Hello Blake,

Thank you for your reply! I really appreciate it.
It looks like I didn't give enough details on my problem, so here is some 
more information. As I already mentioned, we have the following inheritance 
chain:

CustomListView - ListView - AbsListView - AdapterViewT - ViewGroup - 
 ...


In my CustomListView class I've overrode protected void layoutChildren() 
{...}. From that overridden method I'm calling super.layoutChildren(). 
After that there is a chain of internal calls within ListView class:

layoutChildren() - fillFromTop() - fillDown() - makeAndAddView() - 
 obtainView()


obtainView() method is defined in AbsListView class and has a default 
access modifier, thus I have NO ability to override it, as my 
CustomListView class belongs to the different package. As a result, I can 
only hide it, if I'll define obtainView() method with the same signature. 
The thing is that my method SHOULD NOT be called from makeAndAddView() 
method of the ListView class, obtainView() which belongs to the AbsListView 
class should be utilized instead. But my tests show that obtainView() from 
my CustomListView class is called, which is not correct. If I do not define 
obtainView(), call chain looks as follows:

... - makeAndAddView() - obtainView() - setupChild() - 
 attachViewToParent() OR addViewInLayout()


Both attachViewToParent() and addViewInLayout() are defined in the 
ViewGroup class and have protected access modifiers, thus I SHOULD have 
an ability to override them. BUT if I define this methods in my 
CustomListView class, attachViewToParent() or addViewInLayout() of the 
ViewGroup class are called instead, which is also incorrect.

Here are the sources of:

ListView.java - 
http://grepcode.com/file_/repository.grepcode.com/java/ext/com.google.android/android/4.0.3_r1/android/widget/ListView.java/?v=source
AbsListView.java - 
http://grepcode.com/file_/repository.grepcode.com/java/ext/com.google.android/android/4.0.3_r1/android/widget/AbsListView.java/?v=source
ViewGroup.java - 
http://grepcode.com/file_/repository.grepcode.com/java/ext/com.google.android/android/4.0.3_r1/android/view/ViewGroup.java/?v=source

I would really appreciate the insight of such guru as you. Thank you again 
for you time!

Have a nice day!
Alex

Re: [android-developers] Showing a confirm dialog from the PreferenceAcivity

2012-07-05 Thread Kostya Vasilyev

DialogPreference, and Dialogs in general, work just fine on Android 3.* and
4.*

And if you're asking about the compat library, AFAIK, ActionBarSherlock has
a PreferenceActivity reimplementation that is compatible with the compat
library's fragments.

 Thank you for your reply.
 However, this does not answer the main problem, which is - how to show a
 dialogfragment from a PreferenceActivity, which is not a fragment based
 activity !

Re: [android-developers] Adding build versions

2012-07-05 Thread Kostya Vasilyev

I wanted the same, and so made a few changes to Android's ant build scripts
to extract the version name from the manifest and append it as a suffix to
the apk name.

( along with some other stuff, like Market vs. non-Market, which use
slightlity different code for updating and licensing, and are released at
the same time )

My changes also move all ant related intermediate and output files in a
separate subdirectory, so they don't interfere with Eclipse.

The Android build script is pretty easily to follow and to modify, while
Ant docs are available on its web site.

-- K

2012/7/5 Damien Cooke cooke.dam...@gmail.com

 All,
 I usually build my apps and compile in a build version.

 I have found no way of doing this for my android apps.

 I can add an ant task. But this makes the eclipse tools a little clumsy.

 Is anyone else doing this or have done this and would like to share the
 experience?

 Regards
 Damien.

[android-developers] How to set up android emulator for live face detection?

2012-07-05 Thread Viktor Brešan

 

I have an emulator running 4.1 Android. Virtual device is set up so that it 
has camera emulated by the web cam. This part works fine.

However Camera.Parameters.getMaxNumDetectedFaces() always returns 0, 
meaning that face detection is not supported (though it works fine on 
static images).

Is there anything that can be done in order to enable live face detection 
on Android emulator? I am talking about the face detection that came with 
API level 14, not third party libraries.

Thanks, Viktor.

Re: [android-developers] TransactionTooLargeException exception calling queryIntentActivities()

 Thanks, I'll try the GET_* flags -- there are quite a few bits of

Yeah, once you get below 1MB, the exception should go away.

:-)

Beyond that, I am not aware of other measurement options, sorry.

 Basically, TransactionTooLargeException means you're trying to
 retrieve  1MB (IIRC) from a foreign process. In this case, the user
 has too many apps installed, presumably.

 This is why I think Google needs to do the underlying work in batches or
 otherwise overcome the 1M limitation. This is happening on regular user
 devices.

File an enhancement request at http://b.android.com and hope for the best.

[android-developers] Re: TransactionTooLargeException exception calling queryIntentActivities()

2012-07-05 Thread RichardC

Have you looked at the Launcher source code for the various platform

 Part of my applications duties are to enumerate launcher activities --

 I saw a related post about 
 getInstalledPackages()https://groups.google.com/forum/?fromgroups#!topic/android-developers/EK4eJPadabsbut
  it seemed to end with Don't do that which seems like an odd answer to 
 just using the API. I'd expect that in this case if the underlying 
 implementation is limited to 1M that the query is done in batches and 
 hidden from the developer or that an API exists to do it in batches myself.

 Any ideas? This works nearly all of the time (expected!) but it seems that 
 every now and then I'm running into this exception in the wild on customer 
 devices.

Re: [android-developers] Android Carousel

2012-07-05 Thread Jorge Gil Royo

Problem solved.

What happened was that I did not realize the resolution of the mobile screen,
then the carousel buttons appear, but were covered by other layouts.

Once adjusted the size and position of the buttons of the carousel, the
buttons are displayed correctly.

Thanks for the help!

2012/7/4 Jorge Gil Royo jorgeg...@gmail.com

 Using the emulator 4.x working properly.

 When I use the phone there is no message in the logcat containing
 information about the carousel.

 Is the first time something happens to me so strange.

 Thank you!


 2012/7/4 Jorge Gil Royo jorgeg...@gmail.com

 Usando el emulador 4.x funciona correctamente.

 Cuando uso el teléfono móvil no aparece ningún mensaje en el LogCat que
 contenga información acerca del carrusel.

 Es la primera vez que me sucede algo tan raro.

 And if you test on the 4.X emulator?

 Your question is extremely vague. How about some screenshots? Anything
 in the LogCat that looks useful?

Yes, because it is emulating an arm processor.  Use one of the x86
emulation solutions that can benefit from virtualization (vs
emulation) instead.

Using a device is highly recommended though; the major reason not to
use one is when you need to test on an android version you don't have

[android-developers] Jelly Bean errors with LVL

2012-07-05 Thread H

Hi, been seeing some ACRA reports from users on Jelly Bean when my app runs 
the LVL code.

In the LicenseValidator.verify() method, I perform this twice:

sig.verify(Base64.decode(signature))

I do it once to check it returns true, and then I call it again to confirm 
it is still true (this gets around an anti-lvl check which forces the first 
check to be a hard coded true but isn't aware of the second check). But 
it appears the second check is now failing on Jelly Bean:

Caused by: java.security.SignatureException: java.lang.NullPointerException
at 
org.apache.harmony.xnet.provider.jsse.OpenSSLSignature.engineVerify(OpenSSLSignature.java:244)
at java.security.Signature.verify(Signature.java:375)
at com.android.vending.licensing.c.a(SourceFile:135) -SECOND 
sig.verify(..) call.

Method)
at 
org.apache.harmony.xnet.provider.jsse.OpenSSLSignature.engineVerify(OpenSSLSignature.java:240)
... 7 more 

Does anyone know if the implementation of Signature or the underlying 
classes has changed..? I'm guessing that since the first check works and 
the second fails, can you now only perform one verify() on a signature and 
after that, the object is no longer valid to be verified again()..?

Yes, it has changed. In JB, the OpenSSL based provider has been
extended to support RSA
keys and RSA signatures (SHA1withRSA, etc.). Additionally, this is now
the default, so the
signature verification code that previously was using the Java crypto
provider (BouncyCastle)
is now calling the native one (Cf. NativeCrypto.EVP_VerifyFinal --
that's a wrapper for an
OpenSSL function). This has presumably done for better performance,
but there seem to be
a few bugs, I've been getting crashes here and there too. Changing

Signature.getInstance(SHA1withRSA) to
Signature.getInstance(SHA1withRSA, BC)

should make it work as before, but do some testing to be sure.

Cheers Nikolay - thanks for the quick update, I'll try your suggestion and
see if that cures it.

Do you know if this has been reported on b.android.com - I've been checking
it as normal but not noticed anything that sounds similar to this..?

I presume bouncycastle implementation might go completely in a later
release of Android..?

[ But I haven't downloaded the Jelly Bean image yet as I need to upgrade
adt and that is always a major headache - I might just have to mail an
updated version to some users and ask them to check it works for me. ]

 Do you know if this has been reported on b.android.com - I've been checking

I don't know, haven't checked, but probably not. If you can come up with a
simple test case that reproduces this reliably, do report it. (calling verify
two/multiple times in a row with the same Signature instance?)


 I presume bouncycastle implementation might go completely in a later release
 of Android..?

Probably not, but don't take my word for it. OpenSSL is not without
its flaws and
re-implementing everything on top of it is a pain.


 [ But I haven't downloaded the Jelly Bean image yet as I need to upgrade adt

If you don't want to change your dev environment, simply create a new Eclipse
installation, and use that for testing ADT 20, JB, etc.

[android-developers] Re: Adding custom enum states to an ImageButton

2012-07-05 Thread li lianyu

It's seems that currently Android doesn't support non-boolean state. You 
can verify it by adding another item with non-a state in selector pair. I 
assume Android evaluates true/false only by checking whether corresonding 
state attribute be in drawableState returned by onCreateDrawableState.

On Saturday, January 21, 2012 3:40:41 AM UTC+8, Nick wrote:

 I have searched around and I found good examples on adding custom 
 boolean states to a drawable but I am having issues adding a state 
 that is a list of enums.  I am sure most of my problems lie within the 
 onCreateDrawableState call so I have a few questions. 

 1) Is the extraSpace param to onCreateDrawableState the number of 
 additional int[] that I would like to add or the size of the int[]? So 
 since I am just adding MODE I should just be increasing extraSpace by 
 1 and not by MODE.length? 
 2) I don't quite understand the mergeDrawableStates method.  If I put 
 it in an IF statement I am getting what I expect, but I think I am 
 just getting lucky.  I don't feel my IF check is correct.  My initial 
 assumption was that I don't do a check and always call 
 mergeDrawableStates but then the drawable never changes.  I have seen 
 where if the extra state is a boolean then the if statement checks for 
 that.  I don't quite know what to do about an enum. 
 3) When I do get it working, my ic_button_a is drawn correctly. 
 However every time when ic_button_c is getting drawn, ic_button_c is 
 resized and stretch to fit the View which includes a background 
 graphic that is larger than ic_button_c.  ic_button_a and ic_button_a 
 are the same size. 

 I have my custom view: 
 com.pkg.CustomView 
 android:background=@drawable/ic_button_bg 
 android:src=@drawable/ic_button 
 android:layout_height=wrap_content 
 android:layout_width=wrap_content/ 

 which extends ImageButton.: 
 public class CustomView extends ImageButton { 

 private static final int[] MODE = {R.attr.mode}; 
 private int mMode = 1; 

 @Override 
 public int[] onCreateDrawableState(int extraSpace) { 
 final int[] drawableState = 
 super.onCreateDrawableState(extraSpace + 1); 
 if (mMode != 0) { 
 mergeDrawableStates(drawableState, MODE); 
 } 
 return drawableState; 
 } 

 public void setMode(int mode) { 
 mMode = mode; 
 refreshDrawableState(); 
 } 
 } 

 I am defining my modes here: 
 resources 
 declare-styleable name=CaptureButton 
 attr name=mode 
 enum name=a  value=0 / 
 enum name=b  value=1 / 
 enum name=c  value=2 / 
 enum name=d  value=3 /

 enum name=f   value=5 / 
 enum name=g  value=6 / 
 enum name=h  value=7 / 
 /attr 
 /declare-styleable 
 /resources 

 My @drawable/ic_button is: 
 selector xmlns:android=http://schemas.android.com/apk/res/android; 
 xmlns:app=http://schemas.android.com/apk/res/com.pkg; 
 item app:mode=c  android:drawable=@drawable/ic_button_c /

There is no ACTION_PRE_BOOT_COMPLETED in the Android SDK. Receivers of

 the task before the completion of booting of the device i.e. before the call

Re: [android-developers] Re: Java.Text.DateFormat returns wrong pattern for en-GB in Android 4.0.x

2012-07-05 Thread Edward Lin

That is correct. It happened on my Samsung Nexus 2 and ASUS Eee Pad (All
those testing devices are using platform 4.0.x). Some other phones like
Motorola Atrix (2.3.6) displayed date with en-GB correctly. All of those
devices are purchased from US.

As I mentioned in the previous email, the Code in my App is:

Locale currentLocale = Locale.*getDefault*(); // at this point, the setting
is using en-GB
dateFormatter = DateFormat.getDateInstance(**Dat**eFormat.SHORT,
currentLocale);
String formattedDateString = dateFormatter.format(new
Date(System.currentTimeMillis()));

 The Date Format should be SHORT for all locales. I just try to use a
generic way to handle the date time localization.

Thanks,

Edward

[android-developers] Buttons do not display properly in Graphical Layout Editor (ADT r20 Helios Mac:)

2012-07-05 Thread Paul

Just updated to ADT 20 and none of the buttons in my layouts are displaying 
properly in the editor. Anyone else having the problem? 

Basically the buttons display with no background (no default grey button 
background as they used to). So if I add a new button to the layout it just 
shows as text only. Also all existing buttons in my layouts do not display 
properly.

During install of ADT 20 there were these issues (showed in a dialog box):
!MESSAGE Marker id 345609 not found.
!MESSAGE Marker id 345610 not found.
!MESSAGE Marker id 345611 not found.

Not sure if those are relevant or not. 

Tried uninstalling/re-installing adt 20 to no avail, same problem (but no 
dialog box errors on second install).

Thanks.

[android-developers] Bitmap.createBitmap to make an immutable copy of subregion, changes bitmap config on 2.2?

2012-07-05 Thread Olof Hedman

Hi,

I'm investigating a bug that I've so far only reproduced on a Samsung i5500 
running Android 2.2.

I'm first creating a bitmap using ALPHA_8 config, like so:

Bitmap textBmp = Bitmap.createBitmap(textureW, textureH, Bitmap.Config.
ALPHA_8);

Then I want to make an immutable copy of a subregion, so I use:

Bitmap textureBmp = Bitmap.createBitmap(textBmp, 0, 0, subW, subH);

I expect it to return an ALPHA_8 bitmap, and it also does this on my ICS 
devices, but on the above phone it suddenly is ARGB_ !

Is this a known problem? Anything I can do, except creating my bitmap 
manually and make a canvas and do a blit?


Cheers,

Olof

[android-developers] Help with intent-filter

2012-07-05 Thread b0b

I've written an intent-filter to receive Picasa images shared from the 
Gallery app on Android 2.x  (on 3+ it is not the same intent but this is a 
different topic):

  intent-filter
action android:name=android.intent.action.SEND /
category android:name=android.intent.category.DEFAULT /
data android:mimeType=text/plain
  /intent-filter

Basically the data (Picasa image URL),  is in the EXTRA_TEXT extra.

This work fine but it has the side effect that my app also registers in the 
Youtube app share menu, and my app do not manage 
youtube links.

The difference between the Gallery intent and the Youtube intent is that 
Youtube add a Url to the intent (pointing to the yoube page).

My question is to know if it is possible (and if so how) to restrict the 
intent above to intent *not* having an Url.

will fix this in the future as I'm sure I'm not alone here.  We have moved 
all images away from GIF and now everything works fine in our game.  We 
will be releasing an update with the same once testing is completed.  So, a 
note to Android developers: Stop using GIF or risk big problems.

 It is definitely nothing to do with WebKit or the browser or similar, this 
 is a standard image view in a game trying to load a simple GIF with 
 transparency.  An interesting update: After updating to the latest build 
 tooks and setting the target SDK all the way up to 16 (for 4.1) the images 
 now show as just all black.  Without any word from anyone from 
 Google/Android, I'm gong to just go ahead and replace everything with PNG 
 files which are all slightly larger than my GIF files which will be a 
 memory hit, but I don't see any alternative if I want a fix done this week.

Re: [android-developers] Wide ListView horizontal scrolling?

 I have a wide ListView that I need to scroll both vertically (for new
 items) and horizontal (to display entire row).
 Is it a good idea to do something like the code below?


I don't know if that will work... It might.  Have you tried it?

What are other options if any?


I would try to redesign each row so that it doesn't have to scroll
horizontally to display everything.  If you are dead set against that, you
could try putting a HorizontalScrollView in each item.

Re: [android-developers] that's a wrap?


 Is there seriously no option for enabling word wrap in Eclipse?

Try asking on a forum dedicated to Eclipse... Not sure if you've noticed,
but this forum is specifically for questions related to developing Android
app using the Android SDK.  How does word wrap in Eclipse fit into this?

 import android.util.Log;
 import android.view.View;
 import android.widget.ListView;

 public class CustomListView extends ListView {

 public CustomListView(Context context) {

 }

 public CustomListView(Context context, AttributeSet attrs) {
 this(context, attrs, 0);
 }

 public CustomListView(Context context, AttributeSet attrs, int 
 defStyle) {
 super(context, attrs, defStyle);
 }

 protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
 super.onMeasure(widthMeasureSpec, heightMeasureSpec);
 }

 protected void layoutChildren() {
 super.layoutChildren();
 }

 View obtainView(int position, boolean[] isScrap) {
 Log.d(clv, getClass().getName());

 Exception e = new Exception();
 e.printStackTrace();

 return null;
 }

 protected void attachViewToParent(View child, int index, LayoutParams 
 params) {

[android-developers] Put 3D object on screen and manage its location

Hi. I need to put a 3D object (obj, mtl or 3ds)  on screen and see that 
image while I'm seeing camera view. That is easy but I need to manage the 
position of the object WITHOUT GPS signal, I mean, if I move the mobile 
phone I don´t have to see the object, only when I focus to the correct 
direction (for example I suppose I can use the compass for this), but I 
need to know how to do it.

Re: [android-developers] Bitmap.createBitmap to make an immutable copy of subregion, changes bitmap config on 2.2?

 Hi,

 I'm investigating a bug that I've so far only reproduced on a Samsung

 I'm first creating a bitmap using ALPHA_8 config, like so:

 ALPHA_8);

 Then I want to make an immutable copy of a subregion, so I use:

 Bitmap textureBmp = Bitmap.createBitmap(textBmp, 0, 0, subW, subH);

 I expect it to return an ALPHA_8 bitmap, and it also does this on my ICS
 devices, but on the above phone it suddenly is ARGB_ !

 Is this a known problem? Anything I can do, except creating my bitmap
 manually and make a canvas and do a blit?

Re: [android-developers] Re: NotificationManager, get methods

2012-07-05 Thread Sergey Tolkachov



 Why there is no read methods in NotificationManager? 

 Because an app can keep track of its own notifications, and an app 
 should not have access to other apps' notifications. 


Because an app can keep track of its own notifications...

It's not an answer. You can keep track of everything you did, but somehow 
you have get methods almost everywhere.
I don't want to have access to other apps notifications (in fact I want, 
but I understand why it's forbidden) 
But I don't really see any reason why 
NotificationManager.notify/cancel/cancelAll return void and not giving any 
indication my notifications.
It's looks like a poor design for me.


  Is it on purpose? 

 Most likely. 

  Will it be added in future releases? 

 You will find out when the rest of us find out, when future releases 
 are released. 

  If not, maybe somebody know how to get Intent object out of 
 PendingIntent? 

 There is no API for that, sorry.

[android-developers] TS play with VideoView

2012-07-05 Thread Leonardo

Hi,

I'm working on an application that needs to play videos in the format TS 
(transport strem), 
however, as the link 
http://developer.android.com/guide/appendix/media-formats.html,; 
I play with the codec H.264 AVC in version 3.0 + Android. However, I wrote 
a simple code 
to play a video file in this format but the error was: ***. When tested 
with a file in 3GP format,
it works right.

The following code snippet:

...
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
   
VideoView videoView = (VideoView) findViewById(R.id.videoView1);

MediaController mc = new MediaController(this);
mc.setAnchorView(videoView);

Uri uri = Uri.parse(http://myserver/files/video.ts;); // with 3GP 
it's works

videoView.setMediaController(mc);
videoView.setVideoURI(uri);

videoView.start();
 }
...

Thanks!

You need to make use of SensorManager and register a SensorListener in 
order to construct a device rotation matrix. Luckily Android already 
provides a method that calculates that matrix which is ready for use in 
OpenGL:

SensorManager.getRotationMatrix()http://developer.android.com/reference/android/hardware/SensorManager.html#getRotationMatrix%28float[],%20float[],%20float[],%20float[]%29
.

*This matrix is ready to be used by OpenGL ES's glLoadMatrixf(float[], 
int)http://developer.android.com/reference/javax/microedition/khronos/opengles/GL10.html#glLoadMatrixf%28float[],%20int%29.
 
 *

 * Note that because OpenGL matrices are column-major matrices you must 
 transpose the matrix before using it. However, since the matrix is a 
 rotation matrix, its transpose is also its inverse, conveniently, it is 
 often the inverse of the rotation that is needed for rendering; it can 
 therefore be used with OpenGL ES directly. *

You also may want to implement an algorithm that reduces the noise from the 
sensor data, otherwise the 3D objects will jitter on the screen. The 
simplest approach is calculating a median and / or weighted average over 
time.

 Yes it is.  Just because you don't like the answer doesn't mean it isn't 
 an answer.

 But I don't really see any reason why 
 NotificationManager.notify/cancel/cancelAll return void and not giving any

 It's looks like a poor design for me.

 Well, to me it would seem like a poor design to have it return something

If you want the Notification to be gone, cancel() it.

If you want the Notification to be there, raise it again (with the

Most situations will fit one of the above two cases. Now, I won't deny

 You need to make use of SensorManager and register a SensorListener in 
 order to construct a device rotation matrix. Luckily Android already 
 provides a method that calculates that matrix which is ready for use in 
 OpenGL:

 SensorManager.getRotationMatrix()http://developer.android.com/reference/android/hardware/SensorManager.html#getRotationMatrix%28float[],%20float[],%20float[],%20float[]%29
 .

 *This matrix is ready to be used by OpenGL ES's glLoadMatrixf(float[], 
 int)http://developer.android.com/reference/javax/microedition/khronos/opengles/GL10.html#glLoadMatrixf%28float[],%20int%29.
  
 *

 * Note that because OpenGL matrices are column-major matrices you must 
 transpose the matrix before using it. However, since the matrix is a 
 rotation matrix, its transpose is also its inverse, conveniently, it is 
 often the inverse of the rotation that is needed for rendering; it can 
 therefore be used with OpenGL ES directly. *

 You also may want to implement an algorithm that reduces the noise from 
 the sensor data, otherwise the 3D objects will jitter on the screen. The 
 simplest approach is calculating a median and / or weighted average over 
 time.

[android-developers] Re: Put 3D object on screen and manage its location

With that device rotation matrix you can only rotate your objects around
the screen, where the rotation center point is the center of the device.
This is independent of GPS location coordinates, and as the name of that
matrix suggests, it is really rotation only, not translation (moving around
the objects on any axis).

But to answer your question: yes, it is possible to just use the sensor
data without GPS and have 3D objects move around on the screen. And it will
work well for most use cases, like augmented reality games where you
usually sit as a player and move the camera around.

If you need to change the positioning of the 3D objects according to the
current device location and movement, it gets a bit more complicated.

You could make use of the GPS coordinates for translation but it wouldn't
be real time suitable, because GPS alone is usually not precise enough. You
need to combine several sensors (including the camera) for making an
augmented reality app possible that gives a seamless experience and allows
the user to freely walk around.

You could make use of acceleration sensor data for getting an idea of the
current device / user movement direction. With that information you could
predict a translation until the next GPS location update gives you
certainty about the current location.

You also could make use of realtime image analysis for calculating the
current movement direction based on changes in the video preview frames.

As I wrote at my first post:

developers to make a couple of things in code)
I am doing exactly what you suggest here. The problem is that it's 
not straight forward approach and it require from developers to right 
special code (like giving action type to intent). Another problem that it 
will not give me opportunity to verify notification ticker (I am doing it 
right now by asking developers to add it to intent category)


  It's not so weird scenario to be able to check that some notification

I've isolated the problem and this has nothing to do with ArrayList or 
Vector and everything to do with Garbage Collector.  Both of those are 
working fine exactly as I coded them when I run the code in an isolated 
activity.  Apparently GC is destorying my activity and recreating it and 
my onSaveInstanceState()/onRestoreInstanceState() code isn't working 
correctly.

[android-developers] Re: HELP! Google removed my app with millions of users!

2012-07-05 Thread isopropanol

ICS doesn't have a hard menu button anymore, so the menu button occupies a 
bar at the bottom of the screen on apps that expect it and don't have their 
own soft-button.  The issue could be that people accidentally click the ad 
trying to hit the menu button (complete speculation), so placing the ad at 
the top would resolve that.

That falls into the I'll put it wherever they want as long as they tell me 
where they want it category you mentioned already.

Before you mentioned the app name I was thinking it might have fallen into 
the intellectual property category if someone sent a DMCA-type notice, 
but that shouldn't be the issue here.

 Without warning, a few days ago my long standing successful app was 
 removed from the play store. The app has been around for over 2 years now 
 and has around 1.5 million active users, and nearly 5 million downloads. 
 It's been in the top 5 of its category for well over a year. It has over 
 65,000 ratings with an average of 4.6/5.

 The email I received said that the app was removed because Google says 
 *Violation 
 of one or more of the following provisions of the Content Policy: 
 spamhttp://www.android.com/us/developer-content-policy.html#spam
 , intellectual 
 propertyhttp://www.android.com/us/developer-content-policy.html#IP, 
 and impersonation or deceptive 
 behaviorhttp://www.android.com/us/developer-content-policy.html#impersonation
 * and more specifically because *core features of your application 
 causes users to accidentally click on advertisements*

 First of all, the ads are hardly accidentally clicked... The highest 
 average click rate I've ever gotten was 0.8%. Even still I've read over the 
 Content 
 Policy http://www.android.com/us/developer-content-policy.html as well 
 as the Distribution 
 Agreementhttp://www.android.com/us/developer-distribution-agreement.html 
 and 
 neither call out specific ad placement rules, guidelines, or suggestions. 
 The ad placements are also similar to hundreds of other most popular apps...

 I'm more than happy to upload a compliant version of the application 
 putting the advertisements in whatever position is deemed acceptable by 
 Google. I'm not unethical or a con-artist, I'm a recent college grad from a 
 smaller town after all... Re-releasing the application under another 
 package name would be unfair to the 1.5 million active users out there as 
 they wouldn't get the update notification or keep their settings.

[android-developers] null is the loneliest number

2012-07-05 Thread bob

I'm looking at this function in Activity:

public Window getWindow ()
Since: API Level 1
Retrieve the current Window for the activity. This can be used to directly 
access parts of the Window API that are not available through 
Activity/Screen.
Returns
Window The current window, or null if the activity is not visual.

It says it returns null if the activity is not visual.

In layman's terms, when does it return null?  What constitutes a not 
visual activity?

Re: [android-developers] null is the loneliest number

Perhaps an activity that only launches another activity...  There is a
theme you can use when creating an activity that doesn't have a UI:

android:theme=@android:style/Theme.NoDisplay

[android-developers] How to improve performance for drawing with background image?

2012-07-05 Thread limtc

Hi,

I have done a few painting apps and they all worked fine as long as I don't 
use background images. Once I added background image, the painting becomes 
sluggish.

I have tried 2 methods of adding background image:

- use setBackgroundDrawable
- in the layout, I created an overlapping imageView with the background 
image using FrameLayout

Once I removed the background image, the drawing is smooth again. Is there 
any suggestions for me to improve the performance?

Thanks!

[android-developers] Updating text in a DialogFragment

2012-07-05 Thread Raymond Rodgers


Hi folks,
I've been searching for a solution to this problem for the last 
couple hours but haven't turned up a solution. I'm very new to using 
Fragments, but building an app based around the ViewPager in the support 
library. For the most part, I haven't had any problems, but I am running 
into a situation where I'm using a DialogFragment in the hopes of 
building a progress indicator while my app does some things in the 
background. I have an indeterminate progress indicator running in my 
DialogFragment, and I want to update one of two TextViews I have in the 
dialog as it progresses. I'm sending updates from my background service 
 thread via a Handler that is then to update the designated TextView. 
The problem is, that TextView isn't updating. I thought it might be an 
issue with the static field I assign the result of the findViewById() to 
(thinking that it may not exist before the dialog is displayed), so I do 
a check and secondary findViewById() prior to changing the text via 
TextView.setText(). Unfortunately, it appears that the TextView field is 
always null, and so the view isn't getting updated.


What am I failing to do? Do I need to do something with 
FragmentTransaction or FragmentManager in order to update this TextView?


Thank you for your assistance!
Raymond
