[android-developers] Help with LiveWallpaper and Camera
Hi,
I'm trying to understand camera development and started with a very simple
live wallpaper:
package com.example.LiveCamera;
import java.io.IOException;
import android.hardware.Camera;
import android.service.wallpaper.WallpaperService;
import android.util.Log;
import android.view.SurfaceHolder;
public class LiveCamera extends WallpaperService {
@Override
public Engine onCreateEngine() {
android.os.Debug.waitForDebugger();
return new LiveCameraEngine();
}
public class LiveCameraEngine extends Engine {
private Camera mCamera;
LiveCameraEngine() {
android.os.Debug.waitForDebugger();
}
@Override
public void onSurfaceCreated(SurfaceHolder holder) {
super.onSurfaceCreated(holder);
this.mCamera = Camera.open();
try {
this.mCamera.setPreviewDisplay(holder);
} catch (IOException e) {
Log.d(onSurfaceCreated,Error in
Camera.setPreviewDisplay+e);
}
}
@Override
public void onSurfaceChanged(SurfaceHolder holder, int format, int
w, int h) {
final Camera.Parameters parameters =
this.mCamera.getParameters();
parameters.setPreviewSize(w, h);
this.mCamera.setParameters(parameters);
this.mCamera.startPreview();
}
@Override
public void onSurfaceDestroyed(SurfaceHolder holder) {
super.onSurfaceDestroyed(holder);
// Surface will be destroyed when we return, so stop the
preview.
// Because the CameraDevice object is not a shared resource,
it's very
// important to release it when the activity is paused.
mCamera.stopPreview();
mCamera.release();
mCamera = null;
}
}
}
I always get this runtime error on the Camera.startPreview:
11-20 06:18:52.543: ERROR/AndroidRuntime(2054): java.lang.RuntimeException:
startPreview failed
11-20 06:18:52.543: ERROR/AndroidRuntime(2054): at
android.hardware.Camera.startPreview(Native Method)
11-20 06:18:52.543: ERROR/AndroidRuntime(2054): at
com.example.LiveCamera.LiveCamera$LiveCameraEngine.onSurfaceChanged(LiveCamera.java:46)
11-20 06:18:52.543: ERROR/AndroidRuntime(2054): at
android.service.wallpaper.WallpaperService$Engine.updateSurface(WallpaperService.java:566)
...
Is this related to be using it with a LiveWallpaper? I'm using android-7 as
target and I get the same error in the phone (Samsung Galaxy S) and on the
Emulator...
Any idea on what the error might be?
Thanks

[android-developers] Hello World doesn't work
Hey folks,
Couple of days back, I read some articles about Android and from that
moment I fell in love with Android development :) I explored
Developing Android apps for the past few days and done the
following,
* Installed the latest Android SDK i.e., 2.2 version. Also updated all
the installed packages using SDK manager
* Installed Eclipse IDE for Java EE developers
* Installed Android plugin for Eclipse
* Created AVD and selected the target platform as Android SDK 2.2
* Written a new HelloWorld program with the below code,
package com.example.helloandroid;
import android.app.Activity;
import android.os.Bundle;
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
When I try to run the code Hello World is not printed in the
emulator. Just the text Android blinks in the middle of the device/
emulator.
The following is printed in the console when I ran the code
[2010-11-21 10:51:12 - HelloAndroid] --
[2010-11-21 10:51:12 - HelloAndroid] Android Launch!

[2010-11-21 10:51:27 - HelloAndroid] Waiting for HOME
('android.process.acore') to be launched...
Could you please let me know is there any issue with the code or the
procedure? It would be really helpful if you point some good basic
references for developing Android apps..
TIA.

[android-developers] How to Dismiss a PopupWindow when Switching Among TabActivities?
Hi, I posted a StackOverflow question here (http://stackoverflow.com/ questions/4226898/dismiss-android-popupwindow-when-switching-to-a-new- tab-in-tabactivity/4227034#4227034) but it didn't get any responses. Basically, how can one dismiss a PopupWindow when changing to a different TabActivity? The onPause() method in my TabActivity causes the app to force close... Any help would be greatly appreciated! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Pubish: Target phones with fast hardware.
What i need is target hardware like Memory, CPU, and OpenGL 2. I read a comment on this article http://androinica.com/2010/05/12/dear-google-please-let-android-developers-target-their-apps-for-specific-devices/ I really like this comment: *The problem here is not (and should never be) fixed by blocking specific devices. If anything, because the list of devices will soon be too large for a single person to handle. * * It should be handled by requiring the correct hardware, if the Market doesn't already support that. Barcode Scanner, for example, could require auto-focus camera (there are already means for requiring a camera, for example; we just need a requirement for auto-focus). Raging Thunder 2 should ask for OpenGL ES 2, or a certain amount of VRAM, or whatever. * *tl;dr the Market needs many improvements, but blacklisting or whitelisting devices is a horrible solution. Check for hardware capabilities.*** * * Basically android already supports this partially with the uses-feature in the xml manifest. However there should be more support for the hardware types i mentioned. So: How should i do it now? And how is this going to be supported in the future? My only option now is to detect it on startup and give an alert box to the user that it doesnt work on their phone. However then my whole sale-model is ruined. 2010/11/20 DutchAndroidGuru dutchandroidg...@gmail.com I have an application that loads a 3dmodel and renders it. These models are rather big and i can only get it to work fast on faster hardware phones such as the Nexus One. However there is no way to target faster hardware phones. Now i get very good ratings (on phones where it work) and very bad rating (on slow phones). Also: i would like to know the phone type when a user comments. In this way i can test it and check whether the user had a valid point or not. Could you please add this? Same for error reports. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: SeekBar problem
Ok I've been able to obtain the slider update with this funny trick:
seekTime.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
public void onStopTrackingTouch(SeekBar seekBar)
{
final int progress = seekBar.getProgress();
seekBar.setMax(progress * 2);
*seekBar.setProgress(progress+1);*
* **seekBar.setProgress(progress-1);*
}
[...]
If i just do a setProgress(progress) it have no effect because it probably
recognize the same value and think that nothing is to update. I hope this
will help somebody in the future.

[android-developers] SharedPreferences are not stored
Hello everybody, This is my first question. I tried to ask in android-beginners, but the group is discontinued. My problem is using SharedPreferences. I just created a PreferenceScreen which holds inside a ListPreference with an array of 5 different values. Very simple! The array of values are different numbers: 1, 2, 5, 10 and 30. Every time I change the setting, the application remembers that and I can see the setting I chose when I access the preferences once again (as an user). Now, in the code, when I retrieve the setting using the key (e.g. getString(delay, default_delay);), I always get the default value, it seems that the SharedPreferences does not find my setting. Can anybody help? I have read about SharedPreferences.getEditor().commit(), but that should be used only when changing settings from the code, not from the UI preferences. Anyone had this problem before? P.S.- I use Froyo 2.2 to run the application (on a Samsung Galaxy S). --Claudio -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] IllegalStateException in MediaPlayer (Redux)
Hi folks,
Some time ago I posted an issue relating to an IllegalStateException
in the Media Player (http://groups.google.com/group/android-developers/
browse_thread/thread/46c7c2cd4f4a6958/5551d47aac93632c)
I have just launched the app into the wild and this error is
flooding in.
I just can't seem to fathom why.. here's the code:
if(mp != null) {
mp.stop();
mp.prepareAsync();
}
(mp is a MediaPlayer instance BTW).
According to the doco, prepareAsync is valid for {Initialized,
Stopped} states.. but I just can't see how it could be in any state
other than stopped??
The trace is:
java.lang.IllegalStateException
at android.media.MediaPlayer.prepareAsync(Native Method)
.. the line of code mentioned above follows.
Is it possible that stop() is not synchronous? Can't seem to see
anything in the doco stating this.
Anyone got any ideas?
P.S.
I'm seeing this on a wide range of devices, but all so far are version
2.1-update1

Re: [android-developers] Google Android Map Overlay
yeah i think SDK doesn't provide us to that functionality, so you must included other things like .XML which give us a layout resource, etc. On 11/21/10, Frank Weiss fewe...@gmail.com wrote: The Android SDK doesn't provide this functionality ready-to-go, but it can be easily implemented with a custom view class that extends FrameLayout, a controller class, a nine-patch image, and a layout resource (XML). You ought to be able to google for several solutions. Try the keyords mapview and balloon. IMO implementing it yourself is a valuable exercise that adds to your understanding of the Android SDK. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] SeekBar problem
Hello list.I would like to know why this code don't work:
seekTime.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
public void onStopTrackingTouch(SeekBar seekBar)
{
seekBar.setMax(seekBar.getProgress() * 2);
}
[...]
I'm sure that the function get called because i tried to set a breakpoint.
After the execution the mMax member value is correctly changed, the
mProgress don't change, but the graphical bar don't move as it should to
reflect the new value (it should go to the center).
I tried to add a
seekBar.invalidate();
but it don't help..

[android-developers] Android apps crashing on different phone models
Hi, I recently created a new feature in my apps that allows the user
to check if there is an update by getting an HTML page, looking
through it, and comparing the versions. However, this is causing the
application to force close on startup for many of my users using
Samsung and HTC phones, but works just as intended on droid x,
incredible, and 2. I can't get my hands on any of the phones that are
currently crashing and have no idea where to start in fixing it. I use
a AsyncTask to search, and start it using

[android-developers] Disabling a button until a set day
Here is the scenario: User opens app, they press a button and some activity launches. After the button is pressed and the activity is executed, I want to disable the button until the week starts over. Even if they close the app and come back, it should still be disabled unless it has reset. For example, if they press the button on Monday, they should not be able to do it again until Sunday at 12:00 AM. No matter what day they initially press the button, they should not be able to press again until the week starts over. What would be the simplest way to do this in android?

[android-developers] Pubish: Target phones with fast hardware.
I have an application that loads a 3dmodel and renders it. These models are rather big and i can only get it to work fast on faster hardware phones such as the Nexus One. However there is no way to target faster hardware phones. Now i get very good ratings (on phones where it work) and very bad rating (on slow phones). Also: i would like to know the phone type when a user comments. In this way i can test it and check whether the user had a valid point or not. Could you please add this?

[android-developers] best layout for app, dynamic set of 2 rows which consist of icons and text
Hello, I am developing simple web app, It gets data from url, then parses it with htmlcleaner + xpath. That was easy part. Now I am trying to present data and populate my RelativeLayout with data and icons(I store icons in local resources) I am trying to populate my Activity with multiple sets, every set consist of 2 rows: 1st row imageview(icon) - listview(text)-imageview(icon) 2nd row listview(text) 1st row imageview(icon) - listview(text)-imageview(icon) 2nd row listview(text) ... and so on the question is: am I going in the right direction? is there any other(simpler) way to accomplish what I need?

[android-developers] Unable to access all the pixel data of a Bitmap image from the native camera app
In short I have a bitmap image and need to access all the pixels to use the RGB for an image processing algorithm. When I use the dimensions from getHeight()/getWidth() in my for loops to cycle through the image and use getPixel(x,y) I get an out of bounds error and the app crashes. By trail and error I found that with an image of dimensions 480,320(from getWidth()/getHeight()), I could only access approximately the first 200,100 pixels. I set the methods to only get these pixels, do the processing and then use setPixel() to create a binary image. When I display this I get the bitmap with a square of processed pixels in the top left corner, the 200,100 pixels and the remainder is normal. The rest of the pixels are obviously there because I can display the image normally and the results of getting the dimensions is right but I am unable to access over half of the pixels. The bitmap data is from the native camera app, using an intent from my activity. The data is definitely a bitmap as I can do the usual methods to it, such as getWidth() etc. and can display it normally. I also tried this with a bitmap file in my res/drawable folder and the same thing happened. People I have spoken to have also had this problem and have simply given up making such apps. Is this a known bug and has any got any ideas as to a workaround. I have researched this online but not found anything.

[android-developers] Pubish: Target phones with fast hardware.
(seems like my previous post was not even posted, so this is a repost) I have an application that loads a 3dmodel and renders it. These models are rather big and i can only get it to work fast on faster hardware phones such as the Nexus One. However there is no way to target faster hardware phones.

In this way i can test it and check whether the user had a valid point or not. Could you please add this? Same for error reports. What i need is target hardware like Memory, CPU, and OpenGL 2. I read a comment on this article http://androinica.com/2010/05/12/dear-google-please-let-android-developers-target-their-apps-for-specific-devices/ I really like this comment: The problem here is not (and should never be) fixed by blocking specific devices. If anything, because the list of devices will soon be too large for a single person to handle. It should be handled by requiring the correct hardware, if the Market doesn't already support that. Barcode Scanner, for example, could require auto-focus camera (there are already means for requiring a camera, for example; we just need a requirement for auto-focus). Raging Thunder 2 should ask for OpenGL ES 2, or a certain amount of VRAM, or whatever. tl;dr the Market needs many improvements, but blacklisting or whitelisting devices is a horrible solution. Check for hardware capabilities. Basically android already supports this partially with the uses- feature in the xml manifest. However there should be more support for the hardware types i mentioned. So: How should i do it now? And how is this going to be supported in the future? My only option now is to detect it on startup and give an alert box to the user that it doesnt work on their phone. However then my whole sale-model is ruined. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Where are ldpi version of built-in icons
So does this imply that if the developer creates drawables of different densities via scaling and does not do different artwork or polishing after scaling in each density, one may as well put only the highest density (now 512x512) in the app and let android do the scaling? On Nov 21, 6:28 pm, Dianne Hackborn hack...@android.com wrote: The closest matching density is selected, and it is scaled appropriately to get an image for the actual density. This of course only works for images. (For other resource types, the closest matching density is picked... and then used without any change. Probably don't want to do that.) For anyone targeting 1.6 or later, I would suggest putting all bitmaps in one of the density qualified directories (drawable-ldpi, drawable-mdpi, drawable-hdpi, drawable-xhdpi, or drawable-nodpi), since it is important to know the density associated with the bitmap instead of treating it as raw pixels. For compatibility, a bitmap in a drawable directory (with no explicit density) is assumed to be mdpi. 2010/11/21 Kostya Vasilyev kmans...@gmail.com If you have none of the alternate versions for a drawable, then you don't have that drawable at all, agreed? So the only question is, is it only drawable that can be subject to automatic scaling, or does it work for e.g. drawable-hdpi to drawable-ldpi conversion.

[android-developers] 1.5 quits for apparently no reason whilst animating (WIN DEATH)
Hi,
I have an app that is working fine in 1.6 and up but crashing for
apparently no reason in 1.5. The app suddenly quits with the following
message...
I/WindowManager( 563): WIN DEATH: Window{43717218
com.bitbull.meat.android/com.bitbull.meat.android.MEATActivity
paused=false}
I/WindowManager( 563): WIN DEATH: Window{4373f458 SurfaceView
paused=false}
D/Zygote ( 541): Process 723 terminated by signal (11)
W/InputManagerService( 563): Got RemoteException sending
setActive(false) notification to pid 723 uid 10019
This error happens when the app is 'idling' (ie not doing anything
other than redrawing the screen). There is no state change and no user
input. The error occurs after the same amount of elapsed time whatever
I set the frame rate of the app to and occurs both on the emulator and
device. Changing what I display on screen can stop the error but there
appears to be no logic to this (in one instance not drawing a large
image stops the error but elsewhere just drawing some text causes the
app to crash in the same manner).
I am using SurfaceView for animations following the basic procedure in
the Lunar Lander sample app.
If anyone could help with this I would be *extremely* grateful as it
has me completely stumped at the moment.
best regards

Re: [android-developers] Re: guitar tuner
I just published a guitar tune app myself (Guitar FreaQ)...mostly for fun and to teach myself android development. I found that the FFT didn't use that much cpu at all (custom rendering did though) The fft algorithm computes N log(N) calculations. So if you do a 1024 point fft you are only doing 1024*10 calculations per pass. If you do a straight DFT computation per string and compare you will do 1024 calculations per string or 1024*6. For me, the additional 1024*4 calculations was worth the extra robustness.

Since you only have 6 (or 12?) strings to check, you could avoid the windowing by calculating a single point of the DFT of a length optimized for each string's frequency, normalizing, and comparing them to determine which is being played.

[android-developers] Re: make JPEG image has map
Im not sure of sample code for this, but here is how I would implement this. You dont necessarily need a map. An image view with a moving curses could be possible. You would set the location on the cursor in the image by using GPS location. You can receive lat and lon to your device. You would then convert those positions to X and Y respectively on your display. Then every time the location updates the cursor would move on your map.

[android-developers] 2.2.1 FRG83D: Existing map tiles are unnecessarily reloaded when panning, is it just me?
The Maps API always had its issues... since updating my Nexus One to 2.2.1 FRG83D earlier today, I see a problem more serious than anything prior. This applies to both Google Maps and (any) app that uses the Maps API (that I have tested). It's pretty obvious and simple, and cannot be remedied by rebooting the device: When panning the map view (no zooming that would trigger a complete re-load), map tiles that were already loaded, are cleared and reloaded. This can occur multiple times until the map view settles down. Looks pretty wild. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Android calls to web service slow? Using .NET web service
Well, my guess would be the long time can be attributed to the while loop
you have. That is probably where your code is getting stuck.
HttpResponse response = client.execute(request);
Try putting the log after this line, and see the times. If its still quite a
lot, then you have to worry.

Hey guys,
This is my first post to the Android Developers group. I have been
working with HTTP communication in the Android SDK and have noticed
that calls to a web service through my app are very slow (taking
800+ms on high speed wifi). They take less than 100ms if I call the
web service through the phone's browser. I am developing on a Google
Nexus One. The size of the data returned is very small, 1K. I have
tried enabling gzip compression, and that helps slightly but I assume
there is another problem at hand. I have tried using SOAP with the
ksoap2-android library, as well as making things simple using
HttpClient and InputStreamReader. Below is my code for the fastest I
can make the app perform; using no SOAP, and using GZIP compression. I
apologize for the lengthy code -- I think all of it is beneficial for
determining the best way to make this request and response happen
faster.
[code]
public String GetRest()
{
long startTime = System.currentTimeMillis();
String result = ;
Log.v(time, Beginning rest: + (System.currentTimeMillis() -
startTime) + ms);
try
{
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(https://usad.enlyght.com/ws/
AndroidService.asmx/GetWebServiceVersion);
request.addHeader(Accept-Encoding, gzip);
Log.v(time, Before call: + (System.currentTimeMillis()
-
startTime) + ms);
HttpResponse response = client.execute(request);
InputStream instream = response.getEntity().getContent();
Header contentEncoding = response.getFirstHeader(Content-
Encoding);
if (contentEncoding != null
contentEncoding.getValue().equalsIgnoreCase(gzip)) {
instream = new GZIPInputStream(instream);
}
InputStreamReader isreader = new
InputStreamReader(instream);
BufferedReader reader = new BufferedReader(isreader);
StringWriter sw = new StringWriter();
String read;
while ((read = reader.readLine()) != null) {
result += read;
}
client.getConnectionManager().shutdown();
}
catch (Exception e) {}
Log.v(time, End rest: + (System.currentTimeMillis() -
startTime) + ms);
return result;
}
[/code]

[android-developers] Re: Listview similar to call logs of 'contacts' app
Hi manas,
It is actually a single list view, where we don't press the call icon
when the parent is pressed.
Just add a onClickListener for your view (i.e., similar to call
button) in your ListActivity and implement the desired function in
that. And for eg. if you are using a ImageView, then just create a
class which extends ImageView and override setPressed function.
Eg:
@Override
public void setPressed(boolean pressed) {
// If the parent is pressed, do not set to pressed.
if (pressed ((View) getParent()).isPressed()) {
return;
}
super.setPressed(pressed);
}
So, this doen't press your image view, when the parent is pressed.
I hope this helps you.
Thanks,
Deepak

I forgot to mention 1 more thing. In the xml also, instead of

[android-developers] Re: is it faster to load a layout in java or xml
Seems like there are other things going on if it takes 2 seconds. On orientation change, you can save data in onSaveInstanceState() to be later retrieved in onCreate() which could possibly save some time. Not that I would advocate it but you could cache the layout so it doesn't need inflating again. The nice thing about using xml is not having to think too much about the layout. You can stick your portrait in /layout and landscape mode in /layout-land and the inflater will pick the right one. The support for a large variance of screen sizes, resolution, etc., makes using xml worth it.
