I cannot quatify it but it is very noticeable and feels wrong when
playing my game. for example I play a sound when a piece is selected
however due to the lag the sound feel a bit out of place.
I will try to profile whats going on here. But I thought perhaps
someone may have had experienced this issue and come up with a
solution or workaround. I will try Matts idea of calculating the
volume before hand etc so I have to simply call soundPool.play(). Only
issue is that creates extra work i.e the sound volume might have
changed by the user meanwhile and also I'm very doubtful if it will
improve the lag.

[android-developers] Re: using soundPool but sound plays after a delay, sound is lagging

seems like I was wrong. Profiling shows 60% is spent on getting the
audio service and setting up the volume. Only 40% is spent on the
actual play function. So would seem like I setting up the volume
before hand is the way to go. I'll try that out and see how things go.

[android-developers] Re: using soundPool but sound plays after a delay, sound is lagging

ok i take it back, doesnt seem to make a difference. I think the lag
is in soundPool.play() itself.
Anyone got a workaround?

[android-developers] Re: using soundPool but sound plays after a delay, sound is lagging

Some feedback. I have noticed the sound is pretty instant and great
when there isn't another sound effect being played, otherwise the
delay is pretty bad. So say if I select a piece then the sound effect
is instant, however if I quickly select another piece as the sound is
being played, there is a very big noticeable delay before the sound
effect is heard.

[android-developers] Re: JDBC Driver for SQLiteDatabase

2009-12-19 Thread kristianlm


hi Elliott,

what exactly does it mean that the driver is unsupported and that
it shouldn't be used?

are you saying that JDBC should not be used at all? without
loading the jdbc driver with Class.forName() it isn't registered.

that concludes the code snippet in Joerg's post above is
not allowed?

Thanks a bunch,

On the device, the driver should be part of /system/framework/
core.jar.

   The SQLite driver is never used by the public API.  You pass the name
   as a String URI jdbc:sqlite: to getConnection().  That is the way
  JDBCalways works. The drivers are not part of the public API so the
   documentation is NOT missing anything regarding drivers.

   As far as I can see the only missing documentation is the URI
   jdbc:sqlite: as in Joerg's example -

               String db = jdbc:sqlite: + getFilesDir() + /test.db;
               Class.forName(SQLite.JDBCDriver);
               Connection conn = DriverManager.getConnection(db);

   The Class.forName() call is only necessary if Android does not
   automatically register the driver with DriverManager (I don't know if
   it does or not).

  Hi,

  I have a complex dialog-layout that has to be customized for small

  achieved by decreasing the height of several single Buttons and
  Textfields in the layout, each by a small amount.

  Of course much of the layout still stays the same, so I figured I
  could use the include/-tag. This was the idea:

  /res/layout/dialog_layout.xml                        == includes
  @layout/include_button_layout
  /res/layout/include_button_layout.xml
  /res/layout-small/include_button_layout.xml

  I figured that android would choose which button-layout to include at
  runtime. I couldn't get it to run, so I guess I was wrong. Could
  anyone confirm that this is not how it works?

  And if so, can anyone confirm whether this is the way to do it?

  /res/layout/dialog_layout.xml
     == includes @layout/include_above_buttons
     == includes @layout/include_button_layout_default
     == includes @layout/include_below_buttons

[android-developers] Re: ExpandableListView change background for child items

2009-12-19 Thread NoraBora

See the default android music player.

http://android.git.kernel.org/?p=platform/packages/apps/Music.git;a=blob;f=src/com/android/music/ArtistAlbumBrowserActivity.java

SimpleCursorTreeAdapter constructor has group layout and child layout.

for example,
group layout is here
http://android.git.kernel.org/?p=platform/packages/apps/Music.git;a=blob;f=res/layout-finger/track_list_item_group.xml

child layout is here
http://android.git.kernel.org/?p=platform/packages/apps/Music.git;a=blob;f=res/layout-finger/track_list_item_child.xml

you can set different background, text style or whatever you want.

I'm using ExpandableListView in my app and one of the complains is
that when expanded it's hard to visually distinguish where the child
item ends and next group item begins. So I would like to change
background of the child list item to the different shade. Brutal
attempts that I've made so far were based on directly changing
background color and text of the elements inside the child view item
but that leads to loss of hovers and highlights. So my question is -
what is a good strategy to achieve the above? I tried styles and
selectors but what really bums me out - that if I change one thing
then I need to add selectors for all combinations of focus/enabled
etc. when all I'm trying to do it to overwrite a single thing. Is
there a way to inherit parent style and set just a background for non-
focused, enabled child item?

How can I create a list where I can rearrange list items with dragging

Just like on the HTC Hero in the clocks app where you can rearrange

[android-developers] Select image resource dynamically

2009-12-19 Thread croco

Hi all,

I'm facing a problem,

I've added a folder of 350 images representing country flags in my
project

according the device country given by locale. Let's say fr for France

I would like set an image with fr.png which is in the res/drawable
folder. How to achieve this without maintaining an ugly map in the
code saying fr = R.drawable.fr etc etc .

Thank you for your help.

2009-12-19 Thread Sergiu Dogaru

you could try using Reflection, but that might be too complicated for
what you need.
What I would do is to place all of the images in the assets folder,
where you can retrieve them by name.
I think it's something like

Bitmap bmp = BitmapFactory.decodeStream(getResources().getAssets
().openFile(fr.png));

[android-developers] AsyncTask + NDK = Neverending process

2009-12-19 Thread Hunter Peress

Hi,  I'm running a pretty weird setup:

AsyncTask1.class - AsyncTask2.class -AsyncTask3 (inner class of
AsyncTask2) -NDK call (this one takes a long time).

Since the NDK takes so long, I want to give users the option to kill
the NDK call so that they can actually use the app. Basically, I keep
references of all the asynctask instances and I do:

aSyncTask1.getAsyncTask2().getAsyncTask3().cancel(true);

The true means mayInterruptIfRunning

but, lo and behold, the NDK process is still running. I don't care how
its done, but I need that NDK process to die when I ask it to. I'm
thinking about kill-9 it through a popen call..

Any ideas on how to kill this thing??

[android-developers] Re: passing paramters using ksoap2 to .net web service, always passes nulls (empty) values

2009-12-19 Thread android09

Hi wedyan,

I had also the same problem but finally i got the solution. I have
some steps for you, just go through it.
1) Remove PropertyInfo from your code and add this like:

SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME_TEMP);
// if you have 2 params in .net than add property this way. Suppose,
sum of two integers instead of PropertyInfo
request.addProperty(num, str1);
request.addProperty(b, str2);

2) Use HttpTransportSE instead of AndroidHttpTransport. and add
androidHttpTransport.setXmlVersionTag(?xml version=\1.0\ encoding=
\UTF-8\?);

3) To Display Result:
SoapPrimitive resultString = (SoapPrimitive)soapEnvelope.getResponse
();
System.out.println(resultString);
txtView.setText(Result is : +resultString);

Now, go through the above steps and also compare your application. I
hope you will find the solution. Let's hope.

Best Luck

NDK questions are best asked on the NDK Google Group:

http://groups.google.com/group/android-ndk

That being said, AsyncTask#cancel() will only stop a running thread if
the Java thread is interruptible, and it would not shock me if threads
tied up in NDK calls are not interruptible. Relying on Java thread
interruption is a serious code smell IMHO, NDK or not.

[android-developers] Re: OpenGL hardware requirements specification

2009-12-19 Thread shaun

Robert,  your right. Accessing the gl extensions at runtime will tell
us what effects we can use. But I Wa thinking that even if all the
extensions I want are available, maybe my program uses them all very
heavily and I want to limit that based on the class (horsepower) of
the gpu. I have not done much OpenGL programming so maybe this is not
really a case that comes up.

On Dec 18, 5:43 pm, Robert Green rbgrn@gmail.com wrote:
 Shaun,

 Most effects are things that you program so to enable/disable them,
 you have to do it in your own code.  Most other primitive features
 like fog, lights and texture filtering are all controllable in GL, so
 you wouldn't need any additional configuration options for your GPU.

 I'm comfortable saying that all we need is a relative class of GPUs
 that basically indicates how much raw power they have.  I'm trying to
 make my new game scale across all phones but I'm having a problem on
 the ones with software renderer.  No matter how far I drop the res of
 my textures or how basic I make things, I can't get over 10 fps on
 it.  That's where I'd like to draw the line and say that my game just
 can't be installed on it.  I know I can never provide a good
 experience on it, and thus the basic class system.

etc...

This way, we could specify that a game only works on class-2 and above
hardware.  It would make it MUCH easier for us to build high-quality
games targeted at gamer phones.

This in conjunction with a GL ES version would be perfect, however I
believe there will be some overlap.  My gut says that using the
proposed class system, one would expect class 2 and above GPUs to
support OpenGL ES 2.0.  Perhaps in the future some class 5 GPUs will
support 2.1 or 3.0 or whatever comes down the pipeline.

 accelerated OpenGL for lag-free rendering.

 Currently, we can use:

 uses-feature android:glEsVersion=integer /

 to specify the GLES version needed by the application. I assume that
 this requirement will be satisfied with the Android PixelFlinger (the
 software renderer) which is not what we want. Is there any way to
 specify a hardware accelerated OpenGL as a requirement in the
 manifest?

 Something like this would be great:

 uses-feature android:name=android.hardware.gpu /

I don't use XMLReader and I have no problems with SAX on Android, such

BufferedReader in=new BufferedReader(new

SAXParserFactory f=SAXParserFactory.newInstance();
SAXParser p=f.newSAXParser();
SearchParser parser=new SearchParser(null);
p.parse(new InputSource(in), parser);

(where SearchParser is a DefaultHandler subclass)

In your case, this would look like:

SAXParserFactory f=SAXParserFactory.newInstance();
SAXParser p=f.newSAXParser();
StringReader sr = new StringReader(xmlMessage);
InputSource is = new InputSource(sr);
p.parse(is, this);

Try something like that and see if it helps.

Re: [android-developers] Re: How to debug BadTokenException?

2009-12-19 Thread Mariano Kamp

Thanks for your help here.

I reas the bug report, but I am not quite sure what to make of it and what
the solution is.

In my case the user enters username/password and then I show a progress
monitor. When the user backs out or goes to home then I still want to
display the result, at least when an error occurred.

How is this to be accomplished?

Can I somehow find out beforehand if I will run in this error and then use
some other mean, say a toast, to at least notify the user that not all is
good?

 I don't know your specific case, but was easy to fix in my case, when
 I made sure that the dialogs/views/adapters that were being created
 are with the right context/activity.
 Pressing a back button usually finishes the activity, so if you have
 created for discussion sake created an static ListAdapter and passed
 it (this), an activity instance,

  this static adapter can no longer be used for showing dialogs etc.
 with the previous contexts. This behaviour gets complex depending on
 the launch modes/flags you set when starting an activity, and also
 whether you handle back button events.

 So token
 android.os.binderpr...@431d28f0 is not valid; is your activity
 running?  means your activity instance is no longer in History stack,
 but your are trying to use it somewhere.
 Since there is no knowing when your activity got finished and the
 sequence of steps that caused it, depending on different modes, you
 get sporadic reports.

Re: [android-developers] Re: parsing a string of XML with SAX.

Sorted, for anyone who was interested, the startElement and endElement
methods need to look like this:

public void endElement(String uri, String localName, String qName)throws
SAXException{
Log.i(###,start element);
}

2009/12/19 Edward Hinchliffe redders6...@googlemail.com

 In fact it seems that startDocment and endDocument are invoked when using
 my original code, with no warning about DTD handlers...
 so how do i get the other methods to be invoked??

 Using Mark's method, startDocument and endDocument are invoked, but
 never the elements...

Streets Of Boston wrote:
 Why is this a code-smell? Interrupting long-running threads that 'wait

 do stuff, pause or even stop and exit.

All of the following is IMHO.

In most cases, if you have to use wait()/cancel(), you're working at too
low of a level. There are reasons why countless engineers (e.g., Doug
Lea) have spent innumerable hours putting together java.util.concurrent
and kin -- getting threading right is *hard*. I would rather see
engineers use higher-order, highly-tested frameworks unless they are
actually trying to write such a higher-order framework.

I'm also not a fan of cancel()-ing threads you didn't create, though
that's what AsyncTask tries to allow, so apparently the core Android
team disagrees with me on that point.

Again, this is just my opinion.

You can also use something like:

Thanks, glad you posted this!  I used your WrapTTS class exactly as
you have it, but nfortunately, running it on the 1.5 emulator still
crashes (works great on 1.6 though).

Just doing what you did above, declaring the 2 global variables and
doing the checkAvailable() check, but the app force closes as soon as
the activity starts.  Below are the errors I am getting in LogCat
pertaining to this.  Any ideas?

 Hello,

 I was playing with addingTexttoSpeechto one of my applications and
 have been working with it using the Android1.6SDK. I was hoping to
 release the code such that it could be used on the earlier1.5OS
 since there are still quite a few of these around - and this is an
 upgrade. I realize that the TTS won't work on the1.5(at least not as
 I have it here), but I didn't want the app disappearing from the
 market for those devices.

 At any rate, after struggling for a while with this - a lot of trial
 and error - I came up with what now seems like a simple wrapper to
 allow for the backward compatibility. This was mostly taken from the
 Android blog entry

 http://android-developers.blogspot.com/2009/04/backward-compatibility...

 so I'm not exactly breaking new ground. Also, I'm not using all of the
 TTS features, hence the short list of wrapped methods, expand at
 your leisure. I'm attaching it here for anyone to use and anyone to
 comment on if I have done something really stupid. I'll comment back
 if my testing uncovers anything untoward.

 Wrapper Class:

 package com.mydomain.myapp;

 import java.util.HashMap;
 import java.util.Locale;

 import android.content.Context;
 import android.speech.tts.TextToSpeech;

 public class WrapTTS {

         private TextToSpeech mTTS;

         /* class initialization fails when this throws an exception */
         static {
                 try {
                         Class.forName(android.speech.tts.TextToSpeech);
                 } catch (Exception ex) {
                         throw new RuntimeException(ex);
                 }
         }

         /* calling here forces class initialization */
         public static void checkAvailable() {}

         private OnInitListener onInitListener = null;
         public interface OnInitListener {
                 public abstract void onInit(int status);
         }

         public WrapTTS(Context context, WrapTTS.OnInitListener listener) {
                 onInitListener = listener;
                 mTTS = new TextToSpeech(context,
                                 new TextToSpeech.OnInitListener() {

                                         @Override
                                         public void onInit(int status) {
                                                 onInitListener.onInit(status);
                                         }

                                 });

         }

         public int setSpeechRate(float speechRate) {
                 return mTTS.setSpeechRate(speechRate);
         }

         public void shutdown() {
                 mTTS.shutdown();
         }

         public int speak(Stringtext, int queueMode, HashMapString, String
 params) {
                 return mTTS.speak(text, queueMode, params);
         }

         public int setLanguage(Locale loc) {
                 return mTTS.setLanguage(loc);
         }

         public int isLanguageAvailable(Locale loc) {
                 return mTTS.isLanguageAvailable(loc);
         }

 }

 The following is used at the top of my main application.

         private WrapTTS mTts = null;
         private static boolean mTTSClassAvailable = false;

         /* establish whether the TextToSpeech class is available to us */

         static {
                 try {
                         WrapTTS.checkAvailable();
                         mTTSClassAvailable = true;
                 } catch (Throwable t) {
                         mTTSClassAvailable = false;
                 }
         }

 Use the mTTSClassAvailable to know whether to bother to even try to
 set up the engine.

 Hopefully it helps someone.

 Best Regards,
 Eric

[android-developers] Lifecycle states

2009-12-19 Thread stanlick

I have slept with the lifecycle diagram under my pillow for the past
several nights in hopes of resolving the dang thing.  Is it just me,
or are there too many states in the cycle?  Are some mutually
exclusive?  I am writing an application that utilizes
SharedPreferences for its persistence.  I had the following methods in
my activity and was getting very weird behavior when reloading the
saved preferences!  When I was saving the preferences from both
lifecycle methods, some key/value pairs  *WERE NOT* even in the Map
(as per debug break point).  Once I commented out the save in
onSaveInstanceState, mysteriously things started working fine.  It
appears there are thread safety issues concerning these two lifecycle
methods in particular.

@Override
protected void onPause() {
super.onPause();
savePreferences();
}

@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//savePreferences();
}

Peace,
Scott

[android-developers] Re: OpenGL: How to test for VBO support?

2009-12-19 Thread Robert Green

You are totally right - VBOs are part of 1.1.

G1 glGetString(GL10.GL_VERSION) = OpenGL ES 1.0-CM
Droid glGetString(GL10.GL_VERSION) = OpenGL ES 1.1-CM

So clearly I'm going to have to take this into consideration when
evaluating if the system supports the feature.  My next question is -
how do I get the gles version number?  This string is fine but doesn't
it give us a number somewhere instead that we can use?  I'd rather do
that than parse the number out of the string.

I tried glGetIntegerv(GL10.GL_VERSION)  but it returned 0.

 thinking about kill-9 it through a popen call..


(1) There is no NDK process.  It is just a Java/POSIX/Linux thread, in
your OWN process, which has called down into your native code.  If you don't
supply a way for that native code to find out it should terminate early and
cleanly exit, it isn't going to do so.  This is your responsibility.

(2) Killing a -thread- is utterly, completely broken.  What if that thread
happened to be down in the memory allocator with its lock held when you did
this?  Oops, you just hosed your entire process.

(3) mayInterruptIfRunning == calling interrupt() on the thread.  This is a
Java concept.  If your native thread is not doing anything to check for this
Java state, and back out of its operation when found, then it will not do
anything.  (Actually that largely holds true for Java as well.)

(4) There is really nothing special about Android in this stuff.  It is
important to understand standard Java threading, and/or POSIX threads and
use best practices for those.  For example, AsyncTask sits on top of
FutureTask (from the standard Java library) for its core implementation.

Re: [android-developers] Re: Alarm Wake Lock and Services

2009-12-19 Thread Dianne Hackborn

Yeah the repercussions of neglecting wake locks is largely luck -- for
example it is not uncommon for the device to be synchronizing in the
background, or receiving data, or doing something else that holds its own
wake lock, allowing you to run,  Also when plugged in to USB a wake lock is
held so the CPU will never go to sleep during that time.

Re: [android-developers] Lifecycle states

stanlick wrote:
 When I was saving the preferences from both
 lifecycle methods, some key/value pairs  *WERE NOT* even in the Map
 (as per debug break point).

What Map?

 It
 appears there are thread safety issues concerning these two lifecycle
 methods in particular.

They are both called on the main application thread. It seems difficult
to have thread safety issues with only one thread involved.

   @Override
   protected void onPause() {
   super.onPause();
   savePreferences();
   }
 
   @Override
   protected void onSaveInstanceState(Bundle outState) {
   super.onSaveInstanceState(outState);
   //savePreferences();
   }

onSaveInstanceState() can be thought of as bookmarking the current
state of the application, in case we need to come back to it (e.g.,
we're still on the activity stack but are being destroyed to reclaim
memory). I'd use it for things that are in memory, that should be in
memory if the activity is restarted, but otherwise are not needed on a
persistent basis.

For example, suppose you rolled your own word processor application,
bypassing EditText in the activity (e.g., so you could edit rich
documents). onPause() would be a fine place to store the current
document in a temp file, awaiting a possible Save operation from the
user -- if the app crashes, you could offer to recover the saved temp
file, for example. onSaveInstanceState() might hold the cursor position,
so that when you are recreated, you could reset the caret to a likely spot.

Hi, I have read your post already which is why I was playing around

If that is so then my question to Diane remains : how do I launch a
service explicitly, not using a string action, when its class is in
another APK ?

[android-developers] how to create int[] array containing blading colors

2009-12-19 Thread skink

hi,

i need to create int array containing two blading colors - e.g. for
green and red:

arr[0] == 0xff00ff00 // green
arr[1] == 0xff11ee00
arr[2] == 0xff22dd00
arr[3] == 0xff33cc00
arr[arr.length - 1] == 0x // red

i couldn't find any API for creating such an array, so i used
workaround:

created GradientDrawable, set its bounds to setBounds(0, 0, 100, 1)
then created Bitmap 100 x 1, drew GradientDrawable on this Bitmap and
finally gotPixels() from Bitmap

is there any more simple way?

thanks,
pskink

I have done a search on the Internet and a number of people have successfully

Does anyone here know how to get Google Maps to update correctly?

[android-developers] Droid AVD (2.0, WVGA854) resolution hell

2009-12-19 Thread greg1x

Hi!

I'm developing a 2D game I started on Android 1.0/1.1. It scales
itself to the actual surface size, so I had nothing to change because
of the newer higher-resolution devices.I have a G1, but I'd like to
test it on a Droid too, so I've created an AVD with Android 2.0,
WVGA854. I did not check the Scale display to real size option, so I
expected that I'll get the real WVGA dimensions on surfaceChanged.
It doesn't happen like this. My application receives strange width/
height values on surfaceChanged.
Width is 569. (height is also very low)
Shouldn't it be around 854?
So, my application draws/scales itself to a smaller screen and then
the emulator seems to stretch the lower resolution surface to 854
pixels. (not even 854, in Photoshop I measured ~866 instead)
It means that I get an awfully-looking low resolution app on a big
screen.

How can I avoid this, so my application gets the real screen size on
surfaceChanged?

Thank you!

[android-developers] Re: BitmapFactory: decoder-decode returned false

2009-12-19 Thread Mike M

I posted a response to the above link from Stefan

 I found at 
http://groups.google.com/group/android-developers/browse_thread/thread/171b8bf35dbbed96/c3ec5f45436ceec8?lnk=raot.
(thanks Nilesh).  You need to add BufferedHttpEntity bufHttpEntity =
new BufferedHttpEntity(entity); 


Here was my previous code:



conn = (HttpURLConnection) bitmapUrl.openConnection();
conn.connect();
is = conn.getInputStream();
//bis = new BufferedInputStream(is);
//bm = BitmapFactory.decodeStream(bis);
bm = BitmapFactory.decodeStream(is);



And her is the code that works:


HttpGet httpRequest = null;

try {
httpRequest = new HttpGet(bitmapUrl.toURI());
} catch (URISyntaxException e) {
e.printStackTrace();
}

HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = (HttpResponse) httpclient.execute
(httpRequest);

HttpEntity entity = response.getEntity();
BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity
(entity);
InputStream instream = bufHttpEntity.getContent();
bm = BitmapFactory.decodeStream(instream);



I have a page that download around 40 images, and you can refresh to
see the most recent photos.  I would have almost half fail with the
decoder-decode returned false error.  With the above code, I have
had no problems.

Thanks

[android-developers] ViewFlipper.showNext() not working in timer

I have some webimageviews inside a viewflipper, and I am setting a
timer so that I can play a slideshow of the images.  The problem is
the timer function is getting called but the view is not actually
advancing.  If I call the viewFlipper.showNext outside of the timer,
the image advances, but not inside the timer.  I can't use
viewFlipper.startFlipping because each time it flips I want to
download a new image in the background.

Here's my some of the code:

  public void playSlideshow() {
Timer updateProgressTimer = null;
updateProgressTimer = new Timer();
int delay = 5000; // delay for 5 sec.

int period = 5000; // repeat every sec.

updateProgressTimer.scheduleAtFixedRate(new TimerTask() {

public void run() {
System.out.println(done);
moveRight(viewFlipper);
}

}, delay, period);

}
}

public void moveRight(ViewFlipper vf) {
Log.v(moving right, Integer.toString(imageCounter));
Log.v(moving right child, Integer.toString(vf.getDisplayedChild

[android-developers] drivers for linux but can I install on my Droid

Hi,

I have access to a nifty new external device and drivers are available
for linux but the dependency on hardware is not clearly described.

i.e.  on the driver download page
Requires Linux Kernal 2.6+.

As I understand Droid I would have to have a rooted phone in order to
install - am I right - anyone?
But even if I had rooted my Droid, should I expect the Droid chip/
hardware to be compatible with the drivers that are distributed by
this external device vendor?

Thanks! (before I start rooting around)

[android-developers] Re: OpenGL: How to test for VBO support?

2009-12-19 Thread Robert Green

Just found the official docs - I guess that is the string you have to
parse, according to this - 
http://www.khronos.org/opengles/sdk/1.1/docs/man/glGetString.xml

Is anyone keeping a running count of how many questions I ask and self-
answer in this group?  I should look for 5 minutes before asking next
time.

On Dec 19, 1:00 pm, Robert Green rbgrn@gmail.com wrote:
 You are totally right - VBOs are part of 1.1.

 G1 glGetString(GL10.GL_VERSION) = OpenGL ES 1.0-CM
 Droid glGetString(GL10.GL_VERSION) = OpenGL ES 1.1-CM

 So clearly I'm going to have to take this into consideration when
 evaluating if the system supports the feature.  My next question is -
 how do I get the gles version number?  This string is fine but doesn't
 it give us a number somewhere instead that we can use?  I'd rather do
 that than parse the number out of the string.

 I tried glGetIntegerv(GL10.GL_VERSION)  but it returned 0.

[android-developers] Droid - won't rotate image captured from camera? (Camera.Parameters)

Hi,

I'm using this camera code to ask the camera to rotate the captured
image data:

  Camera.Parameters params = camera.getParameters();
  params.set(rotation, 0);
  camera.setParameters(params);

this seems to work on all phones, except the Droid. Has anyone else
seen this? The image data is always landscape, however, the native
camera app produces portrait images ok. I wonder if the Droid will
only respect the new Camera.Parameters.setRotation() method, but this
seems to only be available in sdk level 5?

Thanks

 What Map?

  It
  appears there are thread safety issues concerning these two lifecycle

 They are both called on the main application thread. It seems difficult
 to have thread safety issues with only one thread involved.

    �...@override

             super.onPause();
             savePreferences();

    �...@override
     protected void onSaveInstanceState(Bundle outState) {
             super.onSaveInstanceState(outState);
             //savePreferences();
     }

 onSaveInstanceState() can be thought of as bookmarking the current
 state of the application, in case we need to come back to it (e.g.,
 we're still on the activity stack but are being destroyed to reclaim
 memory). I'd use it for things that are in memory, that should be in
 memory if the activity is restarted, but otherwise are not needed on a
 persistent basis.

 For example, suppose you rolled your own word processor application,
 bypassing EditText in the activity (e.g., so you could edit rich
 documents). onPause() would be a fine place to store the current
 document in a temp file, awaiting a possible Save operation from the
 user -- if the app crashes, you could offer to recover the saved temp
 file, for example. onSaveInstanceState() might hold the cursor position,
 so that when you are recreated, you could reset the caret to a likely spot.

Is it absolutely crucial that your users have the most recent update the
second it's put out? If not, don't worry about this. Put your update out and
let the users discover it on their own, either if the Market actually works
and notifies them or if they go check for updates manually.

Otherwise you'll have to suck it up and write some version checking code.
This can't be that hard. Check a file on a web server, do a compare with the
current version, notify the user with an alert that a new version is
available and start the Market with your app when the user clicks the
notification.

Why even bother with the manifest?

Because without a higher version number the Market won't know there's an
update available. And you won't even be allowed to publish via the Market
unless the version code is higher than what's already there.

If you need your users to know when new updates are available, best bet

[android-developers] Re: Phonestatelistener dies after a while .... can it be kept alive?

2009-12-19 Thread henca

 TelephonyManager tm = (TelephonyManager)getSystemService
 (TELEPHONY_SERVICE);
                 tm.listen(mPhoneListener, PhoneStateListener.LISTEN_NONE);

 This seems to work for a while but then fails to fire after - say an
 hour.

This sounds very much like a problem I have and wrote about at
http://www.anddev.org/crash_recovery_makes_my_widget_useless-t9163.html

 I have tried relaunching the listening in a timertask every 60 seconds
 but this does not seem to work.

Yep :-), I have also tried to use a timertask and that get lost as
well as the PhoneStateListener together with some other global
variables.

 Is there a way of keeping a listener alive for a long period of time.

I wish I knew. The timertask idea might work if the timertask is
replaced with an AlarmManager. However, I still don't like the idea to
do periodic checks to see if something has become broken. Those
periodic checks will consume battery if done often but if done seldom
there is instead a bigger risk of not having a working
PhoneStateListener when the phone state changes.

 I can only assume  the system is garbage collecting it.

According to my studies of the logs it seems as if the
PhoneStateListener disappears because the application crashes and then
is recovered in a less useful state.

[android-developers] POST attempts fail every other try?

Hi,

Has anyone else experienced an odd behavior with HttpUrlConnection,
using https, a POST request, and image data? I'm in a situation where
the first time I POST my data, everything goes through to the web
server fine. Next time I post, this call:

HttpURLConnection conn = (HttpURLConnection) new URL
(strUrl).openConnection();

returns immediately, with 'conn' initialized and usable, however no
output is actually written - and the response from the web server is
empty. The result code is -1.

The next time I run the post, everything works fine again. Repeats in
that cycle forever:

 1) post works fine
 2) no good, doesn't actually open connection, and just returns an
empty string.
 3) post works fine
 4) no good, doesn't actually open connection, and just returns an
empty string.
 .. etc ..

this is all from within the same thread, same app - I just made a
dummy activity that has a single button and posts the data to the web
server when clicked.

This is posting to a large 3rd party site. I tried self-signing my own
cert, and pointed to my own test php script on my own server. Same
behavior. Every other post fails like this, no error message /
exception, nothing.

I also ran a proxy (Charles proxy) with the emulator. I can see that
on the failed attempts, no connection is made at all. So it seems like
something is going on inside the android system - a network connection
isn't even attempted. This is a really bizarre problem.

Thanks

  thinking about kill-9 it through a popen call..

 (1) There is no NDK process.  It is just a Java/POSIX/Linux thread, in
 your OWN process, which has called down into your native code.  If you don't
 supply a way for that native code to find out it should terminate early and
 cleanly exit, it isn't going to do so.  This is your responsibility.

 (2) Killing a -thread- is utterly, completely broken.  What if that thread
 happened to be down in the memory allocator with its lock held when you did
 this?  Oops, you just hosed your entire process.

 (3) mayInterruptIfRunning == calling interrupt() on the thread.  This is a
 Java concept.  If your native thread is not doing anything to check for this
 Java state, and back out of its operation when found, then it will not do
 anything.  (Actually that largely holds true for Java as well.)

 (4) There is really nothing special about Android in this stuff.  It is
 important to understand standard Java threading, and/or POSIX threads and
 use best practices for those.  For example, AsyncTask sits on top of
 FutureTask (from the standard Java library) for its core implementation.

 Hi All,

 Has anyone been successful showing a notification, starting an

 All three of these actions can be done with the emulator running 2.0,
 but will not run from the Droid.  I don't receive any type of
 notification that these actions fail on the Droid.  Although, every
 action works when a call is *not* active.  Missed calls during a call
 *do* show up in the notification bar, so I am hoping there is a way.

 I understand that the notification bar can not be accessed by users
 during calls, but it would be nice if a notification could at least be
 delivered.

 I also understand the security and usability concerns of displaying a
 window or action during phone calls.  Although, there are a lot of
 users who would like actionable functionality based on calls.

 Thanks for any input,

There is usually a cyber-crime division in each state.  However, they

However, I would still report it.

 pixels. (not even 854, in Photoshop I measured ~866 instead)
 It means that I get an awfully-looking low resolution app on a big
 screen.

 How can I avoid this, so my application gets the real screen size on
 surfaceChanged?

 Thank you!

[android-developers] ($25 reward) GPS not triggering onLocationChanged

2009-12-19 Thread dapaintballer331

If somebody can get this to work for me, using an emulator on the 1.5
sdk, I will send them $25 via paypal if you need it. I am using the
android 1.5 emulator.

Problem: I see the satilite icon on the top of the phone, but when I
send the device multiple coordinates, is never runs the
onLocationChange method.

Assumptions: Ignore the WakefulIntentService. Its just a
modification of the service class, by Mark Murphy, that keeps the
service running.

Question: Why isn't the emulator / my phone triggering
onLocationChange, but displaying an icon signifying GPS is active when
onHandleIntent is called? (And until stopUpdates is called). And, what
can I do to fix this?



Code (FmiLocationManager.java):
=code=
package org.myProj;

import android.content.Context;
import android.content.Intent;
import android.location.LocationManager;
import android.location.Location;
import android.location.LocationListener;
import android.os.Bundle;
import android.os.IBinder;
import android.util.Log;
import android.location.Criteria;

public class FmiLocationManager extends WakefulIntentService
implements LocationListener
{
private LocationManager locationMan;
private LocationListener locationLis;


public FmiLocationManager()
{
super(FmiLocationManager);
}

@Override
protected void onHandleIntent(Intent intent) {
super.onHandleIntent(intent);

locationMan = (LocationManager) getSystemService
(Context.LOCATION_SERVICE);

locationMan.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
0, this);
String provider = gps; //(Available on the emulator, I tested 
it)
locationMan.requestLocationUpdates(
provider,
13000,
3,
this);
}

}



public void onStop()
{
stopUpdates();
}

public void stopUpdates()
{
if(locationLis != null)
locationMan.removeUpdates(locationLis);
}


@Override
public IBinder onBind(Intent intent) {
return null;
}


public void onLocationChanged(Location loc) {
Log.e(fmi,fmi new location received);
//NEVER gets sent.

   }

 public void onProviderDisabled(String provider) {
 }

public void onProviderEnabled(String provider) {
}

public void onStatusChanged(String provider, int status,
 Bundle extras) {
 }
}
==end code

Re: [android-developers] Re: I am a newbie...

2009-12-19 Thread Frank Weiss

Info about the USB driver is on the developer.android.com web site here:
http://developer.android.com/sdk/win-usb.html

It takes just a little effort to learn the Eclipse IDE, but it's well worth
it, IMO. To open the Debug perspective, choose Window + Other + Debug. Then
choose Run + Debug Configurations. Select Android Application and click
the New launch configuration button. Further info on Eclipse debug
perspective is OT for this mail list, get help from Eclipse support. Once
you have it going, you can launch your Android app in an AVD or on a device,
see what exceptions are thrown, set breakpoints, inspect your code
variables, view the logcat output, etc. This can also be done from the
command line Andorid SDK tools such as adb, etc., but many people find the
Eclipse UI more productive and easier to use.

You are totally right - VBOs are part of 1.1.

G1 glGetString(GL10.GL_VERSION) = OpenGL ES 1.0-CM
Droid glGetString(GL10.GL_VERSION) = OpenGL ES 1.1-CM

So clearly I'm going to have to take this into consideration when
evaluating if the system supports the feature. My next question is -
how do I get the gles version number? This string is fine but doesn't
it give us a number somewhere instead that we can use? I'd rather do
that than parse the number out of the string.

I tried glGetIntegerv(GL10.GL_VERSION) but it returned 0.

it's the only device I have that doesn't report a VBO extension but
the VBOs work perfectly on it so it clearly supports them. Hmm...

Normally I check the extensions for one that ends in
vertex_buffer_object but that's not going to work here. Is there a
better way of knowing?

[android-developers] Re: POST attempts fail every other try?

Hi Jeffrey,

Thanks for confirming this. When you switched to the HttpClient
equivalents, did you have to import all the additional external jars -
I guess that's actually if you want to do a multi-part post, like
here:

http://groups.google.com/group/android-developers/browse_thread/thread/e4230ed22c196772/222e1d3af8eca7b1?#222e1d3af8eca7b1

I'd prefer not to start importing all these additional jars, ugh. Just
wondering if that's what you ended up doing,

Thanks

Yes. I came to the conclusion that the sdk was re-using the ssl connection
internally but at some point the connection was released, but the sdk kept
trying to use it.

I never found a solution and ended up using the httpclient equivalents.

Sorry I don't know enough about http or ssl to give a better answer.

Hi,

Has anyone else experienced an odd behavior with HttpUrlConnection,
using https, a POST request, and image data? I'm in a situation where
the first time I POST my data, everything goes through to the web
server fine. Next time I post, this call:

HttpURLConnection conn = (HttpURLConnection) new URL
(strUrl).openConnection();

returns immediately, with 'conn' initialized and usable, however no
output is actually written - and the response from the web server is
empty. The result code is -1.

The next time I run the post, everything works fine again. Repeats in
that cycle forever:

1) post works fine
2) no good, doesn't actually open connection, and just returns an
empty string.
3) post works fine
4) no good, doesn't actually open connection, and just returns an
empty string.
.. etc ..

this is all from within the same thread, same app - I just made a
dummy activity that has a single button and posts the data to the web
server when clicked.

This is posting to a large 3rd party site. I tried self-signing my own
cert, and pointed to my own test php script on my own server. Same
behavior. Every other post fails like this, no error message /
exception, nothing.

I also ran a proxy (Charles proxy) with the emulator. I can see that
on the failed attempts, no connection is made at all. So it seems like
something is going on inside the android system - a network connection
isn't even attempted. This is a really bizarre problem.

Thanks

 try calling flush() just before stop, release. Otherwise I don't know
