[android-developers] Re: Geo command

[Mark Murphy]

 Anyone can help me on this?

 I installed android sdk 1.5, but in no where I can find the geo
 command. Where should I get one?

You need to telnet into the emulator:

telnet localhost 5554

And there you can run the geo command:

geo fix [lon] [lat]

[android-developers] Re: aidl remote service call namespace question

[Dianne Hackborn]

For the second question, you'll either want to define an abstract action in
an intent-filter for the service and use that as the intent you bind to
(typically the action is the name of the desired interface for binding to
services), or create an explicit ComponentName with the package name + class
name of the service being bound to and provide that to the Intent.  For this
latter, make sure you have set android:exported=true for the service.

Sorry I can't really help you with the first question, since I don't know
ADT that well.  Basically you will need to have both applications like the
generated aidl code into their app.

 Hi android developers,

 I'm new to the great android platform, trying to get into RPC with
 aidl and services.

 I didn't find a sufficient answer to my problem in any posts, if there
 already is one, please excuse and point me to it, thanks.

 I made 2 projects.

 project 1 hast an activity that binds to a service from project 2 on a
 button click (all just for testing).

 1. issue:

 How can I make project 1 know (import) my TestInterface (from
 TestInterface.aidl out of project 2) for usage in:

 TestInterface mService = (TestInterface)
 TestInterface.Stub.asInterface(service);

 without adding project 2 to the build path, because if I'd have an
 installed service without the project code, I couldn't do it this way,
 too...??
 I read in one thread that TestInterface.aidl should just be added to
 project 1, too, but if I do this, in DDMS enforceInterface() complains
 and seems to just see/use the interface from project 1 and it doesn't
 work.

 2. issue:

 (here i add project 2 to project 1's build path, which i still think
 is not how it should work)

 If i bind to a system service, i can simply do something like

 bindService(new Intent(com.android.A_SERVICE);

 but if i have my own service in project 2, something like

 bindService(new Intent(com.project2.A_SERVICE);

 does not work (of course, service 2 is installed on the emulator at
 that point, i provide an intent-filter an set the android:exported-
 attribute to true). the error i get is:

 05-16 15:06:06.384: ERROR/dalvikvm(820): Could not find method
 de.roberlin.new_rpc.TestInterface$Stub.asInterface, referenced from
 method de.roberlin.new_rpc.New_RPC_Client$2.onServiceConnected
 

 this error makes really no sense to me, any suggestions?

 btw: i ran adb shell dumpsys package and my Service is registered:

 Service Resolver Table:
 ...
 Non-Data Actions:
  ...
  de.roberlin.new_rpc.action.NEW_RPC:
436578f0 de.roberlin.new_rpc/.TestStringService

 The code from both projects can be reviewed at
 http://pastebin.com/f4bd0bc10

 I hope my points (special concern lies on the error message..) are not
 to nooby.

 I'd really appreciate any help! Thanks in advance!

[android-developers] How to set some lists in one layout?

[daehoon]

How to set a few lists in one layout include their own data from DB?

here is source code about set list in Android guide. List id is
@android:list
why the id must be android:list?, may I use my own id?
If I can, how to set lists to main layout including their own data
(title)?

   Cursor notesCursor = mDbHelper.fetchAllNotes();
   startManagingCursor(notesCursor);
   String[] from = new String[]{NotesDbAdapter.KEY_TITLE};
   int[] to = new int[]{R.id.text1};
   SimpleCursorAdapter notes =
   new SimpleCursorAdapter(this, R.layout.notes_row_weekly,
notesCursor, from, to);
   setListAdapter(notes);

I want to set lists like this :

 
 |   List1  List2|
 |   title1   |   title |
 |   title2   |   title |
 |   title3   |   title |
 | |   title |

[android-developers] Re: Drawing on the incoming call screen

[iPaul Pro]

Perhaps you could try launching an activity with a transparent
background, strategically positioned, that fires when an incoming call
is received. It will have the same UI effect. I assume that this is
the way other apps achieve this feature.

[android-developers] Re: How to set some lists in one layout?

[Mark Murphy]

 How to set a few lists in one layout include their own data from DB?

Use multiple ListView widgets in the layout. Either have one handled by
ListActivity and you handle the other(s), or handle all of them yourself.
It's not that hard.

 here is source code about set list in Android guide. List id is
 @android:list
 why the id must be android:list?,

So ListActivity, if you are using it, knows which list it is handling.

 may I use my own id?

You can, for any ListView widgets you are handling yourself:

[android-developers] trouble with Contacts groups

[Thomas]

Hi group.

I want to be able to have persons that are synced wih Google, still
are not visible by default. My idea is to have then in a special group
but not in the system group Contacts. This is what I do:

I create a Contacts group as follows:

Uri uri = Contacts.Groups.CONTENT_URI;
ContentValues values = new ContentValues();
values.put(Contacts.GroupsColumns.NAME, name);
values.put(Contacts.GroupsColumns.SHOULD_SYNC, 1);
uri = cr.insert(uri, values);

This is how I create a person and add it to this group:

ContentValues personInfo = new ContentValues();
personInfo.put(Contacts.PeopleColumns.NAME, name);
ContentResolver cr = context.getContentResolver();
Uri newEntry = cr.insert(People.CONTENT_URI, personInfo);
Cursor c = cr.query(newEntry, new String[] { BaseColumns._ID }, null,
null, null);
if ((c != null)  (c.moveToFirst())) {
long personId = c.getLong(0);
Contacts.People.addToGroup(cr, personId, groupId);
}

On the emulator this works just fine. But on a real G1 it appears that
after some seconds (possibly after it has been synced with Google) the
contact also belongs to the system group Contacts,

Any idea how to prevent this? To put it more generally, what I need is
to be able to create persons that are part of the contacts list, still
they are not shown by default.

Thank you very much in advance.

Regards
Thomas

 android:layout_height=wrap_content /
ListView
  android:id=@android:id/list2

[android-developers] Re: How to set some lists in one layout?

[Mark Murphy]

 Can you show me a simple ex.?

Not readily. I do not know of an example with multiple ListViews, since
that is an uncommon UI pattern.

 If this is two lists in main xml.
 ListView
   android:id=@android:id/list1
  android:layout_width=fill_parent
  android:layout_height=wrap_content /
 ListView
   android:id=@android:id/list2
  android:layout_width=fill_parent
  android:layout_height=wrap_content /

No.

Step #1: Switch away from ListActivity and just use Activity. ListActivity
is simply confusing you.

Step #2: Replace your android:id values in the above XML with ones that
look like

android:id=@+id/list1
android:id=@+id/list2

 ListView ls1=(ListView)findViewById(R.id.list1);
 ListView ls2=(ListView)findViewById(R.id.list2);

If you follow the above steps, those statements will work.

 then how to set List?
 ???
 SimpleCursorAdapter notes =
   new SimpleCursorAdapter(this, R.layout.notes_row_weekly,
 notesCursor, from, to);
   setListAdapter(notes); ???

ls1.setAdapter(), as documented in:

[android-developers] A suggested way to deal with long running tasks across context switches.

[Parakoos]

I was excited to see the introduction of the AsyncTask. Anything to
make the division of UI / Background work easier is good in my book.

What bugged me was that I couldn’t see a way to keep a long running
process alive during a context switch e.g. a layout orientation
change. As far as I could see, the common way to ‘solve’ the problem
was by stopping the process and then recreate it in the new Activity.
This will work in some cases, but in others it won’t work. For
example, a background task of creating a new user account on a website
cannot be re-sent easily.

I spent a day and hacked out an alternative way of doing things. My
approach was this.

* We know that the AsyncTask contains a Context which is the
Activity that creates it. So it must be destroyed when the Activity is
destroyed e.g. at a context switch due to a screen orientation change.
* Since we want to background task to continue ‘across’ a context
switch we cannot define the background task within the AsyncTask.
Instead we create a Future and pass that to some implementation of
AsyncTask that only wait for the Future to compute.
* At a context switch we can destroy the AsyncTask without
interrupting the Future which we can hold on to.
* When creating the new Activity post-context switch we create a
new fresh ASyncTask and give it the same still running Future.

The easiest way to understand this is to see it in action. I've
uploaded an example implementation of the above idea to:
http://www.shodansoftware.com/DevelopmentTools/BackgroundProcesses

You're free to check it out and make use of it as you please. If you
do use it though, I'd appreciate if you'd let me know just so I can
get that warm fuzzy feeling of having helped someone out. If you have
comments or suggestions, again, I'd like to know.

Thanks!

[android-developers] Re: Errors on Windows 7

[Al Sutton]

I've just run my own tests with the Google 1.5_r1 SDK and Win 7 RC 32 bit and 
it worked without any problems and without the need to use compatibility mode.

I used a clean fresh install of Win 7 RC from the DVD and unzipped the SDK 
downloaded from Googles site.

Maybe something you've installed is causing problems (did you try and do an 
upgrade in place of a Win7 Beta?).

[android-developers] Re: Install Android on Windows XP

[Pierre Bonnefoy]

The link you used can no longuer work with the new version of the sdk
because the parameters to pass to the emulator when you launch it have
changed.

Basically, what was described could work (the other methods described
in the answers requires that you install eclipse, which is not
mandatory if you just want to do in browser testings).

exchanged already on those lists, so with a fine search, you should be
able to find it, or one cool guy on this list should be able to give
it to you.

 If you install via an ADT zip file, make sure you get the latest (0.9.1).

 Rather than using the zip file, use the update size in Eclipse to
 automatically get the latest version
 (https://dl-ssl.google.com/android/eclipse/). Remember that for most
 people this fails via https so just use the http link
 (http://dl-ssl.google.com/android/eclipse/).

[android-developers] Emulating GPS using DDMS on sdk 1.5 not working on an sdk 1.1 application run on a 1.1 sdk emulator

[RodgerWilko!]

Hi,

Has anyone else had this or know a solution?

I've just upgraded to sdk 1.5 and i'm trying to pump in fake gps co-
orindates using ddms and a gpx file on an application/emulator running
on the old sdk 1.1.  When I press the play button the emulator dose
not recieve the GPS updates which i've signed up for using a
locationlistener.

This use to work fine when I was developing using the sdk 1.1 using a
1.1 emulator in eclipse, i'm not sure why it has stopped working when
I upgraded to sdk 1.5 or how to get it working again, please help!!

Just to test, I ran the program with a target of 1.5 on a 1.5 sdk
emulator and the emulator picked up the new GPS co-ordinates perfectly
so it's really confusing!

Thanks in advance,

RodgerWilko!

In the android market the countries where your app should be published

How is the country determined ?

Where the device was bought ?
Which country SIM is inserted ?
Which GSM network it is currently connected to ?
Which country was specified in the google account ?

[android-developers] Re: Emulating GPS using DDMS on sdk 1.5 not working on an sdk 1.1 application run on a 1.1 sdk emulator

[RodgerWilko!]

Ok - this was a strange one.  My application used the SD-card to
access data and the emulators virtual SD-card had a lock on it
(indicated by a directory with a .lock extension) .. so the
application was not recieving the updates as it could not access the
data on the SD-card ..

I removed the directory and the location updates started to flow!

  I tried the following piece of code to take a picture on 1.5:

  It works but the resulting image is 512x384 (on the ADP1).

  The doc says If the EXTRA_OUTPUT is not present, then a small sized
  image is returned as a Bitmap object in the extra field. If the
  EXTRA_OUTPUT is present, then the full-sized image will be written to
  the Uri value of EXTRA_OUTPUT.

  But 512x384 looks 'rather small-sized' to me!

  So what the correct way to get the full-sized version?

  Thanks a lot for your help!

[android-developers] Re: aidl remote service call namespace question

[dev_rob]

I now have the TestInterface.aidl in both eclipse projects and project
2 (the service project) is added to project 1's build path.

I declared the service in the manifest-file with:

service android:name=.TestStringService
android:exported=true
android:process=:remote
intent-filter 
action android:name=de.roberlin.new_rpc.action.NEW_RPC/
/intent-filter
/service

and adb shell dumpsys package shows it successfully registered to
the emulator.

I try to bind to the service with:

String intentAction = de.roberlin.new_rpc.action.NEW_RPC;
Intent iService = new Intent(intentAction);
bindService(iService, myService, Context.BIND_AUTO_CREATE);

DDMS won't stop telling me:

05-17 14:14:34.285: WARN/ActivityManager(567): Unable to start
service Intent { action=de.roberlin.new_rpc.action.NEW_RPC }: not
found

In fact, after running project 1 (the activity binding to the service)
and getting the error message, when I do

adb shell dumpsys package

again, it does not list my service anymore. how can this be???

the steps were:

1.) installing the service onto a new emulator (adb shell dumpsys
package lists it then correctly)

2.) installing/running project 1 (leads to the error message above)

3.) now adb shell dumpsys package does not list the service anymore.
even if i reinstall it, it won't be listed anymore until I start a new
emulator and intall it freshly.

I really do not know, how to deal with this and would be really
thankful for any help!!

best regards!

 latter, make sure you have set android:exported=true for the service.

 Sorry I can't really help you with the first question, since I don't know

  I didn't find a sufficient answer to my problem in any posts, if there

  I made 2 projects.

  project 1 hast an activity that binds to a service from project 2 on a
  button click (all just for testing).

  1. issue:

  How can I make project 1 know (import) my TestInterface (from
  TestInterface.aidl out of project 2) for usage in:

  TestInterface mService = (TestInterface)
  TestInterface.Stub.asInterface(service);

  without adding project 2 to the build path, because if I'd have an
  installed service without the project code, I couldn't do it this way,
  too...??
  I read in one thread that TestInterface.aidl should just be added to
  project 1, too, but if I do this, in DDMS enforceInterface() complains
  and seems to just see/use the interface from project 1 and it doesn't
  work.

  2. issue:

  (here i add project 2 to project 1's build path, which i still think
  is not how it should work)

  If i bind to a system service, i can simply do something like

  bindService(new Intent(com.android.A_SERVICE);

  but if i have my own service in project 2, something like

  bindService(new Intent(com.project2.A_SERVICE);

  does not work (of course, service 2 is installed on the emulator at
  that point, i provide an intent-filter an set the android:exported-
  attribute to true). the error i get is:

  05-16 15:06:06.384: ERROR/dalvikvm(820): Could not find method
  de.roberlin.new_rpc.TestInterface$Stub.asInterface, referenced from

  btw: i ran adb shell dumpsys package and my Service is registered:

       de.roberlin.new_rpc.action.NEW_RPC:

[android-developers] Sprite imaging for 2D game programming

[g1port.com]

Hi guys,

For a 2D game programming, I'm trying to learn about loading
an image file for all states of a game character (simply a walking
soldier lets say) and simply animate it. I think this classic method
is called as sprite imaging that you load whole image of all states of
the character that you want to animate.

Is there anyone that can provide some sample code about this or at
least can you tell me which classes to use, how to refer some 'part
of' whole image file and animate it etc.

Your help is much appreciated.

Thanks a lot.

through onRetainNonConfigurationInstance() as long as the object doesn't
have any ties to the current activity -- so basically make sure it is static
(if an inner class), and be able to change its pointer back to the Activity
or whatever when you get it in the next activity's onCreate() after
onRetainNonConfigurationInstance().

 This will work in some cases, but in others it won’t work. For

 cannot be re-sent easily.

 I spent a day and hacked out an alternative way of doing things. My
 approach was this.

* We know that the AsyncTask contains a Context which is the
 Activity that creates it. So it must be destroyed when the Activity is
 destroyed e.g. at a context switch due to a screen orientation change.
* Since we want to background task to continue ‘across’ a context
 switch we cannot define the background task within the AsyncTask.
 Instead we create a Future and pass that to some implementation of
 AsyncTask that only wait for the Future to compute.
* At a context switch we can destroy the AsyncTask without
 interrupting the Future which we can hold on to.
* When creating the new Activity post-context switch we create a
 new fresh ASyncTask and give it the same still running Future.

 The easiest way to understand this is to see it in action. I've
 uploaded an example implementation of the above idea to:

 You're free to check it out and make use of it as you please. If you

[android-developers] Re: aidl remote service call namespace question

[dev_rob]

I think it's rather a problem with namespaces. And the package names
in both projects are indeed identical!

But as (one of my original questions) both projects have to contain
the TestInterface.aidl the package names must be the same, because
otherwise there is a different package name in TestInterface.aidl and
then it's not the same interface anymore and enforceInterface()
complains about that...

If you have a suggestion for this issue, it would be great (I guess
there is a simple solution for this)! I could see then, if that has
something to do with the fact, that the service seems not to be
registered after executing the calling activity (project 1).

Thanks again!

I read in one thread that TestInterface.aidl should just be added to

[android-developers] Fastest way to load images

[The Savage Killer]

Hey, I'm currently developing a game, and I need to know the best way
to reference its sprites for drawing. Right now I have a pretty simple
runnable thread that starts after the application starts, so it
doesn't hang, and loads up every drawable to a variable. Like so;

new Thread(new Runnable() {
public void run() {
Resources res = mContext.getResources();
BackgroundImage = res.getDrawable
(R.drawable.clouds2);
   mBackgroundRays = res.getDrawable
(R.drawable.lightrays);
   mBackgroundLoaded = true;
   mMenuBunz = res.getDrawable(R.drawable.menu);
mMenuLoaded = true;
mGameLayout = res.getDrawable
(R.drawable.game);
mFoods[0] = res.getDrawable(R.drawable.bunbot);
mFoods[1] = res.getDrawable(R.drawable.patty);
mFoods[2] = res.getDrawable(R.drawable.pattybad);
mFoods[3] = res.getDrawable(R.drawable.gold);
mFoods[4] = res.getDrawable(R.drawable.bacon);
mFoods[5] = res.getDrawable(R.drawable.baconbad);
mFoods[6] = res.getDrawable(R.drawable.cheese);
mFoods[7] = res.getDrawable(R.drawable.cheesebad);
mFoods[8] = res.getDrawable(R.drawable.onions);
mFoods[9] = res.getDrawable(R.drawable.onionsbad);
mFoods[10] = res.getDrawable(R.drawable.tomatoes);
mFoods[11] = res.getDrawable(R.drawable.tomatoesbad);
mFoods[12] = res.getDrawable(R.drawable.lettuce);
mFoods[13] = res.getDrawable(R.drawable.lettucebad);
mFoods[14] = res.getDrawable(R.drawable.buntop);
mFoods[15] = res.getDrawable(R.drawable.life);
mFallingFood[0] = new Food();
mFallingFood[1] = new Food();
mFallingFood[2] = new Food();
mFallingFood[3] = new Food();
mFallingFood[4] = new Food();
mFallingFoods = FOOD_MAX_FALLING;
mGameLoaded = true;
mMenuScores = res.getDrawable(R.drawable.highscore);
mScoresLoaded = true;
mMenuHelp = res.getDrawable(R.drawable.help);
mHelpLoaded = true;

mResLoaded = true;
}
  }).start();

That's about 700kb worth of images loaded, but its loading times on
the phone are random. Sometime the images take 5 seconds to load and
at other times they can take up to 20 seconds. Can someone please tell
me how to properly load up my sprites? Thanks.

 May emulator support all .mp4 files...?

Not really, for two reasons. First of all, mp4 is a container
format, not an encoding, and this container can contain various
encoded streams, including unsupported ones. Second, even if the
format is a supported one like H.264, the emulator would have to
decode it in software (whereas the phone has hardware support), and
might not be fast enough to keep up.

If you run the sample in 1.5 SDK in the emulator, you'll be able to
use it by enabling it in Settings-Localetext.
Then go to any text-box, and do long press on it, till a context menu
will open up.
Select from this menu Input method, and select the new soft
keyboard.

[android-developers] Re: A suggested way to deal with long running tasks across context switches.

[Romain Guy]

Like Dianne said, an AsyncTask doesn't take a Context. If you are
careful about what references you keep in the AsyncTask, there will be
no problem at all.

The implementation you link to has two issues in my opinion: it is not
as easy and straightforward as AsyncTask, and you lose the ability to
post progress on the UI thread from doInBackground().

[android-developers] What is Context for?

[Makeable]

I have just started on a new application that will use SQLite for
persistance and Im a bit confused over the usage of a context when
utilizing the SQLiteOpenHelper.

I have a base class called Storable, which my models extend if they
need to be persisted.
i had intended to use a synchronized singleton database adapter, but I
can't for the life of me understand how to utilize the
SQLiteOpenHelper as it requires a context, which my models don't
appear to possess.

Im aware that I can get around this by not using the SQLOpenHelper -
but if this restriction is in place, I would assume its to prevent
people creating apps the wrong way for android.

What is the best practice way for saving models in the database?

I'm now on my 26th hour of no sleep, so any advice would be very much
appreciated :)

Handler object to interact with this thread from the worker thread.

[android-developers] Null reference to ImageView from custom view

Hi,
I have the following xml layout:

android.pacman.com.PacManMainView

  android:layout_height=fill_parent


   ImageView android:id=@+id/pacAnim

android:layout_height=20px/
/android.pacman.com.PacManMainView

PacManMainView extends SurfaceView. I can draw to this, it works OK.
However, when I attempt to get a reference to the ImageView like this:

@Override
public void surfaceCreated(SurfaceHolder holder) {
/* test reference to imageview
ImageView pacImageV = (ImageView) findViewById(R.id.pacAnim);

[android-developers] Module version conflicts between wlan module and Android kernel source

[Jim Bray]

Hi,

  I'm tinkering with building and installing Android from source.
Basically I've got it down fairly well, but I seem to have run into a
bit of a problem with the wlan module, probably from HTC.

  Having pulled the 2.6.27 kernel sources and built that with
a .config pulled from the phone, and using that as the kernel image
instead of the prebuilt one, I get the following wifi failure message
in dmesg:

wlan: version magic '2.6.27-00205-gf2dabc0 preempt mod_unload ARMv6 '
should be '2.6.27-00392-g8312baf preempt mod_unload ARMv6 '

probably because the .config I pulled from the phone has:

CONFIG_LOCALVERSION=-00392-g8312baf

So I rebuilt with the '00205' localversion and now I get in dmesg:

[   61.122497] wlan: Unknown symbol trout_pwrsink_set

but trout_pwrsink_set was changed to htc_pwrsave_set way back in
February:

[ARM]: trout: Switch from trout_pwrsink - htc_pwrsink  33/8933/1
http://android.git.kernel.org/?p=kernel/msm.git;a=commitdiff;h=44a01f54989b1c8669a8075189886a1bdf29bc17

  I'm clearly getting an obsolete wlan module somehow, Any ideas for
how I can get a wlan module that goes with the '00392' kernel would be
appreciated.

[android-developers] How to make games faster? Using view and redraw is way to slow it seems.

[klirr]

I have done a simple game where I draw on a View and use invalidate()
to force onDraw to be called.
This however doesn't seem to scale at all since even for this little
game it is quite slow.

So what is the solution, to use openGL? that is what all games should?
and then I should use frames rather than redrawing?

[Marco Nelissen]

If this is indeed the case, then the ImageView isn't actually there,
so you can't get a reference to it.

[android-developers] Re: Null reference for ImageView

[steve_macleod]

So if I had:

FrameLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=fill_parent
android:layout_height=fill_parent

android.pacman.com.PacManMainView
  android:id=@+id/pacman_main_view
  android:layout_width=fill_parent
  android:layout_height=fill_parent
/android.pacman.com.PacManMainView

ImageView android:id=@+id/pacAnim
 android:src=@drawable/pac02
 android:layout_width=20px
 android:layout_height=20px/
/FrameLayout

How would I go about getting a reference to the ImageView from
PamManMainView?

Thanks again

[android-developers] Re: Null reference for ImageView

[Marco Nelissen]

From PacManMainView, you would first get the parent view (the
FrameLayout), and from there you can find the ImageView.

[android-developers] Throttling rate of messages to handler

[al capwn]

My app makes use of threads and uses handlers to send messages to the gui.
The thread maintain a connection to a server and receive messages from it.

The problem I'm having is that sometimes messages arrive really fast, and
although the app doesn't anr, the UI freezes as it tries to cope with the
fast influx of messages in the queue.

The rate at which messages arrive from the server is beyond my control, but
I need to find a way to throttle to make sure the UI stays responsive. I've
read about people having issues in games where touch events have a negative
effect on fps and they've used thread.sleep to throttle. Although similar to
my issue, I don't think it would work for me because both the UI and
background threads as just as important here.

Does anyone have any other ideas for solving this? Thanks.

[android-developers] Re: aidl remote service call namespace question

[Dianne Hackborn]

If you have give the .apks the same name, you can't have them both installed
at the same time, because they are both effectively the same app.

You can have classes in whatever namespace you want inside of the .apk (and
even publish these in the manifest via fully qualified class names).

On Sun, May 17, 2009 at 8:37 AM, dev_rob robwiene...@googlemail.com wrote:


 I think it's rather a problem with namespaces. And the package names
 in both projects are indeed identical!

 But as (one of my original questions) both projects have to contain
 the TestInterface.aidl the package names must be the same, because
 otherwise there is a different package name in TestInterface.aidl and
 then it's not the same interface anymore and enforceInterface()
 complains about that...

 If you have a suggestion for this issue, it would be great (I guess
 there is a simple solution for this)! I could see then, if that has
 something to do with the fact, that the service seems not to be
 registered after executing the calling activity (project 1).

[android-developers] Re: Throttling rate of messages to handler

[Dianne Hackborn]

Correct it wouldn't work, since there is a lot of careful dispatching code
in the window manager that this sleep trick is actually relying on.

There are many ways you can perform throttling, depending on your exact
situation.  For example:

1. Put a delay before you send a message, so if you get more information
from the server during that time it can be batched together.
2. Watch for situations where you are generating many messages within a
certain amount of time, and start batching/delaying when in that situation.
3. Have some mechanism to find out when the app is done processing a
message, and don't send the next message until that occurs (batching
activity from the server during that time).  (Fwiw, this is basically what
the window manager does for dispatching events to applications.)
