Re: [android-developers] Re: Doubt about heap size

[Francisco M. Marzoa Alonso]

Thanks a lot,

I thought that something like that may be happening.

But I have not very clear yet how this memory assigment works, due to
the DDMS feedback: when my app runs on the 2.1 emulator it shows 3M of
available heap space. In a given moment I have ~75% of that heap memory
allocated. Assuming it should grew dynamically, it is expected that when
I try to load a bitmap that does not fit on the 25% free heap memory, it
should grew to some more than 3M and load the bitmap within the new heap
available space. But instead of doing that, it crashes with an Out of
memory exception. The bitmap is just 800x480 pixels,  that with four
bytes per colour (including one for alpha) should occupy less than 1,5M
in RAM.

I have managed to solve these problems -at least for now- making a more
intelligent use of the heap, recycling bitmaps sometimes when they are
not needed for a long period, and loading them again from assets or
resources when needed. But I am still curious about this behaviour
because it may be a real problem for me further, in this app or in other
one.

Best regards,

Re: [android-developers] Activity Animation

[Francisco M. Marzoa Alonso]

Hi,

Emulator is really slow, you should not measure
your app performance based on emulator results.

The speed of an animation depends on the speed of the device: the faster
the device, the faster the animation.

You must use some kind of method to sync your animation framing so it
runs at same speed on all devices. For example, if you plan to show 25
frames per second, i.e. one frame every 40 milliseconds, you may
calculate the time for next frame based on System.currentTimeMillis() + 40.

It should be something like:


// Init this value on the constructor, for example
nextFrameTiming = 0;

...

// This could be wherever the image its drawn or prepared to be drawn,
depending on how your code works
if ( System.currenTimeMillis >= nextFrameTimming ) {
nextFrameTiming = System.currentTimeMillis() + 40;
changeFrame();
}

So you only change to a new frame as fast as once each 40 milliseconds.
Note that this will be useful to make the animation slower in devices
where it runs too fast, but obviously it will not made it to run faster
in devices where it runs too slow due hardware limitations.

[android-developers] Doubt about heap size

[Francisco M. Marzoa Alonso]

Hi there,

I have read that the maximum heap available for an app is 16M, despite
that there may be higher on newer devices.

Anyway on a 2.1 emulator with Eclipse/DDMS my available heap shown is
just about 3M, while in  my SGS2 real device shows about 5M of available
heap. As you see, a lot of lower than 16M.

My app runs fine on my SGS2, but it crashes complaining about not having
sufficient heap memory on the emulator, and I have received a few
reports with the same error on Google Play.

I am currently doing an effort to decrease heap consumption, but I
wonder why DDMS shows values so low and if some devices may actually
have less than 16M of heap memory.

My app is developed for Android 2.1+

[android-developers] l10n and coordinate mapping on an image

[Francisco M. Marzoa Alonso]

Hi there,

I am using a bitmap with several parts that can be touched by the user
as they were buttons. These parts may be bigger or littler depending on
the language.

Currently, as I have split English and Spanish version into two
different apps, I just have the coordinates hardcoded in my Java classes.

But now I am integrating both languages on the same app, having yet done
the different string and image resources, but I do not know what is the
best approach to this problem.

I could make some hack, like encoding the coordinates between an string
using string file resources, and parsing these as needed to get again
the coordinates. But I think there should be a better way and I do not
want to do -again- dirty code that I will need to change sooner than later.

Any ideas?

Thanks a lot in advance,

Hi,

Well, the other approach also seems to solve the problem, so as both

between them. And your answer didn't help me, indeed.

BTW, there is no need of being so high-handed when answering.

[android-developers] Formatted string and localization problem

Hi there,

I have a l10n string that I need to format later, it looks like this:

Couldn\'t load music file %s

But Eclipse complains about a couple of errors on XML parsing:

- error: Multiple substitutions specified in non-positional format; did
you mean to add the formatted="false" attribute?
- error: Unexpected end tag string

It dissapear adding that formatted="false" attributed, but I am curious
about that...

I use these %s because I will use Formatter.format later to build an
string with the file name that raises the exception and the e.toString()
output.

Re: [android-developers] Re: Localization doubt

[Francisco M. Marzoa Alonso]

After thinking it a bit, I will relay on system's language and so
Android's l10n for user's interface, and threath the game words language
independently. I think it is the better approach.

Thanks for your help, it has been useful for me to find the best path.

It seems not to exists an straight way to do it. That guy says "this is

complain about it not working well.

I am afraid will end implementing my own l10n handling regardless

Re: [android-developers] Re: How to move an app to another on Google Play

[Francisco M. Marzoa Alonso]

Thanks for the point, but as far as I have hardcoded strings on my Java
code, I need to change my code... Also the concept of code may be
understood on a wider manner that includes not only Java code, but also
XML resource files and other things like that.

Of course I have been reading that guide, and also the Helo l10n example.

Anyway thank you very much for the interest,

[android-developers] Localization doubt

[Francisco M. Marzoa Alonso]

Hi there,

I am starting with l10n and I have a doubt on that.

As I have read, the system will choose the l10n resources for me based
on user's configuration, but I planned to give the users of my app to
choose a different language from configuration one if they want.

My app is a casual game for guessing words, it is in Spanish and
English, but some Spanish people -me among them- may find useful to play
also the English version of the game so they improve their English
vocabulary, and vice versa.

Is there any way to tell the system to use resources of a given
language, regardless system configuration?

Thanks a lot in advance,

Ok, it looks pretty straightforward when you know how localization works
on Android, but I released my first application after reading just the
first half of the book "Beggining Android Games" that does not cover
localization and many other things, so I did it with the limited
knowledge I had on that moment, and most of the time recycling sample code.

So if I had invest more time in learning, perhaps I had released the
application with localization even faster. But I could not know how much
time I could need to learn those things before learning those things...
chicken and egg problem.

Also my lack of experience didn't let me figure out the problems that I
could have further -as I had now- doing that way.

[android-developers] How to move an app to another on Google Play

[Francisco M. Marzoa Alonso]

Greetings,

Well, I know the subject sounds weird, but I do not know how to express
it better in a brief.

The question is that I have created an application in two languages, as
it was my first one and I want to release it ASAP, I simply create two
different applications for each one (Spanish and English), and uploaded
them such way to Google Play.

I have had no major problems with this, apart from loosing positioning
as installations and ratings are separated, but now I have planned to
release a new version in Italian and may be later in German, and I do
not want to keep them separated because I prefer that all installations
and ratting are in one application account instead of spread among
several ones.

Also adding improvements and fixing bugs will be easier with just one
application than with one for each language.

Moreover, I for each language I must maintain two versions: free with
ads and per pay without them. Not a major problem with just two
languages neither, but a bit annoying with four.

I have yet a clear idea on what changes I must do to my code for
supporting several languages at once, however this will generate some
problems with Google Play that I have not very clear how to address.

The first problem is that if I create a new application package, I will
lost all ratings and installs on previous one. I think the best solution
may be reusing the application package for the Spanish version, that is
about reaching 100 000 total installs and 1400 comments, and send the
English version to the trash, loosing just about 15 000 installs and 75
comments.

So, I am not specially concerned about that. But it happens that appart
from free versions of my app, I have also released per pay versions in
both Spanish and English. I do not care about loosing both the comments
and the installs on those, since I have just one comment in the English
version and less than 70 installs counting both English and Spanish, but
If I just discontinue the development of one of those, the users will
complain as they have paid for it.

I do not want to just refund them for the old application, since I am
pretty sure that I will lost money because many of them may decide to
keep the old version even without updates instead of buying the new one
with the refunded money. So I have considered offering refund on the
purchase of the new app instead for those users that can probe that they
have purchased the old one. The question is: what about the 30% of
Google Play? It will be returned to the user also? It will be charged to
me even when I refund the user?

Well, any ideas on this issue as a whole are welcome.

Thanks a lot in advance,

[android-developers] UTF-8 encoding and decoding

[Francisco M. Marzoa Alonso]

Hi,

I am implementing an standalone client/server protocol to make one of my
games online capable. One of the problems I have found is that some
strings passwed between client and server may have characters that must
be encoded on UTF-8 (like spanish ñ for example).

The first thing I though was using hexadecimal notation for each char,
so an string like ESPAÑA will be enconded and sent as:

004500530050004100D10041

But I rather like to avoid this, since it generates an unnecessary
network load for just one char, and I expect to have hundreds of
concurrent connections, so it is important to loose all the fat I can...

I have found this altenative notation may be a good alternative:

ESPAU+00D1A

But I did not found where it is documented, also I do not know if
Android has native functions to handle this, that may be an interesting
advantage for prefering one notation over another.

Also this one, claimed to be "JavaScript escapes" looks interesting,
with the same load than the previous one:

ESPA\u00D1A

I am using this online tool for my testings:

http://www.rishida.net/tools/conversion/

Well, bearing in mind that the client will be written in Android, and
the server in PHP, what you think should be the best option for encoding
UTF-8 chars during transmission?

Re: [android-developers] Changing "hosts" file on an Android device

[Francisco M. Marzoa Alonso]

I finally ending just using my hosting provider DNS and creating there
subdomains of actual domains for development, using internal IP
addresses of my network instead of public ones.

It works perfectly and I do not need to set up and keep running my own
DNS server.

Thanks by your advices. I do not need validation against schema nor XML

Re: [android-developers] Changing "hosts" file on an Android device

[Francisco M. Marzoa Alonso]

Hi Kristopher,

It is just for development, but I do not want to root my own devices
since, you know, I want to try my applications in devices closed to
users ones, that are not rooted usually. Moreover, If I root my devices
it may not work properly with services like Google Play, and I use them
also to check downloaded packages from Google Play and so.

And I have not infrastructure yet to have several devices rooted and
several non-rooted for checking both things. To be honest, I have just
two devices for development: one is my own phone and the other is my
wife's one X-D

Things may be easier if my DLS router and WIFI AP had DNS server
capabilities, but it has not, so I should configure a Bind or something
similar in some of my other computers and then instruct the router to
use its IP as primary DNS server for DHCP configuration.

A pain in the...

The other way could be to do this programmatically, so... is there any
way to configure a host resolution table just within my application
through Android?

I cannot just use the IP addresses directly, because I will access some
virtual servers through HTTP and the requests to these must include its
domain name, since they share the same IP address.

Regards,

There are several vendor-supplied printing apps for Android. If you

[android-developers] Changing "hosts" file on an Android device

[Francisco M. Marzoa Alonso]

Hi there,

When I develop a dynamic web site I used to change the /etc/hosts file
on my linux boxes and the equivalent on Windows ones to test the site on
different browsers, so I add a line in the way of:

192.168.1.21devel.mysite.com

So when I put http://devel.mysite.com on a browser, it connects to my
development Apache server.

So what I'd like to do it is the same on my Android device, I think I
cannot edit /etc/hosts file on it at least while it is not rooted, but
if there is other way to do this it will be enough.

I know there are complexer ways to do this, like setting up a DNS server
on my own network and give it through DHCP to the device when its
connected to my WIFI access point, but I rather like to do it in a
simpler manner if there is any...

I use Eclipse for development, so if there is a chance to do something
via DDMS or using command line tools like adb, it will be welcomed.

Re: [android-developers] Re: Data interchange with a PHP server

[Francisco M. Marzoa Alonso]

Hi,

For JS it is clear that JSON will be faster, but what is the better
choose in Java for Android? I mean, is it JSON parsed faster than XML on
Dalvik?

And for the authentication I used to use PHP sessions and cookies when
developing web pagers.

Will be this also the prefered way to do it with the Android HTTP
client? The other way I am considering is to give the client a token
from the server after authentication and pass it in every POST or GET
request to the server.

This has the disadvantage of having to take care of passing it in every
request, but on the other hand avoiding cookies should made the code
simpler and easier to debug.

Regards,

I answer to myself, JFTR:

For some reason SoundPool were unable to load a wav sample that in fact
works in every other player that I have used. So I simply ended using
another file with a different format. Here is the format of the
offending file, as told by mplayer on my GNU/LiNUX box:

|Opening audio decoder: [pcm] Uncompressed PCM audio decoder
AUDIO: 96000 Hz, 1 ch, s16le, 1536.0 kbit/100.00% (ratio: 192000->192000)
Selected audio codec: [pcm] afm: pcm (Uncompressed PCM)
|

And here it is the one for the other file that does work:

|Opening audio decoder: [pcm] Uncompressed PCM audio decoder
AUDIO: 22050 Hz, 2 ch, s16le, 705.6 kbit/100.00% (ratio: 88200->88200)
Selected audio codec: [pcm] afm: pcm (Uncompressed PCM)
|

There are many differences, but the point is that the second works, so I
simply discarded the first one and move into the second. Knowing this if
I needed the first sound sample, I just need to adjust its rate and
channels with an audio editor like Audacity to solve the problem.

Why it did not just work in first case? Who knows, but if I can solve it
so easy... who cares at all?

Re: [android-developers] want to install a software .exe from my Android App

[Francisco M. Marzoa Alonso]

It looks, at least for me. May be my own ignorance, or perhaps that I
have not understood you very well.

My point is that Android OS is a linux based system, where you cant exec
MS-DOS/WINDOWS binary executable files like those with .exe extension
(at least not directly, you can do it with some using WINE for example,
but thats another history...).

Also if you develop your application the common way, i.e. in Java with
Android SDK, it will run on a sandbox within the system, on the Dalvik
VM, so your chances to execute native code are even less (though I think
you can use JNI for the task), and to be honest I do not know how to do
that and what issues you may found (may be you need even a "rooted" device).

Anyway, the point is that you cannot execute a Micro$oft .exe binary
file within your Android device. And installing WINE or something for
the task seems to be too complicated for just considering it.

Maybe I am wrong anyway.

Regards,

Re: [android-developers] Google play stats stalled

[Francisco M. Marzoa Alonso]

Hmmm... I have this message on my console:

"Issues with statistics export
Temporary issues exporting statistics

"

It is not exactly the same, since I do not want to export stats, but may
be it is related: if they are working on solving stats exporting, may be
they are retaining the whole thing... thought...

I will wait til twomorrow before complaining...

[android-developers] SoundPool error "Unable to load sample: (null)"

[Francisco M. Marzoa Alonso]

Hi there,

I am facing an "Unable to load sample: (null)" error with the SoundPool,
while trying to load a sample (not surprising, yeah?).

I have discarded all common flaws that should raise that kind of error,
so the file does exists (I can see it there), the file is readable
(assets manager seems to read it with no problem), and the file is not
corrupt (I can reproduce it with a wav player without problems).

So I do not know what could be the cause of this error. Here is the code
snippet:

try {
AssetFileDescriptor assetDescriptor = assets.openFd(filename);
int soundId = soundPool.load(assetDescriptor, 0);
return new AndroidSound(soundPool, soundId);
} catch (IOException e) {
throw new RuntimeException("Couldn't load sound '" +
filename + "'");
}

assets is an AssetManager instance, and it loads pretty well other
samples in the same directory. It does not raises an IOException, so it
is pretty clear that the file is there and it is readable, but when
executing the soundPool.load line, it complains with the error "Unable
to load sample: (null)".

Any ideas?

Thanks a million,

[android-developers] Google play stats stalled

[Francisco M. Marzoa Alonso]

Hi,

The stats on my Google Play developer console seems to be stalled since
yesterday. It has been updating between 12:00 and 13:00 GMT, but today
at 15:40 GMT they are showed outdated. I have the same active install
that I had yesterday, and the last day shown on graphics is 28 May.

I rather like to know if this is a general issue or it is affecting just me.

Anyone with same problem?

Thanks a lot in advance.

Nice to known that , thanks Treking. Although documentation is very vast

That's right. Note you can use market:// url instead http:// scheme so
the link is opened directly with Google Play.

Re: [android-developers] Re: Send the user to Google Play application's page

[Francisco M. Marzoa Alonso]

Hi,

First, thanks by your fast answer.

On the issue, I will try to be the less obstrusive as possible, showing
the message just one time for the same user for the rest of his life,
and only if the user has been playing the game for a long time, so he
likes it. If it says "no", I will not ask again.

On the code, could you develop a bit more this idea?

"make it so that a new intent is passed with the URL for your app, using
the ACTION_VIEW"

It is my first app for Android, and also I have no write a line of Java
code until this for more than 15 years...

Thanks a lot in advance,

[android-developers] How to force an exception?

[Francisco M. Marzoa Alonso]

Hi there,

Just for debugging my code I rather like to simulate the case an
exception is raised, and I do not know how to do it.

The code is the following:

try {
AssetFileDescriptor assetDescriptor = assets.openFd(filename);
return new AndroidMusic(assetDescriptor);
} catch (IOException e) {
throw new RuntimeException("Couldn't load music '" +
filename + "'");
}

What I want to do is to force the IOException after 

AssetFileDescriptor assetDescriptor = assets.openFd(filename);

So the code goes into the catch block.

How could I do that?

Thanks a lot in advance,

[android-developers] Noise between FX sounds and music

[Francisco M. Marzoa Alonso]

Hi there,
 
I am facing problems when playing at same time music and some FX sound.
The FX sound is a "click" similar to the click of the mouse. It sounds
fine when playing alone one time, although it gets some noise at the end
of the reproduction when trying to repeat it too fast.

But when it is played with some background music, it does the noise at
the end (like a "puk" or so) every time.

Some ideas?

[android-developers] have picture taken show in preview and save on request

[K M]

I have an activity that starts a camera and after the picture is taken
it shows an alert dialog so user can choose save, cancel, retry. I
cannot seem to delete the picture data on cancel, nor transfer the
image to another activity, in the same app, on save. There is no error
showing, it just doesn't clear the data and I don't know how to access
the data to use in an imageview on the other activity. Here is the
relevant code:

PictureCallback jpegCallback = new PictureCallback() {
  @Override
  public void onPictureTaken(byte[] data, Camera c) {
tempdata = data;
done();
}
};

void done() {
Bitmap bm = BitmapFactory.decodeByteArray(tempdata,  0,
tempdata.length);
final String url = Images.Media.insertImage(getContentResolver(), bm,
null, null);
bm.recycle();
Bundle bundle = new Bundle();
if(url != null) {
bundle.putString("url", url);
Intent mIntent = new Intent();
mIntent.putExtras(bundle);
setResult(RESULT_OK, mIntent);
}else{
Toast.makeText(this, "Picture can not be saved",
Toast.LENGTH_SHORT).show(); }

AlertDialog dialog = new AlertDialog.Builder(this).create();

I have 3 buttons in the dialog, save, cancel, and retry.  The retry
works fine, I need to clear the data on cancel and recall the save
data in another activity if they choose save.

[android-developers] how to use android library project jar and resource?

Hi folks,

I have jar and resource folder of an android library project.
I wanted to refer the resources of the library project in my project from
eclipse.
I do not want to refer the library project source code in the application
project since android has provided an option to export the library jar and
res seperately from r15.
Though I have an option to include jar via properties-> library -> build
path, I couldnt figure out where the resource should be specified.
I using android 4.0.3 - r15.
Could someone help me on this?

Re: [android-developers] Connectivity Manager does not return Active network information

[sha m]

Hi Mark and Robert ,
   Thanks a lot for the information.
I had my bluetooth active and connected to another mobile, but still
returned null in API level 7.
So it means this can be verified only above API level 13?

My intention was to check the VPN connection.
Could you please guide me on that?

Regards,
Sha

[android-developers] Re: Flash player in background

[M CC]

Hello asxz,
thank you for posting this issue of yours.
Unfortunately I cannot help you with the code (I wrote a couple of
apps myself a few months ago but not using Flash Player).
What I can tell you is, as far as I know, the Flash player is (quite
strangely) made not to play/function when in background. I hate this
because for example
there is no way to listen to a youtube video music without having to
look at the video itself (in some case the video is a still image!!).
Have a look at this:

My application connects to website which requires username and password. 
After POST is done http GET cannot access next page after login.
After searching for solution I cam e to conclusion I need to send cookie 
with http POST.
Tried this 

DefaultHttpClient mHttpClient = new DefaultHttpClient();
BasicHttpContext mHttpContext = new BasicHttpContext();
CookieStore mCookieStore  = new BasicCookieStore();
mHttpContext.setAttribute(ClientContext.COOKIE_STORE, mCookieStore);

HttpResponse response = mHttpClient.execute(mRequest, mHttpContext);

But it doesnt work.
Other examples shows usage of
httpclient.getCookieStore().getCookies();

My problem is there is no method getCookieStore in http client.

[android-developers] JNI and caching jobject "thiz"?

[M J]

Hey guys,

I nned your help. I am currently developing an application which uses
JNI and native sockets. The problem is that I have to call Java code
if some packages arrive on the native socket connection. Currently I
am using CallVoidMethod to do that. The JNIEnv cannot be cached so I
get it like this:

inline JNIEnv *get_env()
{
JNIEnv *env;
jvm->GetEnv((void **)&env, JNI_VERSION_1_4);
return env;
}

The jmethodID I is cached and initialized on startup. My only problem
now is, how can I get the jobject? Currently I am making a global
reference on the parameter jobject thiz, which is passed to my init
function.

Is this okay? I am asking because I am having some trouble with that,
eg. the reference to the local and the global obj are exactly the
same. And when I a call DeleteGlobalRef on the global reference there
is a warning in the log cat output that this reference does not exist
and the app crashes.

I also tried using the local reference but then the CallVoidMethod
crashes and the output says this reference does not exist, so I think
I am on the right way.

Thanks in advance!

[android-developers] changing ImageButton image

[m l]

I am trying to make this simple app. Any help would be appreciated,
thank you.
What I want it to do.
1: Show a clickable image ( imageButton)
2:When clicked  change imageButton to second image.
3:Then play a sound.
4:Wait a few seconds ( I have been using thread sleep() )
5:Change image back to the original picture.

Sounds simple right?
Well what I am getting is this.
1: Show a clickable image ( imageButton)
2:When clicked it plays the sound.
3:Waits a few seconds.
4:Then sets the imageButton to original. ( I know this part happens
because I tried 3 pictures. A starting image, photo2 and last photo1
as a test to see if it was even trying to change the imageButton)

The first Image change ( step 2)  never happens , even though when I
step through the app with a debugger it shows it going to that point.



Code---

package my.picture.changer;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageButton;

public class PictureChangerActivity extends Activity {

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  setButtonClickListener();
 }

 public void setButtonClickListener() {
  final MediaPlayer mp = MediaPlayer.create(this, R.raw.mysound);
  final ImageButton imageButton1 = (ImageButton)
findViewById(R.id.imageButton1);
  imageButton1.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
// set button image to photo2
imageButton1.setImageDrawable(getResources().getDrawable(
  R.drawable.photo2));

mp.start();// play sound
sleeper();// wait 5 seconds
// tried moving sleep out of method to
see if that made a difference (no)
// change button image back to photo1
imageButton1.setImageDrawable(getResources().getDrawable(
  R.drawable.photo1));
   }
  });
 }

 private void sleeper() {
  // wait 5 seconds

  try {
   Thread.sleep(5000);
  } catch (InterruptedException e) {
   e.printStackTrace();
  }
  return;

 }

}

Will the replaced package itself receive the broadcast? As far as I
can tell the only way to get such notification is by means of
ACTION_MY_PACKAGE_REPLACED (Android 3.1.).

[android-developers] Could not find hello-world.apk

[Francisco M. Marzoa Alonso]

Hello,

I'm starting writting android games with a book called Beginning Android
Games, of Mario Zechner. I've written the first Hello World application
after installing everything on my Ubuntu 11.10 laptop, and I
doublechecked that I have followed the instructions on the book, but
when I try to run it Eclipse says:

Could not find hello-world.apk!

Build Automatically option is enabled within Project, so it should be
generated automatically, but it seems like it should not.

This is the complete output I get when trying to run it:

[android-developers] native udp socket & sleep mode

[M J]

Hey guys,

I am currently developing an app, where I need a udp connection to a
server. The code which communicates with the server is written in C,
so I am using the ndk and I open a posix udp socket. I send every 30
seconds a message to the server to register and to keep the connection
alive.

My problem is now that sometimes when the phone is in sleep mode (e.g.
display is off) messages from the server are lost. I only have this
problem in UMTS (3G, ..), not when I am connected via Wifi.

My question is now, how does the android system react in sleep mode
when a udp connection is open, especially when using native sockets.
Will the connection be ignored? Or just closed sometimes?

You can read it in HTML:

Searching will be limited to the currently displayed page, of course,

[android-developers] Creating a layout from XML Parsing

[Adam M]

Hi all

I am trying to create an application where the widgets of the layout,
that is the TextViews, EditTexts etc are all stored in an XML file,
which is then parsed and added programatically. I also need to be able
to set the location on screen from this XML file. Reason this is
required is that I want to be able to customize layout just by
changing the XML file, which will then be parsed and update the
layout.

I have been trying a few things to get this working, but its proving
rather complicated. I have tried searching in many different places,
and I can't seem to find any tutorials or examples of this type of
thing. Would anyone be able to point me in the right direction, or
give me any pointers?

Thanks in advance

[android-developers] Re: getdisplay width height and assign it to static int

[Adam M]

Use


Display display = getWindowManager().getDefaultDisplay();

Then do

int height = display.getHeight();
int weight = display.getWidth();

Now you wont be able to assign these as static, as if you try to get
the width and height outside the onCreate method, and then run program
it will crash. Although I am not sure why you would need to assign the
width and height as a static variable. I suppose one way to get around
this would have a class with a static height and width variable and in
your main class where you declare the onCreate method, use Window
Manager, get width and height, then pass the variables from there into
the static variables in the other class.

Already did this. Looks like all clauses in the switch fail if the

Extra additional information: the problem also happens when I build on

Can anybody help me to debug this? I'm whiling to fill a bug report,
but I need additional information. I suspect that the problem is

[android-developers] Mysterious behavior of switch statement inside onActivityResult

[Carlos A. M. dos Santos]

Hello,

I have the following code in class MyActivity:

public static final int REQ_CODE = 0x7fff;
...
startActivityForResult(intent, REQ_CODE);
...
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d(TAG, " onActivityResult: " +
Integer.toHexString(requestCode));
switch (requestCode) {
case 0:
case REQ_CODE:
Log.d(TAG, " REQ_CODE ");
break;
default:
Log.d(TAG, " Equals: " + (requestCode == REQ_CODE));
}
}

When I run it I get the following log messages:

D/MyActivity(11505):  onActivityResult: 7fff
D/MyActivity(11505):  REQ_CODE 

Now for the mystery. If I comment-out the "case 0" clause I get these
log messages:

D/MyActivity(11471):  onActivityResult: 7fff
D/MyActivity(11471):  Equals: true

If I comment-out the "case 0" clause and change the value of REQ_CODE
to 0x7ffe I get a correct result again. To make the case even more
mysterious, a similar code works perfectly well in another class,
inside a method overriding Handler.handleMessage(Message msg).

My environment:

- Ubuntu 11.10 x86 (32bit).
- Android SDK Tools r15
- ADT Version: 15.0.1.v20031820-219398
- javac 1.6.0_26
- Project target API: 7 (Android 2.1)

Additional information:

- Building with ant does not make any difference.
- Changing Java compliance to 1.5 does not make any difference.
- The problem can reproduced 100% of the times, both on Nexus S with
Android 2.6.3 and on emulator running Android 2.1.
- No, I'm not drunk!

It is not fetching the IP address. The
"store.mydomain.com/185.165.192.15" you see is just the result of
InetAddress.toString(). Please post the entire stack trace contained
in the exception. Also, tell proguard to keep line numbers and file
names:

It's not safe.

Use the account manager. Ask the user to create an account and save
the boolean variable along with the account credentials. Be warned,
however, that for security reasons apps installed on the SD card will
have their accounts removed each time the SD card is unmounted/mounted
(including power-switching the device).

This can be managed at the server side, revoking the user account.

Be warned that HP does not officially support that API. It can change
or even disappear in the future.

[android-developers] ADT 15: opening declaration in library project jumps to read-only source

[Carlos A. M. dos Santos]

Hi,

I have ClassA, declared in library project ProjA, and ClassB, declared
in project ProjB. ProjB references ProjA as a library, therefore ADT
creates a ProjA_src link at the root folder of ProjB. This link can
*not* be included in the Java build path, otherwise the build fails
due to classes being added twice. So far, so good, but if I put the
cursor on ClassB, over a reference to ClassA, and hit "F3" Eclipse
opens a read-only tab with the source code, entitled "ClassA.class",
not the source under ProjA_src. This is a regression compared to ADT
13 and before, in my opinion, so I have two questions.

Does anybody know a workaround?

Did anybody fill a bug report, already?

Thanks in advance for your help.

Unfortunately there is no official "print" action. Some printing
applications answer to the "share" and/or "view" action, but this is
just a workaround.

[android-developers] Android: Leaked IntentReceiver exception is being thrown even though I call unregisterReceiver

[vijayakumar M]

Hi Friends,

I don't understand why I'm getting this exception when hitting the back
button. I have the IntentReceiver registered in the onCreate method and it
is supposed to be unregistered in the onPause method. My Log.w() call
inside of the onPause method leads me to believe that the
unregisterReceiver() method is being called, but I am getting this
exception still... please any help me

Re: [android-developers] Types of mobile application

Hi All,

It seems to me only native and webview  are the two types of mobile
application we can create. using mobile jquery we can create web
application that make effective UI in mobile devices.

Correct me if i am wrong, and another type of mobile app we can create in
android?
