Android firebase通知不起作用

Question

我想在我的Android-App中实现Firebase-Messaging插件。 我想我遵循了所有必要的步骤。但它不起作用。

构建应用：模块

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "26.0.0"
    defaultConfig {
        applicationId "com.example.dev.app"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    packagingOptions {
        exclude 'META-INF/NOTICE' // will not include NOTICE file
        exclude 'META-INF/LICENSE' // will not include LICENSE file
        // as noted by @Vishnuvathsan you may also need to include
        // variations on the file name. It depends on your dependencies.
        // Some other common variations on notice and license file names
        exclude 'META-INF/notice'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/license'
        exclude 'META-INF/license.txt'
    }
}

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:design:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:support-v4:25.3.1'
    compile 'com.android.volley:volley:1.0.0'
    compile 'com.fasterxml.jackson.core:jackson-core:2.5.3'
    compile 'com.fasterxml.jackson.core:jackson-annotations:2.5.3'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.5.3'
    compile 'com.google.android.gms:play-services-maps:11.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.google.firebase:firebase-core:11.0.2'
    compile 'com.google.firebase:firebase-messaging:11.0.2'
}
apply plugin: 'com.google.gms.google-services'

构建应用：项目

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'com.google.gms:google-services:3.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

AndroidManifest

</manifest>

FirebaseIDService

public class FirebaseIDService extends FirebaseInstanceIdService {
    private static final String TAG = "FirebaseIDService";

    @Override
    public void onTokenRefresh() {
        // Get updated InstanceID token.
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG, "Refreshed token: " + refreshedToken);

        // TODO: Implement this method to send any registration to your app's servers.
        sendRegistrationToServer(refreshedToken);
    }

    /**
     * Persist token to third-party servers.
     *
     * Modify this method to associate the user's FCM InstanceID token with any server-side account
     * maintained by your application.
     *
     * @param token The new token.
     */
    private void sendRegistrationToServer(String token) {
        // Add custom implementation, as needed.
    }
}

MyFirebaseMessagingService

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    private static final String TAG = "FCM Service";
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO: Handle FCM messages here.
        // If the application is in the foreground handle both data and notification messages here.
        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated.
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
    }
}

我已下载google-services.json enter image description here

从firebase控制台发送消息 enter image description here

但我没有收到任何通知。
