Hey guys,
Tried searching for this, but nada.
Anyone else having issues with your phone being idle but powered on ans upon bringing on the screen you receive a google talk notification that's old? Is been happening to me lately, and I can't tell if it's the phone or the fact that my desktop version is intercepting the message and preventing the phone notification.
I'm tempted to no longer use the desktop built in gmail version, but I wanted to see if others are having similar issues.
Thanks in advance!

Can't guarantee this, but I have a feeling it may have something to do with the phone letting the Google talk process close when the phone is in it's sleep state. I've noted that I keep having to re sign in to gtalk when I wake up my phone and suspect that it is an issue with the horrible multitasking that HTC has bundled into sense 4.0.
I assume both of you also get delayed notifications with push email using the native Gmail app? I also frequently get logged out of Google Talk when I put the phone in standby mode. When I am logged out of Google Talk, my push emails are delayed in the Gmail app until I log back into Google Talk.
So it seems to be some problem of getting disconnected from google services when the phone is asleep.
I don't think i've been getting delayed notifications, but I do notice that my chat gets out of order a lot. My replies will be above whoever is talking to me no matter what order each was sent in.
Almost every phone that comes out gets a google talk going eventually so there is lots out there, but each phone has it's own issues. Here is a thread that was pretty good from the Galaxy Nexus Forums.
http://forum.xda-developers.com/showthread.php?t=1400367
With the HOX I have had issues with Google Talk not working great when the wifi is dropping, so this might be part of the wifi issue that pretty much everybody is having with this phone. The wifi stays connected but seems to go to sleep so your phone only gets the notification once it is woken up. Try turning off the wifi and seeing if you have the same problem.
As for Google Talk, there are some oddities that go along with using it on multiple devices. Here is some stuff I figured out playing around with it on multiple devices and computers at the same time. (I posted this in the GN forums as well)
"Google Talk is my main means of communication it seems so I have played with it a lot. Here are my observations.
1. To keep it "up" all the time in the Talk App hit the menu button (three dots now) >settings>uncheck automatic away status. Also make sure your phone has automatic syncing turned on for your gmail account: Setting>Accounts and Sync>ON (for your chat gmail address anyway). Additionally make sure your mobile data is turned on if you are ever off wifi: Settings>More>Mobile networks>Data Enabled (checked to turn on)
2. You can have up to 6 devices linked to your talk account at once, after that they just stop working.
3. When you receive a IM it appears on both your phone and your gmail account. If you start typing on the gmail account (or G+) it hijacks the whole session and you phone no longer gets the notifications, but the conversation still shows up on the chat window on the phone. When you are done with the IM session make sure you close the window on gmail (or G+) and send one last message from your phone or tablet to take the session back over, if you don't your phone will not receive future chat notifications. You can also just log out of your gmail/G+ session and it will automatically return everything to your phone/tablet but who ever does that?
4. To figure out how it all worked and tinker with it I use both of my gmail accounts and chat back and forth with them. You can do it from separate browsers or just open an incognito window in Chrome and log into your other gmail account. I would recommend this so you can see all of this stuff in practice.
Good Luck, hope this helps"
Gtalk and gmail delays
Hi all,
I have performed tests and discovered that if i disable WiFI and only use the phone's data connection "4g" or LTE that i receive all my messages with no problem even when the phone locks/goes to sleep. However if i leave wifi turned on, within 5-10 seconds i stop receiving them and will only receive them when i wake up the phone/unlock or wait for the delay which can be anywhere from 5-15 mins.
Trying to figure out a way to by pass this, but can't seem to figure it out. I don't want to keep my wifi off when i'm at work or home so i don't use data as i have 3GB and not unlimited so it kind of sucks that i have to keep wifi off for now. Any thoughts/ideas would be great, thanks.

This. I have issues with timely/accurate reception of notifications from GV. I only use my account for voicemail, but typically I only get voicemail notifications if I open the actual application (which I do because my gmail account receives an email notification now, as well). Sometimes I notice GV as a running task, but often times not, so to me it seems that (possibly) multitasking or some other form of process management in ICS or Sense is not prioritizing the GV process and it's associated actions. I dont mind the aggressive multitasking, but it would be nice to have the option of protecting some processes, such as GV.
I removed google + app completely with titanium backup, and the problem is gone., I get the messages immediately
Push Notifications Fixer can fix it

I'm running the latest Viper, I've never had an issue receiving or sending msgs. The only time the phone won't alert me is if I am actively typing in the browser window.
I'll note though that I never have wifi on, it's always on the mobile network.

I tried everything not even this works for me
Same problem, screen off - phone disconnects, unlock the phone - messages start to appear
Same problem on 2 different phones and 2 different numbers
I don't use G Talk, but I see the same thing with G Voice. I almost never get voicemail notifications on my HOX (they show up instantly on my old GNex). I blame Sense (for this and other things).
Same problem, but with Nexus 4 when I am on WiFi. With data connection, it works without problems.

Hi everyone,
Are you experiencing delayed push notifications from GTalk/Hangouts, GMail, Whatsapp (partial fix), Facebook, Play Store web install, etc? If so, then this app its for you!!
It's FREE! No banners. No ads. Please consider donating to the developer (link in the app).
This app work for EVERY phone. ROOT is NOT required
Root version here: http://forum.xda-developers.com/showthread.php?t=2142503
This app basically keep alive the push connection on your phone. It avoid the tcp connection timeout that can occurs on some wifi routers or on some mobile carriers.
You will always receive instantly push notifications.
● Why were my notifications delayed in the first place?
Apps using Google's push service (Hangouts, Gmail, Facebook Messenger, e.g.) connect your phone to Google’s servers via one TCP connection (on port 5228).
To keep this connection alive, Android uses a periodic heartbeat to prevent the connection from timing out. By default, this heartbeat occurs every 15 minutes on wifi and every 28 minutes on a mobile data connection.
This is problematic because most Wi-Fi routers and mobile carriers will automatically terminate this connection after a short time of inactivity.
Because your phone is not aware that this connection was externally closed, you will not receive push notifications until this connection is reestablished when the next heartbeat is sent.
● How does PNF solve this problem?
Every x minutes it invoke an android activity that will send an heartbeat network packet on the push connection. Sending an heartbeat every 5 minutes should be enough to always keep the connection alive and all your push notifications will be instantly.
The battery should not be much impacted over a day.

FAQ
Q: Does this app drain battery in background? Does lowering the heartbeat interval too much cause more battery drain?
A: It should have not a big impact on the battery during your daily use. I recommend hearbeat set to 5 minutes, it should be enough to make you receive instantly notifications.
Q: What does mean "set the heartbeat to x minutes" ?
A: It means only that android will send a network packet over the push connection every x minutes instead of the default 15/28 minutes to keep alive that connection. It does NOT mean that you receive push notification every x minutes. Notifications are instantly if the push connection is alive.
Q: Why Whatsapp messages are still delayed sometimes?
A: Whatsapp, and some others apps, don't completely rely on google push service (GCM). Those apps start their own connection when you open the application, and the messages come through this connection. The heartbeat is sent by android only on the push connection on the port 5228, and so it only keep-alive that particular connection. Blame those apps that doesn't have a keep-alive mechanism for their connection or that doesn't use full push messaging.
A workaround for whatsapp is to swipe it away from the recent apps when your finished a chat session. In this way it's connection is dropped and you will be notified of new messages through google push notifications.

How?
Hi, Im using your application, the root one.
But I'm interested in how this one works.
I recently developed an app that use GCM to send messages between devices.
If you can answer me... How do you send the heartbeat through an Activity? This can help a lot of people since Google don't do anything.
Thank you

Basically to trigger an heartbeat you only need those 2 lines (those are undocumented, I it discovered by decompiling GSF):
Code:
context.sendBroadcast(new Intent("com.google.android.intent.action.GTALK_HEARTBEAT"));
context.sendBroadcast(new Intent("com.google.android.intent.action.MCS_HEARTBEAT"));
where context is the application context.
Those intents will be "catched" by GoogleServicesFramework (GSF) that will physically send the heartbeat packet to the google servers. If an aswer come back instantly the push connection is alive, otherwise if in 60 seconds there is no answer back, GSF will initiate a new push connection without to wait the next heartbeat.
The first intent is for Ice Cream Sandwhich and below "I think", while the second one is used in new android versions, should depend from the GSF version installed..But you can safety fire both, since one of the two won't just do anything.
Not sure if it is a good practice to place it inside an application, since if every developer will do that the battery will be killed. Maybe you can invoke that only in some situations.

Thanks a lot.
Your right, if every developer use it then can turn in to a problem.
I'm not going to use it, only in the start of the app if the users reports me problems. But first i'm going to suggest your application, i think is a better solution by the moment :good:.
Thanks for satisfy my curiosity.

Depends from your phone I think, just launch the recent apps list and remove / swype whatsapp from there..
On the Nexus phones there is a dedicated on screen button to open the recent app list, on some Samsung phone I think you can long press the home button.

Hi, I'am using the same method in my product.
Can we reach an agreement how to reduce the frequency of these intent calls?
I have no idea to realize any heartbeat timeout settings in my app (hard policy).
I can't listen for these intents cause it requires com.google.android.c2dm.permission.SEND permission that can't be acquired.
For example, can you send some additional broadcast intent (w/o permissions) when fire heartbeat?
I'll listen for it and reset own alarms to not to do the same action.

I have to check, there is an other intent directly fired by android which indicate that an heartbeat has been sent, you can listen that intent I think
I don't remember it right now what, I will check tomorrow maybe and will let you know

@dd00_xda
It seems there isn't an android system intent that you can listen to check if an heartbeat has been sent.
About your request to send some broadcast intent in my app, what will be the advantage for you? I mean, if you already need my app installed, then you don't need at all your own alarm..My app by default send and heartbeat every 5 minutes for example (the alarm will start every time a connection is made) and in that way the push connection is already alive..and every notification you app need to listen, it will always being received
Thanks very much for creating this app! I have a question about it.
I previously had a Samsung Galaxy S3 running Android 4.1.2. Push notifications worked fine over Wi-Fi when I was at home.
I have now switched to a Nexus 5 running Android 4.4. I'm still using the same router at home, but I'm getting an issue with notifications being delayed. Sometimes I will not get any notifications for a while, then a bunch will turn up at once from different apps.
Does the issue I've described sound like it's related to the problem that this app is designed to fix? If so, how come everything worked fine with my S3 with the same router?
Many thanks!

Do you have any recommendations of how I could troubleshoot this issue? I really don't know what the cause is - I just know it happens, and if it was a widespread issue with the Nexus 5 then a lot more people would be talking about this issue. I've only seen a handful of folks mentioning it.

if the phone disconnect from the wifi while the screen is off (happen also with only some routers sometimes), you usually should see the phone reconnect as soon as you wake the screen..if you pull down the notification bar and open the toggle switch, you should see the wifi icon orange (no connection to google server) and in few seconds become white again (connected).

I don't believe the Wi-Fi is disconnecting. I can ping the device when the screen has been off for ages and notifications do come in when the screen is off - they're just delayed and sometimes I don't get a notification at all, yet I'll get an email notification on my PC.

Hello, I have recently started having the same issues with my F6 not being able to load any background data as well. I believe your solution can lye within the apps that are being used. I Use a stock ROM too for my phone as there are no others out yet for it, and so, I also use ROM toolbox. This morning i could not for the life of me remember what i was doing to make the phone function this way, but remembered that i was dabbling with the DNS and server operations on ROM toolbox the night prier. I was a bit frustrated that there was no easy answer posted anywhere online (google) and had to figure it out myself.. (not so bad) . and since i have been constantly figuring out my ROMS abilities on STOCK I have acquired much knowledge for the F6 root and recover operations. IF you are having problems with any data being transmitted between apps and have been disabling ads through ROM toolbox be sure to make the right changes. For when you wake up to having no data app connection and your clearly connected to the internet it can become jarring.
hope this helps
Anyone having this issue. Not exactly sure what changed in my wifi setup but in the facebook and instagram apps photos in my feed wont load. When i switch over to mobile data or use the web page in the browser over wifi they load fine. For some reason my wifi does not play nice with instagram and facebook apps. This is on my galaxy s4 but have tried several different devices and they all have the same issue.
Has anyone run into this problem? Tried searched and found some people who had the opposite issue with it not loading over mobile data but havent found a thread on this. Thanks for any tips.
I am having the exact same issues. Any help would be greatly appreciated.

I am having the exact same issue, its seem to be a router problem, my newsfeed load fine one 4g and other wifi (i have a galaxy s2), but on my home wifi the newsfeed for facebook or instagram won't load, my sister is also experiencing the same problem with here galaxy S......any suggestions would be greatly appreciated.
FYI: i've tried restarting the router, upgrading the firmware which didn't work. also before i realized it was just the router i've tried force closing, clearing the cache and restarting the phone, i've also uninstall and reinstall the app several times.
I had a similar problem but I sorted it out today on my Nexus 4. My problem was, the default gateway on my phone was different from what it has to be for that specific wifi network.
In windows one can check the default gateway by running command prompt (cmd) and typing ipconfig.
On your phone you also have to check the advanced settings for that wifi network that you have problems with.
I set the Ip settings to static from DHCP and entered the default gateway values from my pc to my phone. You can also get another ip for your phone in that advanced settings tab if you think there may be an ip conflict but as I told, my problem was the differing default gateway values. I haven't changed the DNS which was google dns by default.
Key thing was the default gateway values for me and I'm hoping this will help many of you.

Ever since I upgraded OTA for marshmallow (i'm bone stock) I've had "connection" issues with multiple apps, regardless if i'm on wifi or 3g/4g.
The google sound search app (whats this song) says "you seem to be offline. Retry?
Google Voice when used pops up the screen saying "offline. check your connection" it does this too when I say "call x cell phone" unless i say "make a call first".
gmail app push notifications are non-existent. I don't email 80%+ of the time unless I manually sync.
Facebook app will constantly think I have no internet connectivity. I have to force updates which rarely works, or quit out of the app and reload.
Playstore does the same from time to time, giving messages about have no connection and to check it.
Voicemail will constantly give me errors: an error occurred, unable to connect to voicemail/visual voicemail. Paraphrasing here.
4 days ago I backed up everything over sftp to my computer and did a factory reset. This seemed to help for a little bit. The apps i've described above acted more normal, but since yesterday I'm having all the same issues again. I've never had any issue like this prior to the marshmallow update. Prior this i went into the settings and did a full reset of all network settings under ireless Controls or Wireless & Networks. that didn't help either

no system updates available. What gives, and what else can I provide? Should I report these as bugs to google/verizon?
I also have issues with apps like i heart radio, pandora, after my upgrade, it'll play 1 song or not at all and then after one song it closes out. I tried uninstalling, restarting the phone and then reinstalling but the same issues, and tis with all my audio streaming,.. help!?!?
I've been having the same issues as OP, as well as with Facebook. I'll have to close it out 5 or 6 times before it'll give me the latest posts. It keeps reverting back to May 6 and when opening comments get a message that i'm not connected even though i'm web browsing just fine. Seems to be an issue with the OS and apps.
The Facebook app is junk and notoriously buggy so that maybe your Facebook issue. On top of that its a huge memory hog and might as well be classified as spyware with it's endless permissions (and yes they do monitor you and EVERYTHING you do via the app for "advertising and product placement" purposes). I suggest ditching the app and just access Facebook via web browser. That alone has solved alot of issues for alot of people I know, even issues that seem unrelated to Facebook. Its supprising how miserably coded the Facebook app is and how many problems it is the source of, especially given it's such a large corporation. As for the other issues listed, I personally experience none of them on my Verizon S6. I stream music and video just fine on youtube, pandora and spotify. No connectivity issues... ever. Not with voicemail, google sound search, gmail, play store or any other apps. Do you have a task killer or other "battery optimizing" app that is turning off your wifi and/or mobile data without your knowledge. Thats my only thought.
Settings > Battery > More > Optimize Battery Usage.
Uncheck any apps that are having the problem and see if that helps
