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?

I have tried searching the database for this and googled it and I couldn't find anything.
I'm not very experienced in Android, however, I am trying to develop an application. Within the application I want to check if the current time falls between time ranges
pseudo code
[HIGH]if (currTime > 9am AND currTime < 7pm)
{
//do this
}
else if (curTime>7pm AND currTime <10pm)
[Code]...

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

I'm just trying to find the way to get current time. But I don't want to use currentTimeMillis() method, because the current time on device may be wrong. Is there any way to make some request to the Internet to get right current time?

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?................

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?

The default behavior of an activity when BACK softkey is pressed is, GO BACK TO PREVIOUS ACTIVITY. If some the same activity is waiting for some response from server or some data updation is going on and then press BACK, I want to wait on the same screen till the current task is completely processed and then move out to the previous activity.

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.

at the moment I am thinking about a new app and need some information to decide whether to develop on Android or an alternative OS. I am particularly interested in "time to first screen", "boot-up time", "time to first Audio" and "app-start" (can be any from the android market or even one of the pre-installed ones) time? Does anyone know a source or perhaps measured those numbers?

Is there any android widget that enable to pick the date and the time at the same time ? I already use the basic date picker and date picker:
http://developer.android.com/guide/tutorials/views/hello-timepicker.html
http://developer.android.com/guide/tutorials/views/hello-datepicker.html
but they are not that sexy and user friendly (I found). Do you know if a widget including both date and time exists? Thanks a lot,WW.

I am trying to get a local time from a server UTC time. I get the UTC time form the server -- and i want to make it right for each individual Android phone whether it be in California or China. This is the code I am using now -- however it snot working.The time I get from the server is "2010-08-17 19:41:13.0" And the code I use to get the difference(in seconds) is the following: public static long getSecondsDifference(Timestamp timeStamp) { final Calendar calendar = Calendar. get Instance (Locale.getDefault()); int refrenceOffset = TimeZone. get Default (). getOffset(timeStamp.getTime()); final long referenceSeconds = (timeStamp. get Time() + refrenceOffset) / 1000; final long currentTimeSeconds = (calendar. getTimeIn Millis()) / 1000; final long differenceMinutes = (currentTimeSeconds - referenceSeconds) / 60; return differenceMinutes; The timestamp is from the java.sql.timestamp package.Right now the time where I am is 11:50AM -- and the method returns that the given server time is -53 minutes ago( so obviously doing something wrong
