Applications that close by themselves - OnePlus 6T Questions & Answers

How to prevent apps from closing on their own?
For example, I have an application (A) that allows to open certain applications (B, C, ...) by a code or footprint. The problem is that as the application (A) is closed by itself after a while, I no longer have protection.
I tried in the settings to ask that the Application (A) is not optimized for the battery, but it's the same.
Looking forward to your help

Just WHY don't most programs have an "Exit" functi

... that ends them permanently rather than have them run on in the background?
Any rational explanation for that at all?
There is. You should read the MS design guides as to why, but basically, it's faster. And programs programmed "correctly" should be administered by the system, the system will close them down when they're no longer necessary and/or a drain on resources required by other programs. Otherwise, why close them?
However, many argue that that decision should be made by the user, not the OS. There are enough 3rd party solutions to fix the "issue", that it's hardly an issue any more IMHO.
V
Basically the choice comes from the assert "The user use his PDA not the applications in it."
Besides anybody's point of view, however, most applications following the microsoft desing guideline CAN be closed the way you mean by pressing ctrl+q in the keyboard (whatever keyboard you use, soft or hardware). This option, introduced for debuggin purposes, is always left even to release versions of correct developed programs.
Just try it.
I use magicbutton to get a proper 'close' button. It works, but as the other have mentionned, if you use the same 3 or 4 apps over and over again during the day, having to open/close them everytime is actually slower than having them loaded all the time.

Apps that runs on startup/background

I hate it when an app runs in the startup specially if the app is not that important. Is there any way of disabling those apps that run in the startup? As well as those apps that runs in the background even if you don't need em to? They eat up RAM and make the NC slow! I wish I can manage them.
Let them be android takes care of itself.

Yes...get an app in the market called Android Optimizer, it is free. In the menu hit the startup manager icon. Disable the app (s) you don't want to run at start up or background.

You do not need an app like this. People use task killers and startup blockers and then complain about how crappy and slow stuff is because THEY ARE NOT ACTUALLY RUNNING IN THE BACKGROUND. They are cached for faster start up next time. They do not take up any battery or CPU power. Android is linex not windows.
--------------------------------------------------
Here is the post i linked to earlier:
I develop Android apps so I though I'd explain why a task killer isn't needed on an Android system.
Activities
Android apps use activites to preform tasks. For example, if you use a file manager to send a picture via email, the file manager calls the send activity within an email app, passes the file name to it and the email app sends the picture.. not the file manager. This will result in seeing the email app as "running" even though the user didn't actually launch that email app.
Smaller apps
Using activites helps developers design smaller apps. A file manager app that contains every bit of code needed to do everything a file manager does would likely be so large that no one would want to install it. Developers know that an android phone more than likely has an email app so there is no need for the developer to include email code in his/her file manager to send a picture when he/she can call an activity in an existing email app to do the job. This results in a smaller file manager app since there is no need to include email code or any other code for an activity that can be done via an app that is already present on the phone. This also alleviates redundant code. When you install an app outside of the android market, also known as sideloading, the file manager app calls the package installer (already present in Android) to install the requested app.
Running apps vs. cached apps
The "Manage Applications" list included in many android devices lists running apps as well as cached apps. Cached apps don't use any CPU or battery, they're cached so they will load faster the next time you need them. Killing cached apps results in those apps requiring more time to load the next time they are launched.
System management
By default, every android application runs in its own Linux process. Android starts the process when any of the application’s code (activities) needs to be executed, and shuts down the process when it’s no longer needed and system resources are required by other applications.
* Android is hard coded to automatically kill a task when more memory is needed.
* Android is hard coded to automatically kill a task when it’s done doing what it needs to do.
* Android is hard coded to automatically kill a task when you haven’t returned to it in a long time.
* Most services (while possibly running in the background) use very little memory when not actively doing something.
* A content provider is only doing something when there is a notification for it to give. Otherwise it uses very little memory.
* Killing a process when it isn’t ready only causes it to have to reload itself and start from scratch when it’s needed again.
* Because a task is likely running in the background for a reason, killing it will only cause it to re-spawn as soon as the activity that was using it looks for it again. And it will just have to start over again.
* Killing certain processes can have undesirable side effects. Not receiving text messages, alarms not going off, and force closes just to name a few.
* The only true way to prevent something from running at all on your phone would be to uninstall the .apk.
* Most applications will exit themselves if you get out of it by hitting “back” until it closes rather than hitting the “home” button. But even with hitting home, Android will eventually kill it once it’s been in the background for a while.
If you see an app running that you didn't launch, it's most likely because an activity within that app was called by another app to perform a task. If you kill the app you didn't launch, the system has to relaunch that app in order to complete its task. This is why some people kill a task and then see it immediately running again. Constantly killing that app creates a situation where the user is battling the system resulting in wasted system resources.
Android is Linux
Android is not a Windows-based OS, it is based on Linux. Many of the apps you think are running aren't actually running, they're cached, this is typical with a Linux operating system and is much more efficient than other systems. Cached apps don't use any CPU or battery, they're cached and will load faster the next time they're needed.

Yes..I have noticed some side effects.alarms and what not. I guess ur right the only real way is to completely uninstall the apk ..would u happen to know why my adw launcher keeps forceclosing each time boot my nook? I am not running any icon packages..so what other source (or app) could be calling on it to run at startup?

I am not familiar with adw. Is there an option to save it in memory I know that many replacement launchers do so you might want to make sure that is checked.
Also if you are using a task killer, it is probably trying to kill it and that could cause it to force close.

Do you have Titanium Backup installed? You can clear data and uninstall apps with that as well.
auto starts kills those apps... i run it on my NC>.......i dont need dialer /voicemail...etc.....
Just a thought but if you continue to have force close issues with apps, try running fix permissions. This usually ends the issues. I run adw ex and have no problems. Those few times I have had issues, fix permissions has solved the problem. Just sayin.....

Why some apps are only like a service?

Hi, why some default apps run only like a service? Gmail app and gtalk app runs only like a service...
And are some apps appear in Active Apps panel ans not appear in In Progress panel... Is very confusing... I'm not understand what app are running and consuming battery and memory...
Someone can help ?
If the cpu usage for app is 0%, it doesn't consume battery. And freeing memory doesn't help with battery drain, it's quite opposite. Try to find some threads here in "General" section with keywords: ram, multitasking, lmk, minfree...
Ps. Android isn't windows, so things work quite differently..

There is a difference between a service and a process.
A service is a component that runs in the background to perform long-running operations or to perform work for remote processes. A service does not provide a user interface. For example, a service might play music in the background while the user is in a different application, or it might fetch data over the network without blocking user interaction with an activity.

When an application component starts and the application does not have any other components running, the Android system starts a new Linux process for the application with a single thread of execution. By default, all components of the same application run in the same process and thread (called the "main" thread).... Every application runs in its own process and all components of the application run in that process, by default

The Android system tries to maintain an application process for as long as possible, but eventually needs to remove old processes to reclaim memory for new or more important processes. To determine which processes to keep and which to kill, the system places each process into an "importance hierarchy" based on the components running in the process and the state of those components. Processes with the lowest importance are eliminated first, then those with the next lowest importance, and so on, as necessary to recover system resources.

In a few words... Gmail and Talk are only services that are constantly monitoring incoming push data from the Google servers. There is also a WhatsApp, Google+, Music, Email, and many other services that are automatically started when an event triggers them. This depends on the app. Not all apps have services. For instance, a Live Wallpaper is a service, not a process. You should not kill those.
When you run an application, you start a process. This process holds all the UI and logic to display the application in your screen. If you press HOME on your phone, the process goes to inactive mode, and it "in theory" should stop using CPU cycles and will sleep in your RAM until you execute the app again, or until Android claims the RAM and kills the app. RAM does not kill your battery, CPU cycles do.

Why should not I kill them? I installed Germini App and stop GTalk and others to automatically init on boot.

Develop an app to block launch of other apps

This is some hobby project i want to accomplish with, i have decent experience in programming java. But after quite a lot searching around and asking professors and anyone with experience in android development i got no clear vision of how this is accomplishable. The thing is, i want to develop an application that runs for a given amount of time(there´s a timer the user sets), during this given time certain applications will be blocked(or rather killed, or intents changed so they won´t even start to run). This selection will be done from a list given of third party applications installed.
As mentioned, ive searched everywhere i can, and the only leads i could ever find was the following:
1. Have continous check which kills the given application if it detects the specific applications running and will kill it. Downfall of this will be cpu-usage, optimalization and battery use. And also the device has to be rooted.
2. Have an alternative launcher, somehow this should help me a bit on the way to accomplish my goal. But here i sit thinking: Will i need to develop my own launcher to be able to succeed?
Nothing pointed me in any direction whether there are some native methods or similar in the android that perform similar tasks and how to implement it at all. Those who are saying there are plenty of applications our there similarly: No, they give you choices like block apps with a password and similar which is not what i´m after. I need some application that blocks it for the given time it´s set to(even though it is possible to go on your own in task manager and kill this application i want to develop, but that is out of the scope for now). This is to increase productivity without reaching for your cellphone all the time(yes, it might sound silly, but i´m quite sure it will help.
Any help is greatly appreciated as i´ve researched for over a month without any success.
Bring up your activity no matter which app starts. Make it a transparent activity and kill it as soon as it starts.

[DEV][LIBRARY] KillerWhale - Escape vendor battery optimizations (testers needed)

Many device manufacturers include a so-called feature in the Android OS, that optimizes or kills the background processes, alarms, broadcastreceivers of almost all third-party apps. (The few exceptions are some popular apps, such as Facebook, Instagram, etc.)
So I have started a project which aims at helping developers adding their apps to the whitelist of such optimizers, since in some cases it is necessary for our apps to work properly. Of course, there is no API provided by the manufacturers, the only thing we can to, is to instruct the users what to do, and start the intent that leads to the whilelist.
KillerWhale (as these applications kill other apps) can be found at:
https://github.com/hexadec/KillerWhale
Anyone who could test if these intents actually work (I dont have phone from most brands listed there) is welcomed, as well as those who have anything to add here!
This project has a .csv file containing known package names and activity packages needed to start the activity, with vendor names on which they should work, and an API level range. OrcaManager.class checks whether the current device is in the list, and starts all intents matching it. orca.csv needs to be put in the assets folder of the application including it.
Bear in mind that not all of these Optimizers work the same way. Samsung and Huawei, for example kill the apps in the background after a certain amount of time, whereas Sony's Stamina mode works similarly to Doze.[/SIZE]
