification().getBody());
            sendNotification(remoteMessage.getNotification().getBody());
        }
    }

    @Override
    public void onMessageSent(String s) {
        super.onMessageSent(s);
        Log.i("Service", "onMessageSent" + s);
    }

    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 /* Request code */, 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("App")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
    }
}

 

Step 6:

到AndroidManifest.xml

新增meta-data以及service

<!-- Set custom default icon. This is used when no icon is set for incoming notification messages.
     See README(https://goo.gl/l4GJaQ) for more. -->
<meta-data
    android:name="com.google.firebase.messaging.default_notification_icon"
    android:resource="@drawable/ic_stat_ic_notification" />
<!-- Set color used with incoming notification messages. This is used when no color is set for the incoming
     notification message. See README(https://goo.gl/6BKBk7) for more. -->
<meta-data
    android:name="com.google.firebase.messaging.default_notification_color"
    android:resource="@color/colorAccent" />

<service
    android:name="com.xxxxxx.user.MyFirebaseMessagingService">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

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

 

Step 7:

然後App的部分就差不多了

到Firebase裡面選擇你想要推播的內容

在訊息文字填上你所想要推播給使用者看的內容

然後按下傳送訊息就完成了~~

 

Step 8:

推播的速度其實算很快~~我按下傳送訊息不到五秒手機這邊就收到通知了

其實步驟看起來很多但是一步一步跟著做其實很簡單的
