android: how to get memory usage (ram) of a given PID programically -

-

i want log ram usage of given application @ given time rate. wrote code full memory value used not know how memory usage of given pid.

please me out

this code used memory

 activitymanager localactivitymanager = (activitymanager)getsystemservice("activity");     activitymanager.memoryinfo localmemoryinfo = new activitymanager.memoryinfo();     localactivitymanager.getmemoryinfo(localmemoryinfo);     log.i("",string.valueof(localmemoryinfo.availmem));

i think can using public memoryinfo[] getprocessmemoryinfo (int[] pids), not know how code since im android beginer

activitymanager localactivitymanager = (activitymanager)getsystemservice(context.activity_service); // use context.activity_service not literal "activity" list<activitymanager.runningappprocessinfo> procsinfo = localactivitymanager.getrunningappprocesses();  int[] pids = new int[procsinfo.size()]; (int = 0; < procsinfo.size(); i++) {     activitymanager.runningappprocessinfo info = procsinfo.get(i);     pids[i] = info.pid; }  debug.memoryinfo[] procsmeminfo = localactivitymanager.getprocessmemoryinfo(pids); // walk procsmeminfo array

if schedule recurring timer periodically re-query running pids , query memory info can use timestamps compute memory usage on time.

i wish write custom appender on basis of outputstreamappender . wrote following class package tests; import java.io.ioexception; import java.io.outputstream; import ch.qos.logback.core.outputstreamappender; public class myappender<e> extends outputstreamappender<e> { public myappender() { system.out.println("myappender created"); setoutputstream(new outputstream() { @override public void write(int b) throws ioexception { throw new unsupportedoperationexception(); } }); } } then wrote following runner: package tests; import org.slf4j.loggerfactory; import ch.qos.logback.classic.logger; public class runner { private static final logger log = (logger) loggerfactory.getlogger(runner.class); public static void main(string[] args) { //log.addappender(new myappender<iloggingevent>()); log.info("hello world"); } } finall...

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
