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?

The call to System.currentTimeMillis() returns always 0 on Motorola Droid, Android 2.0.
There is no mentioning in changes to System in the API differences between 2.0 and 1.5, so either it was missed somehow or this is a Droid dependency.Does anyone know how to get the currentTimeMillis in a way that satisfies Android 1.5, Android 2.0, and all hardware? Best regards!

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

I am testing my multiplayer game by running several instances of the emulator (which is, sadly, extremely slow and dis-satisfying). I depend on a little trick using currentTimeMillis() to keep a synchronized clock between the players (but NOT the absolute value of currentTimeMillis() since no two phones are probably set exactly the same)Anyway, I *do* naively assume that two emulators, running on the same PC would return near identical values for calls to currentTimeMillis(), and what I find is that they start off the same, but pull rapidly apart.Which makes me think the underlying implementation of currentTimeMillis() in the emulator is not at all based on the host PC's calendar, and rquires the emulator to get enough Windows compute cycles to be anything close to accurate. (and one emulator is always running at a lower priority to the other, depending on which one is on top)
If this is just an artifact of the emulator, then I can deal with it, but if it implies I have a fundamental misunderstanding of currentTimeMillis(), then that would be something i need to deal with. Part two of the question is: any way I can speed up the emulator? When I run two, are they sharing one of my cores? Can I split them onto separate cores?

I've read through the step-by-step here, and while I've found it to be the clearest set of instructions I've encountered, I still have a couple points of confusion. It sounds like by the time I get to the end of Section 2 (version 1) I will have a custom ROM installed (2Q). Now I've used Titanium Backup (I used the pre-OTA Unrevoked for su) to back up apps/data/settings. But I'm not sure what that gets me. What if I want to revert the phone to exactly how it is now? A Titanium Restore would restore apps/data/settings into the custom ROM loaded in 2Q correct?
It appears my answer is in Section 3, item 3D (NAND backup). But at what point do I do Section 3? If I've already gone through Section 2, my current ROM is overwritten by the custom ROM loaded in 2Q, so it's too late to back it up, right? Perhaps I'm making this more difficult than it needs to be, and I'm usually not a complete idiot about technology! But I'm having trouble getting my arms around some of these concepts. I see a lot of instructions saying "do this, do this, do this", but very little explanation what's actually happening when I do these things, and why I'm doing them, so I'm failing to grasp how the various pieces and actions are fitting together.

Is it possible to share files between two apps?
My scenario is this: I want to create a free/demo version of my game and a complete version. The player should be able to play the free version, then upgrade to the complete and continue where the free version ended - ie. the complete version would need to load a savegame created by the free version.
