If you switch from on task to another does the preceding task or app stay open in the background and consume RAM, or does it not?

android will usually kill the apps but some of them stay on and run in the background if you really want to check go to manage apps on android and click running apps

They still consume the RAM since it still running in the background. You need to close them to free up the RAM again.

Obviously Yes if it runs in background like facebook etc
2012-10-27 14:37:23
yes it consumes some of the ram and if you want to se its ram consumption turn on task manager on your homescreen .and if you want that if you walk out off an app after that it should stop running then go1 ] into settings 2] developer options3] look into section of apps4] and select strict action mode

of course they do. To solve this go to task manager on your android and clear ram

Yes, but this isn't a bad thing. If the app is stored in RAM, it will be faster to switch back to it.Bear in mind that there's no point in having empty RAM. Empty RAM is completely wasted. When Android needs RAM, it will remove apps from memory to get RAM back.This is why task killers are a bad idea, except when apps are poorly coded and misbehaving by using CPU and other resources in the background. I mentioned this in the bottom of this post: http://www.makeuseof.com/tag/android-faster-works/

Great answer Chris!This is from personal experience, there also seems to be a direct correlation between apps that constantly run in the background and the overall sluggishness of your handset. I'd bet that 90% of the apps that cause such slow down are merely poorly coded, but there are so many poorly created apps in Android that the problem is a common one.Also, if you use a battery usage analysis tool, like BetterBatteryStats, you'll notice a significant increase in battery drain the more apps you have running in the background. BBS is a great way to determine which apps are causing wakelocks. Or in other words, which apps are forcing the phone to wake up from deep sleep.Aside from deep sleep issues, I believe the primary cause of handset slowness is largely related to the resources that paged out apps draw upon - primarily GPS, WiFi and 3G/data. These oftentimes have a tremendously negative impact on battery life. So while the official line from Google is that running apps in the background isn't harmful to system performance, in reality, given the sheer volume of poorly designed apps out there, it's not very good. :-(

yes
2012-10-21 08:38:23
yes the preceding app stays open and consumes RAM until you close the app.You can check which apps are open on the task manager and even close it.
2012-10-20 20:52:52
yes, but you can shut down the apps if you are running you of memory
2012-10-20 17:24:02
It takes your memory but as soon as you use more apps and don't use earlier opened app, the older one will be removed from memory.
2012-10-20 16:14:52
Yes is the right answer. Download and run an app called Advanced Task Killer and you will see which apps remain open and consume RAM.
2012-10-20 13:27:56
Yes until it is shutdown by either the android system or by a 3rd party task manager.
2012-10-20 12:44:30
of course they do close them to gain RAM
2012-10-20 11:16:15
Try to close an apps that you won't think you will be using again to decrease RAM consumption to the minimum. If you do this you will keep your phone running smoother. Also, a reboot at the end of each day will also help your phone run smoother.
2012-10-20 08:38:42
if you have task manager and look into the ram you can see some applications running in the backcround after closing them. so you have to kill them and to gain ram. Note that minimum services are required to be running in the background for the android os to work properly.
2012-10-20 08:17:51
They do for sure.. Some even use memory if you haven't opened them even. The facebook app is one of the worst offenders. It ran an avg. of 56 megs in the background constantly. Try out Zdbox and use the task killer :).
2012-10-20 07:30:04
yes. it can consume memory for a little time and if the android os realize that the program in the background is not any more needed, it will cache the process. unless it has services that run along. Then the application will run in the background and consume memory. I recommend you to close any unwanted background application unless they a absolutely needed. don't use the home button long press to switch application. if say, you are browsing FB with chrome, and you want to switch to PowerAMP to select a track, do it. but don't use that every time. u'll pretty soon realize that the responsiveness is crap when you do it!
