You don't need task killers.  Some people like them, and who I am I to argue
with what people like? ;)

Re: [android-developers] About InputMethodService.switchInputMethod

[Dianne Hackborn]

Is the other input method actually enabled by the user?

Also you aren't clear where you are using this, but the API only works from
within the current input method.  It does not work for applications.

[android-developers] About InputMethodService.switchInputMethod

[a...@tw]

Anyone ever use this API: switchInputMethod?

I want to switch my IME from in my code.When I call this API,
sometimes the IME switched sometimes not.
When the requested IME not launched or display in the screen, the
original IME still remain in the screen, but cannot commit text into
the box.

Or another alternative way to do same thing ?

>From the comment in InputMethodService.java
/**
 * Force switch to a new input method, as identified by id.  This
 * input method will be destroyed, and the requested one started
on the
 * current input field.
 *
 * @param id Unique identifier of the new input method ot start.
 */
public void switchInputMethod(String id) { 

Does it mean we lost the connection between editor and IME?

Is there any procedure or prerequisite needed?

I found it also reported as issue#8725.

Re: [android-developers] Re: AlertDialog changes sequence of events

[Frank Weiss]

I strongly recommend you try to find some sample code at
developer.android.com that does something similar and follow that
example.

In other UI frameworks, there's a convenience function, such as
MsgBox() that accomplishes "blocking" the UI thread. I don't know
exactly how it's done, but I suspect it uses co-routines.
Unfortunately, I don't know how to do co-routines in Java, if that's
even possible.

I suggest two solutions: 1) completion methods, 2) state machine.

First is like this: start with this code sequence:

code section A // work done up to needing user input
block for user input
if (OK) {
code section B // work done for positive user input
}

refactor that (requires moving local variables to fields) to

methodA() {
code section A
}
methodB() {
code section B
}
methodA();
block for user input
if (OK) {
methodB();
}

then refactor that to: call methodB in the positive callback method of
the alert dialog instead of after the dialog.show().

The state machine approach is more general, and handles more complex
situations and is easier to modify than a rat's nest of completion
methods..

Nice, the dialog appear but DoSometing() crash for some reason.
At least the logic work, let me check on the DoSomething(). It was ok
w/o running as thread.

Many thanks.

Re: [android-developers] User thread to update UI but still come after, can anyone look at this code and help me?

[paulb]

Hello Mystique,

When this code starts the thread, it then goes straight back to
execute DoSomeTask() while the thread is running, and so most of the
time the dialog will be shown after DoSomeTask.

Maybe you meant to do something like this:

   ProgressDialog dialog;

  final Runnable runInUIThread = new Runnable()  {
   public void run() {
   dialog.dismiss();
   }
  }

  @Override
  public void onClick(View v) {
  // TODO Auto-generated method stub

  dialog = new ProgressDialog(CloseVault.this);
  dialog.setMessage("Please wait...");
  dialog.show();

  Thread myTask = new Thread() {
@Override
public void run() {
DoSomeTask();
handler.post(closeLoadingDialog);
}
};
  myTask.start();
  }


You are right, though, ASyncTask is a nicer way of doing it.

[android-developers] Re: Inner ListView not respecting layout gravity or width

[William Ferguson]

Sorry Mark, not sure what you mean.

I was using a nested ListView because for each instanve of the outer
list item there will be one or more instances of the inner.
In the example I am using the outer is Contact, and the inner is
RawContact.

When you say "stitch them together at the adapter level", do you mean
implement my own CursorAdapter that amalgamates 2 or more cursors?
How in my CursorAdapter implementation might I represent one or more
rows of the inner query other than using a ListVIew?

Eg from example given above.

Contact-1, Contact1-Name
   RawContact-1-a
   RawContact-1-b
Contact-2, Contact1-Name
   RawContact-2-z

[android-developers] User thread to update UI but still come after, can anyone look at this code and help me?

[Mystique]

Hi,
I'm trying to learn AsyncTask and Thread but Thread first...
I am trying to display a Dialog before "DoSomeTask()" but seems like
the Dialog always come after DoSomeTask().
Did I do something wrong here?

Thanks.

--- code---

   @Override
   public void onClick(View v) {
   // TODO Auto-generated method stub

   mainProcessing();
   DoSomeTask();
   }

   private void mainProcessing() {
   Thread thread = new Thread(null, doBackgroundThreadProcessing,
"Background");
   thread.start();
   }

   private Runnable doBackgroundThreadProcessing = new Runnable() {
   public void run() {
   backgroundThreadProcessing();

   }
   };

   private void backgroundThreadProcessing() {
   handler.post(doUpdateGUI);
   }

   private Runnable doUpdateGUI = new Runnable() {
   public void run() {
   updateGUI();
   }
   };

   private void updateGUI() {
   final ProgressDialog dialog = new ProgressDialog(CloseVault.this);
   dialog.setMessage("Please wait...");
   dialog.show();

[android-developers] Re: Anyone have reports of their app not drawing correctly on a Droid X?

[Maps.Huge.Info (Maps API Guru)]

I had several reports of my main app malfunctioning on the Droid X, it
was supposed to be a problem with panning. I managed to get my hands
on a unit to test the issue and it turned out to be nothing. From my
tests, the Droid X responds exactly like the Droid, same screen size
(pixel dimensions anyway) too.

It could be that the user is the one malfunctioning, it was in my
case. If your app tests out on the Droid, you are probably good to go.

[android-developers] Re: Android market link in SMS

[Warren]

I've got a partial solution to this.  If you use
http://market.android.com/search?q=pname:com.my.package  the url
works, but it does not automatically open with the market since other
applications, like the browser are also registered to handle http://
intents. Instead, the user has to know to choose the market.

No answers to his question? I also tried doing this with no success on
a Droid. I tried  "market://details?id=com.my.package"  and  "link"

Links with http://  need no special markup, they just work. For
instance, including http://www.google.com in a text message results in
the url being shaded blue. And when you click the link it opens the
browser as expected.

[android-developers] Re: Correct way to kill the application

[Mystique]

One question, not sure whether it is related.
Since Android manage task and application automatically and terminate
if necessary why do we need application like Advance Task Killer?
Isn't it redundant? I understand why Android was design this way, to
help speed up application and extra memory if not needed is just waste
so I rather have my app ready in the background and let Android decide
whether to close it.

Back to qns, why do we need ATK??? I have it install but I do not use
it anymore and doesn't seems to make a different.

Thanks TrekKing, I'm also doing more reading to do it correctly.
I think it is because the UI don't got refresh immediately unless I

[android-developers] Re: AlertDialog changes sequence of events

[john brown]

Does this mean that:
1) It is not possible for the AlertDialog to be made "modal" .
2) My implementation of the AlertDialog is not modal. Solve problem
with AlertDialog.IsModal = true; (or something like that)
3) or maybe:
   boolean buttonPushedFlag = false;
   AlertDialog.show();
   ..
  do while buttonPushedFlag = false {
   }

How do I accomplish what I need, a yes/no confirmation?

Thanks, John Brown

Re: [android-developers] How to identify which client called into a Remote/AIDL service?

[Dianne Hackborn]

Binder.getCallingUid() returns the uid of the calling who initiated the
current incoming call.

However more typically you'll use one of the flavors of these to just do a
permission check on the incoming call:
http://developer.android.com/reference/android/content/Context.html#checkCallingPermission(java.lang.String)

That function calls Binder.getCallingUid() for you and then does the
permission check with the system.

Actually it doesn't matter whether they have a rooted phone.  This is one of
the big reasons for moving to this over forward locking -- forward locking
requires trusting the device and its operating system to protect the app.
 With the new licensing model, the app does not need to have any trust in
the device it is running on or the market client app.  This gets rid of all
of the issues that forward locking has with apps not showing up on devices
that were not whitelisted/trusted.

[android-developers] Re: LVL security, are you sure that is secure, I'm a doubt in...?

[Eric F]

Most people aren't going to share their google account with someone
else just so they can get a $3 app for free. Who is realistically
going to give out access to:

A) Their email
C) Their credit card or payment method for Android market.

You lend your account to someone for a $3 app and suddenly they are
buying stuff as you. The bottom line is that piracy can never be
stopped. People can open up the .apk and fiddle the .dex files and get
an unprotected app. There's no stopping that. The point is with LVL
that normal people (probably 95%+) of the market don't have a rooted
phone. They have a stock Market app. It used to be that one hacker
with a rooted phone could distribute .apk files that install perfectly
on all non-rooted phones without difficulty. Now every .apk file will
have to be cracked first, for every update.

There is no true security, there is only added difficulty for pirates.
You must weigh the benefits of users getting annoyed that the app they
bought stopped working after they had to get their faulty phone
replaced several times from their carrier vs. some users all managing
to share the same google account on their phones. I feel that waging
war on your actual nice customers even just a little bit is way worse
than letting pirates do what they probably would find a way to do
anyways.

I'll be stunned if that works. Why nest ListViews? If your issue is
that you have multiple sources of data, stitch them together at the
adapter level.

[android-developers] Inner ListView not respecting layout gravity or width

[William Ferguson]

I have a ListView that contains several elements, one of which is
another ListView.
All elements of the outer ListView except for the inner ListView
respect their layout params.

The inner ListView respects margin left/right, but toally ignores
layout_gravity and layout_width.
Ie consumes the entire row sans the margins and is left justified.

I'd really like to have the inner ListView of the right hand side of
th screen.
I suspect its something obvious I am doing, but after several hours I
can't see it.
Any one got any ideas?

Here is the lauout for the inner ListView



Here is the config for the

http://schemas.android.com/apk/res/
android"
android:id="@+id/test_raw_contact_entry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"

[android-developers] Re: How to get handle to ImageView in a ListItem

[Hari]

Hi Greg,
I gave a thought to that approach as well. I want the image selection
dialog to come up only when the user clicks on the image view.

With onItemClick handler, the dialog pops up when user clicks any
section of the list item. How do i make sure that the dialog pops up
only when the user clickes on the Image.

Regards
Hari

[android-developers] Re: Text blinking effect TextView

[Zsolt Vasvari]

I can't give you code as I don't have any.  I simply suggested how I
would approach the problem.   Modify the existing code to, instead of
flipping to views, it hides and shows one.  You will have to do the
coding work, sorry.

[android-developers] Re: Retrieving XML Document from web service

[beacon]

Hello Frank,

This is what I am doing on the client side

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("token",WebPage.token);
SoapSerializationEnvelope envelope = new
SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.setXmlVersionTag("");
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject result = (SoapObject) envelope.bodyIn;
String strResult = result.toString();

I am getting all the fields that I am supposed to get, but I am not
getting it in the XML format.That's my problem.

[android-developers] Re: How to get handle to ImageView in a ListItem

[greg]

I also use the EfficientAdapter BaseAdapter in my ListView.  Is it not
possible for you to use the onItemClick handler, which provides the
list index (i.e., position), to implement your image change?  (That's
what I do.)

[android-developers] Re: adding audio to a game - triggerClip for SFX

[kk]

Dave,

Thank you for your quick response. SoundPool is indeed the right way
to go
and I've got my SFX playing...pretty straight forward interface.

A small problem I'm having is that during playback I get a lot of:

W/AudioFlinger(   31): write blocked for 50 msecs

Also, although my (relative short) SFX are playing, the background
music fails with:

E/AudioCache(   31): Heap size overflow! req size: 1050624, max size:
1048576

This same audio track worked fine with JetPlayer. Any idea why
SoundPool thinks it's too big?

cheers,
k.

[android-developers] Re: How to get handle to ImageView in a ListItem

[Hari]

Hi Mark,
Thanks for the Reply.

I might have not stated my question properly.

I have implemented another functionality for onListItemClick().

Each list item has a ImageView and i want the user to be able to
change this image by selecting from phone's gallery or by taking a
snap. So i have an onClicklistener() for the image view. How can i
know which ListItem was clicked? I also would like to update the
database for this ListItem to save the image byte[] in blob column.
For this reason i have to know the item that was clicked.

Regards
Hari

[android-developers] Re: Retrieving XML Document from web service

[beacon]

Thanks for your reply. But it is not similar to JSON. My sample data
looks something like this

anyType{ProductName=anyType{Text=Nadolol; Code=anyType{Value=11755;
CodingSystem=FDB_routed; }; Code=anyType{Value=20.55472;
CodingSystem=Google; }; Code=anyType{Value=7870; CodingSystem=FDB; };
Code=anyType{Value=19.9453; CodingSystem=Google; }; }; }

And I have confirmed with the web service and they have assured that
they send back the data in XML format. But I am not able to get it in
XML format.

[android-developers] Multiple calls to SimpleCursorAdapater#bindView

[William Ferguson]

Hi all, I have a ListView populated using a SimpleCursorAdapter that
has a ViewBinder, and I'm finding that when the ListView is displayed,
ViewBinder#setViewValue is called 3 times for each row of the cursor.

Once during onMeasure:
at au.com.xandar.contactsmanager.DisplayContactsActivity
$1.setViewValue(DisplayContactsActivity.java:56)
...
at android.view.View.measure(View.java:8171)
at android.view.ViewRoot.performTraversals(ViewRoot.java:801)
at android.view.ViewRoot.handleMessage(ViewRoot.java:1727)
at android.os.Handler.dispatchMessage(Handler.java:99)
at android.os.Looper.loop(Looper.java:123)
at android.app.ActivityThread.main(ActivityThread.java:4627)
at java.lang.reflect.Method.invokeNative(Native Method)
at java.lang.reflect.Method.invoke(Method.java:521)
at com.android.internal.os.ZygoteInit
$MethodAndArgsCaller.run(ZygoteInit.java:868)
at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:
626)
at dalvik.system.NativeStart.main(Native Method)

Once during onLayout:
at au.com.xandar.contactsmanager.DisplayContactsActivity
$1.setViewValue(DisplayContactsActivity.java:56)
...
at android.view.View.layout(View.java:7035)
at android.view.ViewRoot.performTraversals(ViewRoot.java:1045)
at android.view.ViewRoot.handleMessage(ViewRoot.java:1727)
at android.os.Handler.dispatchMessage(Handler.java:99)
at android.os.Looper.loop(Looper.java:123)
at android.app.ActivityThread.main(ActivityThread.java:4627)
at java.lang.reflect.Method.invokeNative(Native Method)
at java.lang.reflect.Method.invoke(Method.java:521)
at com.android.internal.os.ZygoteInit
$MethodAndArgsCaller.run(ZygoteInit.java:868)
at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:
626)
at dalvik.system.NativeStart.main(Native Method)

And the third time from onMeasure again.

Firstly, is this expected behaviour?

If it is, then what's the best way of performing potentially expensive
work in ViewBinder#setViewValue?
For example, retrieving the results of another cursor whcih is used to
construct the bound view.

Or am I approaching this from entirely the wrong view point?

William

[android-developers] Re: Correct way to kill the application

[Eric F]

Yeah this is exactly what I thought too. Just because non-technical
people download task killers from the market doesn't mean that task
killers are necessary. In my opinion it is way more likely that the
explanation is that people are just very bad at shifting their way of
thinking from paradigm to paradigm.

And it also made me think of the windows tuner programs. I've noticed
a trend in the way people think these days. I call it the do-nothing
dilemma. We are incapable of doing nothing these days. What I mean is,
when we look at a problem we instantly act for the "solution". Because
we are so advanced these days that we are just used to things being
already solved somewhere by someone, somehow. I am only 30, but I
suspect that people living in the 1920s had more of a grin and bear it
mentality ("man up") when it came to problems and hardship.

Now, whether it's a kid hurting him/herself on a swing and people
needing to "Do Something", banning swingsets from all playgrounds. Or
a cellphone chugging along while syncing contacts, people don't think
"huh, my cell phone is not as quick as I want it. Oh well I'll just
deal, it's still a great phone and I'm sure in the future we'll have
faster phones that don't slow down". They think "Wow, surely there
must be someone to blame for this and someone with the fix. Oh here
this task killer allows me to solve my problem". Soon they are
probably having more problems than they started, but they don't care
because now everytime they get disgruntled they can "do something"
about it. And nobody wants to admit that they are administrating
themselves placebos, so feeling like it *is* a valid solution is self
reinforcing.

That was a bit long winded. But I agree with Kostya, I don' think
people downloading task killers from the marketplace show a deficiency
in the OS. Only a deficiency in the way people adapt to new things.

Obviously the pre-bundled apps that can't be uninstalled are a huge
problem. task killers not really being a good solution there, the real
solution is root -> uninstall. Hopefully Google will be able to nudge
companies in the right direction. I doubt we'll ever be in a crapware
free world, but perhaps they can be convinced to make crapware
uninstallable.

[android-developers] Retrieving XML Document from web service

[beacon]

Hi ,

 I am trying to retrieve a XML document from web service. I am passing
a soap object with a token implementing the OAuth concept and
retrieving the data. But the data does not turn out to be in XML
format. It contains a curly braces in the place of start tag and
semicolons when it ends. Is there any way to retrieve the document in
XML format as such?

Thank you

Beacon

[android-developers] Re: add to application via Java code

[Paul Turchenko]

Behind the curtain, android uses permissions to asign you user groups
he belongs to (linux user and linux groups). So basically you are
asking if you can add user assigned to your application to certain
groups. Guess that's not possible as your process (meaning your user)
just doesn't have permissions for that. So you end up having no
permissions to set a permission :)

[android-developers] LVL security, are you sure that is secure, I'm a doubt in...?

[sblantipodi]

Hi all,
I'm implementing LVL...

I noticed that google recommends to not use devicelimiter,
but what are the meaning of licensing if you not use devicelimiter?

Probably I missunderstood something but without device limiter piracy
is easyer than before...
Suppose that I bought XXX software using an ACME account created for
this purpose, than I share username and password of this account to
let others pirating the XX software.

What is that I missunderstood ?
It can't be so easy...

[android-developers] Static variables cleared in JUnit tests! (???)

[Streets Of Boston]

Hello,

I have this test-code:
=
package somepackage;

import android.test.ActivityInstrumentationTestCase2;
import android.util.Log;

import com.kronos.mobile.android.Constants;
import com.kronos.mobile.android.ExceptionsSummaryActivity;
import com.kronos.mobile.android.test.utils.KronosSolo;

public class ExceptionsSummaryActivityTest extends
ActivityInstrumentationTestCase2 {
private static String USER = "tturner";

public ExceptionsSummaryActivityTest() {
super("somepackage", ExceptionsSummaryActivity.class);
}

@Override
protected void setUp() throws Exception {
super.setUp();

Log.v(Constants.LOGTAG, "Setup for "+getName()+" "+USER);
}

@Override
protected void tearDown() throws Exception {
super.tearDown();
}

public void test010ResetData() throws Exception {
Log.v(Constants.LOGTAG, "Testcase for "+getName()+" "+USER);
}

public void test020LoadDataFromHome() throws Exception {
Log.v(Constants.LOGTAG, "Testcase for "+getName()+" "+USER);
}

public void test030UIElements() {
Log.v(Constants.LOGTAG, "Testcase for "+getName()+" "+USER);
}
}
===
The JUnit is a separate Unit Test application (apk), running another
APK (the one under test).

When I run the above test-code (all the code is shown, nothing has
been left out), the value of USER changes magically from "tturner" to
'null'. In test010ResetData and the setup of this test, the value of
USER is "tturner". In the other test-method (and their setup() calls),
the value of USER is null.
Ouput:
  Setup for test010ResetData tturner
  Testcase for test010ResetData tturner
  Setup for test020LoadDataFromHome null
  Testcase for test020LoadDataFromHome null
  Setup for test030UIElements null
  Testcase for test030UIElements null


When i change this line to (adding 'final)'
 private static final String USER = "tturner";
the value of USER remains "tturner" for all test-methods!
Output:
  Setup for test010ResetData tturner
  Testcase for test010ResetData tturner
  Setup for test020LoadDataFromHome tturner
  Testcase for test020LoadDataFromHome tturner
  Setup for test030UIElements tturner
  Testcase for test030UIElements tturner



When i then change that line to (changing String to Object, still
using 'final'):
 private static final String USER = "tturner";
the value of USER is again 'null' in test020 and test030!!
Ouput:
  Setup for test010ResetData tturner
  Testcase for test010ResetData tturner
  Setup for test020LoadDataFromHome null
  Testcase for test020LoadDataFromHome null
  Setup for test030UIElements null
  Testcase for test030UIElements null


My question is:
Why and how are static variables (e.g. USER) of JUnit test-cases set
to null?
Is this correct behavior.

I tried in on a G1 running 1.6 and on a Nexus1 running 2.2. They both
have the same behavior.

Re: [android-developers] AlertDialog changes sequence of events

[Kostya Vasilyev]

AlertDialog is not "modal" - the call to show() returns immediately, leaving
the dialog on the screen and button callbacks active.

This is the reason for the sequence change you're seeing.

[android-developers] AlertDialog changes sequence of events

[john brown]

Hello,

The following code runs as I expect it to.: (cntr is an int with the
whole class as it's scope)

System.out.println("before saveReading, cntr = " +
Integer.toString(cntr));
saveReading(Integer.parseInt(etRead.getText().toString()));
System.out.println("after saveReading, cntr = " +
Integer.toString(cntr));

public void saveReading(int reading){
System.out.println("In saveReading before ++, cntr = " +
Integer.toString(cntr));
++cntr;
System.out.println("In saveReading, after ++, cntr = " +
Integer.toString(cntr));
}

after the code runs, LogCat shows the following System.out:

System.out  before saveReading, cntr = 0
System.out  In saveReading before ++, cntr = 0
System.out  In saveReading, after ++, cntr = 1
System.out  after saveReading, cntr = 1

This (above) is the sequence of System.out events that I am expecting.

//

If I change the code to include a AlertDialog Yes/No for confirmation
of the ++cntr, the code looks like this:

System.out.println("before saveReading, cntr = " +
Integer.toString(cntr));
saveReading(Integer.parseInt(etRead.getText().toString()));
System.out.println("after saveReading, cntr = " +
Integer.toString(cntr));

public void saveReading(int reading){
System.out.println("In saveReading before ++, cntr = " +
Integer.toString(cntr));
AlertDialog.Builder bldr = new AlertDialog.Builder(this);
bldr.setTitle("Confirmation Required") ;
bldr.setMessage("Save this reading?");
bldr.setPositiveButton(R.string.YesButton, new
DialogInterface.OnClickListener(){
//@Override
public void onClick(DialogInterface dialog, int which) {
///code for YES (increment cntr)
++cntr;
}
});

bldr.setNegativeButton(R.string.NoButton , new
DialogInterface.OnClickListener(){
//@Override
public void onClick(DialogInterface dialog, int which) {
// code for NO (do nothing, cntr remains the same)
System.out.println("no!!!");
}
});

bldr.show();
System.out.println("In saveReading, after ++, cntr = " +
Integer.toString(cntr));
}

When I run the code, the AlertDialog Yes/No routine looks like I want
it to look but the following LogCat output shows that the sequence of
events is not what I was expecting. It looks like all the code in the
code block containing the call for saveReading, including saveReading,
runs and then the code in saveReading runs.

after the code runs, LogCat shows the following System.out:

System.out  before saveReading, cntr = 0
System.out  after saveReading, cntr = 0
System.out  In saveReading before ++, cntr = 0
System.out  In saveReading, after ++, cntr = 1

What can I do to make the code with the yes/no confirmation run in the
sequence I am expecting, i.e. like the first LogCat output?

Thank you very much for your help. John Brown

Re: [android-developers] Re: Froyo -- How to detect that my application has been killed?

[Dianne Hackborn]

It isn't being called because the app is NOT being restarted.

As I said, the ONLY thing app killers can do now is the same thing that the
OOM killer does when it needs memory, and this NEVER involved a broadcast.

You have lost nothing here from previous versions of the platform.

A handful of Android devices may have built-in radio tuners. I suspect
none have built-in radio tuners and also have activities with a
documented means for other applications to launch a radio station. I'm
not saying it's a bad idea, but I'm just skeptical that anyone has
done it.

[android-developers] How to populate a ViewStub using different ImageButtons?

[Victoria Busse]

Hi there,

I am trying to populate a ViewStub with a new view depending on which
ImageButton is clicked, but as I just discovered ViewStubs I am not exactly
sure how this would work...

e.g. can I provide the ViewStub with different inflatedIds and within the
onClick event of a Button inflate the ViewStub by calling a specific
inflatedId???

If someone could give me hand, that would be really great.

Thank you very much in advance :o)

Google should worry more about the crap-ware vendors are putting on my phone.

Allowing vendors to interfere with my battery life is definitely a bad thing.

My EVO basically lives on a charger.  I carry a spare battery around
for when I am physically separated from a way to charge my phone for
more than 6 hours.  :(

Leave the task killers alone.  Kill the crap-ware that makes the task
killers necessary.

[android-developers] Re: How to identify which client called into a Remote/AIDL service?

[mah]

I don't know if there's a more proper way to do what you need, but it
makes sense that there should be.

In the worst case though, you can solve this through your own
protocol... you can require clients call an initialization to receive
some random value you provide (and store, to associate with them), and
all of your other entry points can require that this value be among
the parameters.

Re: [android-developers] Re: Correct way to kill the application

[Kostya Vasilyev]

Technical details aside, I think it's just human nature.

Some percentage of users just have a strong desire to have something 
"magical" that *supposedly* makes their device (Android phone or desktop 
OS) work much better.


Remember - there used to be all kinds of memory optimizers for Windows? 
Also registry cleaners, various "tweak" and "tune-up" utilities, etc. 
etc. etc. No-one is saying that Windows (or any other OS :) is perfect, 
but these apps promise much more than they actually do, and sometimes 
cause harm.


There is also a whole subculture of users who root and flash their 
phones - I am convinced most do it because it addresses some 
psychological need, more than anything else.


So personally, I am quite happy to see that Google is starting to limit 
what task killers can do. I believe interfering with the platform's core 
functionality is definitely a bad thing.


I have enough bugs in my code to have to deal with someone else's.

A good article. A little harsh on the OP, but even so, a good article.

After all: given that that IS the design of Android, that Applications
should not quit, but leave termination up to the OS, the article makes
its case well, even elegantly.

But I cannot help but notice: after Android did all that hard work of
designing the whole system to work that way, what does the market say
about it? The presence of so many "Task Managers" for Android seems to
imply that the Market does NOT agree with this paradigm.

Nor would that conclusion really surprise me, since it is a basic
expectation, almost an instinct, even predating computers: if it
doesn't work, you want to hit Reset, or power-cycle the device, and
you expect that it will be in a known good state (note the terminology
reminiscent of s certain OS with its "last known good"). Exiting an
application is the software-analog of shutting the power off: you
expect that the next time you enter, you get a clean slate.

True, WebOS doesn't work that way either, and Android's way is a new
trend. But I don't see the market approving this in WebOS either --
even if it does like it better than Palm's previous OS, Palm OS. For
Palm OS was ugly.

Besides: despite all the claims otherwise ("just let the system do
it"), I _have_ come across circumstances when I really do want to just
exit everything to get the phone to behave again. Surely I am not
alone, which is why people download the Task Managers for Android.

[android-developers] Re: Froyo -- How to detect that my application has been killed?

[tomei.ninge...@gmail.com]

Hi Dianne,

Our main problem is that Intent.ACTION_PACKAGE_RESTARTED is no longer
called in Froyo.

(Sorry I digressed to Service ... I thought that I can implement
something similar to Intent.ACTION_PACKAGE_RESTARTED by running a
service from my app. If the app is killed, the Service can detect that
the app is killed -- by checking the length of its callback list --
and then take appropriate clean up actions.)

Anyway, we used to listen to Intent.ACTION_PACKAGE_RESTARTED to do
clean ups. But on Froyo, when an app is killed using
killBackgroundProcesses, we don't get any notification.

This is a pretty big incompatible change (as I mentioned above, you
see left-over icons in the status bar from killed apps).

Is this an intentional change in Froyo?

Thanks

[android-developers] Re: Binder is leaked by binding to a service

[brucko]

This appears to be a bug

http://code.google.com/p/android/issues/detail?id=6426

watch out. If your LocalBinder is a non-static inner class, then you
will leak your Service as well as non-static inner classes have a
reference to the outer class.

expectation, almost an instinct, even predating computers: if it
doesn't work, you want to hit Reset, or power-cycle the device, and
you expect that it will be in a known good state (note the terminology
reminiscent of s certain OS with its "last known good"). Exiting an
application is the software-analog of shutting the power off: you
expect that the next time you enter, you get a clean slate.

True, WebOS doesn't work that way either, and Android's way is a new
trend. But I don't see the market approving this in WebOS either --
even if it does like it better than Palm's previous OS, Palm OS. For
Palm OS was ugly.

Besides: despite all the claims otherwise ("just let the system do
it"), I _have_ come across circumstances when I really do want to just
exit everything to get the phone to behave again. Surely I am not
alone, which is why people download the Task Managers for Android.

[android-developers] Re: Multiple Sliding Drawers

[brucko]

Disclaimer - I have no idea about what I am talking about. I have not
tried this.

Could you use one sliding drawer with three views on the handle - but
change the drawer contents based on what part of the handle was
touched to drag up. To make it a better user experience, you might
make the handle section become the whole handle when it is touched?

Good luck.

Re: [android-developers] Extending multiple classes

[Priyank Maiya]

Hi,
I am facing some when running the code. I am using the
getApplicationContext() to save the instance.
Kindly have a look at my code and let me know where I am going wrong.

VVMService is the class whose instance is created and got from the
onServiceConnected() callback

public class VVMServiceBind extends Activity
 {
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
bindService(new Intent(VVMServiceBind.this, VVMService.class),
mConnection, Context.BIND_AUTO_CREATE);
VVMService appState = ((VVMService)getApplicationContext());
   }


public void onServiceConnected(ComponentName className, IBinder
service)
 {
Log.i(TAG, "In onServiceConnected");
 mService = ((VVMService.VVMBinder)service).getService();
 appState = mService;

}
}


VVMClientApplication is the class where I need to access the VVMService
class instance.

public void serviceConnectionSuccess()
{
private VVMService mService;

mService = (VVMService)getApplicationContext();

  }

dont I have to extend Application in any class ?

Thanks,
Priyank

[android-developers] Re: Subclassing Animation

[jsera]

Alright, invalidate seems to just call onDraw, which is exactly what
the docs say it does, so my approach is to call setMeasuredDimension
in the method called by the Runnable posted by the tick, (It seems
like onMeasure only gets called if the dimensions are changed by
setMeasuredDimension, so if you only set the dimensions in onMeasure,
nothing happens.) then call getParent().requestLayout(). (This means
setMeasuredDimension gets called twice.)

I want my View to overlap other views at certain times, so I'm
guessing that I'll have to mess around with the View's LayoutParams,
and adjust the margins as well.

Re: [android-developers] Re: Froyo -- How to detect that my application has been killed?

[Dianne Hackborn]

Oh wait I take that back...  what has changed is that task killers no longer
go through the full force stop path -- *ALL* they can do is kill processes,
and further only processes that are good or moderate candidates for the out
of memory killer (pure background processes up to services running in the
background).

So to look at API demos -- if I use that and "Remote Service Controller" to
start the remote service, then use a task killer to kill API demos, what
I'll see in the log is that the two processes are simply killed, just like
the OOM killer would do:

I/Process (  101): Sending signal. PID: 668 SIG: 9
I/Process (  101): Sending signal. PID: 641 SIG: 9
W/ActivityManager(  101): Scheduling restart of crashed service
com.example.android.apis/.app.RemoteService in 5000ms
I/WindowManager(  101): WIN DEATH: Window{44ea7520
com.example.android.apis/com.example.android.apis.ApiDemos paused=false}
I/WindowManager(  101): WIN DEATH: Window{44d500f8
com.example.android.apis/com.example.android.apis.ApiDemos paused=false}
I/WindowManager(  101): WIN DEATH: Window{44d994d0
com.example.android.apis/com.example.android.apis.ApiDemos paused=false}
I/WindowManager(  101): WIN DEATH: Window{44eae490
com.example.android.apis/com.example.android.apis.app.RemoteService$Controller
paused=false}
D/dalvikvm(  291): GC_EXPLICIT freed 484 objects / 24352 bytes in 61ms

And then a little later I correctly see that the remote service is
restarted, just as happens if the process is killed by the OOM killer:

I/ActivityManager(  101): Start proc com.example.android.apis:remote for
service com.example.android.apis/.app.RemoteService: pid=695 uid=10062
gids={3003, 1015, 1006}

Compare that with the output of an actual force stop which the task killers
can no longer do:

I/ActivityManager(  101): Force stopping package com.example.android.apis
uid=10062
I/Process (  101): Sending signal. PID: 695 SIG: 9
I/Process (  101): Sending signal. PID: 712 SIG: 9
W/ActivityManager(  101): Scheduling restart of crashed service
com.example.android.apis/.app.RemoteService in 5000ms
I/ActivityManager(  101):   Force finishing activity HistoryRecord{44f23740
com.example.android.apis/.app.RemoteService$Controller}
I/ActivityManager(  101):   Force finishing activity HistoryRecord{44d43428
com.example.android.apis/.ApiDemos}
I/ActivityManager(  101):   Force finishing activity HistoryRecord{44d91560
com.example.android.apis/.ApiDemos}
I/ActivityManager(  101):   Force finishing activity HistoryRecord{44d2e2c8
com.example.android.apis/.ApiDemos}
I/ActivityManager(  101):   Force stopping service ServiceRecord{44eacb00
com.example.android.apis/.app.RemoteService}


For the behavior you are seeing, are you using the bind server instead of
the start service UI?  If you do that then yes your service will not be
restarted -- because the process that is bound to it is in the background,
so free to be killed, and once it gets killed the binding goes away and the
service does not need to run any more.

But this exact behavior is expected to happen when the device is low on
memory, so it is something apps need to deal with correctly anyway.

No that is a totally different thing.  All installed apps have a private
data directory, non-forward-locked, forward-locked, on-sd, or whatever else.

Um yeah the check for process priority does let it kill service processes
(not visible or foreground service processes though).  Whoops.  I'll fix
that.

That said, the service *does* restart like it always did, and I have
confirmed it does.  That code path hasn't changed at all.  So basically the

that can unintentionally be killed.

AFAIK, the app's local files (e.g., getFilesDir()) is still in the
on-board flash, not on the SD card, even if the app is installed to
the SD card.

[android-developers] Webview not fit to screen

[Ken]

Hi,

When I load a URL in my webview, the page always appears with full
size and I am unable to zoom out (I did call
setBuiltInZoomControls(true)). The webview is wrapped in a
LinearLayout with fill_parent for both dimensions.

Is there a simple way to fit the content of the webview automatically
to the screen? Thanks!

Ken

Does this mean that apps installed on SD card are not going to be able to

Re: [android-developers] Adding headers to listview for cursor with grouped results

[Connick]

I'm with you on that ...re: header part of hierarchy, that's the direction
I'm going but I was worried about position mapping ...you're suggestion to
include the header view with a row item would solve that problem!
Gracias, will give that a shot.

You don't need to use minSdkVersion; you should use targetSdkVersion to say
you are Froyo compatible, and devices on 2.2 and up can install it on the SD
card.  This doesn't make you incompatible with older platforms.  (In fact
you don't need to do that -- you can set min/target SDK to whatever you
want, and just need to compile against the 2.2 SDK so you can use the new
manifest attribute.)

Putting an app on SD card with 2.2 doesn't prevent others from reading it.
 In fact, as the announcement about the licensing server says, we are moving
completely away from forward-locking (read-protecting) apps.

If apps feel the need to protect their data, they can encrypt it themselves.

[android-developers] Re: Can't get LVL working.

[sblantipodi]

Now I've got another problem now...
I'm using the Default Policy implementation,
the first time I setted my developer console to licensed,
this makes my software authenitcate well on the emulator, after this,
I setted the developer console to not licensed, removed the software
from emulator and reinstalled it.
Now when I start software it tell me that the software is licensed
also if I setted the developer console to not licensed...

Any Idea?

Thanks.

Re: [android-developers] Re: Subclassing Animation

Something like that :) The way we usually do it is post a delayed
invalidate instead of using a Timer. We'll have a better solution in a

Re: [android-developers] Adding headers to listview for cursor with grouped results

[Kostya Vasilyev]

It does on my phone - Samsung Galaxy S with Android 2.1update1. This is 
the built-in Android email client, set up with an IMAP account.


I just had an idea.

It should be much easier to implement the header as part of data item 
view hierarchy. This way the number of items in the list view is exactly 
the same as the number of items in the cursor, and you can avoid extra 
code dealing with counting data items and mapping their positions.


You'd have two kinds of list item views - one with the header, one 
without. Deciding which one to use is pretty simple - in the adapter's 
getView, compare the item's data with the previous item's. If they 
differ, you need to use the version with the header.


-- Kostya

30.07.2010 22:44, Connick ?:
The grouping itself is no problem ...its tossing in the arbitrary view 
to act as a header to each group within that list. From the looks of 
the client it doesn't use any type of headers in its list ...but 
thanks for the suggestion!

Thanks for the quick reply!

So then would the best approach be to call invalidate, and change the
size of the View using setMeasuredDimension on every tick of a Timer
object?

A handful of Android devices may have built-in radio tuners. I suspect
none have built-in radio tuners and also have activities with a
documented means for other applications to launch a radio station. I'm
not saying it's a bad idea, but I'm just skeptical that anyone has
done it.

Re: [android-developers] Subclassing Animation

Subclassing Animation won't help you unfortunately. It would be best
for you to implement the animation yourself.

Re: [android-developers] Adding headers to listview for cursor with grouped results

[Kostya Vasilyev]

Stacy,

You might want to look at the source for Android's built-in email 
client. It groups messages by date, i.e. "today", "yesterday", "more 
recent".


Don't know for sure if its source is available, but I think it is (K9 
mail is based on it).

I suspect that would be troublesome, since Cursor objects know their

You can do headings with a single Cursor -- my sleep-deprived brain

Re: [android-developers] Sync Adapter and api level 3 & 4?

Yes permissions on older platforms will be ignored.  Since older platforms

Do be sure of course to test your code on an older platform to be sure all
is well, though.

[android-developers] Re: My experience with LVL and the precedence it sets

[andrew android]

I just started using the LVL also.  I had problems adding a reference
to the LVL project (I kept getting manifest errors immediately upon
adding the reference) so I just added it directly.  Then, I tried to
buile the sample code into my project but I find it all very
"clunky".  I think it is absurd to not take the time to build methods
and properties that automatically can set obfuscation properties,
obtain device Id, make a call to do the validation and such.  Having
source code is mice but they really should have made this quicker to
implement with the option to customize and do more with it or to not
and take a simpler approach.  I was so looking forward to using this
but am sorely disappointed.  There is a competing android market with
a much better licensing implementation, by the way.

Re: [android-developers] Extending multiple classes

[Kostya Vasilyev]

This is called "multiple inheritance", and Java - the language - doesn't 
have this feature, regardless of the platform (Android or not).


Break up your code logic into more fine-grained pieces. You can bind to 
the service from multiple activities, as many as necessary.


Also, you don't need to explicitly create Service objects - this is done 
for you by the Android framework, when you either bind to a service, or 
just start it.

[android-developers] Subclassing Animation

[jsera]

Hi, I'd like to subclass Animation in order to get an animation that
changes the clipRect of the canvas passed to a particular custom view
instead of messing with the matrix of that canvas.

The reason for this, is that I want to animate a partially obscured
bitmap up to display it fully.

So, say I have a bitmap 100x100 px, and at the start of the animation,
I want to start out displaying the top 100x50px of it, so the clipRect
will be of the size 100x50.

I want to move the clipRect 50px up, and add 50 px to it's size, but
it looks like both the scale and translate animations just change the
matrix, so I wind up displaying the same 100x50px area, but stretched
to fit in in whatever space.

Anyway, what's the best way of accomplishing this?

[android-developers] Sync Adapter and api level 3 & 4?

[Mark Wyszomierski]

Hi,

I'm looking at the sample sync adapter here:

  http://developer.android.com/resources/samples/SampleSyncAdapter/index.html

I'd like to still support sdk level 3 and 4 devices. Will including
the following lines in my app's manifest be problematic?:

  
  

are these specific to sdk level 5?

Ideally, we could include these for level 3 and 4 users, and they just
won't be shown the contact sync option at all. Is this how it's meant
to work?

Thanks

I want to test the doCheck() method that tell me if the app is

This should work ok on the emulator. Am I wrong?

Use a service, static data members, or a separate custom Application class.

[android-developers] Re: Froyo -- How to detect that my application has been killed?

[tomei.ninge...@gmail.com]

Dianne, here's the reproduction step on Froyo:

[1] Run on Froyo - start ApiDemos, start the RemoveService sample. You
will now see two processes
com.example.android.apis
com.example.android.apis:remote

[2] You will notice that "Sample Remote Service" appears on status
bar.

[3] write an app with KILL_BACKGROUND_PROCESSES permission. Call

 
ActivityManager.killBackgroundProcesses("com.example.android.apis");

[4] Both processes created at step [1] are killed.

[5] RemoveService is never restarted, even though you see something
like

W/ActivityManager( 2426): Scheduling restart of crashed service
com.example.android.apis/.app.RemoteService in 2ms

[6] "Sample Remote Service" message still stays on status bar. This is
because StatusBarService expects a ACTION_PACKAGE_RESTARTED broadcast,
but
this braodcast is never delivered.

What's the best way to handle this -- we need to clean up some
resources if
the app process is killed.

Thanks!
