Firebase云消息传递Android项目无法发送推送通知

标签: android firebase push-notification firebase-cloud-messaging

我正在尝试开发一个应用程序,其中服务器必须每隔5秒向运行该应用程序的所有Android设备发送通知。我决定使用(Google)Firebse Cloud Messaging发送通知,所以我先尝试了指南的示例项目

https://firebase.google.com/docs/notifications/android/console-audience

但我不能让它发挥作用。我遵循了所有指示。我已发布我使用的代码。我还做了文件 - >项目结构 - >通知 - >选中了Google Cloud Messaging 框。我在android 5设备上尝试了该应用程序。

当我打开Firebase控制台并发送通知时,我会在日志中看到刷新的令牌(来自MyFirebaseInstanceIDService类,方法onTokenRefresh()),但是当我再次运行它时,会发送通知给通过复制和粘贴令牌的单个设备,没有任何反应。此外,当我从控制台向用户细分发送通知时,不会再发生任何事情。

我也尝试过来自同一网站的Firebase相应的ios示例项目,它适用于iphone(所有通知都已发送)。我在这里遗漏了什么?

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

private static final String TAG = "MyFirebaseIIDService";

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    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.
}
}

MyFirebaseMessagingService:

public class MyFirebaseMessagingService extends FirebaseMessagingService {

private static final String TAG = "MyFirebaseMsgService";

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    Log.d(TAG, "From: " + remoteMessage.getFrom());

    //Toast.makeText(getApplicationContext(),"FROM "+remoteMessage.getFrom(),Toast.LENGTH_LONG).show();
    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
        Log.d(TAG, "Message data payload: " + remoteMessage.getData());
        //Toast.makeText(getApplicationContext(),"MESSAGE: "+remoteMessage.getData(),Toast.LENGTH_LONG).show();
    }

    // Check if message contains a notification payload.
    if (remoteMessage.getNotification() != null) {
        //MainActivity.TestMethod();
        Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
        //Toast.makeText(getApplicationContext(),"MESSAGE: "+remoteMessage.getData(),Toast.LENGTH_LONG).show();
    }

    // Also if you intend on generating your own notifications as a result of a received FCM
    // message, here is where that should be initiated. See sendNotification method below.
 sendNotification(remoteMessage.getNotification().getBody());
}

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.drawable.ic_stat_ic_notification)
            .setContentTitle("FCM Message")
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

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

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}

主要活动:

public class MainActivity extends AppCompatActivity {

private static final String TAG = "MainActivity";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (getIntent().getExtras() != null) {
        for (String key : getIntent().getExtras().keySet()) {
            String value = getIntent().getExtras().getString(key);
            Log.d(TAG, "Key: " + key + " Value: " + value);
        }
    }

    Button subscribeButton = (Button) findViewById(R.id.subscribeButton);
    subscribeButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // [START subscribe_topics]
            FirebaseMessaging.getInstance().subscribeToTopic("news");
            // [END subscribe_topics]

            // Log and toast
            String msg = getString(R.string.msg_subscribed);
            Log.d(TAG, msg);
            Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
        }
    });

    Button logTokenButton = (Button) findViewById(R.id.logTokenButton);
    logTokenButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // Get token
            String token = FirebaseInstanceId.getInstance().getToken();

            // Log and toast
            String msg = getString(R.string.msg_token_fmt, token);
            Log.d(TAG, msg);
            Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
        }
    });
}
}

和build.gradle(项目消息传递):

    // Top-level build file where you can add configuration options commonto             `all sub-projects/modules.`

buildscript {
    repositories {
        jcenter()
        mavenLocal()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'
        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
    }
}

allprojects {
    repositories {
        jcenter()
        mavenLocal()
    }
}

和build.gradle(模块应用):

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"

    defaultConfig {
        applicationId "com.google.firebase.quickstart.fcm"
        minSdkVersion 15
        targetSdkVersion 24
        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 'LICENSE.txt'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    // Testing dependencies
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.1'
    androidTestCompile 'com.android.support.test:runner:0.2'
    androidTestCompile 'com.android.support:support-annotations:24.2.0'
    compile 'com.android.support:appcompat-v7:24.2.0'
    compile 'com.google.firebase:firebase-messaging:9.4.0'
    compile 'com.google.firebase:firebase-core:9.4.0'
    compile 'com.google.android.gms:play-services-gcm:9.4.0'
    compile 'com.android.support:design:24.2.0'
}

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

您可能正在尝试在应用程序处于前台时收到通知。请确保它在后台并再试一次。否则,当您的应用程序处于前台时,您需要按照该过程获取通知。

来自Firebase文档: JSFiddle

  

Firebase通知的行为会有所不同,具体取决于接收应用的前景/背景状态。如果您希望前景应用程序接收通知消息或数据消息,则需要编写代码来处理onMessageReceived回调。

发送通知消息:https://firebase.google.com/docs/cloud-messaging/android/receive

  

发送通知消息

     
      
  1. 在目标设备上安装并运行应用程序。
  2.   
  3. 确保该应用位于设备的后台。
  4.   
  5. 打开Firebase控制台的“通知”标签,然后选择“新消息”。
  6.   
  7. 输入消息文本。
  8.   
  9. 为邮件目标选择单个设备。
  10.   
  11. 在标有FCM注册令牌的字段中,输入您在本指南前一部分中获得的注册令牌。
  12.

我终于找到了问题所在。似乎某个json文件不适合示例项目。当您在Firebase控制台上创建项目时,它会生成一个json文件,该文件应该被下载并放置到app文件夹中。当我为自己的应用程序(而不是示例项目)创建项目并重新执行所有操作(并将控制台生成的json文件放在app文件夹中)时,它运行正常。
