So i tried using the SDK manager to insure i had the proper play services 
but I keep getting the following error from my SDK manager in Android

This is a clean install, and i thought it may be my firewall settings but 
after turning off my firewall completely it is still happening:

[android-developers] Converting YUV to RGB with only one SurfaceTexture in OpenGL ES 2.0

[Erik Hellman]

Hi!

So I found a bunch of examples of how to convert YUV to RGB in OpenGL ES 
2.0, but they all require me to give to buffers (luminance and chrominance) 
as input to the shaders. 

What I want to do is to use the SurfaceTexture that I initialise from an 
OpenGL ES 2.0 texture I allocated. The camera gives its input to the 
SurfaceTexture correctly, but I can't display draw the texture in the 
fragment shader. I'm assuming this is because the format is NV21 (YUV) and 
the normal texture2D() shader function can't process that correctly.

Now, the question is how do I make this work? Is it possible to convert 
NV21 to RGB in a shader without first splitting the NV21 buffer in two 
separate buffers? This would sort of defeat the purpose since I want to 
process the entire frame in OpenGL. Having to copy buffers manually when I 
can get the entire frame into OpenGL seems like a waste of CPU.

I'm pretty sure that the underlying camera framework in Android converts 
nv21 to rgb on the fly, since I can draw the preview to a SurfaceTexture 
that I receive from a TextureView, but is this conversion then happening on 
the CPU or is there some secret yuv2rgb shader in the Android source code 
that I can't find?

Thanks!

// Erik

   Toast.makeText(getBaseContext(),

 My question is, is it a right method for sending group sms. Or should I 
 create pendingIntent with broadcast receiver to monitor the sending process 
 and wait inside the for loop until each message send finished to send next. 

 Thanks in advance

[android-developers] Single Application or Kiosk Mode

[Erik Liddell]

Since ICS, android has taken away the ability to override and/or completely 
disable system level navigation (ie, home, back, recent application and 
system settings pop up)   This is obviously to prevent malicious apps from 
essentially taking over the user's device.  But working in an industry 
where a great portion of our clients run retail environments that require 
tablets in a sort of kiosk mode so that customers can not exit the app, and 
go into settings ect. , it is proving difficult to push for them to go 
android vs iOs.   iOs 6 now offers a single app mode that allows the user 
to put a password on the device and once in an app lock it in that app so 
that the user can not exit the app unless they hit the home button three 
times and enter a password.  Does android have any plans to do something 
like this or am i missing something?

[android-developers] How to Create Custom Firmware for Android Device?

[erik wagner]

Hi,
I know this is a bit open ended but I am having a hard time finding 
something detailed and would appreciate any 'go here' that anyone could 
provide.  I have seen various instances on messages and posts advising 
people that they cannot do a certain action and would need to create their 
own version of the firmware to accomplish what they're asking.  Is there 
any detailed steps on how to do this?  I have gotten bits and pieces but 
not anything in any one place and definitely some contradictory information.
Thanks in advance for any help

[android-developers] Re: urgent - how to include existing c++ code into Android

[Erik]

The code you create with JNI can call into your c++ classes.

[android-developers] bug: emulator-x86 + kvm triggers an endless loop in qemu-setup.c

[Erik Nijkamp]

Hello folks,

we are experiencing a strange behavior while booting kvm-accelerated ICS 
image on some linux machines (both ubuntu  debian):

emulator-x86 -verbose -show-kernel -avd x86_4_0_3 -no-window -qemu 
-enable-kvm


The resulting log freezes after:

emulator: ping program: /opt/android-sdk-linux/tools/ddms


Therefore, we looked into the source code of the qemu / android emulator 
and stumbled over:

qemu-setup.c - android_emulation_setup(...)

if (path_exists(tmp)) {
...

/* disable SIGALRM for the fork(), the periodic signal seems to

* interefere badly with the fork() implementation on Linux running

* under VMWare.

*/

BEGIN_NOSIGALRM

pid = fork();

if (pid == 0) {

int fd = open(/dev/null, O_WRONLY);

dup2(fd, 1);

dup2(fd, 2);

execl( tmp, _ANDROID_PING_PROGRAM, ping, emulator, VERSION_STRING, NULL 
);

}

END_NOSIGALRM

} 



We are pretty certain that the codes hangs while invoking fork().

Firing strace 

strace emulator-x86 -verbose -show-kernel -avd x86_4_0_3 -no-window -qemu 
-enable-kvm


spits out an endless continuation of 

clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, 
child_tidptr=0) = ? ERESTARTNOINTR (To be restarted) 
--- SIGIO (I/O possible) @ 0 (0) --- 
clock_gettime(CLOCK_MONOTONIC, {55232, 717872152}) = 0 sigreturn() = 120 
--- SIGIO (I/O possible) @ 0 (0) --- 
clock_gettime(CLOCK_MONOTONIC, {55232, 719018162}) = 0 sigreturn() = 120 
--- SIGIO (I/O possible) @ 0 (0) --- 
clock_gettime(CLOCK_MONOTONIC, {55232, 719310431}) = 0 sigreturn() = 120 
clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, 
child_tidptr=0) = ? ERESTARTNOINTR (To be restarted) 



As a temporary workaround, the branch of code in qemu-setup.c triggering 
the fork() can be avoided by renaming the ping program (namely ddms) by

mv tools/ddms tools/ddms.fork.fix


However, we would like to avoid this hack in a productive system.


Any clues why the fork() in combinations with KVM keeps hanging?


Thanks so much!

[android-developers] Re: RelativeLayout problems

[Erik]

I think you're overriding the original layout params when you set the new 
one. Instead, get the view's layout params, change the width and height, 
and then set them back.

Though you may want to try using a LinearLayout and weight, which would do 
the layout for you.

 I'm working on some test code, just playing around with some image 
 processing methods, and this display may well end up being used in 
 an app for image processing.  The layout uses a RelativeLayout,

   ImageView

  android:scaleType=fitXY

  android:scaleType=fitXY 
  android:adjustViewBounds=true 
  android:layout_alignParentTop=true 
  android:layout_toRightOf=@id/originalView 
  android:layout_width=wrap_content 
  android:layout_height=wrap_content 
   / 

 and after a SeekBar and its two TextViews, which work fine, a ListView, 
 which is also fine: 

   ListView 
  android:id=@+id/filterList 
  android:textSize=22sp 
  android:layout_alignParentTop=true 
  android:layout_alignParentRight=true 
  android:layout_height=fill_parent 
  android:layout_width=300dp 
   /ListView 

 ---  CUT HERE  --- 

 Note that in the layout, the second (filtered) ImageView 
 is configured to align to the right of the original, and on the 
 top of the display. 

 I want to make this right, from the beginning, in case I do use 
 this layout for image processing (or at least, the final version 
 of it---it's not finished yet).  To do that, I plan on scaling 
 the two ImageViews (which, in turn, will scale the images inside, 
 as I'm using fitXY for the scaling method for the ImageViews). 
 I'm trying to scale these to equal fractions of the remaining 
 screen width (orientation set to landscape) after the ListView 
 on the far right.  If I hard-code the ImaveView widths for my 
 tablet, it works fine.  If I try to resize these from Java, 
 the two ImageViews, which are supposed to be side by side, end 
 up with the filtered (result) ImageView ON TOP of the one for 
 the original image.  This is definitely not what I'm trying to 
 do. 

 This is the code to resize the ImageViews: 

// original is a reduced-size copy of the real original bitmap 
int oiw = (float) original.getWidth(); 
int oih = (float) original.getHeight(); 

// Scale the two ImageViews relative to the display size, maintaining 
// the correct aspect ratio.  The ListView on the right of these is 
// 300dp wide, and I leave room for padding 

int iw = (int) ((dw - 340) / 2); 
int ih = (int) (iw * (float)(oih/oiw)); 

// and these are the lines I suspect are causing the error 
// 
origView.setLayoutParams(new RelativeLayout.LayoutParams(iw, ih)); 
filtView.setLayoutParams(new RelativeLayout.LayoutParams(iw, ih)); 

 Again, without the above re-sizing from Java (and the ImageView sizes 
 hard-coded in XML), the layout works fine. 

 I'm assuming that the problem is something I'm doing, and not a bug 
 in RelativeLayout itself (obviously...).  But whatever the problem 
 is, I can't see it, and have yet to find any reference that gives 
 me any kind of a hint as to what I'm doing wrong. 

 Can anyone here see what's wrong?  If so, how would I fix it? 

 Oh, as a side note:  when I tried the above code with an intermediate 
 step (calculate the aspect ratio BEFORE using it in the calculation 
 for re-sizing, as follows (with the original image width, oiw, and 
 height, either ints or floats...casting every calculation to float), 
 I get the same result either way: 

float aspect = (float) oih/oiw; 

 (yes, technically, that's 1/aspect ratio ... it's for the math that 
 follows to get the new height from the new width).  No matter what, 
 it ends up being 0.0 (should be 0.75 for the test image in use).  Put 
 that inline as above, and it works.  Apparently, Android doesn't 
 know that (float) 2/3 is 0.666 (ad infinitum), NOT 0.0  The 
 same happens if the two original dimensions are both floats. 


 Btw, the layout should look something like this: 

Top of displayt:  ImageView   ImageView ListView 

 Below that:   Filter Level (list continued) 
 Below that:   Seekbar - Value  (list continued) 

 Below that:   Red  (list continued) 
 Below that:   Seekbar - Value  (list continued

MMS messages can only be sent or received over a cellular connection. So

 When I click on it, the conversation thread opens up and I am able to

 Is this something that is normal on emulator, or should I be able to

 I can see that my Mms application code was built, but I don't see any

 Does anybody have an idea of what am I doing wrong?

[android-developers] Giving your emulator a boost: Android ICS x86 system-image available

[Erik Nijkamp]

Hey folks,

we (a mobile testing startup in Berlin) had some trouble regarding the poor 
Android ICS performance running in the ARM-specific SDK emulator.

Therefore, we've compiled Intels x86 Kernel for the Goldfish platform and 
Android 4.0.3 from ASOP soucres.
If you are interested, the ICS system-image which is compatible with the 
emulator-x86 and a very short installation guide can be found here:

http://blog.testobject.org/2012/04/giving-your-android-emulator-boost.html

We hope this gives your development speed a boost.

Any feedback is highly appreciated!

Thanks guys

[android-developers] Re: Giving your emulator a boost: Android ICS x86 system-image available

[Erik Nijkamp]

Hey Anuj,

according to [1] KVM on Ubuntu is equivalent to the HAXM hypervisor on 
Windows or Mac. So, yes, we do use hardware-assisted acceleration.

I don't have a Windows nor Mac OS at hand, but I bet the system-image would 
also work with HAXM.

Maybe you could give it a try?

Best,
 Erik

Unfortunately there doesn't seem to be a way to do what you want to do. The

phone number and some data.

 If that's the case, then you've written the intent wrong.

 However.  If you want to artificially impose the constraint of using a
 specific messenger, you can always check if the intent will succeed
 and fall back to a more generic intent otherwise, by checking to see
 if there's anyone registered to receive it.

  In general, Android promotes the idea of letting the user decide

  Yes, I understand now that the package may not be there in a

  Is there a way to find the default messaging application or the

  You don't want to do this... Not all phones will have the stock

 android apps

  Also, there are a lot of 3rd party apps out there that handle 
 sms/mms...
  If a user has installed a 3rd party app then they probably don't 
 want to be
  tied down to the one that came on the device.
 
 
  but it is showing a chooser for the mms intent to my friend. I am 
 not
  creating a chooser anywhere
 
  If that is the case then what is most likely happening is that your
  friend has more than one sms/mms app on the device.  You probably 
 also will
  notice that the chooser has a checkbox that, if checked, will make 
 their

[android-developers] Re: How can I send MMS via android app without moving to InBox Messages ?

[Erik]

In order to send an MMS, you would need to connect to the network's MMSC 
server. The network will only allow approved apps to do that, and in most 
cases the only approved app is the messaging app that came with the phone. 
So what you want to do is pretty much impossible.

[android-developers] ConnMan's Corresponding Component in Android

Dear All,

As you know, the Connection Manager (ConnMan) project provides a
daemon for managing internet connections within embedded devices
running the Linux operating system. --- http://connman.net/about.

So I'd like to know the corresponding component in Android, which does
the same work as ConnMan? Anyone know this? Or give me some links,
because I googled, but no useful infomation.

Thanks.

[android-developers] Re: Get MMS Info.

[Erik]

My guess is that your service is running before the native messaging app 
has a chance to add the message to the content provider. Try removing the 
priority from the intent filter.

Re: [android-developers] Re: Data written to SQLite database not immediately available

[Erik]

The threads use the content provider. The content provider's insert() 
method gets a database from the SQLiteOpenHelper each time.

I'll add that the content provider we're using is a modified version of 
Google's telephony content provider. We've been able to duplicate this 
behavior with the actual telephony provider on a shipping phone.

[android-developers] Data written to SQLite database not immediately available

[Erik]

My app has a content provider which stores its data in a SQLite db. I have 
a thread which is busy inserting rows into this content provider. I have 
another thread which inserts some rows into the content provider and then 
signals the first thread. When the first thread sees the signal, it stops 
inserting and queries for the data the other thread inserted. But what I'm 
finding is that often the cursor the query returns doesn't contain all of 
the rows the other thread inserted. If I sleep the thread for a second and 
query again, then all the rows are there.

It seems like the database is reporting that it has successfully stored the 
data, but it hasn't been flushed to the backing store yet. And the query 
that happens shortly after doesn't see the data that is waiting to be 
flushed.

Has anyone else seen this problem? Is this a bug in SQLite? Any suggestions 
on how to deal with it?

[android-developers] Re: Distribute banned app outside Android Market with donation app in Market

Google thought the app was sexually explicit and banned it. I may

the next best.

[android-developers] Distribute banned app outside Android Market with donation app in Market

[Erik]

A few days ago my hit app got banned from Android Market and now I´m
looking for a different setup.

My planned setup:
- Empty paid donation app inside the Market.
- Free app outside Market with link to my donation app.

First, am I allowed to have a empty donation app? There are some out
there but that´s no guarantee.

Does anyone know if Google will have a problem with the fact that they
are supporting my banned app through my donation app? I guess, for
example a porn site cannot have a payment option with an empty app.

I read the agreements and found nothing specific that would prohibit
me.

I sent this question to Google but I don´t expect a quick reply.

Bottom line:
Will my donation app get banned?

[android-developers] Changing the icon for the All Apps Button

Hi,
I am looking to actually replace the 'All Apps' button on the Android
home screen.  I know there is the Home sample app, as near as I can
tell (and please correct me if I'm wrong) it overlays a separate home
button on top of the existing one - instead of actually replacing it.
Is there a way to actually replace the All Apps icon on the Android
home screen?
Sorry if this is a duplicate question, searching for 'all apps button'
returns a dizzying array of non-pertinent results.
Thanks,
Erik Wagner

 No, short of hacking the app on a rooted phone. Bear in mind that
 there is no single Android home screen -- there are probably a few
 dozen in use on production hardware and uncounted home screens you can
 download from the Android Market.

 You can create your own home screen app (see the sample app you
 mention). Users will then have a choice of running your app or the
 built-in one when they press HOME. If they make your app the default,
 they will go to your app exclusively when the press HOME, until they
 remove your app or launch in safe mode.

[android-developers] sqlite help

Hi,
I am wondering if anyone has a simple SQLite app/example they can
point to, provide or whatever.  Just basically looking for an example
that will connect to a database, and add or remove a record.  Been
trying to sift through the searchable dictionary example and currently
not having much luck getting to the barebone essentials.
Failing an example, if anyone could provide a rough outline or what to
do that would be extremely helpful as well.
The example/outline doesn't need to be overly involved, just looking
for what amounts to a Hello SQLite app.
Thanks for any help/advice

 I recommend Mark's books for leaning Android dev period. They are
 fantastic. I also recommend Android Application Development For
 Dummies by Donn Felker. The SQLLite section is simple and easy to
 understand and learn. I started down the SQLLite road after reading
 this tutorial:http://www.screaming-penguin.com/node/7742.

 Without knowing your level of development expertise, it's hard to give
 you a tutorial to fit your needs.

[android-developers] Debugging library projects with ADT 14

[Erik]

I've got my library project converted to the new ADT 14 format, but I've run 
into an annoyance. When I hit a break point in my library project code, the 
Eclipse debugger opens up the (read-only) copy of the file's source from the 
JAR, and not the original source file. So I end up with two tabs, one being 
the original source with the break points marked, and the other the source 
where I'm stepping through the code. Does anyone know how to get Eclipse to 
do the stepping in the original file?

On a related note, is there any way to get Eclipse to debug the associated 
application when I hit F11 in a library source file?

Thanks,
Erik

[android-developers] Getting info from a calling activity advice

[erik wagner]

Hi,
I'm trying to do something where I have an activity that needs to call
another activity.  I use the startActivityForResult and pass it a
integer as the second parameter.  I know I can check for that
information after the second activity is done but my question is; is
there a way I can know what the integer value is when starting the
second activity?
So, I have
startActivityForResult(myIntent, 1);
When the activity described by myIntent is started is there a way I
can grab the 1 value and do something with it?  If not, can anyone
provide some advice on how to get a value from a calling activity to
the called activity?
Thanks in advance.

[android-developers] return values from preferences with getString

[erik wagner]

Hi,
I'm having a bit of a problem with the return values from
preferences.getString.  The value that I'm getting returned doesn't
seem to be correct.
This snippet will not evaluate correctly (i'm omitting the
toast.length_long ending since it formats squirrelly).  This always
goes to the else (i.e. 'nothing') condition.  There are only two
possible values (Two and Four).

String strTemp=prefs.getString(listPlayers, );
if (strTemp==Two) {
  Toast.makeText(WarGamePlay.this, two?,
} else if (strTemp==Four) {
  Toast.makeText(WarGamePlay.this, four?,
} else {
  Toast.makeText(WarGamePlay.this, nothing?,
}

If i exchange the prefs.getString with just...

String strTemp=Two;

then that correctly goes to the first condition in the if/else tree.

What am I missing?  I have checked the values coming back from the
prefs.getString and there are no leading/trailing spaces or anything

Any help on this would be appreciated.  Thanks in advance.

[android-developers] Re: return values from preferences with getString

[erik wagner]

Thanks very much!  I have to say though my (ignorant) questions are
not over.  I am ultra newbie on Java and am not sure how to write a
(working) Equals method.
This is the body of the Equals I wrote
public boolean equals(String strTemp) {
  SharedPreferences
prefs=PreferenceManager.getDefaultSharedPreferences(this);
  if (strTemp instanceof String) {
String strP1 = prefs.getString(listPlayers, );
if (this.equals(strP1)) return true;
  }
  return false;
}

in the code i'm trying to do something along the lines of
if ((equals(Two) {
// blah blah
}

I know this is a basic-really-should-know-how-to question but I'm kind
of flailing on the whole thing.  Thanks.

  Hi,

  seem to be correct.
  This snippet will not evaluate correctly (i'm omitting the
  toast.length_long ending since it formats squirrelly).  This always
  goes to the else (i.e. 'nothing') condition.  There are only two
  possible values (Two and Four).

  String strTemp=prefs.getString(listPlayers, );
  if (strTemp==Two) {
       Toast.makeText(WarGamePlay.this, two?,
  } else if (strTemp==Four) {
       Toast.makeText(WarGamePlay.this, four?,
  } else {
       Toast.makeText(WarGamePlay.this, nothing?,
  }

  If i exchange the prefs.getString with just...

  String strTemp=Two;

  then that correctly goes to the first condition in the if/else tree.

  What am I missing?  I have checked the values coming back from the
  prefs.getString and there are no leading/trailing spaces or anything
  else visually wrong that I can see with the value.
  Any help on this would be appreciated.  Thanks in advance.

 I heartily encourage you to learn Java *before* attempting to get into
 Android development, simply because most of the Java educational
 materials out there are designed for non-Android environments.

  This is the body of the Equals I wrote
  public boolean equals(String strTemp) {
       SharedPreferences
  prefs=PreferenceManager.getDefaultSharedPreferences(this);
       if (strTemp instanceof String) {
             String strP1 = prefs.getString(listPlayers, );

       }
       return false;
  }

 There is no point in your instanceof test, as Java is strongly typed,
 so it will always be a String. Also, I didn't tell you to *write* an
 equals() method, but to *use* the equals() method, as you did inside
 your own equals() method.

I apologize that the code appeared to be/was unformatted, it looked
fine on my end.

Thanks for the tip.  That is exactly what I was trying to hodgepodge

 I didn't look over your giant blob of foreign, unformatted code, but you
 should not neither either a spinner or edit text in a preference actiivty,
 unless you have your terms mixed up.

 All you should really need is a list 
 preference.http://developer.android.com/reference/android/preference/ListPrefere...

[android-developers] help with spinners from preferences

[erik wagner]

Hi,
I have a preference screen where a edit text brings up a spinner, the
result from the spinner needs to get to the edit text on the
preference screen and the value from the edit text needs to then get
back to the main activity.  I can get the value from a straight edit
text to the main activity but I cannot figure out how to get the
spinner choice to the edit field.
(disclaimer, the bulk of this is from an example project that I am
trying to use to learn how to do this).
The relevant porton of the main.xml
TableRow
TextView
android:text=Edit TEXT:
android:paddingRight=5dip/
TextView android:id=@+id/edittext/
/TableRow

I have a preferences.xml in the /res/xml folder...
PreferenceScreen
xmlns:android=http://schemas.android.com/apk/res/android;
EditTextPreference
android:key=edit_text
android:title=Edit Text Preference
android:dialogLayout=@layout/spinner
android:summary=What to do?/
/PreferenceScreen

I also have a spinner.xml in the /layout folder
?xml version=1.0 encoding=utf-8?
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:orientation=vertical
android:layout_width=fill_parent
android:layout_height=fill_parent

Spinner
android:id=@+id/spinner
android:layout_width=fill_parent
android:layout_height=wrap_content
android:width=200dp
android:entries=@array/edit_text_array
/
/LinearLayout

There are two activities.  The first is PrefsActivity
package com.Prefs;

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;

public class PrefsActivity extends Activity {
/** Called when the activity is first created. */
private static final int EDIT_ID = Menu.FIRST+3;

private TextView check_box=null;
private TextView edit_text=null;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
check_box=(TextView) findViewById(R.id.checkbox1);
edit_text=(TextView) findViewById(R.id.edittext);

}

public void onResume() {
super.onResume();

SharedPreferences
prefs=PreferenceManager.getDefaultSharedPreferences(this);
check_box.setText(new Boolean(prefs.getBoolean(check_box,
false)).toString());
edit_text.setText(prefs.getString(edit_text, ));
//spinner.setText(prefs.getString(spinner, ));
}

public boolean onCreateOptionsMenu(Menu menu) {
menu.add(Menu.NONE, EDIT_ID, Menu.NONE, Edit Prefs)
.setIcon(R.drawable.icon)
.setAlphabeticShortcut('e');

return(super.onCreateOptionsMenu(menu));
}

public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case EDIT_ID:
startActivity(new Intent(this, EditPreferences.class));
return(true);
}
return(super.onOptionsItemSelected(item));
}
}

and finally the EditPreferences activity.
package com.Prefs;


import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceActivity;
import android.preference.PreferenceManager;
import android.widget.TextView;

public class EditPreferences extends PreferenceActivity {
private TextView spinner=null;
private TextView edit_text=null;
@Override

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
spinner=(TextView) findViewById(R.id.spinner);
addPreferencesFromResource(R.xml.preferences);

}

public void onResume() {
super.onResume();
}
}

What I was thinking was that the spinner needed to feed the result to
the edittext on the preferences before the edittext on the preferences
could feed it to the one on the PrefsActivity activity.
Long story short, what am I doing wrong and what should I do on this?
I'm a little brained out on this after staring at it and trying
everything my limited understanding could think of.
Thanks in advance.

[android-developers] Advice on getting data from one activity to another

[erik wagner]

Hi, I guess this is more of a design with more than a little 'how do
i' mixed in question.  I have two activities (thus far), a main page
and an options page.  On the options page I set an option that I need
to 'see' on the main page (as well as on subsequent other activites).
What is the 'best' way to do this?  Global variables are a no-no and a
bit of a pain to do as I understand it.  How can I do this?  Perhaps
just point me in the direction of a dev article on the subject though
I couldn't find anything on point.  At least at that point I can then
move on to more detailed how-to questions.  Thanks again for all the
help on my various newbie questions.

 Use SharedPreferences and an OnSharedPreferenceChangeListener.

[android-developers] reading choices from spinners

[erik wagner]

Hi all, I have a very simple game that I'm trying to do for learning
purposes.  One of the options is selecting the number of players (2-4)
via a spinner.  When a choice is made from the spinner I am moving the
value to a string and then using that string in a series of if/else if
statements to (eventually) handle the option.  I am running into the
problem where the condition that (to me) seems like it should be true
is evaluating to false.
If I select Two, the value moved to the variable is Two but the
check for the variable == Two isn't getting hit.
(hope that was all clear, backstory may not be needed but better safe
than vague).  Anyway, the spinner's OnSelectedItemListener...

public class MyPlayerOnItemSelectedListener implements
OnItemSelectedListener {
public void onItemSelected(AdapterView? parent, View view, int
pos, long id) {
String strResult;
strResult = parent.getItemAtPosition(pos).toString();
if (strResult == Two) {
Toast.makeText(parent.getContext(), this is the result 
when
one is selected, Toast.LENGTH_LONG).show();
} else if (strResult == Three) {
Toast.makeText(parent.getContext(), three players / +
strResult + /, Toast.LENGTH_LONG).show();
} else if (strResult == Four) {
Toast.makeText(parent.getContext(), four,
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(parent.getContext(), something else / +
strResult + /, Toast.LENGTH_LONG).show();
}

}
public void onNothingSelected(AdapterView? parent) {

}
}

No matter what I select using this code the Toast shows as something
else / + what the value actually is + /.  i.e. if I chose 'Two' the
toast reads something else /Two/.
Any help would be greatly appreciated on this.  I'm certain it is
something very fundamental that I'm just missing.  Thanks in advance

[android-developers] Getting a second page to do anything

[erik wagner]

Hi,
This is I'm sure a very simple thing to do and I am just missing
something but I am just starting out.  I have the main view, which has
a button.  The button brings up a second view that is supposed to show
some toast message (or, in fact do anything).  I can get everything to
work on the first view, but nothing at all to work on the second.
first view (main.xml for the layout)
public class actvSecondPage extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

final Button btnToast = (Button) findViewById(R.id.btnToast);
btnToast.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Toast.makeText(actvSecondPage.this, this is some 
toast,
Toast.LENGTH_LONG).show();
}
});

final Button btnSecondPage = (Button)
findViewById(R.id.btnSecondPage);
btnSecondPage.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.second);
}
});
}
}

Second view (second.xml for the layout)
public class actvSecond extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);

Toast.makeText(actvSecond.this, this is some toast on the 
actual
second page., Toast.LENGTH_LONG).show();
};
}
the android.manifest.xml (in case i'm missing something there)
?xml version=1.0 encoding=utf-8?
manifest xmlns:android=http://schemas.android.com/apk/res/android;
  package=com.SecondPage
  android:versionCode=1
  android:versionName=1.0
uses-sdk android:minSdkVersion=3 /

application android:icon=@drawable/icon android:label=@string/
app_name
activity android:name=.actvSecondPage
  android:label=@string/app_name
intent-filter
action android:name=android.intent.action.MAIN /
category
android:name=android.intent.category.LAUNCHER /
/intent-filter
/activity

/application
/manifest

Can anyone help as to why what works in the first class does not in
the second?  Or, rather, that nothing at all works in the second
class?  Any help would be appreciated, thanks.

[android-developers] Hello Listview project

[erik wagner]

Hi to all,
I am very new to both java and android development so this is probably
a very simple question.  I have been going through the various 'hello'
tutorials on this site.  I've hit a snag on the 'Hello Listview' (this
one http://developer.android.com/resources/tutorials/views/hello-listview.html).
When trying to run it I get a fatal error and the debugger shows me
the following message of

Your content must have a ListView whose id attribute is
'android.R.id.list'

I've seen some similar things on various posts but could not find the
answer to; 1. where is this entry to be made (the
androidmanifest.xml?  the list.xml?) and 2. what the entry actually
should be.
Thanks in advance for any answers.

[android-developers] Re: Distance between devices

[Erik]

It's possible to use GPS to determine the distance between to receivers to 
that accuracy, but it involves one device getting the low-level GPS data 
from the other device and doing some processing on both sets of data. And I 
have no idea what data you actually need to perform that processing, or 
whether the device's NMEA strings contain that data.

[android-developers] Custom Font

[erik ryerson]

I'm having some trouble adding a custom font to skin.xml

Here is my code

I have this in the skins xml files

Code:

TextView android:id=@id/sender_phone_num
  android:textColor=#332f33/

So I added this to my main package

Code:

TextView tv=(TextView)findViewById(R.id.sender_phone_num);
Typeface face=Typeface.createFromAsset(getAssets(),
fonts/nokiafc22.ttf);
tv.setTypeface(face);

and placed the font in the assets/fonts folder

I must be missing something, because the font isn't changing in app

Any suggestions?

[android-developers] Re: APN for SMS/MMS

[Erik]

If you mean you can't contact the MMSC to download the MMS message, Verizon 
and Sprint will only let apps that are specially blessed do that. And that 
isn't going to happen for you.

Your best bet is to let the phone's native messaging client handle all of 
the MMS sending/receiving.

[android-developers] Multicast and WiFi tethering

[Erik H]

Hi,

I got an application that sends and receives UDP messages using a
MulticastSocket. It works fine between two phones when both are
connected to a normal WiFi AP (e.g., my WiFi at home). However, when
either device has WiFi tethering active and the other device is
connected to this network sending Multicast packages doesn't work
anymore. If I set-up a third device which has WiFi tethering enabled
and let the first two devices connect to this network it works as
expected between the two devices (however, the third device with
tethering active cannot receive or send Multicast packages).

My conclusion is that a device that has WiFi tethering enabled cannot
send or receive Multicast packages. Is this an expected behavior or
should I consider it a bug?

Thanks!

// Erik

[android-developers] Re: Sent SMS doesn't show up in the messaging app?

[Erik]

All messaging apps use the Telephony content provider to store messages. So 
you could insert() a message into the content://sms/ provider. It's not 
simple, you'll probably need to read through the code of the open source 
messaging app to figure out how to format the message.

Well, the messaging app my company wrote uses the Telephony content 
provider. Handcent SMS uses it, as does GO SMS. I'm guessing all the SMS 
backup apps out there back up the Telephony content provider.

If there's a phone out there that doesn't have this content provider, then 
the OP's app should be written to fail gracefully, but I think those will be 
few and far between.

[android-developers] Loading Bitmaps in native heap

[Erik R]

I'm working on a simple image manipulation app that requires opening
bitmaps at full resolution, which of course results in OutOfMemory
issues. I know that the short answer is to simply use less memory via
BitmapFactory's inSampleSize Option to downsample the bitmap, but for
this app I really would like to retain the full resolution for
editing. One solution I have been investigating is loading the bitmap
entirely on the native heap, after learning that the memory limitation
is only imposed within the Dalvik VM heap. A look into the Android
source code revealed that this is already the case... BitmapFactory
uses native methods to load a bitmap on the native heap, while
maintaining a reference to it on the VM heap. The issue then is that
it appears the native memory used by the bitmap is actually counted
against the available VM memory, when it really isn't there. A look
into the stock Camera and Gallery apps' source revealed that they get
around this by using an additional BitmapFactory Option,
inNativeAlloc. I was able to find this field in the Java code for
BitmapFactory:

 196  * Normally bitmap allocations count against the dalvik
heap, which
 197  * means they help trigger GCs when a lot have been
allocated. However,
 198  * in rare cases, the caller may want to allocate the
bitmap outside of
 199  * that heap. To request that, set inNativeAlloc to true.
In these
 200  * rare instances, it is solely up to the caller to
ensure that OOM is
 201  * managed explicitly by calling bitmap.recycle() as soon
as such a
 202  * bitmap is no longer needed.
 203  *
 204  * @hide pending API council approval
 205  */
 206 public boolean inNativeAlloc;

Are there any plans to unhide this field anytime soon?

[android-developers] Re: Is it impossible to move and merge text on an image

[Hans-Erik]

I forgot to say i need to save the image with the added text, like
merge into a new image.
I guess that complicates things.

Im investigating and can see that the Canvas class has the drawText
method.
drawText will write the text solid on the image.
So i guess using Canvas is the way to go.

@Miguel Morales thanks and sorry i forgot to say the text and image
must be merged together and two ImageView cannot do that i think.

@ThreKing Thanks for taking your time. Since I dont know back from
front in this project i cannot ask for specific if i don't know if the
Egg came before the chicken or wise verse.

 Well, simply do the saving when the user is finished moving the text or
 using the feature compose the image.
 The bitmap canvas supports basic things like drawing text.
 This doesn't complicate things.

yea you right i think, after playing around with this sample for 30
min
http://www.anddev.org/viewtopic.php?p=11603

Can replace one of the balls with text.
The question is how to input the text.
once the text is Inputed it can be moved but howto let user input
it.
Maybe longpress,, something

[android-developers] Rotating a fragment

[Erik]

I have an Activity with different layouts for portrait and landscape.
Since it has some complex state data I don't want to lose on rotation,
I'm listening for rotation config changes. In onConfigurationChanged()
I call setContentView() to rebuild the view hierarchy using the new
layout.

Now I'm converting the activity to use a Fragment. I want the Fragment
to behave just like the Activity, rebuilding the view hierarchy with
the new layout when it gets onConfigurationChanged(), but there
doesn't seem to be any way to change a Fragment's view after it's been
created. The only way seems to be to create a new Fragment, but then I
lose all the state data from the original Fragment.

Does anyone have any ideas on how to make this work?

[android-developers] list view: scrolling resizes the items in a weird way

[Erik]

Hi,

I have a problem with the list view and its items. When scrolling up/
down the listview I noticed that the items slightly resize(about one
pixel) and in my application it looks like ^. The divider between two
items should be one pixel high(used default android behavior), but
when scrolling the divider is sometimes 2 pixels or 0 pixels(not
visible). This is bad since it looks like the two items form one list
item.

Has anyone a solution for this weird resizing problem when scrolling
inside a listview?

My development device is the HTC Wildfire with firmware version 2.1-
update1. Emulator is set to:Android 2.1-update1, skin WVGA800 and
hw.lcd.density=240.

[android-developers] Re: EditText and auto-complete/correct

[Lars-Erik]

Actually I had the same problem and found the real solution.
autoText is a deprecated feature.
However looking more closely on the textAutoComplete function I
found that it states that the application will provide the correction
list itself.
In stead, just use the textAutoCorrect in android:inputType
without the textAutoComplete and it will work. Did for me, at
least!

so in the initial example of this thread you would use:

EditText android:id=@+id/alarmMemo
android:layout_width=fill_parent
android:layout_height=match_parent android:imeOptions=actionNone
android:inputType=text|textAutoCorrect|textShortMessage
android:maxLength=150/EditText

 I found the solution courtesy of a quick peek at the WordPress for
 Android app's resource files! The answer is to remove the
 android:inputType attribute and substitute it with
 android:autoText=true. Simple yet effective!

[android-developers] Re: Service or no service

[Hans-Erik]

That's quite interesting thanks TreKing.
That is one approach but dont think it will work for me.

On scenario is if 200 phones connect to my server wanting to send one
jpg to another phone.
200 messages would go out trough google notifying all phones there is
jpg package for them.
Google has Limitations in that C2DM about Google limits the number of
messages a sender sends in aggregate. Also possible lagging.

My initial naive thought was that all those 200 phones could have an
app installed that make a connection to me PC server and keep that
connection alive.

I'm searching for a best way to do do this. What would you do?

- Services are bad design and a user might think his battery get
drained
- Activity with AsyncTask is beautiful if android not killing the app
Hmmm (not sure there).
  One AsyncTask constantely listening for incoming and another
AsyncTask gets created when
  user send jpg. Can an AsyncTask live that long, Is it possible to
protect the AsyncTask
  from onCreate updates, orientationchanges?

 I guess if you have a significantly large user base, but I'm assuming that's
 not the case, or is it?

Im planing ahead, trying to learn what it takes to make and app like
that

 Is some lagging or some delay in the delivery of these messages
 completely unacceptable?

yes im playing with the ide since mail or sms is no instant

 What is so urgent about these messages that they *must* be received
 instantaneously?

That is a powerful features for a mobile app

 Perhaps give the user a poll interval or an option for manually refreshing
 the data, if it makes sense for your app.

no, that way the phone is never ready to receive .

 I would rethink what you're trying to accomplish and try to work within the
 restrictions imposed by mobile devices.

your right ofcorce, im new to android but not to Java so the
transition is
a bit painful

 You can certainly keep your AsyncTask alive between orientation changes -
 but only as long as the user keeps your app in focus as the current
 Activity. Once you get put in the background you're subject to being killed.

AsyncTask out the door, Services welcome in.

 There's really no such thing as keeping a connection alive. Your process
 can and will be killed at some point, if not by the system then explicitly
 by the user.

In my Desire phone i see both fring and Google mssagin always running
Read some about a service being Sticky

I read elsewhere that a service can be started with a Brodcastcmmand
http://stackoverflow.com/questions/4468006/can-i-start-a-service-without-activity-or-receiver

cant wrap my head around the code implementation here.
after reading many questions here and elsewhere about this.
I think the method is:
- an apk file which contains a Service an activity and a
BroadcastReceiver Class.
- action.BOOT_COMPLETED will start only my Service, not the Activity.
  The user can from Main Launcher start Activity for in app settings
and I Bind
  to Service and Unbind when done

Yea will try this tomorrow after work.

I look at your TreKing app. Im impressed nice work

[android-developers] Service or no service

[Hans-Erik]

after reading the article
http://www.androidguys.com/2009/09/09/diamonds-are-forever-services-are-not/

I want to ask about creating an Android app that need to run always!
The app is an ftp server listening for my PC client to send pictures.
The sending can occur anytime so the Android server MUST run

Here's the question:

From the article above a read
Service can be killed by the user and the android system.
The can fall asleep when the device falls asleep.

What about Activity´s,  can i do this simply trough an Activity?
If my activity create a thread for the server to run in.
When a client connect, the thread will receive the picture(s)
and notify Activity and then thread continue Listen.

What are the considerations here?

[android-developers] Re: Android apps deployed from Eclipse don't take up full screen

A screenshot will also help greatly if you can post one.

It sounds like you might be creating a Dialog instead of an Activity.
If you are creating an Activity, you may have somehow specified a non-
fullscreen theme for it in the manifest XML.

 I'm a relative Android newbie here.  At first, I thought it was just a
 problem with my code, but I've since discovered that this problem
 applies even to the default, unmodified app templates I can choose
 from when creating a project in Eclipse.  Every app only takes up a
 fraction of the screen.  Here's my layout for an example, but again,
 it affects all of them:

 ?xml version=1.0 encoding=utf-8?

 /RelativeLayout

 The specified screen resolution is, as in the droid, 854x480. It shows
 up in the emulator in horizontal or vertical mode. The map starts
 about a third of the way from the left and ends about a third of the
 way from the right. It starts at the top and ends about a third of the
 way from the bottom of the screen. I have no clue why that would
 happen, as I specified fill_parent.

 I've tried a variety of things. I switched to a linearlayout, as one
 page I saw recommended. I tried spelling out absolute layout widths. I
 tried all sorts of stuff. The map stubbornly remains surrounded by
 black on all sides.  One thing I noticed was that when I specified
 widths and heights that were really large, way bigger than the screen,
 the map showed up as pure white instead of as a map. But it still had
 the black all around the map as described above.  The title bar
 likewise is truncated by the black bars on either side and only takes
 up 1/3 of the width, whether in landscape or portrait mode.

 The apps that come by default on the emulator take up the fullscreen,
 but everything I install from Eclipse does not.

 I posted this over on Stack Overflow but got no responses, so I
 thought I'd try here.  Thanks for any help you can give.

[android-developers] Re: Query regarding Intent.get Extras.

[Erik R]

Snippets pulled from Android source:

#1 - All the putExtra methods instantiate a new Bundle when the Intent
receives its first extra, to contain all extras going into it.

public Intent putExtra(String name, Bundle value) {
if (mExtras == null) {
mExtras = new Bundle();
}
mExtras.putBundle(name, value);
return this;
}

#2 - Looks to be the case. A new instance of Bundle is created with
the contained extras.

public Bundle getExtras() {
 return (mExtras != null)
 ? new Bundle(mExtras)
 : null;
 }

[android-developers] ActivityInstrumentationTestCase2 private static final Object is null when running test suite?

[Erik]

Hi,

I have a problem where a private static final Object LOCK = new
Object(); is null at some point when running my TCs.

Obviously if i remove the static status and initialize it in the setUp
method, this problem disappears; I just wanted to know if this is
supposed to happen? The problem also disappears if i move the static
initialization to a Utility class and make it public.

The null pointer exception is received in a callback method when i try
to do a synchronized(LOCK) lock on the object.

Any pointers?

Thanks.

[android-developers] Null canvas being passed to onDraw(Canvas canvas)

[Erik]

I have two bug reports now in my publisher console, and the both are
Null Pointer Exceptions from onDraw, and result from a null canvas
object being passed into the method.   I've searched and not found any
information on why this may be happening.  Anyone have ideas? Or any
ideas on how to gracefully handle a null canvas being passed in?
Wondering if I should return from the method or attempt to exit the
app gracefully?

Both errors were on the droid platform.

[android-developers] Offscreen drawing of a View

[Erik H]

Hi,

I'm having a small problem with drawing a View offscreen to a Bitmap.

The View is created using  LayoutInflater.inflate(int resource,
ViewGroup root) with null passed to the root parameter. The View has a
fixed size (200x180 pixels). I can create a Bitmap for this View
either by using the method View.getDrawingCache() or by calling
View.draw(Canvas canvas) using a Canvas that in turn has a backing
Bitmap.

This works fine if the View doesn't change after the inflate. However,
if I have a TextView inside my View that I will update, the size of
the TextView is never updated regardless of what method I call on the
View (requestLayout(), forceLayout() invalidate() etc.). If I display
the View on screen directly, everything works fine (sizes are updated
as needed, etc.).

What is the correct way of drawing Views off screen and being able to
update their layout when needed?

[android-developers] Re: Offscreen drawing of a View

[Erik H]

Never mind. I managed to solve it myself. Hopefully, this is also the
right way of doing it. :)

I need to manually call View.measure() and View.layout() on the
inflated view every time I change something. The tricky part is that
the measure() method needs values taken from
View.MeasureSpec.makeMeasureSpec(), like this;

int measuredWidth = View.MeasureSpec.makeMeasureSpec(bitmapWidth,
View.MeasureSpec.EXACTLY);
int measuredHeight = View.MeasureSpec.makeMeasureSpec(bitmapHeight,
View.MeasureSpec.EXACTLY);
offscreenView.measure(measuredWidth, measuredHeight);
offscreenView.layout(0, 0, offscreenView.getMeasuredWidth(),
offscreenView.getMeasuredHeight());

Also, I must use a Canvas backed by a Bitmap when drawing. Using the
drawing cache doesn't seem to work well.

Please correct me if I'm doing something wrong here. Hope this can
help the rest of you otherwise. :)

[android-developers] Re: Pausing Live Wallpapers

[Erik R]

Thanks Romain,
FYI the app in question relies heavily upon the gestures API that you
developed. Nice work! I'd be willing to help out with documentation if
help is needed in that area - it is a bit lacking at the moment,
especially with regard to multiple-stroke gesture recognition.

The workaround that I've implemented on this is to simply use the
wallpaper-only theme as opposed to fully translucent. Achieves a
similar enough effect, and for some reason does not slow it down as
much.

Hello Devs,
I have the problem that even though the activities starts i cannot get
the data back from the filebrowser.java. I am not getting any errors
except the line begining with the *. The error is code is never used
locally. I have also checked the filbrowser and it does give an output
with the code aDirectory.getAbsolutePath().toString() so the issue
is somewhere in the transfer. Code is below:

Main.java
[
//Code + imports above
   public static final int ACTION_PICK_FILE = 0;

   //Code above is outside the method body.

button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
Intent filebintent = new
Intent(arg0.getContext(),Filebrowser.class);
startActivityForResult(filebintent, ACTION_PICK_FILE);
}
*protected void onActivityResult(int requestCode, int
resultCode, Intent filebintent)
{
 switch(requestCode)
 {
 case ACTION_PICK_FILE:
 if (resultCode == RESULT_OK)
 {
Bundle bundle = filebintent.getExtras();
String select1 = bundle.getString(Selected1);
String path1 = select1.getBytes().toString();
System.out.println(select1); //Check if there is an
output.
System.out.println(path1); //Check if there is an

 }
 break;
 }
}

An important part of creating an android application is making the gui

of what I am looking for is something like this

what other interesting styles does exist. The eclipse layout xml

[android-developers] Re: App name/icon problems on Hero after reboot

[Erik Bryan]

For what it's worth, I stopped using the Sense UI in favor of the
default home, but did not wipe everything first. Upon entering the
default home for the first time, all my apps had the right names/
icons. After resetting though, they were displaying in their mangled
state in the default home. Does that tell you guys anything? If the
apps are displaying incorrectly in the default home, does that mean
that HTC has changed the packages themselves, or is it just an issue
with how they are displayed?

I have the same build number that Justin mentioned above.

 Basically you wipe the phone  sd card, reinitialize the phone, then

 do this.

 Just a FYI and further evidence that HTC has some issues they may or may not

[android-developers] Fail to launch the SDK 2.0 tool on OS X

I downloaded the SDK 2.0 toolkit and tried to launch the android tool

following output:

$ ./android-sdk-mac/tools/android
Starting Android SDK and AVD Manager
No command line parameters provided, launching UI.
See 'android --help' for operations from the command line.

That's it. Nothing happens, no UI appears or any processes are started
(check with ps, but there is no new java process).

I'm running this on Mac OS X 10.5.8. The previous SDK s runs fine.

[android-developers] Re: App name/icon problems on Hero after reboot

[Erik Bryan]

I just installed Light Racer on my Sprint Hero. Had never installed it
before. Rebooted and it was fine, still named Light Racer, still with
the same icon. I assume this is because you updated Light Racer and I
had never installed it before.

However, I am having this problem with several other apps, which
variously use their full name (com.x...) or their icon changes to
something weird:

Where (icon)
Quick Settings (icon)
ASTRO (icon)
Coin Flip (name)
Meebo (name)
Handcent Sms (icon)

Reinstalling any of these fixes the problem, which will then come back
after a reboot.

Let me know if more data from me would be helpful.

 Justin,

 Did the app name say Light Racer or net.rbgrn.lightracer after the

 I had a version out that used a raw string as the app label in the

 that it's the correct name and not the package name, then that's
 certainly one of the bugs right there.  People that have installed it
 when it had the raw string app label never seem to get it fixed.  Even
 updating to the one you claim works doesn't work for them.  It's like
 once it's broken on the device, the cached data never goes away.

 That makes we wonder if there is a way to clear data on one of the
 system apps that will reset that cache...

[android-developers] Design guidelines question; Services vs. Intent broadcasts.

[Erik H]

I'm writing an application that consists of a background Service and
one or several Activities acting as UI towards this. There will most
likely be several different UIs for this service that will installed
later on, like custom widgets or UIs. The question is how to solve
this in the most efficient way.

Is it better to only use Intents for communication between UI and
Service (sending control commands with Intents from the UI and
listening for Intents from the Service for state and data updates) or
should I prefer using IPC communication (AIDL - Java Stub, binding to
the service etc..)? Since the UI might be started long after the
service is started, I would either need to use sticky intents to
signal current state, or have a very frequent intent sent by the
service if choose to go with the Intent-based design. Which one would
be the preferred way in that case?

I've read that sticky intents are much more resource consuming than
normal intents, but are intents more consuming than IPC directly
towards the service?

Also, is really an AIDL the right way to allow third-party
integration? Intents sounds better, since they are also asynchronous.

Please advice. :)

Thanks!

[android-developers] Re: Design guidelines question; Services vs. Intent broadcasts.

[Erik Hellman]

On Jul 6, 1:28 pm, Mike Hearn mh.in.engl...@gmail.com wrote:
 First and most important question - do you really need a service at
 all? Many apps use services but don't actually need to run all the
 time. Using a service is like a tax on your user. It's currently
 invisible but it won't always be that way: expect your users to start
 asking questions at some point if/when Android makes resource
 consumption of apps more visible.

Yes. I absolutely need a background service since I'm doing something
similar to a music player. :)

 Now how to sync state between the activities and the services.

 Remember that a service is just an object representing a lifecycle
 construct. It exists in the same process that your activities do, so
 they can communicate in the same way any two Java objects would
 communicate - via direct method calls, for instance. It's perfectly OK
 to use the local service idiom that is shown in the API samples to
 bind to a service and then cast the result to the object itself. Or if
 started using an intent, you can just stuff a reference to this into
 a static field.

 As to using intents, you don't have to do this. You can just keep
 track of what the service is meant to do in a file, a database, or
 whatever else is convenient.

I agree totally, but my problem is that my service will most likely be
used by other applications. There could be three (or more) completely
different applications using the service at the same time (a standard
UI doing one type of visualization and another app doing a different
visualization and a homescreen widget, all in different .apk).

So the question remains. If I need to support third-party integration,
is a service (published as an AIDL file) better than Intents? And if
using Intents, is it better to use sticky intent or should I send very
frequent normal broadcast intents from the service to signal its
state?

Thanks,
Erik
