FirebaseInstanceIdService getToken返回null

标签： android firebase firebase-cloud-messaging

我正在尝试将FCM通知添加到我的应用中，但出于某种原因

FirebaseInstanceId.getInstance().getToken();

返回null。

由于我没有得到任何堆栈跟踪，我最好的猜测是FirebaseInstanceIdService不能正常工作

  • Google Play服务版：9.6.1
  • Firebase-messaging版本：9.6.1
  • 从FirebaseConsole添加了json配置文件（在其中包含2个客户端的尝试单个文件，一个用于调试，一个用于发布版本）和每个用于各自构建的2个文件

我在我的模块gradle脚本底部应用了google服务插件 在项目根gradle脚本中包含谷歌服务

从官方文件中创建了2项服务：

public class MyFirebaseInsanceIDService  extends FirebaseInstanceIdService {

private static final String TAG = "MyFirebaseIIDService";

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    PreferencesHelper.putSharedPreferencesString(Constants.User.PUSH_NOTIFICATIONS, refreshedToken);

    Log.e("TOKEN", "Token: " + FirebaseInstanceId.getInstance().getToken());
}

}

  • 请注意，我在根应用程序代码中使用tools:node="replace"。 是否有可能FirebaseInstanceIdService未添加到清单中，因为它与我的FirebaseInstanceService具有相同的意图过滤器，因此没有被调用？

所以我的问题是，官方文档或我的实现中是否存在错误导致实例令牌为空？

通过挖掘FCM的旧实现并生成清单之后，我现在可以说清单合并就是问题。

此问题的解决方法是将这些类手动添加到应用程序清单

我在进行迁移时遇到了问题，但是我没有收到任何通知。要解决此问题，并且如果您的GCM正常运行，请不要忘记在获得Firebase令牌时包含您的发件人ID。要查阅此ID，您必须导航到Firebase项目并单击“项目名称”。单击设置图标，然后选择＆＃34;项目设置＆＃34;菜单选择＆＃34;可能消息＆＃34;选项卡并在页面上使用发件人ID。

当说要编码时：

     token = FirebaseInstanceId.getInstance().getToken();

你必须使用它：

     token = FirebaseInstanceId.getInstance().getToken("YOUR_SENDER_ID", "FCM");

它对我有用，我希望这可以帮助你;）

这对我有用：

String token = FirebaseInstanceId.getInstance().getInstanceId().getResult().getToken();

答案 3 :(得分：-1)

首先genarate“google-services.json”并在你的android studio中添加此文件就像这个projectFolder / APP / google-services.json

将classpath添加到顶级build.gradle 

 dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        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
    }

在app的build.gradle中添加以下插件和依赖项

apply plugin: 'com.google.gms.google-services'
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile 'com.google.firebase:firebase-core:9.4.0'
    compile 'com.google.firebase:firebase-messaging:9.4.0'
}

在您的java文件中添加以下Firebase服务

FirebaseIDService.java 

package com.galleonsoft.firebase.push;

import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;

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);
    }

    private void sendRegistrationToServer(String token) {
        // Add custom implementation, as needed.
    }
}

MyFirebaseMessagingService.java 

package com.galleonsoft.firebase.push;

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 = "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());
    }
}

在AndroidMainifest.xml文件中添加服务

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

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