[android-developers] Re: Refresh Imageview PLEASE HELP killing me!
You need to give control back to the EDT so it can draw the image.
The for loop needs to be in a non EDT thread.

[android-developers] Re: adb devices returns an empty list
Hello Argon,
IMHO you should switch to android-platform, as this kind of question
is out of scope of the android sdk.
And their you should provide by far more details. I.e. from where
comes
your platform, do you have the platform code, is the adbd started by
init.d,
can you see adbd using ps on the device and so on ?
Maybe your platform has no adb support ?

[android-developers] Is CursorAdapter ok to use?
Hi! I got an ANR in an application which used the CursorAdapter, and I started thinking if it's allowed to be used or not. It's pretty common to create a ListActivity (or just an Activity with a ListView) and set a CursorAdapter as adapter to it. However when the data set changes, the CursorAdapter gets the callback and calls requery (of it's enabled of course). However this requery could result in a database access, which is really bad in the main thread (like in my case).

Yes, there is another thread, doing DB access as well. But I'm wondering about the general case: in general, doing any DB access (even queries/reads) can cause ANRs (the filesystem can be blocked, another thread or even another process could access the same DB, etc).

Re: [android-developers] Re: Is CursorAdapter ok to use?
I've never had an issue with reading on the UI thread, and even doing an occasional small update (and my current project does use a database and content providers quite a bit). Speficially, CursorAdapter is intended to be used from the UI thread - its data fetching callbacks, getCount, getItemId, etc. - are typically called by ListView or some other AdapterView, and so run on the UI thread. On the other hand, if you are locking the database somewhere else, this can interfere with the above data access, which I believe is what's happening in your code. Can you change how your worker threads write to the database, so it takes less time? And why would you have another *process* accessing the database? -- Kostya 2011/4/4 space pal.sz...@gmail.com Yes, there is another thread, doing DB access as well. But I'm wondering about the general case: in general, doing any DB access (even queries/reads) can cause ANRs (the filesystem can be blocked, another thread or even another process could access the same DB, etc). So the question is: is CursorAdapter safe or not? Or what is the proper way of using it? /Pal On Apr 4, 10:08 am, Kostya Vasilyev kmans...@gmail.com wrote: Reading should be Ok, perhaph there is something unusual going on in your code? The last function on the stack is SqliteDatabase.lock - do you perhaps have a background thread that also locks the database for a long time? -- Kostya 2011/4/4 space pal.sz...@gmail.com Hi! I got an ANR in an application which used the CursorAdapter, and I started thinking if it's allowed to be used or not. It's pretty common to create a ListActivity (or just an Activity with a ListView) and set a CursorAdapter as adapter to it. However when the data set changes, the CursorAdapter gets the callback and calls requery (of it's enabled of course). However this requery could result in a database access, which is really bad in the main thread (like in my case). This is the stacktrace: android.database.sqlite.SQLiteDatabase.lock (SQLiteDatabase.java:378) android.database.sqlite.SQLiteQuery.fillWindow (SQLiteQuery.java:64) android.database.sqlite.SQLiteCursor.fillWindow (SQLiteCursor.java: 287) android.database.sqlite.SQLiteCursor.getCount (SQLiteCursor.java:268) android.database.CursorWrapper.getCount (CursorWrapper.java:70) android.database.MergeCursor.getCount (MergeCursor.java:61) android.widget.CursorAdapter.getCount (CursorAdapter.java:132) android.widget.HeaderViewListAdapter.getCount (HeaderViewListAdapter.java:132) android.widget.AdapterView$AdapterDataSetObserver.onChanged (AdapterView.java:782) android.database.DataSetObservable.notifyChanged (DataSetObservable.java:31) android.widget.BaseAdapter.notifyDataSetChanged (BaseAdapter.java:50) android.widget.CursorAdapter$MyDataSetObserver.onChanged (CursorAdapter.java:385) android.database.DataSetObservable.notifyChanged (DataSetObservable.java:31) android.database.AbstractCursor.requery (AbstractCursor.java:97) android.database.sqlite.SQLiteCursor.requery (SQLiteCursor.java:548) android.database.CursorWrapper.requery (CursorWrapper.java:211) android.database.MergeCursor.requery (MergeCursor.java:249) android.widget.CursorAdapter.onContentChanged (CursorAdapter.java:361) android.widget.CursorAdapter$ChangeObserver.onChange (CursorAdapter.java:377) android.database.ContentObserver$NotificationRunnable.run (ContentObserver.java:43) android.os.Handler.handleCallback (Handler.java:587) android.os.Handler.dispatchMessage (Handler.java:92) android.os.Looper.loop (Looper.java:123) android.app.ActivityThread.main (ActivityThread.java:3701) java.lang.reflect.Method.invokeNative java.lang.reflect.Method.invoke (Method.java:507) com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run (ZygoteInit.java:866) com.android.internal.os.ZygoteInit.main (ZygoteInit.java:624) dalvik.system.NativeStart.main So, does this mean that simply using CursorAdapter (with autoRequery=true) is dangerous?

Re: [android-developers] Re: does NFC in gingerbread support card simulate?
Hallo Zhihong, I'm not sure what function you mean. In the Tags app i see a tab called My tag where you can share your tag with other Android phones (or any device that supports Android's non-standard way of exchanging NDEF messages over LLCP). If that's what you mean, that's not card/tag emulation but Peer-to-peer mode (for direct communication between two NFC devices). br Michael On 02.04.2011 11:21 Zhihong GUO wrote: Hi Michael, The Tag application on Gingerbread have a fouction called smart poster, is it the card simulation? or just a tag emulation.

A test account lets you make purchases with your actual product ids, as a final test, before you publish the application.

Re: [android-developers] Tansition between two Images.
Hi,
If the background image is literally a background you could set it in XML
using android:background=@dfrawable/whatever. If it is for a small portion
of the screen you could put it in an image view and draw the animation on
top of it.

[android-developers] hide top alternative keys on soft keyboard
Hi all, I was wondering if it is possible to hide the top 'alternative' keys (!, ?, , ', :, all in yellow) on the soft keyboard before showing it. I would like to conserve as much space as possible and as these keys would never be used in this specific case, it would be great if I could tell android to hide them. This layout is from my Nexus S phone. Thanks, Rich -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: (File export) What's going on with my code?[NEED HELP]
A few things.
1 - For the target file, don't use SDCARD in your paths.
Environment.getExternalStorageDirectory already gives you the path to the
top-level directory (root) of the memory card.
Android 2.2 uses a path that's different from earlier versions, and you can
rely on this function to do right thing.
2 - For the source file, use this:
http://developer.android.com/reference/android/content/Context.html#openFileInput(java.lang.String
)
or
http://developer.android.com/reference/android/content/Context.html#openFileOutput(java.lang.String,
int)
Do not try to build the full path yourself (as in,
/data/data/package_name/files) - the path can be different depending on
the device and its Android version. The above functions already take care of
that.
You already have code to read your data files (to populate the list view),
just do it the same way.

Re: [android-developers] read character unicode form sqlite
2011/4/4 lbendlin l...@bendlin.us It doesn't actually matter how you store it as under the hood SQLite stores everything as string. You can dso dirty type conversion tricks when reading. It does not store everything as a string. There are native types for integer, real and BLOB, in addition to text. What you're probably refering to is that Android SQlite classes always bind SQL parameters as strings. From my experience SQLite uses ANSI strings though so in order to read your Unicode data back you actually have to use byte arrays for reading, and then convert the byte array to unicode string. What the OP showed is an example of two bytes per character, misrepresented as an ANSI string. Maybe on other platforms (can't speak for those). On Android, my current project stores and retrieves values as Strings, which can contain Western European and Cyrillic characters. I specifically tested this with a set of charcters that, taken together, can only be represented as Unicode. It works, and no data loss occurs. Perhaps the OP actually stores strings as byte arrays, and has mismatched conversions between storing and retrieving? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: does NFC in gingerbread support card simulate?
Hallo JMC, I think there is a big misunderstanding out there of what card emulation is (and what it is not!). First of all, NFC has three different communication modes: * Reader/writer mode, * Peer-to-peer mode, and * Card-emulation mode *Reader/writer mode* is used to access NFC tag (i.e. tags that comply to the tag formats specified by the NFC Forum and contain NDEF data). Moreover, this modes provides compatibility to existing RFID (13.56MHz, inductive, proximity coupling) card infrastructures (i.e. you can interact with contactless smart (and memory) cards, like MIFARE, ePassports, ...) The Nexus S supports reader/writer mode for 3 (4) contactless standards: - ISO/IEC 14443 Type A (e.g. MIFARE) and Type B - JIS X 6319-4 (that's FeliCa) - ISO/IEC 15693 (that's vicinity coupling cards, which is not NFC but uses a similar communication technique also in 13.56 MHz) *Peer-to-peer mode* is used for direct communication between two NFC devices (e.g. two mobile phones, but an NFC device can be pretty much anything). This mode lifts the restrictions imposed by an active reader -- passive card system. Thus, in a classic RFID/smart card system there is a reader device that starts and controls the communication with one or multiple cards, and cards that process commands received by reader. Whereas, in a peer-to-peer system any device can start (and control) the communication with any other device. Peer-to-peer mode is used to exchange any data between NFC devices. This data can be as simple as NDEF messages, but it's even possible to tunnel other network protocols like IP over a peer-to-peer link. The Nexus S supports the peer-to-peer protocol (NFC-DEP, ISO/IEC 18092) with LLCP (NFC Logical Link Control Protocol) on top. With the current API level only a simple exchange of NDEF messages (with Android's proprietary protocol on top of LLCP) is possible. *Card-emulation mode* is used to emulate a contactless smart card with an NFC device. This mode provides compatibility to existing RFID (13.56MHz, inductive, proximity coupling) reader infrastructures. An NFC device in card-emulation mode acts the same as any real contactless smart card. With card emulation it is important to notice the difference between a _contactless smart card_ and an _NFC tag_: - An NFC tag is a contactless transponder that has a certain memory layout and contains standardized data elements (NDEF messages). Four such layouts are defined by the NFC Forum (tag types 1 to 4). Tag type 1 is based on Innovision's Jewel tags, tag type 2 is based on NXP's MIFARE Ultralight. So I would not consider these two smart cards (they are more like simple memory cards). Tag type 3 is based on FeliCa and tag type 4 is based on the ISO/IEC 7816-4 smart card standard. Therefore, the latter certainly are smart cards. Yet, in this case an NFC tag is a smart card with a specific file layout (i.e. a card that contains the NDEF application). Besides the standardized NFC tag formats, vendors like NXP have created guidelines for using their contactless card technologies (e.g. MIFARE Classic) as NFC tags. An NFC tag is only data storage and doesn't have (may have but not use) special security features like data encryption, ... - A smart card can be much more than an NFC tag. A smart card can contain, for instance, a credit/debit card application, a ticketing application for public transport ... These applications have even existed before NFC. They DO NOT use the NDEF format to exchange data. Instead they use their own protocols (e.g. EMV for payment cards). Often they use special security features of smart cards (high security execution environment, highly secure data storage, cryptographic processing power ...) So the card-emulation mode allows the emulation of a contactless msart card (and not an NFC tag, although the smart card could *possibly* be used as NFC tag). As applications like credit cards typically have high security requirements, card emulation is not handled by the NFC device itself (i.e. the application processor of an NFC-enabled mobile phone). Instead, the NFC device has a dedicated hardware component (the so-called Secure Element) that handles all the card emulation. (*) (*) This is not entirely true, as some NFC controllers (like the PN544) would theoretically allow the emulation of ISO/IEC 14443-4 contactelss smart cards from the application processor. Yet, I don't know of any NFC phone that makes this functionality available to the user and I rather doubt that this will become available on the Nexus S. The Secure Element (SE) is typically a smart card itself. But instead of a normal contact/contactless smart card interface it has a connection to the NFC controller, which connects it to the NFC antenna. The Nexus S has an integrated SE (a SmartMX combined into the same package as the PN544 NFC

[android-developers] Problem Setting the Alpha Value for an Appwidget Background
I want to be able to set the alpha value for my appwidget's background so that I can control its transparency at runtime. After googling a bit, I came up with the following: Drawable bg = Resources.getSystem().getDrawable(R.drawable.appwidget_bg); bg.setAlpha(100); This code throws a Resources$NotFoundException. I'm sure I missed something blazingly obvious. Can someone tell me what it is? I suspect that the problem is since this is a widget I can only work with the remote views - even though I can get programmatic access to the resource as I did above. If that is the case, what is the remote view equivalent of what I am trying to do?

Re: [android-developers] Re: Can't communicate with NfcB tag
Hi, Please don't hijack threads - this is a different discussion so a different thread :) I can give you a quick answer. We scan a *lot* of tags, and also noticed a small set of NfcB/ISO-DEP cards that are a little tricky. You have to orient the antennas in just the right alignment, and it can take a couple of seconds. I asked our vendor and they explained that some NfcB cards are designed to work with limited RF sensitivity, since they are designed to work with fixed reader/writer infrastructure that has larger antennas and higher power. There is no way to adjust the power. I think you will find any NFC Forum tags will work fine however.

[android-developers]StringIndexOutOfBoundsException when calling ava.net.URL.openStream
Hi all,
I faced really nasty problem these days. I am executing the following
code
String destination = ;// this string is initialized before
coming here
URL url = null;
InputStream inputStream = null;
try {
url = new URL(destination);
inputStream = url.openStream();
// process the input stream
catch (IOException e) {
// handle the exception
} finally {
if (inputStream != null) {
inputStream.close();
}
}
This was working fine so far, but i start to receive to following
exception -

Re: [android-developers] Re: (Full) NFC support for Android (on a Nexus S, specifically)
We're not in a hurry to add public API's for Card Emulation. It is a developers nightmare because most NFC hardware will only support one type of card emulation technology. And there are at least 4 very common types (Felica, Mifare Classic, Mifare Desire, ISO-DEP). So a developer would need to understand all these types and the inter-operability issues, and choose which set of phones to write their application for. Not to mention dealing with multiple apps that all want to do card emulation. Take Mifare as an example, how would the user decide which application gets to control the Mifare Application Directory? Yes it is possible to construct a combination of API's and system UI that lets the user choose which application gets to do card emulation. But we have to introduce API complexity and, cognitive overhead for the user. As a third party developer, I highly encourage you to invest in peer-to-peer NFC. This can easily handle multiple applications, and is guaranteed to work across all Android phones.

[android-developers] Using RatingBar as Fav with one star
Hi, I tried implementing the Favourite functionaity for any Contacts using the RatingBar (having one Star). I set the rating a 0.0 initially (with stepSize as 1.0).

Hello Argon,
IMHO you should switch to android-platform, as this kind of question
is out of scope of the android sdk.
And their you should provide by far more details. I.e. from where
comes
your platform, do you have the platform code, is the adbd started by
init.d,
can you see adbd using ps on the device and so on ?
Maybe your platform has no adb support ?
Good luck ! Frank

[android-developers] Re: (Full) NFC support for Android (on a Nexus S, specifically)
Hey Nick, Thanks for your reply. The main problem with peer-to-peer NFC, is that it is not (yet) compatible with existing infrastructures that depend on RFID. Despite P2P NFC being easier to use for developers, and having more potential in the long run, and being - I presume - more secure (or, easier to make secure), I believe card emulation mode to be very important for the transition period due to its compatibility with RFID infrastructures out in the world today. I do understand the problems implementation of such API's in the public would cause, and the complications usage of the SE brings. But I believe the possibilities it would bring strongly outweigh the negative aspects associated with it. Regards, JMC On Apr 4, 4:15 pm, Nick Pelly n...@android.com wrote: We're not in a hurry to add public API's for Card Emulation. It is a developers nightmare because most NFC hardware will only support one type of card emulation technology. And there are at least 4 very common types (Felica, Mifare Classic, Mifare Desire, ISO-DEP). So a developer would need to understand all these types and the inter-operability issues, and choose which set of phones to write their application for. Not to mention dealing with multiple apps that all want to do card emulation. Take Mifare as an example, how would the user decide which application gets to control the Mifare Application Directory? Yes it is possible to construct a combination of API's and system UI that lets the user choose which application gets to do card emulation. But we have to introduce API complexity and, cognitive overhead for the user. As a third party developer, I highly encourage you to invest in peer-to-peer NFC. This can easily handle multiple applications, and is guaranteed to work across all Android phones.

[android-developers] Re: does NFC in gingerbread support card simulate?
Hey Michael, Thank you very much for you elaborate answer. As you suggested, I did not distinguish between smart cards and NFC tags. I have several follow-up questions regarding your answer. *Regarding P2P communication* - If I understand correctly, Android uses a proprietary protocol (which I believe is called com.android.npp) on top of LLCP as specified by the NFC Forum, which is a protocol on top of NFCIP-1 as specified in ISO 18092. I read in another discussion in this group about a spec on com.android.npp that's due to be published, is there any information as to a specific date for this publication? Or is there any other (documented) way for regular terminals or desktop readers to communicate with an Android phone over P2P? *Regarding Card Emulation* - How would installation of an application on the SE work? // How would permission be given, and to whom? I don't yet clearly see how this would work in practice. - And more specifically, how would one develop and test an application for the SE, if it requires permission by the SE owner. - You mentioned it's possible to emulate a card with some tweaking of the android source, how far could you go with this? Any pointers? Either way, thank you very much for you clarification on card emulation and the different NFC modes. Thanks, JMC On Apr 4, 2:07 pm, Michael Roland mi.rol...@gmail.com wrote: Hallo JMC, I think there is a big misunderstanding out there of whatcardemulation is (and what it is not!). First of all, NFC has three different communication modes: * Reader/writer mode, * Peer-to-peer mode, and *Card-emulationmode *Reader/writer mode* is used to access NFC tag (i.e. tags that comply to the tag formats specified by the NFC Forum and contain NDEF data). Moreover, this modes provides compatibility to existing RFID (13.56MHz, inductive, proximity coupling)cardinfrastructures (i.e. you can interact with contactless smart (and memory) cards, like MIFARE, ePassports, ...) The Nexus S supports reader/writer mode for 3 (4) contactless standards: - ISO/IEC 14443 Type A (e.g. MIFARE) and Type B - JIS X 6319-4 (that's FeliCa) - ISO/IEC 15693 (that's vicinity coupling cards, which is not NFC but uses a similar communication technique also in 13.56 MHz) *Peer-to-peer mode* is used for direct communication between two NFC devices (e.g. two mobile phones, but an NFC device can be pretty much anything). This mode lifts the restrictions imposed by an active reader -- passivecard system. Thus, in a classic RFID/smartcardsystem there is a reader device that starts and controls the communication with one or multiple cards, and cards that process commands received by reader. Whereas, in a peer-to-peer system any device can start (and control) the communication with any other device. Peer-to-peer mode is used to exchange any data between NFC devices. This data can be as simple as NDEF messages, but it's even possible to tunnel other network protocols like IP over a peer-to-peer link. The Nexus S supports the peer-to-peer protocol (NFC-DEP, ISO/IEC 18092) with LLCP (NFC Logical Link Control Protocol) on top. With the current API level only a simple exchange of NDEF messages (with Android's proprietary protocol on top of LLCP) is possible. *Card-emulationmode* is used to emulate a contactless smartcardwith an NFC device. This mode provides compatibility to existing RFID (13.56MHz, inductive, proximity coupling) reader infrastructures. An NFC device incard-emulationmode acts the same as any real contactless smartcard. Withcardemulationit is important to notice the difference between a _contactless smart card_ and an _NFC tag_: - An NFC tag is a contactless transponder that has a certain memory layout and contains standardized data elements (NDEF messages). Four such layouts are defined by the NFC Forum (tag types 1 to 4). Tag type 1 is based on Innovision's Jewel tags, tag type 2 is based on NXP's MIFARE Ultralight. So I would not consider these two smart cards (they are more like simple memory cards). Tag type 3 is based on FeliCa and tag type 4 is based on the ISO/IEC 7816-4 smartcardstandard. Therefore, the latter certainly are smart cards. Yet, in this case an NFC tag is a smartcardwith a specific file layout (i.e. acardthat contains the NDEF application). Besides the standardized NFC tag formats, vendors like NXP have created guidelines for using their contactlesscardtechnologies (e.g. MIFARE Classic) as NFC tags. An NFC tag is only data storage and doesn't have (may have but not use) special security features like data encryption, ... - A smartcardcan be much more than an NFC tag. A smartcardcan contain, for instance, a credit/debitcardapplication, a ticketing application for public transport ... These applications have even existed before NFC. They DO NOT use the NDEF format to exchange

Re: [android-developers] Re: Problem Setting the Alpha Value for an Appwidget Background
No. The widget is shown by a separate process, which loads drawables independently from your own.

Re: [android-developers] Re: (File export) What's going on with my code?[NEED HELP]
All the informations are here i guess! But there is not an example :( ! Plus, the examples in in the android dev site are not very clear! Please, can you help me(i'm noob, i know :( :D!) ? Thanks. Accessing files on external storage If you're using API Level 8 or greater, use getExternalFilesDir()http://developer.android.com/reference/android/content/Context.html#getExternalFilesDir(java.lang.String) to open a File http://developer.android.com/reference/java/io/File.html that represents the external storage directory where you should save your files. This method takes a type parameter that specifies the type of subdirectory you want, such as DIRECTORY_MUSIChttp://developer.android.com/reference/android/os/Environment.html#DIRECTORY_MUSIC and DIRECTORY_RINGTONEShttp://developer.android.com/reference/android/os/Environment.html#DIRECTORY_RINGTONES (pass null to receive the root of your application's file directory). This method will create the appropriate directory if necessary. By specifying the type of directory, you ensure that the Android's media scanner will properly categorize your files in the system (for example, ringtones are identified as ringtones and not music). If the user uninstalls your application, this directory and all its contents will be deleted. If you're using API Level 7 or lower, use getExternalStorageDirectory()http://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory(), to open a File http://developer.android.com/reference/java/io/File.html representing the root of the external storage. You should then write your data in the following directory: /Android/data/*package_name*/files/ The *package_name* is your Java-style package name, such as com.example.android.app. If the user's device is running API Level 8 or greater and they uninstall your application, this directory and all its contents will be deleted. 2011/4/4 TreKing treking...@gmail.com Review this: http://developer.android.com/guide/topics/data/data-storage.html http://developer.android.com/guide/topics/data/data-storage.htmlAnd Google Java IO.

[android-developers] Problem with activity group
Hi, I am using ActivityGroup class for one of my tab in my application. 1) There is a tab activity class calling the activitygroup class. 2) In activity group class i am calling one activity say Activity A which is a list view. 3) On Activity A item click, I am calling another activity say Activity B. I need to override the back button functionality in Activity A and Activity B. The problem which I am facing is on Activity A it is successfuly calling the overriden onBackButton method but on Activity B instead of overriding the back button method, it is calling the Tab Activity's back button method. I am not sure why? I even debugged the code and it never goes into the onbackbutton method of Activity B. To resolve this I even tried calling Activity A on back button press of tab activity which is required. But the flow come as it goes into activity A and then from there it goes directly to the First Activity. I am also using Alert Dialog Box in both of the activity and passing getParent() as context in the Alert Builder Dialog Box. Any help in this regard will be great.

Re: [android-developers]StringIndexOutOfBoundsException when calling ava.net.URL.openStream
The top-level function you're calling should indeed only throw those
exceptions that are specified in its signature. But if it calls other
classes / methods, there could be all kinds of exceptions, including runtime
errors (like the one you are facing). The former would be caught and
eventualy rethrown as specified by the top-level method, the latter can
lead to crashes.
I'd recommend you track down the source for your device's version of
HttpURLConnectionImpl.java, and take a look at the method mentioned in the
crash.

Hi all,
I faced really nasty problem these days. I am executing the following
code
String destination = ;// this string is initialized before
coming here
URL url = null;
InputStream inputStream = null;
try {
url = new URL(destination);
inputStream = url.openStream();
// process the input stream
catch (IOException e) {
// handle the exception
} finally {
if (inputStream != null) {
inputStream.close();
}
}
This was working fine so far, but i start to receive to following
exception -
Exception: java.lang.StringIndexOutOfBoundsException
Stack Trace :
java.lang.String.substring(String.java:1579)
org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl.getAuthorizationCredentials(HttpURLConnectionImpl.java:
1769)
org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl.doRequestInternal(HttpURLConnectionImpl.java:

org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl.doRequest(HttpURLConnectionImpl.java:

org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:
1153)
java.net.URL.openStream(URL.java:653)
I can't figure out for which values of 'destination' this exception is
thrown but i think this should never happen. The doc says the
openStream could throw only IOException. Any ideas ?
