昨天谷歌在Google I/O上展示了基于新Firebase的新通知系统.我在Github上尝试了这个新的FCM(Firebase云消息传递)示例.
尽管我已声明了特定的drawable,但通知的图标始终是ic_launcher
为什么？以下是处理邮件的官方代码
public class AppFirebaseMessagingService extends FirebaseMessagingService {
/**
* Called when message is received.
*
* @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
*/
// [START receive_message]
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// 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 …android push-notification googleio firebase firebase-cloud-messaging
在我MainActivity的日志中,我可以看到使用的令牌FirebaseInstanceId.getInstance().getToken(),它显示生成的令牌.但似乎在我 MyFirebaseInstanceIDService扩展到的地方FirebaseInstanceIdService,onTokenRefresh()没有被调用,在这个函数中,据说令牌最初是在这里生成的.我需要打电话给我,sendRegistrationToServer()这就是为什么我想知道它为什么不进入的原因onTokenRefresh().
这是我的代码
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
sendRegistrationToServer(refreshedToken);
}
}

我已经从服务器向用户发送FCM通知.它工作正常(直到api 25),但在奥利奥,当应用程序没有在后台(服务已关闭)(或)完全关闭.我没有得到任何FCM通知在这种情况但在Whatsapp工作正常.这里我附上了FCM代码

versionName "1.0" …我正在尝试使用FireBase云消息传递.我收到一个令牌,但它没有从控制台收到任何通知.这是我的清单:

</application>
而我的代码几乎与样本相同:
public class NotificationService extends FirebaseMessagingService {
private void …我正在我的应用程序中实现FCM(Firebase消息服务).这里似乎都没问题,除非app处于后台状态我无法提取预期的通知数据.
基于概念:FCM中有两种类型的消息:
display-messages:这些消息仅在您的应用处于前台时才有效.
数据消息:即使您的应用处于后台,这些消息也能正常工作当我们的应用处于后台时,Android会将通知消息定向到系统托盘.
处理数据消息时,您的通知应具有click_action ="YOUR_ACTION"字段.
我的信息会是这样的:
{
"data": {
"body": "here is body",
"title": "Title",
"click_action": "YOUR_ACTION"
},
"to": "ffEseX6vwcM:APA91bF8m7wOF MY FCM ID 07j1aPUb"
}
活动将显示清单文件将如下所示的消息:
<activity
android:name=".NotificationActivity"
android:screenOrientation="portrait"
android:theme="@style/Theme.AppCompat.Dialog"
android:windowSoftInputMode="stateHidden" >
<intent-filter>
<action android:name="YOUR_ACTION" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
点击通知后,它将重定向到我的NotificationActivity.在我的NotificationActivityin onCreate和onNewIntent方法中,我使用这种方式提取消息:
Bundle bundle=getIntent().getExtras();
if(bundle!=null) {
for (String key : bundle.keySet()) {
Object value = bundle.get(key);
Log.d("DATA_SENT", String.format("%s %s (%s)", key,
value.toString(), value.getClass().getName()));
}
} …
