I want to be able to show the elapsed time in a textview or Chronometer held in a "Statistics" class since pressing a button located in another class. What would be the easiest way to implement this?

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?
View 2 Replies View RelatedI'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.
View 2 Replies View RelatedI am writing a app for which i need to display the Time elapsed when user presses a button in UI screen .
So please guide me in writing the code in Android. I need to display the time in seconds, mins and hours.
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?
I use my phone as an audio player while outside with a bluetooth headset. I have the phone in my pocket. However,it seems very easy for the side buttons to be pressed, even when the phone is locked. What do you all do for this? I have tried a couple things and did find a "solution", but it's not one that I like, and would appreciate hearing thoughts from others.
View 4 Replies View RelatedI have a pattern unlock on my Samsung Galaxy S 19000. If I want to lock my screen manually I simply press the power button briefly which works fine. I now use a skin on my phone which doesn't allow for easy access to this power button so I'm wondering if there's an app that I can use to lock my phone screen without having to press the power button. I have looked at "lock 2.0", however, it seems to be more for actually unlocking the screen.
View 4 Replies View RelatedI'm new to Android and just starting the very basics. I implement my custom button skin using .9.png images for norma/focus/pressed states. It works fine, but I noticed that after a pressed the focussed button it visually "lost" focus and draws the normal state frame. I planned to use different state images to highloght what button is selected right now, but it seems that it would not work. I noticed also that the same happens with the default LAF button. Is it OK, or it's just emulator issue? What the good workaroud can be used?

View 1 Replies View RelatedWhenever I press the home button when Im in the root task of my application and when I click on the icon of my app again the state of my task (activity) is retained, but when i press the back button on the emulator and when I open my application its state is not retained. I want the state to be retained in both the scenarios.
In the mnifest I have given the below entries,
android:alwaysRetainTaskState="true" for the root activity
android:launchMode="singleTask" for the application
When i leave my app after pressing home button and then re launch it from menus it behaves in a strange way.Sometimes it launches the same activity on which i pressed home button.But sometimes it launches the first activity of my app. One reason for this could be that whenever system has memory shortage it clears any activities existing in But the strange thing is if i press back button from first activity it takes me back to the same activity on which i pressed home button and all other previous activities are also there(like if i press back button again previous activities also exist.)I haven't set any launching mode for any activity in my app(like single instance etc).What i don't need is that previous activities load on pressing back button on first activity.

(like the iPhone's home button, just converted ) I've looked around and can't seem to find a way to set this.

One thing I found annoying was having to press the power/unlock button and then swiping the screen to unlock the phone every time, is there anything in the market or some setting to avoid pressing the button and just swiping the screen or possibly using the touch buttons on the front of the phone then swiping?

Now whenever I press the home button, it brings up CM10's home screen.
How do I bind ADW to the home button?
Is there any way to make it so when i press and hold the power button and choose either silent or vibrant only that it will also mute media? I am hoping for the ability to change something through adb shell or something because I use the power button method all the time I just really want it to mute/unmute the media volume too.
View 3 Replies View RelatedWhen I'm talking, my hair tends to press the mute button on the home screen and the other person cannot hear me. I've searched but can't find a way to make this stop. An app, a better phone-holding technique--I'll try just about anything. Also, for some reason I had a glitch the other day... I made a phone call, got my friend's voicemail, and then was unable to hang up the call. I ended up leaving a rather long, embarrassing voicemail message until I just went in and force stopped the dialer app, but at least my friend has a good sense of humor.

I find the power button to be annoying and wish both would "wake-up" the screen.
i focus my eyes on /sys/class/leds/button-backlight/, however, i can just turn off the backlight.
i found that the trigger in it can do complex work, so i tested it, and found some codes below
Code:
[none] rfkill0 mmc0 mmc1 mmc2 timer heartbeat sleep rfkill1 rfkill2 max8903a-usb-online max8903a-ac-online battery-charging-or-full battery-charging battery-full battery-charging-blink-full-solid
however, i haven't found the one i want.
Anyways, whenever i'm listening to music, and I press the play/pause button on my headset to control my music tracks, my phone turns on. This get's really annoying because every time my phone turns on, it stays on for a few seconds, and this really kills battery life. I've tried lurking around my phone's settings and even my launcher settings.

View 1 Replies View RelatedReceived my 2.1 OTA at 1:36 AM last night and ever since, I can't manually lock my phone by short pressing the power button anymore. I thought maybe this was a Spare Parts issue, since I had changed the Power Button behavior on 1.5 using Spare Parts (when I pressed Power from any screen, it would return me Home; pressing from Home would Lock). So, I uninstalled Spare Parts, but this didn't remedy my problem. Any advice?

My question is about restoring complex activity related data when coming back to the activity using the "back" button". Activity A has a ListView which is connected to Array Adapter serving as its data source - this happens in on Create(). By default, if I move to activity B and press "back" to get back to activity A, does my list stay intact with all the data or do I just get visual "copy" of the screen but the data is lost? What can I do when more than activities are involved? Let's say activity A starts activity B which starts activity C and then I press "back" twice to get to A. How do I ensure the integrity of the A's data when it gets back to the foreground? Prefs Manager does not seem to handle complex object very intuitively.
