使用应用程序时(在前台运行)请勿调用推送通知 [英] Don't invoke push notification when app is being used (running in foreground)
问题描述
在我的Android应用中,我通过Firebase Cloud Messaging接收了推送通知.通知工作完全正常,唯一的问题是我不希望在应用程序运行时接收通知.当用户使用ap时,我已经在内部显示了通知,因此推送通知既多余又烦人.以下是有关我如何调用推送通知的代码:
In my android app, I receive push notifications via Firebase Cloud Messaging. The notifications work completely fine, the only problem is that I don't want to receive notifications when the app is running. When the user is using the ap, I am already displaying the notification internally so the push notification is redundant and annoying. Below is the code on how I invoke push notification:
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_stat_name)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setAutoCancel(true)
.setVibrate(pattern)
.setLights(Color.BLUE,1,1)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(notificationId, notificationBuilder.build());
}
我在此链接上尝试了该解决方案,但由于我确实希望收到通知,因此在我的情况下它不起作用当应用程序在后台或被杀死时.另外,在应用程序启动时将布尔值设置为true
,在应用程序关闭时将布尔值设置为false
似乎不是理想的解决方案.必须有更好的方法,但是我找不到.任何帮助将不胜感激.
I tried the solution on this link, and it won't work in my case because I do want the notification when the app is in the background or killed. Also setting a boolean to true
when the app starts and false
when the app is closed does not seem like an ideal solution. There has to be a better way but I can't find it. Any help would be appreciated.
推荐答案
我要做的是在Application类中使用ActivityLifeCycleCallbacks
What I do is use ActivityLifeCycleCallbacks in your Application class
class MyApplication:Application(){
companion object {
private var activitiesOpen = 0
var displayActivity:String?= null
private set
fun isAppOpen() = activitiesOpen > 0
}
private val activitiesListener = object : ActivityLifecycleCallbacks{
override fun onActivityPaused(activity: Activity?) {
--activitiesOpen
displayActivity = null
}
override fun onActivityResumed(activity: Activity?) {
activitiesOpen++
displayActivity = if(activity != null)
activity::class.simpleName else null
}
override fun onActivityStarted(activity: Activity?) {
}
override fun onActivityDestroyed(activity: Activity?) {
}
override fun onActivitySaveInstanceState(activity: Activity?, outState: Bundle?) {
}
override fun onActivityStopped(activity: Activity?) {
}
override fun onActivityCreated(activity: Activity?, savedInstanceState: Bundle?) {
}
}
}
现在,您可以在 onMessageReceived 中查看它了.
Now in your onMessageReceived you can check it out like this.
if (MyApplication.isAppOpen() &&
DashboardActivity::class.simpleName?
.equals(MyApplication.displayActivity) ?: false) {
// you can eliminate the last condition if you wish
playAlertTone(context) // or whatever
} else {
// your notification building code
}
代码在kotlin中,希望您不会有问题.
The code is in kotlin, I hope you'll have no problem with it.
