For some reason my WhatsApp can't automatic hibernate. It's always in the 'Not hibernating automatically'. Whenever I manually make it hibernate, I don't receive any notifications or messages unless I open the app. I have the donation version, GCM is checked, keep notifications is checked, I have greenify enabled in both Accessibility and DeviceAdmin.
I do receive further notification and messages after I opened WhatsApp manually. Anyone else has experienced this and/or has a solution to fix this?

Quite weird as I don't face this! I would suggest for you to uninstall whatsapp, and then install it again. Backup its data beforehand with Titanium Backup if you intend to save the messages.

Didn't work. I still only get the messages when I open WhatsApp. Automatic hibernation is working now tho, for WhatsApp.

There's no actual fix for this, but I would try to reinstall Greenify, reset its device administrator and then clear the dalvik cache. It is quite of an isolated problem.. I sometime do have to admit Clash of Clans, Facebook and some 2 other I don't remember, stay without automatic hibernation but I can now cope with it. Thanks to swipe gestures of Nova Launcher lol.
And since it is a problem only related to certain apps, I don't think greenify should be blamed for this.

Funny thing is...if you un-greenify them and then choose to greenify them again and then hibernated them. The next time those apps will auto hibernated.
But upon reboot, the whole process starts all over again...weird.

I did a Factory Reset yesterday, because I had some issues. Thought it would work after the reset, but it didn't. How do you use the gestures to hibernate, coz I have also Nova Launcher?

You'll need to purchase Nova Prime in order for the feature to work. Assuming you have Nova and its premium features, go to Nova settings, and then tap on "Gestures and Buttons". Afterwards, choose your desired gesture, and then when choosing the action for a gesture, tap on "Shortcuts" tab, and choose Greenify's "Hibernate now" shortcut.
I personally choose the swipe up gesture. So when I am at the home screen, and I do also want my apps to be greenified forcibly, I will just have to swipe the screen up, and then the magic happens

In my case, this only happens to some apps. Others are perfectly hibernated. I agree it does feel weird, but I don't really concern about it.
Yes it only happen on some apps for me too..but if you un-greenify one of them and greenify it again and hibernated all of them, the next time all the apps will behave.

You're right, I just tested this and it actually work. Only tested this with WhatsApp tho. Thanks! But the problem I'm still having is, whenever WhatsApp is hibernated, I'm not getting any notifications and messages, even tho I have GCM enabled. I read that other people do receive them, so I find this really weird why it's not working.

I'm using Hibernate + Lock for double tap atm, and it's hibernating WhatsApp with the method above. I tested it with Google Play Services as well, but that didn't work. So my only problem now is not receiving anything while hibernated. Still can't figure this out. -_-'

You should not mess with Play Services! You should know that GCM apps use play services to deliver push notifications!
About whatsapp, most people sorted the problem out by enabling Device Admin. In the OP, you've mentioned that you did that. I suggest degreenify play services, and re-activate device admin.

Funny thing is, after I ungreenify WhatsApp and then greenify it, it will be hibernated and then I do receive the messages. Whenever I open WhatsAspp, it's going back to the 'Not automatically hibernating' list. Really werid. It says 'Service in use by Android-system Push'. The only way of hibernating it, would be forcibly, but then again, I wont receive anything and it will go back to the same list.
I removed Google Play Services from the list and did re-activated greenify in device admin, didnt work.
I had try greenifying Whatsapp before, sometimes it works real good, sometimes I encounter the same issue as you. As such, I did not greenify it again.
I don't greenify Play Services.

Ok, I think I found the solution. I had this app, called Wakelock Terminator. Within the app, I checked 'Prevent Wakelock' for Google Play Services. I unchecked it and deleted everything in the 'Filter' field and after that I deleted the app as well, because the reason I had this app was for Google Play Services.
Now WhatsApp is working while hibernated. I'm getting the notifications and messages. Maybe this would be your problem as well?

Nah WhatsApp is not the problem. It is okay for me. The only problem I have is the other apps that people don't report it here. But I don't really mind about it. And I don't kill any wakelock or some sort, so the problem lies on those rogue apps instead. Anyway glad you finally worked it out. Told ya it doesn't have to do with Greenify

Well I actually hibernate whatsapp but still have push messages come in. I have to agree it does comes a bit late but sometimes it appears instantly when I connect to a wifi. I may consider ungreenifying it though, but not now.
I want to use greenify to "freeze" a certain apps when are not in foreground, do don't check in the background for location, connect to internet to update, and so on and so forth. Like if weren't installed from the beginning. I couldn't find anything in the user interface, the app looks more oriented to hibernate the entire phone (which I don't want).

Ok look like there was a misunderstanding. Didn't mean "freeze" in the way Titanium Backup does, but rather prevent the app from doing anything unless in foreground. Greenify is capable of that, you just add the desired apps to the list.
Hibernation Manager is similar and has high ratings. Also explains things better.

My understanding is, when you add apps to the autohibernate list and when you continue to work with one app in the foreground, any other hibernated app will continue to run (if started while you are working or if already running) till the screen is locked. Only after that the running apps will hibernate. This is the behaviour I am seeing.
Correct me if I am wrong.
Edit: Even Hibernation Manager works only when screen is off. Please read its description in Play Store.

Yes Hibernation Manager and Greenify only work when screen is off. That's enough for me, but do you know if any app that does it also when the screen is on? (App always hibernating unless on foreground)
Hi,
for my basic understanding of Greenify I would like to know:
I ran Greenify 2.7 in root mode, currently without Xposed. This because I want to read more about Xposed first before installing.
It normally should hibernate the configured Apps automatically if I understand right.
In what time intervalls does Greenify check if such a App has been woken up and therefore hibernated again?
I watch the battery comsumption with 3C Tools and see, that the saving effect takes place only if I check manually every hour or so. Doing so, Greenify hibernates woken up Apps well and the battery saving effect is really good. But during the night I can see that the hibernation does not take place and I have 20% less capacity.
Sorry, if this question has already been discussued elsewhere. I have seearched here already, but being not sure, to find the right answers.
Edit: Now I Installed Version 2.8 Beta 8 and watch the behaviour.

Have you enabled Greenify in Device>Settings>Security>Device Administrator?
Do you have the donation pack?
Which version of android and what phone?
Normally, Greenify watches for apps waking up and hibernates them. There is no fixed interval for checking.
From your description I would guess that only manual hibernation is working and not automatic hibernation.
Thank you for your answer!

Ok. I could imagine, that a timer controlled action like I do it, would help.
When Greenify is not in "root" mode, it does an automated "Stop" of the Apps. With root mode it reports, that the found Apps are hibernated. When Greenify does this only once and another App will be waked up later, this now again running App will drain the battery anyway. That's not particular senseful I find. Therefore my question about regular checks.

I think so as well. But the Settings tell me that automatic hibernation is active (in German)!
The last 2 hours suddenly a process has been started named SUPL20Services. It will be reported by the 3C Toolbox analyser. This process caught my eyes several times already. The only context I found googling has to to with GPS. But when I disable GPS, this process comes up anyway. I tried to identify the parent process of it with "ps -t", but to no avail. There is no.
In this case Greenify can do nothing I believe.

When an app is hibernated, it can not wake up again unless you specifically open it or another app/process wakes it up. So a hibernated app continuing to run does not happen unless you permit it.
If you find that a hibernated app is woken up again (not specifically by you), long press the app's name in Greenify and you will get a scissors icon on top. Clicking that icon will pop up a dialogue box which will tell you what woke up that app and if you don't want it to be woken up, click the appropriate button in the dialogue box.

I think I tried this in the past and Google Services has been reported what has woken up, in this case, Hangouts. Hangouts is very "aggessive" I found and will very often be active again.
I'll have a look at the scissors next time a app will be active.

A word of caution: some apps require such wakeups to function properly. So if after using the scissors, you find that the app is not functioning correctly, you can again long press it and then click the three dot menu at top right in Greenify. You will get an option to reattach whatever you had cut earlier.

Hi All
I'm trying to get my head around what Huawei have done with the "Launch" functionality. My naive understanding is that it's huawei's own attempt at greenify. Killing apps that are not being used... somewhat intelligently.
I'm wondering if this actually has any impact on battery at all, it certainly stops processes from launching and running.. notifications being missed etc.
Anyone have any ideas what this is actually doing, or if the setting is actually beneficial? I thought google was against this sort of practice when doze is their solution.
Secondly, the following apps are allowed to ignore battery optimisation out of the box:
Backup
Camera
com.huawei.hiviewtunnel
Email
Google Play Services
Google Services Framework
Health
HwLBSService
Screen recording
System update
Any one know if it is advisable to set these to don't allow ignoring of battery optimisations?
Thanks

I am trying to understand why apps restart instead of resuming from where they hibernated. I thought the point of Greenify was to not kill the app but to hibernate it and resume it later from the same point.
A simple case of reproduction of this is: start playing a puzzle in andoku, hibernate it in greenify and move back to it. It goes back to the main screen and not show the screen of that specific puzzle that I was solving before gibernate.
Is greenify even working?

Yes, Greenify is working on many (tens of) thousands of devices. Likely YOUR device, rom or kernel is aggressively clearing memory due to limited resources. What are you using?

Not going to engage on this level. Greenify stands on its own merrits.
If not happy with the results nor willing to share device/rom/config info that might help with 'problem' determination then it probably ain't the right tool.

Are you able to resume any app from EXACTLY the same spot as you hibernated it from, after you manually hibernate it?
Aggressive OS/ROM does not matter. We are talking about a single app, hibernate manually, try to resume right away. The example of andoku I gave is a small app which does not require a whole lot of memory. So, I should be able to resume it right after hibernating it.

Just for interest, I'd downloaded and installed Andoku. Greenified Andoku. Played a few minutes and stopped within the game. Closed Andoku. Ensured Andoku was hibernated. Opened Andoku and was able to resume my game exactly at the point where I'd closed Andoku.
Just for completeness although most likely unimportant in this matter: Andoku had no internet access granted in AFWall+.
Personal conclusion: Greenify (currently on v4.6.3) works exactly and perfectly as advertised!
Personal remark: I concur with @Davey126. Unless you provide sufficient information about device, ROM, kernel and "configuration" (e.g. Magisk, Xposed, XprivacyLua, tools that restrict permissions, services, broadcast receiver etc.) most likely nobody is able to support you.

Android hibernation is not the same as Windows hibernation. Resumability is not assured - especially on a resource constrained or highly 'tuned' ROM. You should probably read up on how it works and the primary objective of Greenify which is to suspend unwanted background activity. In that respect it shares many characteristics with doze.

Did you use the pause/resume feature of the Andoku game or did you just click the game to start it again, and it resumed where you left off? Typically, if you resume using the game's feature, you have to click through 3 times to resume your game. If the app is resuming from where it left off, its 1 click just to start the game.
If you resumed the app as if you switched to it using app switcher, then something definitely is broken on my end.

I think this is where likely the disconnect is. I started using greenify several years ago (I have been here on these forums for a while, I keep that dated forum reference in my signature for remembering how far android and this community has come). If I recall correctly, I used to be able to resume apps, just by clicking or switching to them. Now, I notice a different behaviour: the app restarts from scratch. That's all. Obviously, I preferred the app to not start but resume like I was just switching to it.
I don't know if this is relevant in this case, but doesn't Greenify in non-root mode just force stop apps? I believe this to be the case because I can see it happening; i.e., when hibernation is triggered, for each app hibernated the app info screen briefly appears and the warning dialog about force stopping an app flashes on screen momentarily.

Correct. The equivalent happens on rooted devices just in a more efficient and largely transparent manner. If the ROM later opts to recover some/all of the resources consumed by the 'hibernated' app standard Android memory mgmt rules apply. In most cases that means only critical pointers are retained which may or may not contain sufficient information to resume from the point the app was in when last in the foreground.

But AIUI, force stopping an app is essentially killing the app process. So for the app to start afresh when next launched, rather than resuming from where it was left, would be expected behaviour.
Is Greenifying an app functionally better than disabling Background Activity from the app's Battery Usage page (a new setting in Oreo)? IWHT the latter achieves the same result but without killing the app.
I am running root mode. So, let's not talk about non-root mode.
If a hibernated app is going to restart from scratch instead of resume, I might as well just clear all apps (that I fed to Greenify) on screen off with 5 min delay using tasker/automate. Why bother with anything else?
The point of Greenify was to be able to resume the app after hibernate as if you just switched to it. This used to work, I have tested it in the past. Not anymore though.

Well, no ... but this is not the place for that discussion. Not going to get into Android 101 or validating speculation around various actions.

Sorry it is not working with your device/kernel/ROM/root solution. Could be an adverse interaction with the doze mechanisms in Android 9, aggressive memory management settings (eg: VM, LMK), resource mapping of the app(s) you are trying to hibernate, etc. I have not see a lot of feedback from Pie users as doze generally addresses rogue background activity and corresponding power drain. So the behavior may be different on that platform. I use Greenify on a variety of devices for other reasons for which it continues to work well. Just another tool in shop; appropriate selection is the key to success. Good luck.
