I found that first of all System>Apps>Running is not helpful always and secondly I we stop the services, it may star again if corresponding application is running. The correct way to stop application is force stop. (that's why ram booster may not helpful sufficiently).
I've made an simple script that get the list of all user applications and then force-stop all one by one:
pm list packages -3 -f | sed /jackpal.androidterm/d > /sdcard/tbs/app2fs while read -r line; do APK=$(echo $line | cut -d ':' -f2 | cut -d '=' -f1); PKG=$(echo $line | cut -d '=' -f2); echo "Forcing to Stop: $(aapt d badging $APK | grep "application: label" | cut -d "'" -f2)"; am force-stop $PKG; done < /sdcard/tbs/app2fs
The draw back of above command is it tries to force-stops all (doesn't matter running or not) third-party applications. But I want to do
am force-stop only for the running user apps.
So, How do I get the list of all running user apps (not services)?
You may have better way to do this than my script/command, hence broadly: How can I force-stop all user applications that are running?
Note: I recommend the command-line solution. Because this type application (that can force-stop all running user apps) mostly runs constantly for monitoring which I don't like. If you've a suggestion for an app that can do such job and also favourable (should not run constantly for monitory) , then you can suggest it.
