memory - How to kill currently running task in android Marshmallow -

i'm trying find way how kill task in android marshmallow have 2 methods both works fine in android 4.0.3 , android 5.0.1 when trying in android 6.0.1 doesn't work idea resolve problem !,

list<applicationinfo> packages;             packagemanager pm;             pm = getpackagemanager();             //get list of installed apps.             packages = pm.getinstalledapplications(0);             activitymanager mactivitymanager = (activitymanager)getapplicationcontext().getsystemservice(context.activity_service);             string mypackage = getapplicationcontext().getpackagename();             (applicationinfo packageinfo : packages) {                 if((packageinfo.flags & applicationinfo.flag_system)==1)continue;                 if(packageinfo.packagename.equals(mypackage)) continue;                 mactivitymanager.killbackgroundprocesses(packageinfo.packagename);             } 

and method :

activitymanager = (activitymanager) getapplicationcontext().getsystemservice(context.activity_service);             (activitymanager.runningappprocessinfo pid : am.getrunningappprocesses()) {                 am.killbackgroundprocesses(pid.processname);             } 

try using in second method.

android.os.process.killprocess(pid); 

kill process given pid. note that, though api allows request kill process based on pid, kernel still impose standard restrictions on pids able kill. typically means process running caller's packages/application , additional processes created app; packages sharing common uid able kill each other's processes. taken here

i recommend getting application id using

android.os.process.mypid();
