This seems wrong to me. No it doesn't do that. Would you have the Ant view open by any chance? Don't build from the ant view if you build using Eclipse. Hey Raph, To be clear, I'm not trying to build using ant from within eclipse. I use ant to do customised builds from the command line. All every-day builds are done from eclipse using F11-Debug As-Android Application. I simply want the two different build methods to ignore each other. I have a clean install of ganymede EE 3.4.2, the latest DDMS, no ant views open, and a cleaned android project. If I rename build.xml to build.txt and refresh the project, the error goes away, and I can launch and debug the project. If I rename it back to build.xml and refresh the project, the errors aren't detected, and I can launch and debug If I open build.xml with the ant editor (because I want to edit it :), the error is detected, and I can no longer launch and debug, even if I close everything and refresh. If I open build.xml with the xml editor, the error is not detected...so I guess I just found my own work-around. Never open the ant editor.

[android-developers] Re: implementation of onDestroy for a service containing a worker or backround thread
Android may kill the process and thus the service running in the process, once onDestroy() returns (after sending a message to the worker thread). But how will I make sure that the service has completed it's clean up operations (ex. saving some data on to some storage, etc...), if any? The main thread nevers gets blocked in any other scenario except onDestroy(). Do you have any other mechanism to achieve this behavior in the platform?

Now, when onDestroy() is called, I want to send a message to my service thread to do the necessary cleanup. Only when the service thread acknowledges that the cleanup or shutdown is complete, onDestroy () should return. I could find a way to send asynchronous messages to threads and the corresponding processing of the messages, but not able to figure out how I need to implement onDestroy(), such that it would send a message to the service thread and should wait for a result, before returning.

[android-developers] Using Parcelable with Android 1.5
Hello,
I have a small problem, hope you can help me.
I want to pass one object of class A from one Android Activity to
another and I need to use Parcelable (performance and Class loading
issues). My code is similar to the lines listed below:
class A implements Parcelable {
private String x; //other fields here...
private B b;
..
public void writeToParcel(Parcel out, int i) {
out.writeString(x);
out.writeParcelable(b, i);
}
public static Parcelable.Creator CREATOR = new Parcelable.Creator
() {
public A createFromParcel(Parcel in) {
A result = new A();
result.x= in.readString();
result.b = in.readParcelable(getClass().getClassLOader
());
return result;
}
}
}
class B implements Parcelable {...}
// Sending Parcelable
bundle.putParcelable(KEY1, a);
bundle.putSerializable(KEY2, something);
bundle.putParcelable(KEY3, otherParcelableObject);
//Receiving Parcelable...
@Override
public void onCreate(Bundle icicle) {
Bundle receivedBundle = getIntent().getExtras()
Object o= receivedBundle.getParcelable(KEY3)
// Problem: o is NULL here
// Debug: receivedBundle.mMap= HashMap{ [something, null],
[Map { [KEY3, other], [null,null] }, KEY2], [KEY1, a] }
If I remove from class A the code that writes B into Parcel,
receivedBundle.mMap has the expected value: HashMap {[KEY1, a], [KEY2,
something], [KEY3, other]}.
Am I doing something wrong or is the parcelization mechanism not
supporting recursive Parcelable entities?
Thanks in advance,
Lia.

See http://code.google.com/p/android/issues/detail?id=823 Android 1.5 still lacks support for decoding preview images, while data [] is headerless.

[android-developers] Re: Controlling the width of listview items
Thanks Romain, although I'd be interested in any tips on how to get around that? Would I have to implement my own custom ListView sub- class, or where should I start? What I also don't quite understand is why I get the same result even if I embed a second inner RelativeLayout inside the outer one and set wrap_content on that one as well. Even if it only encloses those two small TextViews (for which wrap_content does work) it still grows to fill the parent. It's as if wrap_content is overruled by the ListView for _all_ ViewGroups found in the entire hierarchy of the list item? What am I missing here?

[android-developers] Re: How to let Android create my activity within the process which the launcher activity lies in?
Thank your very much!
BlablaManager actually handles the image editing session information.
One task shall have only one session.
I understand your point. Now I quit using singleton stead using a
static field of the main activity to reference the instance of
BlablaManager, and then any other activities within my application
share the instance with this static field.
Currently it works fine. But I don't know whether it's OK as design in
Android.
Please give your comments.
Thanks!

Because you have set up your app to behave this way.
But
they are all created within one Dalvik VM linux process, and Dalvik VM
didn't distinguishes the static field(mInstance) which reference the
singleton class instance for two activity instances belongs to two
different tasks. Then I encounter the problem.
Yes, all instances of a particular activity run in a single process. This
for the most part a feature, and there are actually a lot of things that use
singletons to take advantage of this.
So I think the problem occurs because Android define a Task can be
cross process, but Dalvik VM still handles static field based on
process. So do you think this is a little confused?
It is working exactly as intended, which is fine.
Because if we
think Activity as a module in a Task, for other OS, normally a Task is
a single process, and that process can have modules(dynamic link
library). Static variable can also be defined in dynamic link library,
but that static variable will be map in the process which load the
library. That static variable won't be shared to different processes
(Tasks).
I would suggest not thinking of Android tasks in any way like what you think
tasks are on other platforms. The -only- thing a task is on Android is a
way to organize related activities.
My singleton class is implemented like this:
BlablaManager
{
public static BlablaManager getInstance()
{
if (mInstance == null)
{
mInstance = new BlablaManager ();
}
return mInstance;
}
private BlablaManager()
{
}
private static BlablaManager mInstance = null;
}
That's fine, and you get to share one instance of this with all things
running in a process.
Matt suggested to use the Application context to synchronize access to
the singleton. But I still not very clear about how to implement.
Should I add a context parameter to getInstance() and maintain a list
of application context reference, so I can return different instance
of BlablaManager for different application context?
Honestly, I think at this point you should stop doing whatever you are doing
which is causing your activity to be used in multiple different tasks,
because this sounds like it isn't the behavior you want. But you haven't
really clearly described how you are currently setting up your activity
flow, nor exactly how you want it to work, so it is hard to provide more
help here.
And if you really do want your activity to be in separate tasks, then you do
indeed need multiple instances of it, and it sounds like whatever this
BlablaManager thing is should just not be a singleton.

Try LISTEN_CALL_STATE. LISTEN_SERVICE_STATE is whether or not you have a

[android-developers] Re: Help for decoding the camera data from the PreviewCallback

[android-developers] Re: What is the difference between thread and service?
From what I under understand, your application having a service running is basically just holding a (service) object that tells Android not to kill your process. The service onStart methods etc. still run in your main thread and are subject to Application not responding. You could have a thread directly in your activity without using a service, but Android might kill your Activity/process when you're not looking.

[android-developers] Maximum size of onSaveInstanceState bundle
I have an activity that loads a bitmap from a database when it starts up. Due to the nature of the app, should the activity be killed and recreated at a later point, I cannot guarantee that the bitmap in the database is still the same one. Should I save the bitmap to the bundle to be able to ensure I am still having the same data available when my activity is restored? The bitmap may be multiple 100 kilobytes in size, and I worry that saving data this large would defeat the whole purpose of having my activity killed by Android in the first place.

[android-developers] Re: Service stops running in standby mode
The problem here is, imho, that cell location changes cannot be
detected with a broadcast receiver, but instead we have to use a
listener. A broadcast receiver would just be activated/started when
the cell location has changed.
The listener though has to run all the time to be able to listen. As
far as I understand, there is no other way as to use a permanent wake
lock to listen to cell changes.
I use the boot completed broadcast receiver to start my listener.
Otherwise I would have to start the app/listener manually after each
boot.
This is the code I use for getting the wake lock:
final PowerManager pm = (PowerManager) context.getSystemService
(Context.POWER_SERVICE);
wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, TAG);
wakeLock.acquire();
I use PARTIAL_WAKE_LOCK because I want the screen to go off, though
the cpu should keep processing my listener.
The problem might be, that I have no context object withing the
listener. So I pass the context object from the boot completed
receiver to my listener. Could this be the problem?
br and thanx for your help, ash

Correct.
The PhoneStateListener gets loaded on boot time
public class CellStateListener extends PhoneStateListener {
public void onCellLocationChanged(CellLocation location) {
...
//this is the logging service which is informed when the cell
location changes
listener.onCellChanged(mcc, mnc, lac, cid);
...
}
}
If you are doing this from a BroadcastReceiver, that is fairly evil.
I tried to use the PowerManager to set a PARTIAL_WAKE_LOCK in my
logging service. But this doesn't work.
You may be using the WakeLock incorrectly, then. My guess, from your
symptoms, is that the device is falling asleep, which is why you are not
detecting new cell location updates.
Bear in mind, though, that permanently holding a WakeLock, so you can
find out about cell location updates, will mean the CPU never stops, and
your users will be inclined to beat you about the head with a tire iron
due to the vastly reduced battery life.

[android-developers] Re: Decrypt in Android using RSA
A bad padding exception usually means your data has been corrupted in transit. If you're doing using an intermediate format (e.g. a hex string) you'll need to make sure your decoding gives the same result as the originally encoded string.

[android-developers] Re: implementation of onDestroy for a service containing a worker or backround thread
Can I use the thread.join() mechanism? Basically, in the onDestroy() method of the service, I would send a message to the background thread and call join on the thread. The background thread would destroy it self after proper cleanup. But, what method should I use to exit the thread. Please note the background thread uses a looper to handle messages from the main thread. Or, pl. suggest some other method of implementing the above behavior. On May 27, 11:31 am, gautam_raychaudh...@hotmail.com wrote: Android may kill the process and thus the service running in the process, onceonDestroy() returns (after sending a message to the worker thread). But how will I make sure that the service has completed it's clean up operations (ex. saving some data on to some storage, etc...), if any? The main thread nevers gets blocked in any other scenario exceptonDestroy(). Do you have any other mechanism to achieve this behavior in the platform?

According to the Android document, when the OS plans to free some system resource, it will callonDestroy () on the service and only whenonDestroy() returns it will kill the process hosting the service, thus giving opportunity to the service to cleanup. Now, whenonDestroy() is called, I want to send a message to my service thread to do the necessary cleanup. Only when the service thread acknowledges that the cleanup or shutdown is complete,onDestroy () should return. I could find a way to send asynchronous messages to threads and the corresponding processing of the messages, but not able to figure out how I need to implementonDestroy(), such that it would send a message to the service thread and should wait for a result, before returning.

[android-developers] Re: EMMA Code coverage and JUnit
Hi Deeps, Nice to hear that you are making progress. Are you using only the SDK, or are you building the entire android source code? Maybe your code is not instrumented to generate the coverage statistics and this would be why you are getting 0% of code coverage. Are you using the emma.jar provided on the Emma site, or the one built in Android source code?? I'll try to reproduce what you have done up to now here. I hope we can manage to get a final solution for this matter.

Hi all,
I got errors when I install the plugin, sometime.
I build a system image from the source code and copy the system.img to
androidsdk1.5/platforms/android-1.5/images/. When I build the sample IM
plugin and install it. Sometime I got error:
package com.android.im.plugin.demo has no signatures that match those in

It seems that the demo plugin use same user id as the IM.apk in system

add the signature to demo plugin?

[android-developers] SDK 1.5 CPU usage
Since installing the 1.5 SDK, I have noticed a significant slowdown in my computer when I have the emulator running. I left the emulator running when I went to bed last night, and this morning brought home the reason why : In task Manager, when I sorted by CPU Times the top five were the following: Emulator 7:25:30 System Idle Process 2:55:49 Eclipse 2:08:07 Iexplore 0:46:13 System 0:11:44 FYI, I'm running XP Pro with 4 gig's of RAM, so memory shouldn't have anything to do with it. I'm not really complaining. If that is normal, I'll live with it, but I don't remember ever seeing an application use more CPU time than the System Idle Process (unless it was about to crash :-)). Is there some setting I can change that would help this?

convertView.findViewById(android.R.id.text1);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
//holder.checkbox.setChecked(true);
String mvalue = ((Item)lv.get(position)).getValue();
holder.checkbox.setText(mvalue);
if(mSelectedValues != null mSelectedValues.length 0) {
boolean blnSetChecked = false;
for(String s : mSelectedValues) {
if(s.equalsIgnoreCase(mvalue)) {
blnSetChecked = true;
break;
}
}
holder.checkbox.setChecked(blnSetChecked);
} else

[android-developers] Re: adb push wtf
Hey all,
in case anyone else has a similar problem - here is a bit of code that
might help. All I do is write a dummy file to the location I want to
put a file to, making it world writable (not sure if I have to sue
this flag or not, but it does not matter really, as i will only use
this script once), then push right on top of it
public class Playback extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
FileOutputStream fs = openFileOutput(ff.mp4,
Context.MODE_WORLD_WRITEABLE);
fs.close();
} catch (FileNotFoundException e2) {
e2.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Run that to create the correct folders and files
(org.you.yourapp.whatever/files/yourfile.woohoo), then push
squid$ adb -d push ~/Desktop/ff.mp4 /data/data/org.test/files/ff.mp4
failed to copy '/Users/squid/Desktop/ff.mp4' to '/data/data/org.test/
files/ff.mp4': Permission denied
squid$ adb -d push ~/Desktop/ff.mp4 /data/data/org.test/files/ff.mp4

Then you can't push it there. Your application will need to do something
to cause that folder to be created (e.g., call openFileOutput() from
your application).
Thank you~ I got it solved.

[android-developers] Re: implementation of onDestroy for a service containing a worker or backround thread
Send a message to your background thread telling it to end.
Your background thread:

private boolean _isRunning = true;
public void run() {
...
...
while (running()) {
... // fetch and handle messages. ...
}
}
..
private synchronized running() {

}
public synchronized stopThread() {
_isRunning = false;
}
...

Basically, in the onDestroy() method of the service, I would send a

The background thread would destroy it self after proper cleanup. But,
what method should I use to exit the thread.
Please note the background thread uses a looper to handle messages
from the main thread.
Or, pl. suggest some other method of implementing the above behavior.

But how will I make sure that the service has completed it's clean up

The main thread nevers gets blocked in any other scenario exceptonDestroy().
Do you have any other mechanism to achieve this behavior in the
platform?

Hi,
I'm implementing a service that contains a thread to handle all
time consuming operation. My core service logic is in a different
thread than the ui or main thread. According to the Android document,
when the OS plans to free some system resource, it will callonDestroy
() on the service and only whenonDestroy() returns it will kill the
process hosting the service, thus giving opportunity to the service to
cleanup.
Now, whenonDestroy() is called, I want to send a message to my
service thread to do the necessary cleanup. Only when the service
thread acknowledges that the cleanup or shutdown is complete,onDestroy
() should return.
I could find a way to send asynchronous messages to threads and the
corresponding processing of the messages, but not able to figure out
how I need to implementonDestroy(), such that it would send a message
to the service thread and should wait for a result, before returning.
Appreciate if someone can comment on my understanding ofonDestroy
() and provide some solution to the above problem.
Thanks and Regards,
Gautam.

[android-developers] flagNoExtractUi still showing keyboard text area
I'm probably doing something wrong here, but when I set flagNoExtractUi on an EditText the onscreen keyboard still shows its text input area when I type on it (this is in the 1.5 emulator, building against 1.5). How do I get the text area not to display? Here's the xml, and it's the same if I set the option programmatically: EditText android:id=@+id/search android:layout_width=0dip android:layout_height=wrap_content android:layout_weight=1 android:layout_gravity=center_vertical android:layout_marginLeft=6px android:paddingLeft=3px android:textSize=14sp android:textStyle=normal android:textColor=@drawable/text_entry android:background=@drawable/background_text_entry android:singleLine=true android:imeOptions=actionDone|flagNoExtractUi / Thank for any help. -- Peter --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: UnknownHostException on 1.5 emulator
Thanks for the quick response David. I've only seen this on the 1.5 emulator running from the 1.5 SDK, I haven't tried the 1.1 emulator. Previously I was running the 1.0 SDK and never saw it. Below is the / system/build.prop from the emulator, let me know if you need anything else. It happens on all apps that I've tried, I noticed it first in our app then tried the browser, which is what I took the trace from (opening www.google.com). Our app is doing a java.net.HttpURLConnection.connect () when it fails, not sure if the browser uses that too. I haven't been able to reproduce it so far when running with -tcpdump, but I'll let you know if I do. -- Peter -- ro.build.id=CUPCAKE ro.build.display.id=sdk-eng 1.5 CUPCAKE 147336 test-keys ro.build.version.incremental=147336 ro.build.version.sdk=3 ro.build.version.release=1.5 ro.build.date=Tue Apr 21 21:10:23 PDT 2009 ro.build.date.utc=1240373423 ro.build.type=eng ro.build.user=android-build ro.build.host=undroid16.mtv.corp.google.com ro.build.tags=test-keys ro.product.model=sdk ro.product.brand=generic ro.product.name=sdk ro.product.device=generic ro.product.board= ro.product.manufacturer=unknown ro.product.locale.language=en ro.product.locale.region=US ro.board.platform= # ro.build.product is obsolete; use ro.product.device ro.build.product=generic # Do not try to parse ro.build.description or .fingerprint ro.build.description=sdk-eng 1.5 CUPCAKE 147336 test-keys ro.build.fingerprint=generic/sdk/generic/:1.5/CUPCAKE/147336:eng/test- keys # end build properties # # system.prop for generic sdk # rild.libpath=/system/lib/libreference-ril.so rild.libargs=-d /dev/ttyS0 # # ADDITIONAL_BUILD_PROPERTIES # ro.config.notification_sound=F1_New_SMS.ogg ro.kernel.android.checkjni=1 xmpp.auto-presence=true ro.config.nocheckin=yes net.bt.name=Android dalvik.vm.stack-trace-file=/data/anr/traces.txt --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Can only hear sound when playing video
Which Audio and Video dev guide are you referring to? If that guide tells
you that the code you posted should work, it needs to be fixed :)
There are several problems in your code, but the main one is that you can't
use any of the MediaPlayer.create() convenience methods to play video from a
resource. This is because create() calls prepare() internally, but you need
to call setDisplay() before calling prepare().
You'll need to use new MediaPlayer and setDataSource and setDisplay
instead. Also be sure to wait for the surfaceCreated callback on the
SurfaceHolder before calling start().

[android-developers] Re: Can only hear sound when playing video
Marco,
Thank you so much! I just spent a day and a half trying every example
I could get my hands on, and about 2 minutes before you replied I
found a hint that video could not be a raw resource. I had just been
adapting every example to include that, and it never occurred to me
that might be the problem!
The dev guide I reference is here
http://developer.android.com/guide/topics/media/index.html
It is very lacking on video info in general, but in particular it
never mentions that video cannot be a raw resource, and I never found
that on Google's site anywhere! I would like to file a issue, but
before I do, do you know if they include it elsewhere? I don't want to
turn in an issue that says it is never mentioned, and then have them
dismiss it because it was mentioned somewhere I didn't look.
Thanks again, I am so relieved to be done with that!

[android-developers] Re: using stl in Android
Second, as I understand it, Android is mostly in C, not C++, though I may be wrong about that. I'm not sure what your point is in the above statement. Just because a system is built using one language, does not mean other apps cannot be developed using some other language. As long as there is a C++ compiler for the processor, then coding in C++ should not be an issue and neither should using the STL. BTW, there is an ARM C++ compiler which will work just fine if you want to develop native C++ applications. Of course, as Mark mentioned, Android apps are currently written in Java, although that may change in the future (at least here's to hoping). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: ant and eclipse builds don't play nice
That's kind of an unexpected workflow. The idea is that either you go the full way in Eclipse or you use Ant/DDMS. Trying to combine both is a recipe for confusion :-) What you can try: - use Ant to compile - use the ant install or reinstall target to push the apk - launch app manually - you can still debug by manually selecting the app in Eclipse DDMS perspective and applying the debug icon on it. - make sure you have automatic build disabled in Eclipse If you don't want to launch the app manually you can make an ant target by using the adb shell am start launch command. It goes something like this (from memory): $ adb shell am start -D com.blah.myapp/com.blah.myapp.MyMainActivity (run am without args to see the help) HTH R/ On Tue, May 26, 2009 at 11:02 PM, Craig supkic...@gmail.com wrote: On Wed, May 27, 2009 at 2:36 PM, Raphael r...@android.com wrote: On Tue, May 26, 2009 at 6:26 PM, Craig supkic...@gmail.com wrote: On May 26, 9:49 pm, Zero zeroo...@googlemail.com wrote: from my experience, eclipse never used the build.xml for it's internal builds - how did you do that ? The eclipse build doesn't use build.xml at all, but due to the fact that build.xml is in the eclipse project (because it is in the same directory as AndroidManifest.xml) eclipse tries to build it or at least parse it and check for errors. build.xml can't be parsed by eclipse (even though it is a valid file according to ant) and thus the android builder refuses to launch the project at all. This seems wrong to me. No it doesn't do that. Would you have the Ant view open by any chance? Don't build from the ant view if you build using Eclipse. Hey Raph, To be clear, I'm not trying to build using ant from within eclipse. I use ant to do customised builds from the command line. All every-day builds are done from eclipse using F11-Debug As-Android Application. I simply want the two different build methods to ignore each other. I have a clean install of ganymede EE 3.4.2, the latest DDMS, no ant views open, and a cleaned android project. If I rename build.xml to build.txt and refresh the project, the error goes away, and I can launch and debug the project. If I rename it back to build.xml and refresh the project, the errors aren't detected, and I can launch and debug If I open build.xml with the ant editor (because I want to edit it :), the error is detected, and I can no longer launch and debug, even if I close everything and refresh. If I open build.xml with the xml editor, the error is not detected...so I guess I just found my own work-around. Never open the ant editor.

[android-developers] What's the best way to handle an task w/progress dialog on orientation change?
I have an app that communicates with a server. While it is communicating, it shows a progress dialog. The way this actually works is that I have a class that I call my NetworkGateway. Each method takes a Handler as a callback so that the gateway can send back the response as a bundle when it has finished. Right now when someone changes orientation while a network operation is occuring, the activity doesn't know that a thread is running the network code and then the callback might be invalid. What's the right way to do this? I want to make it so that after the orientation switch, the activity can check something to see if a network operation is running and if so, display the progress dialog again and wait for the callback, or set itself as the callback handler now, invalidating the old one. My first guess is that this is exactly the kind of thing services were designed for, but I'd like specifics if anyone can supply them.

My bad, that method does not exist. You'll need to get an AssetFileDescriptor for your resource, and then use setDataSource(FileDescriptor, long, long) with the FileDescriptor, offset and length from that AssetFileDescriptor. I was wondering. I had never heard that before, and I did read that state description. If I missed it I figure others might be making the same mistake. Yes, this exact issue has come up in the past on this list. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Cannot allocate any memory when using camera pic
I have an app that displays a camera picture as part of it, but if the picture is in memory I get an out of memory exception when an allocation of any size happens no matter what. If the app uses a seekbar in addition to my PictureView the ~900 bytes it allocates are too much. I even tried to load a 16x16 monochrome image on top of the camera pic, but the 256 bytes were too much. I find it extremely unlikely that the object containing the image is precisely the size so that using it alone never causes a crash, but allocating even 256 more bytes exceeds the memory budget. Does anybody know what the problem is? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] ActivityGroup + embedded Activity search window
Hi all, I have an ActivityGroup with an embedded TabActivity and another simple Activity. The TabActivity has three tabs, each one with a ListActivity. When I try to start a search from a list (calling onSearchRequested()), I get a WindowManager$BadTokenException. I've tried requesting focus in the list, but the same error occurred. What should I do to solve this? Taísa --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Cannot allocate any memory when using camera pic
I have a temporary workaround, but I'd still like to get this issue solved. As for the workaround, it seems that if the SeekBar's image is loaded before the camera picture, the memory error doesn't occur. Right now I have a boolean flag so that the first time my derived ImageView's onDraw method gets called it sets the image, rather than setting it in the xml layout. After this it trips the flag and subsequent onDraw calls get passed to the super. It's not ideal, but it works On May 27, 2:30 pm, Max Salley msalley@gmail.com wrote: I have an app that displays a camera picture as part of it, but if the picture is in memory I get an out of memory exception when an allocation of any size happens no matter what.

[android-developers] Re: Cannot allocate any memory when using camera pic
I'm not sure about the exact point of failure, which - indeed - seems very precisely cut against the memory needed to load exactly one camera pic. However, you can avoid this. Don't load the full size pic. Load the bitmap using the BitmapFactory and set the Config's inSampleSize attribute to a value larger than 1 (2, 4, 8, 16) that would fit the pixel-size of your PictureView. E.g. use 4 to get a 512 x 384 bitmap that can snuggly fit (without being up-scaled) into a 480x320 size PictureView. If your PictureView is smaller, set the 'inSampleSize' to a larger value.

[android-developers] Re: What's the best way to handle an task w/progress dialog on orientation change?
I just looked at it. 1) They state that it is only an optimization and that you are not to rely on the method being called. 2) My design is a little too complex to use that elegantly. I do network calls from multiple activities and some dialogs on those activities, which need to chain to other actions upon completion. I'm learning about Services right now and I think that if I could have a network service that I can register a specific callback with, like a User Updated callback, it would work really well. When the service finishes updating a user, it simply notifies the user updated callback. It won't care if it was the original activity/dialog or a new one. Does that sound feasible?

[android-developers] Re: What's the best way to handle an task w/progress dialog on orientation change?
I agree you should use a service. But for optimization, i would use this method. You should have a call to the service to query if the service is still busy. If so, show a progress dialog and start listening to the service to know when it no longer is busy (callback from the service into your app) On May 27, 4:07 pm, Robert Green rbgrn@gmail.com wrote: I just looked at it. 1) They state that it is only an optimization and that you are not to rely on the method being called. 2) My design is a little too complex to use that elegantly.
