Android :: Cannot Import Droid.text.util.Regex / Where Is It?

Aug 10, 2010

I'm developing an application and I want to use android.text.util.Regex.WEB_URL_PATTERN as the pattern for the Linkify. But, as I have notice, I cannot import android.text.util.Regex for some reason.

Why so? Is there a way to workaround this?

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?

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 : Way To Import GPX / KML With Text To Speech?

Apr 28, 2010

I'm cycling with friends of me (organized rides). but I still want to cycle those roads again. I record the track everytime with Cardiotrainer and I can export those workouts to an GPX or KML file. Is there a program were I can import the GPX or KML file and that program exports audio as "within 100 meters go left". A sort of GPS navigation but with audio export and the possibility to imort an GPX and/or KML file. It is necessary that the program can say it in audio and not only text because my Nexus One will be in my backpack.

General :: Import Text Messages From Blackberry 9900 To Android?

Jul 27, 2012

I am trying to move my text messages from my blackberry 9900 that I was using to my new android (G2) that I have transitioned to.I did find a program "blackberry 2 android" that sounds like it would be perfect but it gave me an error message so I am awaiting a reply from the developer.

I have never moved texts so I don't know how or what the exporting / importing process looks like. I know there is this app/site out there, but I would rather not buy an app for a one-time thing.

Android : Data And Format Them Using RegEx

Nov 17, 2010

I'm having three strings that I have to glue together.

I have an input string (string 1), which I have to run a regex (which has groups) on (string 2) and extract these groups to put them in a template (string 3) using backreferences.

A short example could be :

input: "foo1234bar5678"
regex: ".*?(d*).*?(d*).*"
template: "answer: $1 $2"

which should be expanded in "answer: 1234 5678".

I have been using java.util.regex.Pattern, but I can't figure out a way to do this with matchers. Obviously, replaceAll is not the expected behaviour, nor is append*.

Is there a way to do this nicely using the android API ?

EDIT:
Here is a basic implementation :

public static String genOutput(String regex, String input, String template) {
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(input);
if (m.find()) {
for (int i = 1; i <= m.groupCount(); i++) {
template = template.replaceAll("$" + i, m.group(in}} return template;}

Ok I know everyone is going to tell me not to use RegEx for parsing HTML, but I'm programming on Android and don't have ready access to an HTML parser (that I'm aware of). Besides, this is server generated HTML which should be more consistent than user-generated HTML. The regex looks like this: Pattern patternMP3 = Pattern.compile. Code...

Android :: Util Class In Java

I want to know about the util Class used in Java. I am currently working on one Application in Android where I need to used a class from one file to another different file. I was told to import it like "import com.android.utli.(ClassName)" here the "com.android.util" is a package name.

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 TimerTask.run() 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: http://74.118.194.50:84/Balls.apk

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:

CODE:.................

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 :: 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.

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); }

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*: http://developer.android.com/reference/android/util/SparseArray.html

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 : Write A Wifi Cracking Util For Phones / Monitor Mode Vs Multicast?

Jun 23, 2010

Considering writing a wifi cracking (wep, wpa) auditing tool for the android platform, but I am wondering if it is possible to do without a rooted phone.

I had thought it would be impossible to run on an unrooted phone due to the phones wifi chip ignoring packets not addressed to the phone. That is, without the ability to set the wifi chip to monitor mode many of these attacks wont work. I was surprised to learn that android supports multicast packets. That is, android phones can be set to receive packets not addressed to them.

My questions are: Does having a multicast lock mean I can receive all packets broadcast, or does it only apply to packets with a multicast flag (if such a thing exists)?

Is there a difference between monitor mode and multicast? Does the android api have a system for switching channels?

More generally I'm curious: Is anyone familar with other wifi cracking projects running on android (google searches turned up very little)?

What difficulties am I likely to run into?

This question is related to SO question Is there anyway to put Android WIFI (droid handset) into permiscuous monitoring mode?

Android :: Import IPhone Backup To Droid?

Jun 9, 2010

So recently I accidentally jumped in a pool with my iPhone in my pocket while on vacation. It's showing some signs of life and has working well enough for me to be in communication with the world, but overall it's more or less fucked. My contract with AT&T is up, so I jumped ship to Verizon and my HTC Incredible is arriving today. The phone stopped booting last night, however, so I have no way to access my contacts other than the iTunes backup I have on my computer. Is there any way to import these contacts into Android?

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 Logger.java 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.
