[android-developers] Lot of unused code is generated when aidl tool is run againt a .aidl file.

[krr_android]

Hi

This is my aidl file.
IRemoteCounterServiceCallback.aidl

package com.training;

import com.training.IRemoteCounterServiceCallback;
import com.training.myCounter;

interface IRemoteCounterService {
  // Remote service interfaces
  int StartCounters(in myCounter counter);

  void registerCallback(IRemoteCounterServiceCallback cb);
  void unregisterCallback(IRemoteCounterServiceCallback cb);
}
---

The aidl generates

public static abstract class Stub extends android.os.Binder implements
com.training.IRemoteCounterService
{

}

containing an inner class

public static abstract class Stub extends android.os.Binder implements
com.training.IRemoteCounterService
{

}

here the abstract class Stub contains:
1. Impl for public boolean onTransact(int code, android.os.Parcel
data, android.os.Parcel reply, int flags) throws
android.os.RemoteException
(this is never invoked)

2. an inner class, private static class Proxy implements
com.training.IRemoteCounterService, which implemeted the following the
methods which are never invoked whent the program is run:
  a. public int StartCounters(com.training.myCounter
counter) throws android.os.RemoteException

  b. public void registerCallback
(com.training.IRemoteCounterServiceCallback cb) throws
android.os.RemoteException
  c. public void unregisterCallback
(com.training.IRemoteCounterServiceCallback cb) throws
android.os.RemoteException


My Application runs fine even if I remove the above mentioned unused
code from Stub class.

Now the Stub has just 3 methods,

public abstract class Stub extends android.os.Binder implements
IRemoteCounterService
{
public Stub()
{
this.attachInterface(this, DESCRIPTOR);
}
public static IRemoteCounterService asInterface(android.os.IBinder
obj)
{
if ((obj==null)) {
return null;
}
android.os.IInterface iin = (android.os.IInterface)
obj.queryLocalInterface(DESCRIPTOR);
if (((iin!=null)&&(iin instanceof
com.training.IRemoteCounterService))) {
return ((com.training.IRemoteCounterService)iin);
}
return null;
}
public android.os.IBinder asBinder()
{
return this;
}
}

Why does the aidl generate code for

1. onTransact() inside Stub class??
2. inner class Proxy ??

Pls clarify. Thansk in advance.

[android-developers] Direct access to GEARS geolocation without going through the browser interface

[alexdonnini]

Hello,



I have searched this group's archives, and several other sources for

information on direct access to GEARS geolocation functions from an

Android application. To date, I have not found any.



geolocation includes three Android-specific public Java classes,

AndroidGpsLocationProvider, AndroidRadioLocationProvider, and

AndroidWifiLocationProvider. The fact that they are Android-specific

and that they are public lead me to conclude that I should be able to

use these classes in my application.



However, not surprisingly, when I try to access these classes, my

application fails (see log below) because, among other things, I have

no way to correctly identify nativeObject in the java classes.



I would appreciate anyone's feedback, suggestions, and help in

resolving this problem. At the very least, I would like to understand

the purpose of the three Android-specific public Java classes, and how

we should use them.



Thanks.



Alex  Donnini

[android-developers] Dose Android sdk 1.5 allow to create our own screen when a call is in or out

[Jason Proctor]

if you bring up an Activity with UI when the phone state listener 
goes off, the call UI appears on top of it. you can hit the back 
button to get back to your Activity, but, again, there is no current 
way to override the call UI.

you have to live with it for now.

[android-developers] Dose Android sdk 1.5 allow to create our own screen when a call is in or out

[Jason Proctor]

ISTR a response from Dianne not so long ago which said that the 
in-call experience is not currently changeable via the Java API.

so in other words you'd have to modify the native parts of Android 
(the firmware) and then ship your own Android distribution. probably 
more work than you want to take on.

i hope the in-call experience will be pluggable soon, too.

[android-developers] Possible solution: showDialog and dismissDialog behave strangely when changing orientation

[Streets Of Boston]

I found the problem... and a solution

In my activity, i show the dialog using:

  this.showDialog(R.layout.waiting_dialog);
(where 'this' is the current activity).


Then this code, part of my activity, dismisses it:

  // Do something with bmToSave and insert it into the MediaStore.
  final PictureInserter ph = new PictureInserter(getApplicationContext
(), bmToSave) {
  @Override
  public void ready(String path, Uri uri) {
  this.dismissDialog(R.layout.alert_dialog_waiting);
  }

After an orientation change, the problem is that 'this' is still the
old destroyed acivity, when the 'ready' is called back when the
picture is properly inserted into the MediaStore.

I changed the code as follows:

  // Do something with bmToSave and insert it into the MediaStore.
  final PictureInserter ph = new PictureInserter(getApplicationContext
(), bmToSave) {
  @Override
  public void ready(String path, Uri uri) {
  ACTIVE_INSTANCE.dismissDialog(R.layout.alert_dialog_waiting);
  }

where 'ACTIVE_INSTANCE' is set to 'this' in the onCreate (and set to
'null' in the onDestroy).
This works fine.

[android-developers] Re: how to find out the percentage of memory used by each process in the android

[Roman]

You could run the top command in the adb shell. The command comes with
busybox.

The memory information include:
Statistics on memory usage, including total available memory, free
memory, used memory, shared memory, and memory used for buffers. The
display of memory information may be toggled by the m interactive
command.

[android-developers] Re: Camera preview on an OpenGL surface....

[Richard Schilling]

I solved this, thanks in part to
http://groups.google.com/group/android-beginners/browse_thread/thread/489e56ea2a1d42a9/994eb23731f60650?lnk=gst&q=OpenGL+View+on+top+of+Camera#994eb23731f60650

Follow the instructions on that thread.  Here's the general strategy:

1. In your main activity, set as the main view the GLSurfaceView
object using the setContentView method.
2. Then, add the SurfaceView being used to draw the camera.
3. Add other SurfaceViews to the display as necessary.

That order is very important, otherwise the views block each other.

No, the only responses you will get is from people other than Google
employees. As Romain Guy pointed out, if you read the response you were
lambasting, you would notice that it is from a T-Mobile employee.

It seems curious that you seem to have made the same error that you are
complaining about -- not completely reading the email. It's almost as if
making mistakes were, like, human or something.

Of course, it is also curious that you appear to think this is an
end-user tech support forum (which it is not) and that it is Google's
primary responsibility to respond to you here (which it is not).

But I digress.

> No status updates or responses on the bug report from 7+ months ago.

Please point out the official public bug trackers for Windows Mobile,
Blackberry, iPhone, and Palm WebOS. I'm not even sure there's one up for
Symbian, and they're at least on the road to open source.

Please point out where you get detailed, bug-level information months in
advance of product releases for Windows Mobile, Blackberry, iPhone, Palm
WebOS, and Symbian.

Please point out how you -- whether via your own engineering efforts, or
by hiring somebody, or by collecting interested people to raise money to
hire somebody -- have a chance to fix bugs in Windows Mobile,
Blackberry, iPhone, or Palm WebOS, as you can with Android. I'll give
Symbian a mulligan here, since they're in progress on this issue.

Had this same bug, or an equivalent one, affected you on one of these
other platforms, the best-case scenario is that, after sitting in
indefinite tech support queues, you would be told it is a bug and it may
get fixed someday. Here, not only were you able to file the bug report
without much effort (albeit with no better of a response), but you have
options for spearheading a fix, which you lack with any other
commercial-grade smartphone platform.

Now, you may not elect to use any of those options to accelerate a fix,
but that's your decision, not Google's. Regardless, you are no worse off
than you would have been with any other platform with the same sort of bug.

If you want to whine about how Android has bugs, be my guest, just don't
whine about the lack of response, since that's all you'll get from anyone.

Note: once Symbian gets a-rollin' in earnest on the open source front,
the bar for Google and Android may get raised a fair bit, but we're not
there yet.

[android-developers] Re: ListView (ExpandableListView as well) selector highlight problems with custom background

[Dimitris]

Thank you and I am sorry if I sounded impatient.

I tried what you said and it worked out! However, I am still having
problems with the Linkify. If there is a link in my text it seems that
it grabs the onClick listener for the whole list item.

Any ideas on how to fix this?

Thanks again,

Dimitris

[android-developers] Re: Tut (SDK 1.5) Get google account of user

[kostmo]

Hi ubikdroid,
Would you be able to tell me more about how you used getCredentials?

I'm trying this variation: getCredentials
(android.app.Activity,int,android.os.Bundle, java.lang.String,
java.lang.String, boolean)

Called from my activity, it is
getCredentials(this, 345, null, email, null, false);

Where 'email' is obtained from getAccount beforehand.  I have added
com.google.android.googleapps.permission.GOOGLE_AUTH.OTHER_SERVICES to
the manifest.  As opposed to the getAccount method, which returned an
array containing the email address, the getCredentials method called
with the above arguments returns null.  With what arguments are you
calling getCredentials?

The only docs I can find relating to this (http://
www.androidjavadoc.com/m5-rc15/com/google/android/googleapps/GoogleLoginServiceHelper.html)
seem to be outdated (wrong number of arguments).

Thanks,
Karl

[android-developers] Re: Android BUG....

[dotclick]

So the only response I am going to get from Google is from someone who
didn't read the message or take the time to research it.

No status updates or responses on the bug report from 7+ months ago.
If this is all Google has to offer, I don't think we will be using any
Google services in the future.

[android-developers] Camera preview on an OpenGL surface....

[Richard Schilling]

Just getting started with OpenGL surfaces, really.

I'd like to display a camera preview in the background on its own
surface (no problem there).
And, I'd like to draw on another surface layered on top of that with a
OpenGLSurfaceView.

But the OpenGLSurfaceView completely blocks the view camera preview.

What's the best way to either
a) use the OpenGLSurfaceView for the camera preview and then draw on
top of the camera preview, or
b) create an OpenGLSurfaceView object with a transparent background
(which, I don't think is possible?).

Thanks.

[android-developers] How to get a child views of particular TableRow in TableLayout ?

[Mapara,Harshit Nitinkumar]

Hi All,

Here is my screen description:
It is a TableLayout and it contains multiple Rows.
I have set TableRow as clickable, as I want to go to next screen on
click of a tableRow.
Everything I am doing through Java programming (instead of XML layout,
because number of TableRows  changes each time)

On next screen, I wanted to display all the views of that particular
clicked TableRow.
Here the problem i am facing is how to capture particular tableRow  on
onclick() even and how do I get all the textviews of that particular
Row.

I tried to set id at runtime, and tried to get id of view, but it's
not working, giving error resourcenotfoundexception.

Thanks
Harshit

[android-developers] Re: MediaPlayer.create always returning null (SQLite URI Problem Maybe?)

[Rick]

I am able to play it just as I would any other .mp3 file in iTunes,
WMP, Quicktime, etc, and .mp3 is definitely a supported file type
because I can stream it straight from the http. A permissions problem
is a case that I have not yet investigated. I will look further into
that angle and see if the problem lies there.

Thanks for all your help Marco.

Play it using what?

That would seem to indicate that the file is not in a supported format.
You can doublecheck this by copying it your sd card and using the
music app to play it.
If the music app does play it, then I suspect a permissions problem
(i.e. the media service can't access the file)

[android-developers] Re: Fast, efficient usage of an object pool

[Romain Guy]

We have an efficient implementation for you: use the Pools.java file
from 
http://android.git.kernel.org/?p=platform/frameworks/base.git;a=tree;f=core/java/android/util;h=728ff2a95d2b382c4a16a28cc9766d29bc84e1b3;hb=master
(and the associated classes.) These are not public APIs so just copy
the code in your application.

Here's an example of a Poolable object with this API:
static class InvalidateInfo implements Poolable {
private static final int POOL_LIMIT = 10;
private static final Pool sPool =
Pools.synchronizedPool(
Pools.finitePool(new PoolableManager() {
public InvalidateInfo newInstance() {
return new InvalidateInfo();
}

public void onAcquired(InvalidateInfo element) {
}

public void onReleased(InvalidateInfo element) {
}
}, POOL_LIMIT)
);

private InvalidateInfo mNext;

public void setNextPoolable(InvalidateInfo element) {
mNext = element;
}

public InvalidateInfo getNextPoolable() {
return mNext;
}

static InvalidateInfo acquire() {
return sPool.acquire();
}

void release() {
sPool.release(this);
}
}

[android-developers] Fast, efficient usage of an object pool

[Brad Larson]

At Google I/O and in the forums, it has been clear that if you need
optimal performance, you must avoid memory allocation inside tight
loops.  I'm curious about the best way to handle this in my use-case,
which I think must be fairly common.  I need to access at most n
objects of type MyObject, I need to iterate over them during every
screen refresh,  and I need to remove them and put them back in the
object pool randomly.

The object pool seems pretty straight-forward, just use a
Vector(n), add n copies of MyObject at bootup, and add/
remove from the end to avoid any memcpy or allocation.

The iterating is a little more difficult.  I can use for(MyObject m :
myObjects), but this will allocate memory to create the iterator.  I
could create a static final Iterator at bootup, but there is no good
way to get back to the start of the List.  For now, I'm using another
Vector for active MyObjects, and a for loop with an int to get() the
objects and avoid allocating an iterator.  get() runs in constant time
for a Vector, so this works well.

However, when an object is done, I need to remove it and send it back
to the pool.  If I use Vector.remove(i), it has to memcpy everything
after i.  I could use an Iterator on a LinkedList, which can remove()
in constant time, but I don't think there is a good way to get the
Iterator back to the start of the list without allocating memory.  I
could use an int to loop through a LinkedList, but LinkedList.get(n)
runs in O(n) time.

Any tips on the optimal way to solve this?  Worst-case, I assume the
memcpy called during Vector.remove() is a better bet over allocating
an Iterator inside my app loop, correct?

Thanks!
Brad

[android-developers] Re: MediaPlayer.create always returning null (SQLite URI Problem Maybe?)

[Rick]

/data/data/etc. is the relative path to the file in the database. At
least I'm fairly certain that it is. So the idea is that it would play
it from its location in the database. This file at that path is fine
because using the DDMS Perspective within Eclipse I can navigate to
that path, pull the file locally, and play it no problem.

The full log print out is as follows.

I'm still confused, since you again said that the files are in a
SQLite database, but the code you posted wants to play
/data/data/project.android/files/musicfile.mp3 which is clearly just a
regular file path. So where does the database fit in to all this? Are
you pulling the data from a sqlite blob, writing it to a file, then
playing that file?
If so, you might want to verify that the file itself is actually OK
when you try to play it.
Also, is there anything else in the log? When MediaPlayer.create()
fails, something should be printed to the log that tells you why.

Hi,
when i go in my webview to a page with picture upload
i get "upload disabled" on that button.

How can i code my Webview, that my Android users

Thanks for the detailed info. This is good news.
((ok, now the only problem I see in my use case is if those broadcast
receivers launch services to continue their work, and then a couple of
services have to struggle for memory concurrently - but there is
probably not much the platform can do about that. Probably it is best
if each service indicates when it is done, so that the next apk can be
launched by the main program through an apk specific broadcast))

[android-developers] Re: MediaPlayer.create always returning null (SQLite URI Problem Maybe?)

[Rick]

The files are stored in a JSON Database in http format, but to
eliminate loading times since the application they will be used in
will also include video and time is a factor, prior to launching a
"game" I download the necessary files from the JSON Database to a
SQLite database on the phone.

I am able to stream the file directly from its full http path using
AsyncPlayer but there is a loading time I would like to avoid, and
AsyncPlayer does not work with video. I have not tested whether or not
the file would play from the sd card, but I am fairly certain that is
not the issue since I am able to pull the file from the SQLite
database and play it locally on my computer with no problems.

Sorry if that was slightly confusing. I'm not the best at explaining
things.

I'll need to upload the app to get the proper application search

upload to the app store in any context other than as a submission for
ADC invalidate my entry?

[android-developers] Extend core apps in the SDK

[dmodroid]

I know this topic has been covered a lot, so apologies if this is
redundant.  I would like to work in the SDK and simply extend a core
app that already exists, and then override some functionality.  For
example, I would like to extend Contacts, but then overwrite the
entire ContactsListActivity class, for my own experimental
MyContacts.apk.

In this youtube video: http://www.youtube.com/watch?v=3aUjukCdPyQ

Dianne talks about the ringtone picker, did she just extend the core
ringtone picker and work in the SDK?

I DO have the entire platform source code, and have made some changes
to core apps there, but rebuilding takes awhile (even useing mmm, and
snod), so I was hoping to speed up development by working in the SDK
(where building and running the emulator seems to go faster).  Not
sure if this is realistic or not.

This is all just for some internal experimentation, I am not looking
to contribute the the core apps.

In another post, someone had referred to " classes available in
the SDK".  How can we see what classes we have access to, in the
SDK.

thanks!

[android-developers] MediaPlayer.create always returning null (SQLite URI Problem Maybe?)

[Rick]

What I am trying to accomplish here is to get an audio file that I
have stored in an SQLite database on the phone, and play it upon
clicking a button. audioPath is the path to the file. The problem is
that MediaPlayer.create() is always null, even though I believe I am
giving it a correct Uri. Can anyone shed some light on this? Code
snippet below:

Uri uri = Uri.parse(audioPath);
Log.i(TAG,"AUDIO: " + uri.toString());
MediaPlayer mp = MediaPlayer.create(this, uri);
if (mp != null){
mp.start();
...

"AUDIO: /data/data/project.android/files/musicfile.mp3"

No. That statement create a Java object, in memory, and does not affect

[android-developers] Unable to write text file to sdcard on physical G1 device

[Jason Proctor]

making a File object does not create the actual 
file. usually it's created with a 
FileOutputStream or File.createNewFile() or 
somesuch.

as always, reading the docs pays dividends :-) 
also i'd recommend writing some little Java 
command line programs to get the feel of things. 
that way you don't have to deploy to the 
(relatively) hostile environment of the phone 
just to figure out stuff like File.

install a WebViewClient in your WebView and override 
shouldOverrideUrlLoading(). you can then decide what to do about a 
particular link and return whether the WebView should do anything 
about it or not.

this works most of the time for me. the only problem is that the link 
handler is *not* called when you reload the same URL - and the same 
URL in this instance means the same host and path, regardless of 
parameters. it's logged as an issue.

[android-developers] Re: Notification Manager Help

[Yusuf T. Mobile]

Your problem may be in the generic constructor "new Intent()". I
recommend you do something like:

Intent i = new Intent (this, Cvance383Activity.class)
.setAction(Intent.ACTION_MAIN)
.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, i,
0);

That is a matter of what MIME type the file is served as. Android tries
to find something on the device that can handle that MIME type.

[android-developers] Re: how to find out the percentage of memory used by each process in the android

[Dianne Hackborn]

Well take for example the alarm clock running, which I haven't launched
myself but whose process got launched from a broadcast at some point, so
shouldn't have done a whole lot:

  217   10496K   10496K2177K1400K  com.android.alarmclock

That's almost 1.5MB purely owned by the process and immediately made
available if the process is killed; the extra .6MB (bring us up to 2MB pss)
is shared memory, so it won't be available if the process is killed.

Considering the amount of memory on the device, a process is a
super-expensive object.  You really want to avoid using extra processes
where you don't need to, and this is why I am so adamant about people not
leaving a process sitting there running in the background forever.  (In fact
there just isn't the memory to allow for that, so by the time we got to 1.0
the system became quite aggressive about killing long-running processes,
even if they contain actively running services, to be able to keep the
overall experience decent.)

Oh and for the shared memory, you need to be careful in interpreting the
numbers -- it's not really .6MB that is shared, this has been weighted by
the number of processes sharing it.  So given this device currently has 13
Java processes running in it, you can figure that there is around 8MB that
we manage to share from zygote into the Java processes.  Thank ghod for
zygote. :)

If the broadcast needs to launch any .apks, it gets serialized so that only
one .apk is launched at a time.  Trying to just blindly launch a bunch of
apps to receive the broadcast would be very painful. :)

[android-developers] Content rendering for WebView

[m8]

Hi

Can anyone help me to understand how WebView decided which content it
can render and which it can't? For example I am inside a webview
select a link and if the link sends an XML file I want my application
to handle to data instead of WebView,

Is this possible?

Thanks,

-Amit

[android-developers] Re: Toast

[Dianne Hackborn]

Hi, this isn't really supported by toasts, which are designed to be shown
completely independently of the current app.  You can fairly easily
accomplish this by just displaying a normal dialog, except making it not
have focus or receive touch events and giving it an animation style that
fades in and then out.

[android-developers] Best Practice for overriding both Theme and Theme.Dialog correctly in an app?

[Robert Green]

I use themes in my apps, which generally just extend android:Theme and
then set a bunch of styles.

I use dialogs made from layouts, but since I set the theme for the
application, they have inherited all of the regular styles and no
longer carry a border, etc.

My question is:  How do I say, "I want everything to use this theme
which extends Theme, except dialogs, which should use this other theme
that extends Theme.Dialog"  ?  It seems like that's how things work by
default but when you set the theme to your own, you lose the dialog
theme!

Thanks for any help!

[android-developers] Re: how to find out the percentage of memory used by each process in the android

[Peli]

I have the following follow-up question:
Even for small apks (single broadcast receiver, few lines of code),
top shows a few MB of memory usage. Is there a rule of thumb how much
of this is shared and how much is approximately due to the apk?

(I'm especially interested in the situation where there is one main
program that sends a broadcast to several apks. Would this scale well,
or would this quickly fill up the memory, even if the individual apks
are small (since all broadcast receivers would be called
concurrently)).

That should work, assuming the height of widgets 1 and 3 are
wrap_content. If you have them be fill_parent, you will get the behavior
you are seeing.

[android-developers] WebView and HTTP Post requests

[Jason Proctor]

just reverse what i did :-)

after your request completes, get the Apache CookieStore object from 
your post object (post.getCookieStore()) and copy the relevant 
cookies to the WebKit CookieManager (CookieManager.getInstance()). in 
theory, this should result in those cookies being sent in future 
WebKit HTTP requests.

i have more confidence that this will work than the other way round.

[android-developers] Re: Problem of vertical alignment in a RelativeLayout

[elDoudou]

Thank you Mark for taking the time. Yes, my ASCII "art" does not fit
well with the browser non-fixed-space font.

 - Just to let you know that setting
android:layout_centerVertical="true" on the 3 widget does not solve
the problem (I forgot to mention that I had already tried...)
 - I cannot use a horizontal LinearLayout, because I forgot to mention
that the widget labelled 3 (the one of the middle), may be larger than
the screen width, and I want to make sure that the widget labelled 2
(the one on the right) is still visible and than widget 2 is limited
in width by the 2 other widgets. Or maybe, I missed something with
LinearLayouts...
 - Here is an image paste bin of what I'm intending to do:
http://imagebin.ca/view/WAe_koO.html

I really hope that someone will unblock me. Thank you for your time
and support.
Regards,
Édouard

[android-developers] Thread CPU Usage Monitoring

[dadical]

Is there a way to monitor the resource usages of a Thread in Android?
Resources of interest include CPU, memory, etc.  It doesn't seem like
ManagementFactory or ThreadMXBean are supported in Android. Are there
other options?

I would want to do this at runtime, from within a deployed
appolication, not just during dev/debug.

[android-developers] Re: CPU usage api's query

[dadical]

Is there any way to monitor CPU usage of a java thread from android?
It doesn't seem that android supports the ThreadMXBean or the
ManagementFactory.  What is available?  I noticed that Process offers
some very limited information, but I don't think that I can narrow
that down to actual thread usage -- it's just reporting process-level
information.

my application combines WebKit and "native" HTTP requests, so i've 
messed with this quite a lot. i never managed to successfully and 
reliably communicate cookies between WebKit and the Apache HTTP 
client. the cookies come out of the WebKit cookie manager in a 
convenient format to inject into any request, but it seems like the 
Apache client only occasionally takes notice of them. i've tried 
everything from dropping them into Apache's cookie jar to setting 
them as HTTP headers, all that.

going the other way might have more success, but in my application 
the WebKit has to establish the session. my solution was to get rid 
of the HTTP client from my application altogether and roll my own 
HTTP. since then i've had 100% success with cookie-sharing.

If you just change the brightness directly to what you want, the window
manager will do a smooth ramp from the current to your new brightness (as
much as it can with the hardware, many devices don't have a lot of possible
screen brightness levels).

[android-developers] Re: extending parcelables

[Dianne Hackborn]

We deliberately don't support this kind of thing to keep the IPC protocol
simple.  You have basically two choices:

1. Use a concrete class type, which will result in ONLY that classes CREATOR
being used to unmarshall its data.  The protocol does no type inspection
here, since that would introduce a lot more overhead to a very common
operation.
2. Use a generic Parcelable class type, in which case the marshalling code
will inspect the class type, included that in the marshalled data, and use
that to re-construct it on the other side.

You can also do your trickery in the CREATOR to instantiate multiple types.
If you have actually overloaded a method, then yes you will call through to
the most derived class.  This is purely a Java thing, and it certainly does
work; this kind of thing is done in a few places in the system.

[android-developers] Re: BATTERY_CHANGED not being sent for some reason.

[Richard Schilling]

Sounds good.  I can give that a try as well.

I did get good results by putting registeredBatteryIntent into a
service and registering the broadcast receiver there, since it's the
service that really needs to get the messages from the broadcast
receiver, and tends to stay active longer.

Thanks everyone for your help, especially Dianne.

In addition to helping me resolve the issue, process lifecycle (as
opposed to activity lifecycle) is much less of a mystery to me now.

[android-developers] Re: How to share files & shareUserId

When two applications shared the same user ID, they well have the same
identity.  They are indistinguishable as far as all permissions checks (both
on the filesystem and through IPC calls) go.

[android-developers] Re: how to find out the percentage of memory used by each process in the android

[Dianne Hackborn]

There is lots of memory sharing between processes, so this is actually a
really hard thing to determine.  For development purposes, the "procrank"
command is the most common tool to use.  The last two columns of memory
usage are the most interesting ones: the last one is the memory owned
exclusively by that process, and the second to the last is that plus the
shared memory weighted by how many processes are sharing each page.

Note that this command is not part of the SDK, and for format of its output
tends to change, so it should only be used for development purposes.

For even more detail specifically about Java processes, you can use "adb
shell dumpsys memoryinfo"

Hi Peli, maybe it's already done, but have you considered having this

options?

Cool, that sounds encouraging.

One final query, if I pursue the above mentioned course & improve the
build-in contacts app, then would I be able to build (make) the
improved contacts source code & get a Contacts.apk. If yes, then can I
distribute it as normal android app, which would run on any android
device?

Or would it be tightly coupled with the below android firmware & could
be distributed only along with the system.img


Ideally, this is what I am trying to do - Extend the existing contacts
app add additional feature make an improved Contacts.apk & release it
in the android market.

what say, possible?


Thanks for all your time.

I wish to have a receiver against latitude (instead of generic
location). Can this be achieved?

[android-developers] Re: ListActivity + CheckBox = bug ?

[Mark Murphy]

As Romain Guy pointed out, if you use choiceMode, Android *will* track
the checkbox states for you...but only if you have one checkbox per row.
I believe you indicated you had two, which is why I didn't suggest that
originally.

> what i don't understand through is that each checkbox have it's own
> checked value wich should be used by android when repaint is
> called ...

Why would it? Remember that Android is extensible, and there is no way
for Android to know which widgets have state that would need to be
persisted, or how necessarily to persist it. Only if *Android* is
putting the checkbox there (e.g., choiceMode) is it Android's
responsibility to track state -- if you put it there, it is your
responsibility.

HttpClient and WebView are completely separate engines. Operations done
in one will not affect the other.

If the Tumblr POST is setting a session cookie or something, you may be
able to get that out of the HttpClient cookie jar and feed it to
WebView, but I have not tried that.

[android-developers] Re: Build Contact "Stand Alone" apk - from Android Contact Source Code?

[Shibbs]

Ah sad ending to our over enthu project:

For the past few days, I have been searching like mad, like many other
developers from past who were trying to achieve something similar.
But, it was not very clear that we won't be able to do, with all
respect to your below comment I am stopping further development in
this regard.

Thanks once again!
