Android :: How To Measure Elapsed Time Without Current Time Milli's?

Jul 12, 2009

I want to develop a game, so I need to know elapsed time at lots places in my game. For example, to measuring FPS. I see there is some example use "System.currentTimeMillis" to measure elapsed time. But I see the warning on document: http://developer.android.com/intl/zh-TW/reference/java/lang/System.ht... "This method shouldn't be used for measuring timeouts or other elapsed time measurements, as changing the system time can affect the results." So, if this method should not be used for measuring elapsed time, then what will be suitable?

Android :: Time Elapsed Since AC Supply Unplugged

Aug 17, 2010

I'd like to know if there is a way to get the elapsed time since the phone was unplugged from AC supply. I know that I can register a receiver to catch battery events - but this just works if my service is running already when the status changes. In my case I assume that the application is started when the AC supply was already plugged out before and I then want to retrieve the time.

Android : Need To Calculate Time Elapsed - While Developing Game

Jun 4, 2010

So I've been struggling with this and I am not sure why because it should be simple, but for some reason I just can not get my head around it !!

I am developing a game and when the user saves their game, I write out the last time I checked their stats using System.currentTimeMillis(). Then when they load in the game I want to see how many total seconds have elapsed since it was last saved. Naturally I thought of getting System.currentTimeMillis() and then deducting my saved value and then converting that into seconds using this :=

long timePassed = System.currentTimeMillis() - lastCheck; int seconds = (int) ((timePassed / 1000) % 60);

But on each load the seconds keep altering, but not within the right bounds. For example on one load it comes as 59 seconds, then it showed 23 seconds etc. Obviously my algorithm is slightly wonky but I can't work out why.

Could some one please elaborate where I am going?

pseudo code

{
//do this
}
else if (curTime>7pm AND currTime <10pm)

[Code]...

General :: Determine Current Time Is Between Two Other Time Objects?

Dec 28, 2012

How can I determine if the current time is between two other time objects?

For example: current: 15:23, startTime: 22:00, endTime: 06:00. So the current time is not between this two other times, but this "23:47" is.

*I don't care about the date, only the time

I tried to do it like this:

Code:

Time startTime = getStartTime();
Time endTime = getEndTime();
Calendar c = Calendar.getInstance();
Time now = new Time(c.getTimeInMillis());

[Code]...

but it dosen't work well. their aren't any errors but it just dosen't work.

To be more precise the problem is that 15:35.after(22:00) return true... and I don't know why. I think that the problem is something with the dates but I don't know what

How To Measure Little Time Intervals

Sep 17, 2012

I would like to make an app that measures little time intervals (nanoseconds) so I need to know about time resolution and precision regarding such measures with an Android device.

In other words:

- Is it feasible to get reliable values of the current time with nanosecond resolution?
- If so, is feasible to measure such little time interavals? I mean, is there any way to tell the app/OS to focus on measuring the time interval specified in the current thread instead of allowing other processes to make the measuring task not precise?

I've tried to measure the time between the execution of two different lines in code but the results are not always the same, somehow random, then I suppose Dalvik and its process management is causing this to be unreliable and random. What I need to do is to measure distances by getting transmission and reception of audio tones of 16-20 KHz (done in [1] with iOS), thus needing resolution and precision.

Android :: How To Get Current Pure UTC Time?

Aug 25, 2010

I need to get pure UTC time in application level. It should not be changed by user or location or anything else. When I try with System.currentTimeMillis() or getTime() of Date class, they always return value of local time. If user change date or time, the return value is also changed. I found handleEndOfInit method in android_modem.c (externalqemu elephony) and the method is like below. Probably, the variable "utc" is what I want.

1. Is the android_modem.c for emulator?? 2. If it is, I think there must be similar file for target. Where is it? 3. How can I get the "utc" value in my application?................

Android :: Converting System - CurrentTimeMillis() Into The Current - Readable Time

Nov 15, 2010

is there a way to use the System.currentTimeMillis(); to have convery that number into a basic output HH:MM in droid? I am using the sample code:

Toast.makeText(this,
String.valueOf(System.currentTimeMillis()),
Toast.LENGTH_LONG).show();

That outputs the current time in MS since the epoch. There has got to be a better way to do this rather than convert that large number and display the current time right?

Android :: GetFromLocationName Always Throws IOException First Time - But Is Successful Second Time With Same Input

May 29, 2009

My calls to getFromLocationName() always fail the "first" time I start my app. I catch the IOException which has reason:

Unable to parse response from server

Then I make a second call and it succeeds. Once things are "awake" all future calls to getFromLocationName() succeed, it's just that first one, and there is a ton of latency.

I haven't run this on a device yet, just in the emulator. This seems like a network problem, but it is so reproducible I'm thinking I'm not initializing something properly. I'm using Android SDK 1.1.
