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.

I am attempting to integrate some previous libraries that we have within my new android project.
I have made several attempts including:
Importing the code as sub-projects (that are built using the android.jar)
Importing the code as jar files (from the built code)
Adding the files directly as part of my project
Reordering the dependencies
However for each one of these scenarios I keep getting the following exception thrown by the davlik compiler.
It is always picking the first class in the package (ie if I remove that class, it picks the next and so on).
It would appear to me that this is a compiler bug - somehow it's getting it's dependencies in a twist.
Anyone else experienced this? And/or have any ideas on how to get around this one?

I am wondering how to track down this IAE? It doesn't mention my code (com.newsrob.*) in the stack trace.
Is there anymore information that I can automatically gather and include in the bug reports to get a better understanding why this happens?

it has taken more than i expected to get the dev environment up and running - mostly a PATH issue which was solved using: http://groups.google.com/group/android-developers/browse_thread/threa...
My emulator now works (and i can run it and get the default android screen) however when i try to run the hello world sample code i get this error message:
An internal error occurred during: "Launching HelloAndroid". java.lang.NullPointerException

Im trying to display this listview, but I keep getting a: 07-17 21:14:22.233: ERROR/AndroidRuntime(349): java.lang.NullPointerException
I think I know what the problem is but I dont know how to fix it.
I have a String array which I will be using to be displayed in my list
CODE:.....
Dont worry the parser works great. the only problem I see with it is that the parser doesnt know how many strings the website will have so I am setting the String array in the parser to be very big: String substr[] = new String[250];
But I know that mostly there are only like 11 to 13 values that I will be storing in that array, the problem I think is when i do this:
CODE:..............
Since the String array is set to have up to 250 values in it and I only actually store say 12 then there are a null entries so when I run the code it shows me my list view, but when I get to the bottom of the view it force closes and the log tells me that there was nullpointer. I can tell how many entries I collected while I am parsing, but how do I tell my listview to only show say 12 items in the list so there wont be any null entries. or is there any other solution for my problem.
I tried doing what you said, but now I am getting a:
CODE:......
This is what I did:

When you get an error like the one below (Android 1.5), is it because there are too many nested ViewGroups, or because the total number of Views is too great? Are there any tricks to get around it while still keeping the same look to your app?

i am getting this error java.lang.NullPointerException at android.content.ContextWrapper.getPackageManager when am trying to get list of all installed applications on the device. Well let me explain what my program is doing. I have a server that starts when my application is started, and the client pings the server and asks to get a list of installed applications. The Server then asks the getPackageManager() and gets all the installed applications. But the getPackageManager returns the nullpointerexception. The Server is written in a java environment and is started from my android application. Could someone please tell me what am missing and why i am getting this error? hanks alot!!!Please find the code...

I have a service running that updates a notification in the notification bar when it recieves a message saying it has to be changed.
However I get the following error sometimes when the notification is to be updated
java.lang.IllegalArgumentException: contentIntent required
Here is my code:
Variable setup
code:............
NotificationManager Creation
code:..............
Notification Creation
code:.............
Update of Notification
code:...............
So something is happening my contentIntent somewhere along the line, would that be correct?
It is declared at the top of my Service class as a member variable and is not used anywhere else in the code apart from shown above, so where could it be getting reset to null?

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?

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:

I want to create a java.util.map in android from a resource. I want to do this because I have a lot of entries to populate into the java.util.map and I want to store the values in the res folder of the project in xml format.
Is there an effecient way to do this in android? My map will have around 2500 entries so I want to do this as effeciently as possible and I don't want to hard code them...

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>

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?

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:.........................

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):
CODE:.................
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 ?

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.

I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

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.

I have an app that runs perfect on 2.2 and 2.2 but always getting VerifyError on 1.6 while startup, I don't think that my app cannot run under 1.6 because I don't call any APIs that don't support 1.6. I'm really confused, does anybody has the same issue?

I have the following code which gets call in my main activity's onCreate method
public static ErrorReporter getInstance(){
if (instance == null){
instance = new ErrorReporter();
}
return instance;
}
Only on android 1.5 calling the above method causes java.lang.VerifyError. I am not able to figure out why this is happening.

I'm trying to add ScoreNinja, the global high score system, to my Android game, and it works fine when I load it on my phone, but when I release it into the wild, I got crash reports saying: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()
Here is part of the call stack:
android.os.Handler.<init>(Handler.java:121)
android.app.Dialog.<init>(Dialog.java:99)
android.app.AlertDialog.<init>(AlertDialog.java:65)
android.app.AlertDialog.<init>(AlertDialog.java:61)....
I thought the main thread had prepare() called automatically, and if not, why would it work fine for me but not anyone else?

I've got a strange problem here doing object de/serialization. In Java (JDK 1.6) I serialize some objects. In Android (SDK 1.1) I deserialize them. This work quite nice in general. In order to work with a server object (that uses Castor un/ marshalling) I do it like I always do. Same routines. Well, this time the file is only 172kb (my routines works pretty well with 2,4mb files) but the interlacing is quite deep. So it all starts with a class containing 2 ArrayLists. I tried de/serializing just ArrayList<String> and this works very well. But the XML file (which is unmarshalled with Castor and serialized in JDK) has 7000 lines. So I get this StackOverflowError....................

I'm getting this error: "Uncaught handler: thread main exiting due to uncaught exception java.lang.VerifyError" It's only happening on 1.6. Android 2.0 and up doesn't have any problems, but that's the main point of all. Can't catch the Error/Exception (VerifyError), and I know it's being caused by calling isInitialStickyBroadcast() which is not available in SDK 4, that's why it's wrapped in the SDK check. I just need this BroadcastReceiver to work on 2.0+ and not break in 1.6, it's an app in the market, the UNDOCK feature is needed for users on 2.0+ but obviously not in 1.6 but there is a fairly amount of users still on 1.6.
private BroadcastReceiver mUndockedReceiver = new BroadcastReceiver()
{
@Override
public void onReceive(Context context, Intent intent)
{
//FROM ECLAIR FORWARD, BEFORE DONUT THIS INTENT WAS NOT IMPLEMENTED
if (Build.VERSION.SDK_INT >= 5)
{
if (!isInitialStickyBroadcast()) {
int dockState = intent.getExtras().getInt("android.intent.extra.DOCK_STATE", 1);
if (dockState == 0)
{
finish();
}
}
}
}
};
