Android :: Difference In Traceview Time
Sep 24, 2010
I'm usign starMethodTrace() and stopmethodTtrace() to get trace data to use on traceview. Everything seems to work fine. I test my app for 50 (real world) seconds having two important events after 15 and 45 seconds from start tracing. However, when analyzing the traceview's timeline I found the total tracetime is only 1.068,964 (msec). My two events are displayed as they were occurred at time 257,743 msec and 642,654 msec. This is just about 1 second of total execution time. Why there is this huge difference between real world time and trace view time? May be because I have a lot of idle time? Is there a way to relate the times displayed in the time line with real world time?

I want to make calendar view in order to support touch interaction. So I'd like to build new custom calendar view. I tried to make mapping function between view offset and real date value.
Here is my idea:
If I can compute the number of weeks since base date(in my case, 1989-12-31), it is easy to know offset. HEIGHT_FOR_WEEK * NUM_OF_WEEK is very simple computation to know exact offset.
My problem is this:
First I got milliseconds value from base date. And I set the milliseconds to another calendar object. I expected same date from that object. But actually it was different date.
CODE:...............
Here is my CODE:.........................

I'm running the basic HelloActivity from the SDK 2. samples. When I try Trace view in the DDMS prespective its generate the trace file but can not opened. "'/sdcard/com.google.android.apps.uploader.trace': Permission denied". Do I need a permission to write in the SD card? 4:38.380: INFO/dalvikvm(10434): Debugger has detached; object registry had 1 entries 11-20 21:34:38.380: DEBUG/dalvikvm(10434): VM cleaning up 11-20 21:34:38.411: ERROR/AndroidRuntime(10434): ERROR: thread attach failed 11-20 21:34:38.466: DEBUG/VoiceDialerReceiver(1225): onReceive Intent { act=android.intent.action.PACKAGE_ADDED dat=package:com.example.android.helloactivity flg=0x20000000 cmp=com.android.voicedialer/.VoiceDialerReceiver (has extras) } 11-20 21:34:38.466: DEBUG/dalvikvm(10434): LinearAlloc 0x0 used 636716 of 5242880 (12%) 11-20 21:34:38.490: WARN/ResourceType(1015): Resources don't contain package for resource number 0x7f080000 11-20 21:34:38.490: WARN/ResourceType(1015): Resources don't contain package for resource number.....

I tried to use traceview on a computer with a 64bit processor, the error I get is "architecture word width mismatch": I do use the 64bit version of Eclipse for development, I know SWT works on my computer. What do I need to do to make traceview work on my computer? For now, I copy the trace files to my laptop, which has a 32 bits architecture. android-sdk-linux_x86-1.5_r2/tools/lib/libswt-pi-gtk-3236.so: /home/ christine/java/android-sdk-linux_x86-1.5_r2/tools/lib/libswt-pi- gtk-3236.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1767) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1676).....

I have been trying to use traceview for profiling my Android app. So far I have gotten it to work on very small parts of the program. If I use it for bigger chunks it creates too much information (.trace file is too large) and I get an OutOfMemory (heap memory) error from the java compiler. I tried some tricks with setting higher min and max heap memory values but no luck. If anyone has used traceview with similar effects before. I would highly appreciate any tips you may have. Here are the details. First I am reproducing the error message: $ traceview.bat tmp.trace Exception in thread "main" java.lang.OutOfMemoryError:.....

We know that it's very convenient to use TraceView in Android java code to check the runtime of different chunks of code. Now I develop my app with NDK and I want to check the runtime of some native functions, but I found nothing in TraceView guide if it's possible to use this tool. Because I noticed that one of my native methods spent too much time and I want to dig out the more detailed root cause. Is there anybody know if we can use TraceView in native code?

I am getting complaints about my app's performance and want to get to the bottom of it. I am not really sure how to use traceview for that. I'd like to sketch how I used it and maybe you can give me some advice what to to differently and what to look for in the traceview output. The case: I have a list activity that lists articles. When clicking on one of the articles another activity is started that shows the article itself. I measure from the moment onClick() is entered on the ListActivity until the moment onResume() is about to be left in the Show Article Activity. I have two cases that I measure: "Cold" means the app is running and the ListActivity is started, but the Show Article Activity has not been called yet. "Warm" means the same, but the Show Article Activity has been called before during the runtime of the app. Here are the traces:.......

I'm using traceview to identify bottlenecks in my app. If I use the emulator, everything works fine. But when the device is used, no matter how long I run the app, traceview only gets the initial 5 seconds of my session and nothing more. I also noticed an error message in the console: Traceview: (<unknown>:10301): GLib-WARNING **: g_set_prgname() called multiple times. Have you ever experienced this problem?

I'm working with an OpenGL ES app in Android, but when I want to use traceview to profile my code, I always obtain the following error: ThreadData: 'android/XX/XX' call time (xxxxxxxx) is less than previous time (xxxxxxx) for thread '[3] main'. I've tried to call Debug.startMethodTracing() and stopMethodTracing() in different places of my code but it never works, anyone can help?

I'm calling Debug.startMethodTracing("fnord") and I'm getting a java.lang.RuntimeException: file open failed message. It looks like I'm supposed to have the android.permission.WRITE_EXTERNAL_STORAGE permission set. But how do you set that permission when you're debugging through Eclipse? Aren't permissions normally set at install time (which doesn't happen in a normal way when you're debugging)?

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?

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?

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

MotoDroid 2.2. Since 2.2, the auto-rotate screen goes haywire from time to time. I normally use the vertical format, easier to type, but when it switches, not much screen left, and I have to go back and back to start over again.

I just got the magic yesterday and so far I'm loving it. Just have a couple questions about texting. When I receive a text it usually tells me the time in eastern time though I'm pacific. However, my sent messages come up with the right time. This makes it so that threaded sms is kind of useless. Everything is all out of whack. Also, every once in a while it just won't even give me a time and there has been once or twice(after fiddling with it for a bit) that it gave me the right time but it just went back to the wrong time right after. Could this be a problem with the phone or is it rogers' fault? I'm assuming it's getting the time from the network and they have it wrong(meaning I can't fix it) but I just wanted to see if anyone else has had this problem.
Also, is there any way to make it vibrate when I receive a text? I feel dumb for asking this as it seems like it should be something really obvious but I can't seem to find it anywhere.

I recently received an LG optimus f3 with android 4.1.2.
After activating the phone, it displayed the correct date and time for my time zone, so I didn't mess around with settings to reset the time, as I would with any other device.
However, I've noticed that the time changes to exactly an hour ahead, before changing itself back several minutes later.
I went to settings > date and time, but 24 hour time and selecting a date format are the only options listed.
I prefer to leave mobile data off when I am at home and can use the wi-fi. Is it necessary to have mobile data turned on, so the phone can receive the time from a cell tower, or is there a way I can set an internal clock?

When i'm connected to my router at home via wifi, the connection randomly drops from time to time. My laptop and TV is fine which are both running via the internet. The setting is set to stay connected always, even when the screen goes black.
Does anyone have a resolution for this? Perhaps static IP? if this is the answer, what should the settings be?

I was having the waketime/sleeptime problem that many, many folks have reported and my battery life was obviously crap...and took forever to charge as has also been noted. I had already turned off all the auto-update stuff that I did when I first got the phone. Then I read the many posts abut Facebook app being the problem, but when I tried that it turned out that I was still running the old version 1.2, so apparently that wasnt causing it on my Evo.
Not really wanting to do a factory reset, I thought I'd check for other app updates in case one of the other apps had 2.2 bug fixes. Ran a sync thru the AppBrain app, and it found three updates that I hadnt been notified of:
Once those updates were completed, my EVO immediately starting going to sleep as it used to. I watched it for a few hours after the update and it continued to show realistic numbers for wake vs. sleep. My battery was almost depleted at this point, so I powered it off, and did the battery pull for good measure before powering back on and plugging in to charge during the night. This was all late Thursday night. All day Friday my battery performed VERY well...much better than even during 2.1. I had it on charge most of the day while listening to Pandora at my desk. I unplugged it to go home and now checking it this morning, it's now been off charge for 14h 39m, show wake time of 33:44 vs. sleep time of 15:28, and shows 80% battery remaining! This whole scenario makes me wonder if one of those three apps had a similar bug to Facebook. If you have those...you might want to take a closer look.

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)
