[英]Not show push notification (Firebase Cloud Message) on status bar when app is not running
在AndroidManifest.xml
<service
android:name=".CustomFirebaseInstanceIDService"
android:exported="true">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
<service
android:name=".CustomFirebaseMessagingService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
我的服务:
import android.util.Log
import com.google.firebase.messaging.FirebaseMessagingService
import com.google.firebase.messaging.RemoteMessage
import org.tokend.template.BuildConfig
class CustomFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage?) {
if (remoteMessage?.data?.isNotEmpty()!!) {
val payloadData: Map<String, String> = remoteMessage.data
PushNotificationService.showNotification(applicationContext, payloadData["title"]!!, payloadData["body"]!!)
}
// Check if message contains a notification payload.
remoteMessage.notification?.let {
val notificationTitle : String? = it.title
val notificationBody: String? = it.body
PushNotificationService.showNotification(applicationContext, notificationTitle!!, notificationBody!!)
}
}
并显示推送:
object PushNotificationService {
val TAG = PushNotificationService::class.java.name
val CHANNEL_ID = "channelId"
val NOTIFICATON_ID = 1
fun showNotification(context: Context, title: String, body: String) {
val intent = Intent(context, SignInActivity::class.java).apply {
this.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
}
val pendingIntent: PendingIntent = PendingIntent.getActivity(context, 0, intent, 0)
val builder = NotificationCompat.Builder(context, CHANNEL_ID)
.setSmallIcon(R.mipmap.ic_launcher)
.setLargeIcon(BitmapFactory.decodeResource(context.getResources(),
R.mipmap.ic_launcher))
.setContentTitle(title)
.setStyle(NotificationCompat.BigTextStyle().bigText(body))
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
// Set the intent that will fire when the user taps the notification
.setContentIntent(pendingIntent)
.setAutoCancel(true)
// Show the notification
with(NotificationManagerCompat.from(context), {
// NOTIFICATON_ID is a unique int for each notification that you must define
this.notify(NOTIFICATON_ID, builder.build())
})
}
所以:
当服务器发送数据或通知并且应用程序运行并在前台运行时,方法onMessageReceived
成功调用和成功在状态栏(顶部)中显示推送通知(标题和正文)
当服务器发送数据或通知并且应用程序运行并最小化然后方法onMessageReceived
成功调用和成功在状态栏中显示推送通知(在顶部)
但是,当服务器发送数据或通知并且应用程序未运行时,则不要调用onMessageReceived
方法,也不会在状态栏上显示推送通知。
但是当应用程序未运行时,我需要在状态栏上显示推送通知。
我通过 Python 脚本向我的 android 设备发送数据消息:
import firebase_admin, sys
from firebase_admin import credentials, messaging
message = messaging.Message(
data={
"title": "Test data",
"body": "Body of long test text of data test long body message for type data"
},
token=sys.argv[1],
)
response = messaging.send(message)
PS 如果我从 Firebase 控制台发送消息,那么当应用程序未运行时,成功在状态栏上显示推送通知。
尝试只发送data
负载(没有notification
负载)它应该总是调用onMessageReceived
。 还可以尝试添加优先级(my.js 示例):
const payload = {
data: {
title: 'finalTitle',
body: 'message',
},
android:{
priority: 'high'
},
topic: channel
};
admin.messaging().send(payload)
