Android :: Java.util.Date Vs Text.format.Time

Oct 26, 2010

Which one should I use java.util.Date or android.text.format.Time? It seems you can accomplish what one needs to do with either. What I need to do is at times get the current date and time and sometimes set a date and time specified by the user.

Android :: Java.util.Calendar - Time Difference

Jul 29, 2009

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.


Here is my CODE:.........................

Android :: Date / Time Format Change Broadcast

Oct 6, 2010

I am using android.intent.action.LOCALE_CHANGED to detect language changes and update my widgets. Is there something analogous for date and time format changes? I don't see anything, but I could be just blind.

HTC EVO 4G :: Incorrect Date / Time On Text Messages

Jul 16, 2010

For the past couple of weeks, I have been having problems with text messages on the Evo.For example, last night, I was sending texts to a friend, who replied back. His message said that it arrived on July 21, 2010 at 955pm.Clearly its not July 21, 2010, and when I sent/received the message, it was 630pm CST.I'm confused what is going on. Went to Sprint to have them look at it, they figured out the phone came from Best buy and wanted nothing to do with it, So, I'm here looking for answers.

Can I use thast class in my another file simply by importing the package along with the Class Name?

Android :: Java.util.TimerTask

Jan 15, 2010

Can I rely on Timer and TimerTask to work properly on Android?

I have a background Service with a single Timer, and I schedule (possibly multiple) TimerTask's via Timer.schedule()

At the beginning of each implemented method, I check the TimerTask.scheduledExecutionTime() and compare it with the current time. Sometimes things are fine, and the difference is a small number of ms. But sometimes things are nowhere near fine, and the invocation of my TimerTask is *way* late -- like multiple hours late.

Can an Android phone go into some deep sleep mode when it doesn't think anything is going on that would cause a TimerTask to be so late? Can I not reliably use TimerTask for scheduling events, and should I be using some Android-specific means (e.g. the AlarmManager, or a Handler) instead?

I have not found anything that says that java.util.TimerTask shouldn't be sufficient, the Android docs include no kinds of qualifiers, and this post (from Mark Murphy, who's written several good Android books) specifically mentions it as being available:

Android :: Java.util.Random Caching

Apr 19, 2010

That is the only thing I can think of. When I generate a random number (for the radius of a ball), after a while, the radius goes to one number and sticks that way. I've even tried setting the random number value to 0 before getting the random number, and java.util.Random must be at fault, it still gives the same random number. Here is an apk if you would like to try it yourself:

Here is a snippet of the code (I would rather not release the full source): <code> Random randomizer = new Random(System.currentTimeMillis()); int hw; hw = randomizer.nextInt(95-15+1)+15; </code>

Android :: Is Java.util.Scanner That Slow

Mar 15, 2010

In a Android application I want to use Scanner class to read a list of floats from a text file (it's a list of vertex coordinates for OpenGL). Exact code is:


It seems however that this is incredibly slow (it took 30 minutes to read 10,000 floats!) - as tested on the 2.1 emulator. What's going on?

I don't remember Scanner to be that slow when I used it on the PC (truth be told I never read more than 100 values before). Or is it something else, like reading from an asset input stream?

Android :: Weird Behavior Of Java.util.Preferences

Sep 25, 2009

My app needs to save its state before being killed, and since that state is really small (one Long), I've decided to use java.util.Preferences. I use it like the way I would be using in any Java application (and never had problems), though I am not sure this is the correct way here on Android platform: private static final Preferences prefs = Preferences.userNodeForPackage (WordChoice.class);

I update preferences in onPause() method, to ensure that data is always persisted no matter how my app ends: Here is that fragment of code: protected void onPause() { super.onPause(); prefs.putLong("currIndex", somePositiveValue); }

Android :: AsyncTask : Java.util.concurrent.RejectedExecutionException

Apr 7, 2010

I'm trying to launch a lot of remote connection retrieve picture on a server. To do this, I use AsyncTask.

This pics are displayed in a listview using adapter.

If I implement this in my adapter, images are retrieved but the display is bad (problem with index or something like that).

If I try to retrieve image when I build my object list (contained in my listview), I get the exception 04-07 13:35:57.744: ERROR/AndroidRuntime(4132):


What is this exception ? Why I can launch multiple asynctask in my listview (giving to me a bad result) and not in a simple object without having this issue ?

Android :: Util.SparseArray Space Time Complexity Properties

May 19, 2009

I need a map from int to certain objects. I wanted to use the HashMap, but in the documentation of SparseArray it says that SparseArray is intented to be *more efficient*:

However i think the documentation is not entirely correct and needs more info: When reviewing the sourcecode of SparseArray and comparing it with the HashMap i come to the following conclusion

Source code of Sparse Array: [url]

For SpareArray: Time complexity for reads and writes on a map of size N is log2(N) + 1,

However the time complexity for a HashMap of size N is C*N (where C is a constant) (according to the javadoc [url]

So maybe SparseArray is more efficient with respect to space complexity it is not for time complexity. So for programs that need high performance a HashMap may be better.

At least thats what i think. Am i right? Am i wrong? I need a very fast implementation for my game.

Android :: Class Initialization Issues Loading Java.util.logging.LogManager In Dalvik VM

Mar 18, 2010

I've done changes in an Android native library and installed a new system.img file but am now getting an unrelated Error on startup. I can get past it by swallowing the error but I wanted to know if anyone can explain what the issue is.

The Android implementation of claims that it is Forcing the LogManager to be initialized since its class init code performs necessary one-time setup. But this forced initialization results in a NoClassDefFoundError. I'm thinking that it has something to do with the class not having been preloaded by Zygote yet but am not that familiar with the whole class loaders and VM business.

Android :: Error: Java.lang.IllegalArgumentExcep­tion: Already Added - Lnet/ponder2/Util

Oct 27, 2009

I am using the Eclipse plugin and I have the above error. I know why it is occurring, it is because I want to override a class file in one of my imported jar files. I am including a new Util class before the jar file in question. I have tried it both as a simple .class file in my package hierarchy and I have tried putting it into another jar file and including it before the one to be overridden.

I would like it to behave like the Java classpath and use the first one it comes to when running through all the classes. I don't mind if dex wants to give me a warning that it is not using the second Util.class file but it should let me build my application. To build my app, I have to create a special jar file without the old Util.class in it. This is annoying as I would like to use the bog standard version so that others can use it with ease too.

Android :: Using Java.util.regex In Android Apps

Apr 2, 2010

In an Android app I have a utility class that I use to parse strings for 2 regEx's. I compile the 2 patterns in a static initializer so they only get compiled once, then activities can use the parsing methods statically.

This works fine except that the first time the class is accessed and loaded, and the static initializer compiles the pattern, the UI hangs for close to a MINUTE while it compiles the pattern! After the first time, it flies on all subsequent calls to parseString().

My regEx that I am using is rather large - 847 characters, but in a normal java webapp this is lightning fast. I am testing this so far only in the emulator with a 1.5 AVD.

Could this just be an emulator issue or is there some other reason that this pattern is taking so long to compile?

Jelly Bean :: Time Resets Itself And No Option To Manually Set Date And Time

Dec 30, 2013

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?

Android :: SQLite And Inserting Current Date In UTC Format

Nov 24, 2010

How do I use an SQL statement on an sqllite database to insert the current date in UTC. I found the NOW function but what format is that in? This will be on mobile devices so everyone will have a different locale, however, I need a standard time format because the device will compare the dates with my server. Also, is there a way to automatically update a 'modified' field when the data in the row is changed like you can in MySQL?
