获得异常的Fcm集成

Question

我正在进行FCM集成,但得到了java.lang.ClassNotFoundException: Didn't find class "service.MyFirebaseMessagingService" on path: DexPathList[[zip file "/data/app/com.rk.servicepractise-2/base.apk"],nativeLibraryDirectories=[/vendor/lib64, /system/lib64]]

我已经搜索过但没有得到正确的解决方案,请检查下面的代码,让我知道我在哪里做错了？

请检查我classes 和manifest使用文件gradle,请帮我出短距离这个问题.
我的第一个类是MyFirebaseInstanceIDService扩展FirebaseInstanceIdService类

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
    }
}

还有一个类Fcm扩展FirebaseMessagingService类如下: -

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());
    }
}

以下是我的Manifest文件条目 Fcm

<application>
.
.
.
.

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

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

    </application>

而gradle其中我使用它如下模块:应用程序: -

apply plugin: 'com.android.application'

android {
.
.
.
.
.

}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.google.firebase:firebase-messaging:9.8.0'

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

build.gradle敌人Project:ProjectName

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath 'com.google.gms:google-services:3.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

以下是我得到的例外情况: -

只需在文件中添加点(.)即可. ServiceMainfest

换句话说,以下是诀窍:

<service android:name=".service.MyFirebaseMessagingService">
