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 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.

View 3 Replies View RelatedSo 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?
In my android app, I need to design a Welcome Screen which will be shown to the user only once after the app is installed and opened. The app in question is a database driven app and I would love to include some 3 - 4 screens to help the user create re-usable resources for use within the app and a few tips. They would be Dialog Alerts with the last welcome screen showing the "Do Not Show Again" checkbox. how to show the welcome screen just once.

So here is a quick example of how I was intending to do this.
1) Create an XML which positions 2 ListViews one onto of the other each ListView having there own ID
<ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="198px"
I am getting a date/time string from web in the format of "yyyy/mm/dd'T'HH:MM:SS'Z'" and it is in UTC. Now i have to identify the current time zone of device and then convert this time to my local time. (FYI, Currently, UTC time is 10:25 AM, in india current time is 3:55 PM)

View 4 Replies View RelatedIs there any way to change when these 3 things happen separately? Can I make it so my screen fades earlier but still takes just as long to go completely black? Is there a way to extend the time between total blackout and locking? Is there a way to turn off auto screen lock all together but keep the auto fade out and auto black out? I am always able to remember to manually lock the screen and the auto lock is annoying but I still like the power saving of the screen fade and black out.
View 3 Replies View Relatedat 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?

How can I display a button on screen? I have defined it as
final Button nappi = (Button) findViewById(R.id.soita);
and
<Button

android:layout_height="wrap_content"
android:text="@+string/Soita"
android:id="@+id/soita" />
I want to create an AnalogClock that can display a preset time, given as a parameter.
And I want to draw between the background and the hands. I want to paint the area between the minute-hand and location of the hour-hand at a preset future time. This is to let the user see how much time remains for the current activity.
I thought that I could take the AnalogClock object and extend that. However, when I create a new function that is essentially a copy of one of the old ones, I get errors on the com.android.internal.R.styleable.AnalogClock* objects: "com.android.internal.R cannot be resolved"
How can I import these objects? I've read something about declare-styleable, but I cannot figure out how to apply that to my situation. (Sorry, I'm really a Java n00b)
For instance, the internal objects refer to several graphical things, such as dials, hour_hand and minute_hands.

View 1 Replies View RelatedI know I can use android.text.format.DateFormat.getDateFormat() to format my dates, and android.text.format.DateFormat.getTimeFormat to format my times, but how do I format a datetime? Similar to the getDateTimeInstance method from java.text.DateFormat. I'm currently just concatenating the result of both the getDateFormat and getTimeFormat's formatters, but I don't know which way around the user prefers to have their dates and times shown.

View 4 Replies View RelatedToday my EVO recently decided to start displaying Pacific Time and thinking it's in Spokane, Washington (I live in Oklahoma). My phone number is from Spokane, WA but I moved from there a month ago and haven't had this problem until today.
I've tried changing the current city in the clock app, updating my PRL, changing the current city in the weather app, unclicking/reclicking "use wireless networks" to determine location, and nothing works.
The GPS shows I'm in Oklahoma but the time/time zone is still showing Washington. I'm lost.
I am just looking for opinions, which phone do you think has the better screen (display), the nexus one or the Droid? I guess 2 things to consider are
1. The Droid is 480 x 854 while the nexus one is only 480 x 800 and
2. The nexus one has an AMOLED display.
Now I am not the most tech savvy person so I am not 100% sure what these mean lol all I know is that from what ive heard, #1 goes to the Droid and #2 goes to the nexus. So idk, is it really just a matter of opinion? I own a nexus one and it has a great screen but from what I've seen from the Droid, the droids screen looked a tad better. However that could be due to my limited experience and if I had the Droid for a while, my opinion might change.
Yesterday my Droid 2 got automatically updated to 2.3.20.A955. It worked fine yesterday. I turned it off when I went to bed and now this morning after turning it on, it appears to be functioning except the only screen display I get is the white M (Motorola logo) that normally appears when starting up. I have tried to turn the phone off and on several times, although with no display it's hard to even know if it's happening. So far, nothing.
Edit to add: Well, I took the battery out and put it back in, now it's working. I should have tried it earlier but I didn't. I'll leave the thread up just so people know there is an issue.
Under settings theres a setting for screen time out..I put it to 30mins and leave the phone alone...the screen goes out in like 20 seconds...I'm pretty sure that's not 30mins...is this a software or hardware issue?

View 3 Replies View RelatedSome questions regarding locked screen.
1) How do you get the locked screen to show for more than 5 seconds?
2) Where is the clock that is on the box?
3) Is there a way to be able to use the "droid" theme that is shown when you power the phone up?
The gap between the screen and housing, particularly at the bottom, seems to be pretty wide on my phone. i notice at night that light shines through that gap. Can't tell if the gap has gotten any wider. Just wondering if anyone else notices something similar. Seems like a great place for dust to enter the screen. Especially if light can come through there. Doesn't mean it's not sealed, but obviously it's not a super tight fit.
