have you tried my code?
did you use ogg files instead of mp3'
ogg files are mauch better handled by MediaPlayer so i didn't have
*any* gap
in fact, when using mp3 i noticed small delay between tracks

Thanks for the reply. Can you flesh it out a little? I see some examples that dont use override, so there must be a reason? Do I stick this in the activity or the view or the onCreate or ?? I get this event, and 'do some stuff' like increment a count and print it out. Then what? When I hit the key a 2nd time, does the count 'or' over the old count?

Re: [android-developers] Re: how to Play music from AudioTrack
Thanks skink,,
There is very small gaps in between playing of 2 files.May be MediaPlayer
takes milliseconds time to start in between.
when listening to continous stream,you can make out,,You feel like music is
not continuous.Itz stucking sometime.
In iphone,they have option of storing audio directly to stream and play from
it,so there is no need to start mediaplayer again and again.
Unfortunately we don't have such option in Android.

[android-developers] DRM support for Ringtones on Android
Hi, I am trying to create an application that downloads ringtones to the phone and I am trying to support Forward Locking on the downloaded ringtones. Currently I am saving the contents as .mp3 on externalDirectory.Reading forums and other articles online, it seems like android does have DRM 1.0 and DRM 2.0 support using libdrm1_jni.so or libdrm2_jini.so e.g http://groups.google.com/group/android-platform/browse_thread/thread/12a3083e9ed21d6f I have played around little bit with this. Approach that I tried 1. I have downloaded the package android.drm.mobile1 and tried to call one of its function DrmRawContent() from my app. Issues that this gives is, it loads one library which is libdrm1_jni.so but it depends on others libraries which i have trouble to load. Here is the snapshot: D/dalvikvm( 6176): Trying to load lib /system/lib/libdrm1_jni.so 0x46aaa218 D/dalvikvm( 6176): Added shared lib /system/lib/libdrm1_jni.so 0x46aaa218 D/dalvikvm( 6176): +++ not scanning '/system/lib/libwebcore.so' for 'nativeConstructDrmContent' (wrong CL) D/dalvikvm( 6176): +++ not scanning '/system/lib/libmedia_jni.so' for 'nativeConstructDrmContent' (wrong CL) D/dalvikvm( 6176): +++ not scanning '/system/lib/libexif.so' for 'nativeConstructDrmContent' (wrong CL) D/dalvikvm( 6176): +++ not scanning '/system/lib/libsrec_jni.so' for 'nativeConstructDrmContent' (wrong CL) W/dalvikvm( 6176): No implementation found for native Lmobile1/ DrmRawContent;.nativeConstructDrmContent (Ljava/io/InputStream;II)I Questions that I have: 1. Is there any approach I can follow to support DRM using the existing code from Android? 2. The approach I followed, is it correct or am I missing anything? 3. If there is nothing already available on Android, Can someone please point me to where I can find on "how to create DRM support" specially for Forwar Lock? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: how to crop an image in android 2.x
First, don't set the class-name.
Your customer's phone may not have this particular activity
(com.android.camera.CropImage) installed.
But this should not give you the 'permission denial' error.
Maybe the CROP action can only crop public images. You set yours to
PRIVATE.

Thanks, Tuhin, for your intrest. But I want to crop the image, not re-
scale the image, where user can select the area to be croped form the

[android-developers] Re: port forwarding
Never say never -- it would be appropriate for a mySQLAdmin tool, say, talking over wifi. Anyway, my answer to Mr. L. Newbie's question, is: 1. You could probably find and/or port such a thing. MySQL's Connector/ J is pure Java. It might rely on some standard J2SE stuff that's not present on Android, in which case you'd have to come up with substitutes. 2. GET/POST is *not* the only way -- but it is the best way, the tried and true way, and what most other people are doing. Google "RESTful" (I'm surprised it's that easy to get a good search result, but it is). The alternative would be to use SOAP, but I wouldn't do that unless you already know why you want to do that (such as compatibility with an existing service or environment). This will also drive the design of your application in a direction which is more mobile-friendly. It's not really a matter of mobile vs LAN -- really, I don't recommend the use of direct database connections except between tightly-coupled components -- such as between your web service, and its back-end database server. Doing direct SQL poses everything from security risks to temptations to depend on aspects of your data model which shouldn't be exposed, leading to massive compatibility problems, and the need to update all clients at the same timethe list of reasons goes on and on.

[android-developers] Re: How to style text in string array?
Thanks. That works. FWIW it does not work with ordinary String resources (non arrays) in 2.0.1 unless the gt/lt notation is used. So maybe the change was in 2.1. Further in 2.0.1 the tag doesn't work for Html.fromHtml although it does work when referenced in the XML layout as show above. (and I preseume and ) work with both Html.fromHtml and when String resources are referenced in layout.

[android-developers] Re: AudioRecord Class Problem: Callback is never called
Hi,
Last I checked the AudioRecord read is a blocking operation, you don't
need to have to "poll" for data..just set up a second thread that
constantly reads. It will read as fast as possible. The amount of
"blocking" in the read is the size of the buffer chosen

[android-developers] Re: Regarding expansion of google market
I must be missing something. What do you mean by the "expansion of google market"? I presume you're referring to Google's Marketplace? If you go to flurry.com or admob.com, you can find nice charts of the explosive growth in the Google Marketplace. New apps are added at a very high rate. So I'm guessing I'm not understanding what you mean by "expansion". Is this some promised expansion of capabilities? That would be most welcome! For example, being limited to just two screenshots does both the seller and the buyer a grave disservice.

Got it working. I think I'm off and running with Android development. I may have to pick up your book. Does it cover accessing data over the network? I'm thinking about exposing a RESTful service and having the app get its recipe data from that. Also considering having the app get its recipe data from Google or Amazon storage. Will have to consider caching recipes locally in case the user is temporarily without network connectivity.

[android-developers] 9-patch background image affects margins?
i have list views with image views and text views etc in them, and i'm trying to fix up a situation where the background image of a list element changes in the "pressed" state. if there's a straightforward way of doing that, please let me know! right now, i override onTouchEvent() in the topmost view, and also in those child views who don't just delegate to their parents -- which would be image views. i have to check for long clicks myself, but basically this scheme works. the list views are potentially different sizes depending on how much text is in the views etc, so i thought i would use a 9-patch as the background. however, when the background changes from flat white to the 9-patch, this seems to indent the view a bit -- ie give it margins. eh? if i change the image to a non-9-patch, the margins remain as they are. i've tried different sizes of 9-patch, from 320x150 or so down to 100x30 etc, no change. what's going on? thanks -- jason.vp.engineering.particle -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: How to style text in string array?
You are right it doesn't seem to work. Context.getString() strips out
the format tags. The documentation implies it should work but the
mechanism is not explained or it is a bug.
It does work with the XML directly like -
my name is sue
android:text="@string/foobar"

[android-developers] Re: Multitouch seems badly broken on Nexus One 2.1-update1
It's not so much an issue of gestures that may be impossible to recognize on certain screens but more that the API exposes functionality that is broken on all screens at the moment. Especially the coordinate flipping/confusion is something that can't be solved according to Dianne. And it is exactly this functionality (just tracking two fingers that are not close to each other on the screen) that is needed by us game developers to create more elaborate input schemes.

[android-developers] How can I configure TextView to draw text like an anchor

[android-developers] Prevent EditText focus
How can we prevent an edittext from getting focus and displaying the soft keyboard. I have an searchbox which should not be focussed by default and should have focus only when user clicks on it to enter something.

[android-developers] TextView, autoLink, and RemoteViews?
I have a TextView in an AppWidget where the text is set by a user. This text can include one or more URL links (i.e http:/ www.google.com). I want these URLs to be clickable and open the browser and go to whatever link was clicked. I have accomlished this partially.The code I have at this point is as follows: Intent clickIntent = new Intent(); clickIntent.setAction(Intent.ACTION_VIEW); clickIntent.setData(Uri.parse(textViewContent.toString())); clickIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); PendingIntent pendingIntentClick = PendingIntent.getActivity(context, 0, clickIntent, Intent.FLAG_ACTIVITY_NEW_TASK); views.setOnClickPendingIntent(R.id.widget_textview, pendingIntentClick); This code will open the browser and go to the correct URL if the content of the TextView contains only one link and no other links or text of any kind. This is because setData uses everything in the TextView as the URI. So, how would I go about having a method to tell if what was clicked is a link and which link it is if there are multiple links etc? Basically, I need the browser to open to the correct link that is clicked. Also, I have tried to go about this a different way. I tried using the XML property, android:autoLink="web", on the TextView of the AppWidget. This of course makes the URLs look like links and makes them clickable but an error occurs when a link is clicked. This error is as follows: "android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?" Using android:autoLink="web", the browser activity tries to start without any additional code (meaning the browser activity tries to start without the clickIntent code above). So, I do not know where I would add a FLAG_ACTIVITY_NEW_TASK in this case. Is there something I can do in the manifest.xml or another XML file? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: static context access
I presume you're setting this up in the Application, right? Indeed,
passing in the application at that point is just what I was about to
suggest.
Actually, I see nothing at all wrong with doing this. Just post it to
the main thread's Handler, and do everything except interception
there.
Just make sure that your code that runs in the main thread is bullet-
proof. (And anything it then passes off to other threads). That's just
a matter of having a catch (Throwable ex) {...} and logging, but not
passing on, any errors that occur.
I've done this sort of thing in a number of environments. I would even
go so far as to term this a cross-platform "best practice".
In terms of thread handling and communication, this is no different
than anything else you'd do in another thread. When you have something
to do in the normal context, you post it.
The one thing that CAN get tricky, is trying to recover from failures.
Another possibility is to set up your own Handler in your own thread.
Then you can do things like post Toast notifications, etc. while
leaving the main thread alone.
I've done this, and it worked, but then decided I didn't have any good
reason for it. However, this could be useful if the main thread is
stuck in a loop. But if you do it right, you can start off going to
the main thread, and switch to this later.

[android-developers] Re: system hangs while giving Android build
When I change the SDK version for a project, it hangs. I end up killing Eclipse and restarting, then doing a Clean, and all is fine. (I have to start remembering to turn off the automatic build in these cases). Perhaps you're seeing something similar? Maybe if a build tool gets an error at the wrong point in the process, Eclipse ends up waiting for something that's not going to happen?

[android-developers] rotate progress bar
HI, I am extending the normal android.widget.ProgressBar. I want to
make it vertical. This is my current onDraw Method
@Override
protected synchronized void onDraw(Canvas canvas) {
canvas.save();
canvas.rotate(90);
canvas.translate(0,-50);
super.onDraw(canvas);
canvas.restore();
}
This rotates it fine, however I am having alot of sizing issues. It
seems as though I have to set the width and the height of the control
to be the same thing or else I run into alot of clipping issues.
Basically, I want to have a progress bar that, once rotated, is 50dip
wide and fills the screen vertically. Can anyone think of a way to do
this?
Also, it doesn't seem to be actually drawing the progress properly,
but I will revisit that once I get the clipping sorted out.
Thanks
Jon

[android-developers] Re: Failed to fetch URL https://dl-ssl.google.com/android/repository/repository.xml
It seems you have quite unrealistic expectations of the community, and aren't even willing to help yourself. Let's see here: 1) Your sysadmins block direct web access to the Internet 2) You route your web requests through some unknown piece of software using one of several protocols to forward your requests, and 3) You expect the community to fix it all up for you? Who's being selfish? I have a solution for you: stop blaming the community. We can't help you with any of that. Talk to your sysadmins. They CAN help you. They may not be willing to. That doesn't make them the bad guys, either; I don't know their situation. But at least the have all the facts available to them, and access to investigate and fix. Finally: it would take you all of 2 minutes to look at repository.xml, and choose the download URL you want from that file. Just replace 'repository.xml' with the appropriate ... value. If you want to help yourself -- go home, or to a public library or a coffee shop or something, and download it onto a USB key. I think I can safely speak for the community, when I say the community doesn't like being flamed for things that are not the community's fault. On the other hand -- if, in the course of your investigations, you have SPECIFIC questions, with sufficient context, we're still glad to answer. The community doesn't hold grudges, much.

You will want to examine your Java stack trace, using adb logcat, DDMS,
or the DDMS perspective in Eclipse, to figure out where your crash is
and its cause.

You definitely want to use layout XML files for your rows and your activity, to make it easier to support different screen sizes and orientations. Otherwise, in a quick read, what you have here seems OK. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Training in US: 14-18 June 2010: http://bignerdranch.com -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Removing default application
hi, I am trying to write my own home application.I am trying to reuse the sample code as provided in the samples folder of the SDK. My idea is to try removing all the applications that are shown in the home application i.e. Desktop shortcuts and as well as the application listings when we press the menu button. I was going through the sample code (Home.java) where I found out that the applications are maintained in home application as [RECENTS] [FAVES] [BUTTON] . And Home.java one can see code as loadApplications(true); bindApplications(); bindFavorites(true); bindRecents(); bindButtons(); commenting out any one them or setting them as FALSE, leads to the launch of the default Home application not the one that I modified. Anybody has any idea why it is happening?Is it Android's some sort of security model?? Even does anybody have any idea how to add any new application as favourites at desktop from code level? Or whether this changes are possible at the SDK level or it has to done at the source code level ,where all the applications are part of the system image.

[android-developers] DOMException while cloning XML Node
Hi,
The cloneNode methon in the following minimal example works on java

Code 14 according to sdk dok means:
"NAMESPACE_ERR
If an attempt is made to create or change an object in a way which is
incorrect with regard to namespaces."
Has anybody an idea why this might be?
Thank you in advance!

[android-developers] Host is unresolved
Hi,
I encounter troubles trying to connect to a web site from behind a
proxy (128.0.0.26:8080) with my code using:
try
{
URL url = new URL("http://www.mysite.com/test.xml";);
InputSource source = new InputSource(url.openStream());
// do something with the retrieved XML data...
}
catch(Exception e)
{
Log.e(e.getMessage());
}
Launching the emulator through Eclipse with the command line options -
http-proxy 128.0.0.26:8080 or directly from the command line:
emulator @myavd1_5 -http-proxy 128.0.0.26:8080
I set the proxy options in the emulator as follows:
MENU -> Settings -> Wireless controls -> Mobile Network -> Access
Point Names -> T-Mobile US -> Proxy (128.0.0.26) and Port (8080).
All I get is:
Unknown host http://www.mysite.com, throwing UnknownHostException
Host is unresolved: www.mysite.com:80
Note if I launch the Browser in the emulator it tries to connect
automagically to www.google.com but fails saying:
Timeout waiting to connect to the web site.
But if I click on the emulator's MENU button and choose Go using
www.google.com or http://www.mysite.com/test.xml it works perfectly.
All firewalls and antivirus softwares have been disabled on my machine
and the proxy server that are both running Windows XP SP3.
I try forcing the DNS with the -dns-server command line option but
without any success either even when using OpenDNS DNS (208.67.222.222
and 220).
Did I miss something ?
Any helps would be greatly appreciated !

Gg.

[android-developers] Best Way To Implement An Activity That Lists Recipes
I'm working on my first Android app, and would appreciate any guidance to make sure I'm doing this the best way. Basically I want an Activity to list recipes. Eventually I'll have another Activity to display an individual recipe selected from the list, but I'm not worrying about that yet. I apologize if this is a really noob question! The list of recipes should show each recipe's title, description, rating, and date added. For each recipe in the list I'd like the title on the top left of the list entry, rating on the top right, description on the bottom left, and date added on the bottom right. I may want to add photo, icons representing properties of the recipe (e.g. vegetarian), etc. The makes me think that each item in the list should be a TableLayout. With all that in mind, here's what I'm planning to write: 1. Write class RecipesDataAdapter extends BaseAdapter. Override the getView() method to return an instance of TableLayout. Populate each instance of TableLayout with two TableRows, the first row containing cells for title and rating, and the second row containing cells for description and date added. For now I'll just pass the Recipe instances to the adapter in an array. 2. Write class ListRecipesActivity that extends ListActivity. Override the onCreate() method to obtain instances of the Recipe class and call the setListAdapter() method with an instance of the RecipesDataAdapter class. Notice that all this is done in code without any layout XML files. All the examples of Activities that I've seen use a layout XML file and call setContentView(R.layout.layout_name) but I'm not sure if I need to do that for this, or even how I would do that considering my main Activity is a list of non-trivial things (TableLayout). Please let me know if you think I'm on the right track, or if there is a better way to approach this problem.

[android-developers] AudioRecord Class Problem: Callback is never called
Hello Android Developers!
My Android Java Application needs to record audio data into the RAM
and process it. This is why I use the class "AudioRecord" and not the
"MediaRecorder" (records only to file).
Till now, I used a busy loop polling with "read()" for the audio data.
this has been working so far, but it peggs the CPU too much. Between
two polls, I put the thread to sleep to avoid 100% CPU usage. However,
this is not really a clean solution, since the time of the sleep is
not guaranteed and you must subtract a security time in order not to
loose audio snippets. This is not CPU optimal. I need as many free CPU
cycles as possible for a parallel running thread.
Now I implemented the recording using the
"OnRecordPositionUpdateListener". This looks very promising and the
right way to do it according the SDK Docs. Everything seems to work
(opening the audio device, read()ing the data etc.) but the Listner is
never called.
Does anybody know why?
Info: I am working with a real Device, not under the Emulator. The
Recording using a Busy Loop basically works (however not satifiying).
Only the Callback Listener is never called.
Here is a snippet from my Sourcecode:
__ snip!
public class myApplication extends Activity {
/* audio recording */
private static final int AUDIO_SAMPLE_FREQ = 16000;
private static final int AUDIO_BUFFER_BYTESIZE = AUDIO_SAMPLE_FREQ *
2 * 3; // = 3000ms
private static final int AUDIO_BUFFER_SAMPLEREAD_SIZE =
AUDIO_SAMPLE_FREQ / 10 * 2; // = 200ms
private short[] mAudioBuffer = null; // audio buffer
private int mSamplesRead; // how many samples are recently read
private AudioRecord mAudioRecorder; // Audio Recorder
...
private OnRecordPositionUpdateListener mRecordListener = new
OnRecordPositionUpdateListener() {
public void onPeriodicNotification(AudioRecord recorder) {
mSamplesRead = recorder.read(mAudioBuffer, 0,
AUDIO_BUFFER_SAMPLEREAD_SIZE);
if (mSamplesRead > 0) {
// do something here...
}
}
public void onMarkerReached(AudioRecord recorder) {
Error("What? Hu!? Where am I?");
}
};
...
public void onCreate(Bundle savedInstanceState) {
try {
mAudioRecorder = new AudioRecord(
android.media.MediaRecorder.AudioSource.MIC,
AUDIO_SAMPLE_FREQ,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
AUDIO_BUFFER_BYTESIZE);
} catch (Exception e) {
Error("Unable to init audio recording!");
}
mAudioBuffer = new short[AUDIO_BUFFER_SAMPLEREAD_SIZE];
mAudioRecorder.setPositionNotificationPeriod(AUDIO_BUFFER_SAMPLEREAD_SIZE);
mAudioRecorder.setRecordPositionUpdateListener(mRecordListener);
mAudioRecorder.startRecording();
/* test if I can read anything at all... (and yes, this here
works!) */
mSamplesRead = mAudioRecorder.read(mAudioBuffer, 0,
AUDIO_BUFFER_SAMPLEREAD_SIZE);
}
}
__ snip!

[android-developers] Intents
I am new to android development. To introduce myself to android
development, I am writing a simple game involving vikings.In this
game, I presently have to activities: one entitled "Vikings" for the
menu and one entitled "Campaign" for the game itself. The menu is
rather basic; it includes a button for quitting and a button for
beginning the game. As part of the code for newGame's onClick() event,
there is a call to the Campaign activity. Here is the code (Note that
NEW_GAME is defined in the Vikings class):
public void onClick(View v) {
/** TODO
* Call Campaign activity. */
Intent i = new Intent(Vikings.this, Campaign.class);
startActivityForResult(i, NEW_GAME);
}
I assume this should lead into the constructor for the Campaign class,
which so far looks like this:
@Override
public void onCreate(Bundle savedInstanceState) {
/** TODO */
super.onCreate(savedInstanceState);
setContentView(R.layout.campaign);
}
As far as I can tell, there should be nothing wrong with this code;
however, I get a crash whenever I try the program on either a physical
device or the emulator.

[android-developers] Re: Is there any changes in crop image activity
I think the answer is here:
http://developer.android.com/intl/de/guide/topics/manifest/activity-element.html#exported
In eclair, the CropImage activity has no intent-filter associated with
it, so it is not exported. This means it cannot be launched by
components of other applications. If this is what you are trying to
do, then that would explain the failure. Note that this *is*
different to previous versions of Android. See the declaration of the
CropImage activity with an intent-filter in release-1.0 here (line
86):
http://android.git.kernel.org/?p=platform/packages/apps/Camera.git;a=blob;f=AndroidManifest.xml;hb=release-1.0
...compared to the declaration of the CropImage activity *without* an
intent-filter in eclair here (line 71)

[android-developers] How to style text in string array?
Hi,
I have a string array and was trying to style certain parts of the

The array looks like this:
blabla\nblabla
The text is displayed in the textview like this:
tTitel.setText(Html.fromHtml(Text[ii]));
I tried it without Html.fromHtml too but this had no effect. The
styling tags do work if i use them directly in the code, like:
tTitel.setText(Html.fromHtml("blablablabla");
Any ideas how to style the text in an array??
Cheers,
Chris

[android-developers] Re: trying to launch Android 2's Gallery .. security exception
(Replying to a slightly old thread) The answer is here: http://developer.android.com/guide/topics/manifest/activity-element.html#exported In 1.0 the activity had an intent-filter, and was therefore exported (available to other components). In eclair it does not have an intent-filter, and is therefore *not* exported. See the difference between the 1.0 GalleryPicker activity declaration http://android.git.kernel.org/?p=platform/packages/apps/Camera.git;a=blob;f=AndroidManifest.xml;hb=release-1.0 and the 2.1: http://android.git.kernel.org/?p=platform/packages/apps/Camera.git;a=blob;f=AndroidManifest.xml;hb=eclair-release On Jan 27, 4:18 pm, "Mark Murphy" wrote: > > Understood.

[android-developers] Re: Inadvertent breakage by SDK going forward
Does this truly mean that even if I compile to the 1.6 platform, if my code implements a 2.1 callback method, that method will *never* be invoked on 1.6 devices but *will* be invoked on 2.1 devices? Even though I compiled to the 1.6 platform? That's crazy!
