Check the various android:launchMode values for the activity element
in the manifest to see if one fits your situation.

[android-developers] Re: Move buttons within Layout

2010-02-17 Thread Kritzli

I'm still stuck on this problem. I tried to solve it by making the
whole activity dynamic. But still the button is positioned at top
left.
I can't see why

ok.layout(k.getLeft(), k.getTop(), k.getRight(),k.getBottom());

isn't repositioning the button, even if it shows the right Values on
LogCat.

I really need some help on that !

 Ok. Here's some more information about my App.
 I'm going to create a keyboard app. Or rather an App where you can
 define your own keyboard. Therefore I have two Activities A and B.

 Activity A:
 Here I want to create a single key. This is currently realized by
 configuring a button.
 The buttons size can be customized with a progress bar. One for height
 and one for width. Also some letters/text can be added.
 Then, height, width and the text of the button is send via an Intent
 to Activity B.

 Activity B:
 On Activity B the current Button gets its properties out of the Intent
 and via Gesture you can set it somewhere on the screen.
 Afterwards the button get saved in an Arraylist.
 Everytime I call Activity B the Arraylist is read and the buttons
 should be shown on their position as before defined.
 So the screen should be filled with buttons until the keyboard is
 ready.

 Then I want to create the keyboard (but I have no idea how yet ;) )

 But as mentioned before, after reading the Arraylist the buttons loose
 their position.

[android-developers] Example that redraws on a key without using a thread?

2010-02-17 Thread BobG

Howdy android experts. I thought I knew something about
programming lots of experience with microcontrollers and embedded
simulations that run in a loop and read inputs, do some calcs, send
outputs. After days of trying to write a program that prints out a
count that increments with a key, I guess I know nothing of how the
windows event driven model operates. I see examples that use another
thread/task/program to accomplish what I thought would be a couple of
lines. After the onCreate, lets say the screen says 'count 0'. The os
is now running. right? Any click or key should get 'delivered' to the
activity, so it seems I could have an onClick that says count++ and a
setText or something and an invalidate, and Bob's Yer Uncle, but
noo it aint that easy. I hereby declare that this task is
impossible, and no one can show me how to do it. (trying to use
reverse psychology as a motivational tool... thanks in advance)

Moving a widget requires altering the layout rules that control where

AFAIK, there are no upgrades to 2.1 for any Android device presently on
the market.

If you are using a modded firmware, please contact the source of that
firmware.

If this is your own firmware, as I indicated earlier, please ask your

If this is legitimate firmware from your device manufacturer or mobile

  -- Accuracy refers to how well the reported values reflect reality.

   If I am mistaken, which I hope I am, how would we go

  As far as I know, you can't. As Ms. Hackborn said, [10%] is just the
  precision the Droidbatteryreports.

   I have no problem getting single
   digit precision with other handsets only the Droid produces the
   strange '10's increments' only.

  That's the way Motorola elected to implement thebatterylevel
  information. The SDK does not mandate a minimum level of precision, so
  device manufacturers can report 1%, 10%, 3.14%, or whatever floats their
  boats. Applications (particularly paid ones) should not be relying upon
  some minimum level of precision, just as they should not be relying on
  certain LED colors or the availability of a physical CAMERA button.

  If you have more detailed questions on Motorola devices, I recommend
  asking Motorola the questions, since they have developer support boards:

[android-developers] Re: Custom BaseAdapter + dynamic updates = crash in ListView layout

2010-02-17 Thread whicken

I'm just trying to do a grouped layout - so a header would be followed
by a bunch of rows, then another header, and another bunch of rows.
They aren't collapsable, so I don't think it's quite an
ExpandableList.  As far as break points go, the only thing that seems
to be called before the crash is getCount.

I agree that the approach I've got here is all backwards, and I'm
going to simplify it into a single class - if I just use the flat
FancyAdapter (without the headers, naturally), then the crash goes
away.  So I think I'll just put support for alternate views into my
flat adapter to support the headers, and toss the Grouped adapter for
now.

I would like to know why it's crashing, though, as I may bump into the
problem again if I don't know what I was doing wrong in that code.

 Here's a question - what's the purpose of this adapter? What kind of layout

 reproducing the ExpandablistList functionality in a very strange way.

 First suggestion would be to stick a break point in every single function
 and see what gets called and in what order. Also throw in some logging to
 make sure your logic is correct in each and every function.

 Beyond that I would strongly suggest reworking this class. Maybe take a look
 at BaseExpandableListAdapter instead of the BaseAdapter? Or at least create
 an object that represents a single header with some sections and delegate
 some of the functionality to it instead of maintaining two lists and trying
 to do the indexing yourself in the one class. That's bound to get confusing.

I would still recommend the ExpandableListAdapter since it matches your
header + list of sections design. You can easily override the collapsing
behavior and remove the default expanded / collapsed icon so it looks like a
generic list.

This gives you the benefit of reusing that class that's already provided to
you, separating the header and section Views instead of having one giant
view containing both, and makes it easier to support clicking on the header
or individual sections. Plus the option to re-enable the collapse behavior
if you decide you need it down the road.

[android-developers] eclair 2.1 Lockscreen issue

2010-02-17 Thread techietone

hi all,
I  am running ecalir 2.1 codebase on samsung moment phone.
The issue is :

I  launch the camera app , press the endcall key , first the
lockscreen is created in landscape mode .
then i press the endkey again fastly , the OnResume() of camera app is
called and the lockscreen gets recreated in portrait mode after
getting onOrientationChanged() callback .

Now the issue is before showing the lockscreen , the camera activity
is shown first and then after 2 seconds the lockscreen is shown .
This issue is even occurring  with other apps (calendar etc).

Can anybody provide feedback in this regard ?

[android-developers] Re: Intent filters + prevent creation of multiple activity instances?

Hi Mark,

Yeah the problem is that my activity uses a singleton, and if there
are multiple instances of the activity, they can conflict with each
other if they are all trying to use the singleton simultaneously:

TaskA:
  ActivityB .. singleton.runLongProcess(...);

Browser:
  Click link, launch new instance of ActivityB
  ActivityB ..singleton.runLongProcess(...);

the other issue is that this activity can appear anywhere in the
activity stack of my app, so I'm cautious about using the singleTask
flag, which seems like the closest thing to what I need. Up until now,
I've just been using the:

  FLAG_ACTIVITY_SINGLE_TOP
  FLAG_ACTIVITY_CLEAR_TOP

flags within the app to make sure that there is only one instance of
ActivityB running.

I tried the following test which did not work:

 -Start ActivityA from app tray (launcher, singleTask)
 -Start ActivityB from button in ActivityA
 -Home screen
 -Browser
 -Click link
 -Intent filter calls ActivityA.
 -Since ActivityA is singleTask, the already running activity is
resumed.
 -ActivityA::onNewIntent() is called.
 -Try to start intent to also resume ActivityB instance:

Intent i = new Intent();
i.setClass(this, ActivityB.class);
i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);

that doesn't work though. The previous instance of ActivityB is not
restored, I just see ActivityB::onCreate() get called again, and this
second instance has a different memory address than the first one.

This is killer. I guess I could just make all of my activities
singleTask, but I know Dianne cautions against it and I don't want to
modify my app so profoundly by switching all the launchMode flags, I
don't know what side effects it will really have.

Thanks

[android-developers] how much time we have at onPause until we are killed?

2010-02-17 Thread guich

Hi,

When the user press the home key, the onPause method is called. At
this time, the application is supposed to save its state so it can be
properly recovered later.

However, and if the state is taking too much time? For example,
issuing a closeAllNetworkConnections that was waiting a feedback from
the server, or just if the amount of information we're writting to
disk is a lot of info... what would happen?

In my tests, i'm getting from 300-500 ms of time until the process is
killed.

Is there a safer place to put a save everything and quit code so
that it can safely save everything before a kill the activity task
is issued?

thanks!

[android-developers] trying to show a progressdialog in a lengthy task

2010-02-17 Thread guich

Hi,

When i first launch my main intent, i check if the application was
updated and, if yes, i decompress some asset files. This task can take
up to 15 seconds (to decompress a 6MB zip file).

So, i was trying to show a ProgressDialog to the user. However,
nothing in hell makes the dialog appear.

The lengthy method is called from onCreate. I already tried to put it
in onStart, but same thing. I also tried to run it in the ui thread,
same thing: no dialog appears, even if isShowing returns true.

This is the code:

showProgressDialog
while (...)
   // a 15-second task
nowQuit();

What can i do to make the dialog really show up on screen?

thanks

That depends on what state you are referring to. onSaveInstanceState()
is for data that is transient. onPause() might be a spot to save data
that is more persistent.

 that it can safely save everything before a kill the activity task
 is issued?

Yes: when the user pushes the Save button on the Save menu choice or
something, use an AsyncTask or IntentService to persist your changes.

Having the BACK button or something imply a save operation is OK when
everything is local. If you need Internet access, though, I would not
use the BACK button as the save trigger. After all, if you have no
Internet connection, you can disable the Save button/menu choice, but
you cannot realistically disable the BACK button.

In a pinch, fire off an AsyncTask or use an IntentService to persist
your data on an Android-supplied background thread. However, if you are
not finishing (i.e., isFinishing() is false), you probably also want to
cache that data locally, since you may need it in a few milliseconds and
should not be waiting both to persist the data to the Internet and then
read it back again.

Get your long-running work off the main application thread. Use an

    guich

in normal scenario your process is not killed everytime you finish
your activity, it's killed only when OS is short of resources.

if you observe your process to be killed by OS you dont have to care
about system resources like Sockets - they are going to be  closed by
OS

[android-developers] Re: Intent filters + prevent creation of multiple activity instances?

Ah I'm in the position where this code is out there, changing it so
drastically would be risky. It looks like there's just no way to
resume an already running instance, this doesn't seem right. I thought
this should be possible:

 App Tray
 ActivityA (singleTask)
   ActivityB (singleTop)

 Browser launch ActivityA
   ActivityA already-running-task is resumed
   ActivityA::newIntent(ClearTop | SingleTop, ActivityB.class)

shouldn't ActivityA just be able to wipe out the already-running
instance of B? I see the same instance of A is resumed by memory
address, so I am assuming its activity stack is also intact. But the
original instance of B somehow gets lost in limbo in the above
scenario, I never see ActivityB::onPause::isFinishing().

Thanks

 Instead of a pure singleton, use an IntentService or something else that

Anything *other* than lengthy tasks. The main application thread is the
UI thread.

 I really can't understand all the threads of Android...

There's only one thread of significance -- the main application (UI)
thread -- unless you arrange for your own threads, either manually
forking them or using tools like AsyncTask or IntentService.

[android-developers] Causing onMeasure() to be called for an EditView

2010-02-17 Thread poohtbear

Hi.
I've got a ported application that doesn't use Android UI (our list
screens and touch screens).
We a FrameLayout that contains two children a View (that we use to
paint on our UI) and an EditText which is usually invisible until we
have a test field that we want to use in our own UI.

To have our UI test field aligned with the android one, once the user
press on our list item we set the layout params to set it to the right
x and y (using margins) and the width and height, and request focus
for the EditText item.

This works great, however when resizing we always get the EditText
with the previous screen's orientation's LayoutParams.

A short test shows the reason: the layout calls onMeasure on itse;f
and the children, only then does onResize is called on the View which
resizs the list item we have in our UI, and only then the layout
params is being assigned to the EditText. Of course it already to late
as onMEasure was called already.

What i need is for the onMeasure() of he textEdit to be called once
the onSizedChanged() has finished.

How can i do that ?
I can create an ugly hack that if in the onLayout of the FramLayout
the EditText's dimensions are not like the measured ones the call on
setMeasuredDimension(int, int) to set the size i want.
This is a pretty ugly hack though and can cause a lot of instability,
so i'll appreciate other suggestions :-\

requestLayout() in the onSizeChanged() didn't help as well (tried in
the sizeChanged of the view, the layout and the EditText).

 I thouht I only can use them with FILL_PARENT, WRAP_CONTENT and

That's because you can't define a position with specific values.

Step #1: Design the layout in XML the way the widgets are originally.
You probably already have this already.

Step #2: Create an equivalent layout in XML the way the widgets will be
after your move.

Step #3: Figure out the right changes to LayoutParams, margins, and
whatnot to change your widgets, in Java, from the state the widgets
start in (Step #1) to the state you want the widgets in after the move
(Step #2).

You cannot just arbitrarily position widgets wherever you want -- their
position is dictated by their layouts.

Call getItem() on the ArrayAdapter, providing the position.

[android-developers] Photoshop CS4 workflow for Android UI design

2010-02-17 Thread OldSkoolMark

Been googling, but not finding relevant resources. Hoping the folks
here can help. I just received my copy of Adobe CS4 Web Premium and
have been messing around and reading the docs trying to determine what
the workflow is to create 3D UIs. As I don't have a 3d modeling
program so I'm interested in their support for taking multilayer 2d
graphics, building a 3d model from that, and allowing me to apply
lighting and texture effects to the result. Photoshop has most if not
all of this capability I think, but I'm not clear on how to proceed if
the 3d object you want isn't on the 3d menu.

The Adobe package comes with Illustrator and Fireworks too. Should I
use these programs to produce graphics and then import them onto
Photoshop layers for 3d processing?

Answers to these questions, or pointers to existing web resources, as
well as and any other advice with regard to using these Adobe tools
for Android UI design would be greatly appreciated

Re: [android-developers] Re: trying to show a progressdialog in a lengthy task

2010-02-17 Thread Frank Weiss

Hi Guich,

You're not alone in your misunderstanding of Android threading. However, if
you use AsyncTask correctly, you have a 99% chance of getting it right. Just
put any code that blocks, takes a long time, or can timeout into
the AsyncTask.doInBackground method instead of into an Activity method.

As an aside, the main UI thread is in way a lengthy task, but none of its
methods should be. This may be a generalization, but it should be idle most
of the time, ready to respond to user or lifecycle events.

Simple: get rid of the other activities. I really wish developers would

make the tabs be views in the TabActivity.

[android-developers] Re: Causing onMeasure() to be called for an EditView

2010-02-17 Thread poohtbear

Using the hack doesn't work.
if i call to the setMeasuredDimension() with the dimensions i want
from the onLayout() of the layout it wont change the measured values.

So i need some help here :-)


On Feb 17, 5:56 pm, poohtbear eyaltg...@gmail.com wrote:
 Hi.
 I've got a ported application that doesn't use Android UI (our list
 screens and touch screens).
 We a FrameLayout that contains two children a View (that we use to
 paint on our UI) and an EditText which is usually invisible until we
 have a test field that we want to use in our own UI.

 To have our UI test field aligned with the android one, once the user
 press on our list item we set the layout params to set it to the right
 x and y (using margins) and the width and height, and request focus
 for the EditText item.

 This works great, however when resizing we always get the EditText
 with the previous screen's orientation's LayoutParams.

 A short test shows the reason: the layout calls onMeasure on itse;f
 and the children, only then does onResize is called on the View which
 resizs the list item we have in our UI, and only then the layout
 params is being assigned to the EditText. Of course it already to late
 as onMEasure was called already.

 What i need is for the onMeasure() of he textEdit to be called once
 the onSizedChanged() has finished.

 How can i do that ?
 I can create an ugly hack that if in the onLayout of the FramLayout
 the EditText's dimensions are not like the measured ones the call on
 setMeasuredDimension(int, int) to set the size i want.
 This is a pretty ugly hack though and can cause a lot of instability,
 so i'll appreciate other suggestions :-\

 requestLayout() in the onSizeChanged() didn't help as well (tried in
 the sizeChanged of the view, the layout and the EditText).

[android-developers] onPause() not being called for singleTask finish()'d activity?

Hi,

I'm not sure why onPause() is not called in the following scenario.
Here's my activity:

// launchMode = singleTask

public class ActivityMain extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

Log.d($$, onCreate()... + getTaskId());
}

@Override
protected void onPause() {
super.onPause();

if (isFinishing()) {
Log.d($$, onPause()... + getTaskId());
}
}

@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);

Log.d($$, onNewIntent()... + getTaskId());
finish();
}
}

I launch my activity from the app tray, then hide it by hitting the
home key. So the app is running.
I then launch the browser, do a url-click action which should launch
this activity again (via an intent-filter).

I see the onNewIntent() method called. The task id and mem address is
the same as the original instance, so I know this is the original one
getting recycled. I do not see the onPause() method called though,
even though finish() is being called. Shouldn't the call to finish()
kill this one and only activity in this task?

The log output looks like this:

onCreate()...54
onNewIntent()...54
[missing onPause()...54]?

Thanks

Re: [android-developers] Re: Task activity stack always reset when launched from Home

2010-02-17 Thread Dianne Hackborn

When you say launch do you mean launching from Eclipse?  If so, there is a
bug in older SDKs where this would use the wrong intent so when you later
launch it from the launcher you would get a new task.

You can use adb shell dumpsys activity to see the current state of the
activity stack at whatever point you want to help diagnose what is going on.

 The code that starts the .About activity is:
protected void startAbout()
{
Intent aIntent = new Intent(this, About.class);
startActivity(aIntent);

 The Manifest entries for .UserLaunch and .About are in my original
 post.
 The intent that returns the task to the front is generated by the
 Launcher.

 What flags do I need to set (and where) to prevent this from
 happening? Is one of the default values causing it?

 My test case here is:
 1) launch .UserLaunch from the launcher
 2) start .About
 3) hit Home key
 4) launch .UserLuanch from the launcher

 There are no long delays in any of this, so the 30 minute auto-clear
 should not be invoked.

 I am just starting on an Android app and I am puzzled about why my
 Task activity stack is being reset any time the application is
 launched from the Home screen.
 
 I used the ADT tools to create the application in Eclipse.
 The main activity is .UserLaunch and it starts the activity
 .About
 when the user presses a button.
 If the user then presses HOME and then relaunches the app,
 .UserLaunch
 is displayed and is the only thing on the stack.
 
 .UserLaunch has the launchMode singleTask. .About is standard.
 According to the documentation at
http://developer.android.com/guide/topics/fundamentals.html#lmodes:
 
However, a singleTask activity may or may not have other
 activities above it in the stack. If it does, it is not in position
 to
 handle the intent, and the intent is dropped. (Even though the
 intent
 is dropped, its arrival would have caused the task to come to the
 foreground, where it would remain.) 
 
 The Task stack should be brought to the foreground and .About
 should
 still be displayed.
 
 I added Logging to all of the lifecycle events (edited to remove
 timestamps and shorten DEBUG/ and INFO/ to D/ and I/) and you can
 see
 that when HOME is pressed, .About cycles through onPause and onStop
 (as expected).  Then when the app is again launched, .About is
 destroyed and .UserLaunch is restarted

[android-developers] Re: onPause() not being called for singleTask finish()'d activity?

You're right, onDestroy() gets called - thanks again Mark.

  Hi,

  I'm not sure why onPause() is not called in the following scenario.
  Here's my activity:

  // launchMode = singleTask

  public class ActivityMain extends Activity {
      @Override

          super.onCreate(savedInstanceState);

          Log.d($$, onCreate()... + getTaskId());

          super.onPause();

          if (isFinishing()) {
              Log.d($$, onPause()... + getTaskId());
          }
      }

      @Override
      protected void onNewIntent(Intent intent) {
          super.onNewIntent(intent);

          Log.d($$, onNewIntent()... + getTaskId());
          finish();
      }
  }

  I launch my activity from the app tray, then hide it by hitting the
  home key. So the app is running.
  I then launch the browser, do a url-click action which should launch
  this activity again (via an intent-filter).

  I see the onNewIntent() method called. The task id and mem address is
  the same as the original instance, so I know this is the original one
  getting recycled. I do not see the onPause() method called though,
  even though finish() is being called. Shouldn't the call to finish()
  kill this one and only activity in this task?

 I don't think onPause() will be called, because you never got to onResume().

  Hi.
  I've got a ported application that doesn't use Android UI (our list
  screens and touch screens).
  We a FrameLayout that contains two children a View (that we use to
  paint on our UI) and an EditText which is usually invisible until we
  have a test field that we want to use in our own UI.

  To have our UI test field aligned with the android one, once the user
  press on our list item we set the layout params to set it to the right
  x and y (using margins) and the width and height, and request focus
  for the EditText item.

  This works great, however when resizing we always get the EditText
  with the previous screen's orientation's LayoutParams.

  A short test shows the reason: the layout calls onMeasure on itse;f
  and the children, only then does onResize is called on the View which
  resizs the list item we have in our UI, and only then the layout
  params is being assigned to the EditText. Of course it already to late
  as onMEasure was called already.

  What i need is for the onMeasure() of he textEdit to be called once
  the onSizedChanged() has finished.

  How can i do that ?
  I can create an ugly hack that if in the onLayout of the FramLayout
  the EditText's dimensions are not like the measured ones the call on
  setMeasuredDimension(int, int) to set the size i want.
  This is a pretty ugly hack though and can cause a lot of instability,
  so i'll appreciate other suggestions :-\

  requestLayout() in the onSizeChanged() didn't help as well (tried in
  the sizeChanged of the view, the layout and the EditText).

how you call setMeasuredDimension ?

do you use MeasureSpec.makeMeasureSpec ?

[android-developers] my EditText is an attention whore

2010-02-17 Thread DulcetTone

I have a ScrollView which features a variety of widgets --
ProgressBars, Spinners and Checkboxes and a single EditText way down
at the bottom.

If I am at the top of the ScrollView with the EditText scrolled way
off the bottom, touching and changing a ProgressBar at the top causes
the ScrollView to jerk all the way to the bottom to proudly show me
the EditText with a blinking cursor at the end of it. Toggling a
checkbox does not do this.

Why would this be?

I have no funky code around the EditText and do not try to alter it
programmatically after the context view is set.

The EditText is defined in XML as

EditText
android:id=@+id/my_edittext
android:layout_marginBottom=6dip
android:maxLength=6
android:minEms=4
android:inputType=phone
android:singleLine=true
android:textColor=#00
android:layout_width=wrap_content
android:layout_height=wrap_content/

[android-developers] Listview widget example

2010-02-17 Thread jotobjects

Thought this might be interesting for others.  Here is a bare bones
simple  ListView widget in a base Activity - NOT a ListActivity.
There is no explicit Adapter - it uses the android:entries attribute
to load the list data from a resource.  Probably not something you
would use in a real app, but maybe instructive for understanding the
ListViews.

--- MyListActivity.java ---
package foo.listview;

import android.app.Activity;
import android.os.Bundle;

public class MyListActivity extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mylistview);
}
}

--- res/layout/mylistview.xml ---
?xml version=1.0 encoding=utf-8?
RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
android

[android-developers] Re: my EditText is an attention whore

2010-02-17 Thread DulcetTone

More information:  this appears only to happen if I first scroll down
to reveal the EditText.
I notice that as I scroll the view by touch-drag, the EditText is
grabbing the focus as it breezes past (a behavior I could do without,
I suppose ... I'd be happy to insist on directly clicking on it.

I am guessing this is some adverse issue of focus, a feature I have so
far not had to directly consider.

[android-developers] Re: AudioTrack lag

2010-02-17 Thread Bob Kerns

The 70 ms here isn't due to the blocking nature, but due to the buffer
size. With a 2.5 ms buffer size, you'd be able to stop the sound in
5ms even when both buffers were full. It really has nothing to do with
blocking/non-blocking, which simply has to do with who has to do the
blocking and checking for buffers full/available.

I take it 70 ms is the minimum your hardware supports? If so, non-
blocking won't solve it, and you probably need different hardware. The
fact that they even HAVE a minimum suggests to me that we'e talking
about transferring to hardware buffers. Except for embedded devices,
it's been a long time since software wrote the DAC registers directly.

But what about that 500 ms? That would seem to be more under your
control. You can do your work in smaller chunks.

The scheduler is the other thing that'll kill you -- especially if you
had smaller buffer sizes. If you're doing work in other threads, you'd
want to tune it so you're doing work in small enough chunks that your
output thread can run in a timely way.

A non-blocking protocol does let you be more explicit about this --
essentially write your own scheduler.  But you can get the same result
with an audio pipeline approach, where you move small buffers of
data through each stage of your processing, in a single thread, and if
the UI sets a flag that you should be doing something different, you
just exit out of that pipeline wherever you are in the processing, and
start up the new pipeline.

If you want to try to use up more processor on the earlier parts of
your task, to protect against underruns, you can use two threads, with
a larger number of small buffers mediating between them. The smaller
buffers keep the initial latency small, while the larger number of
buffers still allows the upstream processing to get further ahead.

On Feb 16, 11:14 pm, Steve Lhomme rob...@gmail.com wrote:
 I can also say that a blocking AudioTrack would suck for a DJ software
 where 70 ms of latency to do an action is terrible. 5 ms would be
 acceptable, and that's also about as much time we use for polling.

 ...and because of the way our feeding
 threads work, it can take up to 500 ms between the time the user
 presses pause and the time the thread using AudioTrack is actually
 able to handle it.

[android-developers] Geocoder no longer works on new PC

2010-02-17 Thread shookie10

I have a problem getting the Geocoder to return results on my new PC
during development.  I started writing a android app on my other (Win
XP) system and Geocoder worked fine and returned locations based on an
address that I passed to it.

I recently bought a new PC (Win 7).  Moved the code over to it and now
the no address queries return any results.  I tried a couple that did
work on the xp machine, but are returning no results on the new pc.
It does not give any errors.

I did generate a keyfile on the old pc.  Do i need to create another
on the new pc?  Does the Geocoder require the key?  It is not from the
maps api.

[android-developers] can't display OpenGL and Camera together on nexus one/Milestone whereas it works fine on HTC Magic

2010-02-17 Thread Balbouch

Hello,

Most of you would think it's this question again... Well, my
application run perfectly (shows 3D model rotating with camera in
background) on the HTC Magic. But when I try to launch my application
on the Droid or the Nexus one, the only thing I can see is the camera
preview. If I delete the line when I add the camera preview
(addContentView) in my code, the OpenGL part works fine.

The worse is that sometimes everything working fine. And if I start
the application again it doesn't!

Here is the classic code:

mGLSurfaceView = new GLSurfaceView(this);
mPreview = new CameraView(this);
mGLSurfaceView.setEGLConfigChooser(5, 6, 5, 8, 16, 0);
mGLSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
mGLSurfaceView.setKeepScreenOn(true);
mGLSurfaceView.setRenderer(sceneRenderer);

setContentView(mGLSurfaceView);
addContentView(mPreview, new
LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));

Do you have any idea where the issue could come from?
Thank you in advance

[android-developers] OnActivityResult passing a null intent

2010-02-17 Thread Cog

Hi,
I'm trying to make a simple menu for adding another contact to a list.
On the ListView I have a button on a footer which uses
startActivityForResult to create a new menu (called add_dialog). This
is a simple EditText with an OK button and a Cancel button. The idea
is that clicking the OK button will pass the string from the EditText
back to the main Activity.

When the add_dialog Activity finishes and onActivityResult tries to
read the string extra it throws a null pointer exception.

The debugger gives the following line:
E/AndroidRuntime(  410): java.lang.RuntimeException: Failure
delivering result ResultInfo{who=null, request=0, result=-1,
data=null} to activity {com.test.hello_listview/
com.test.hello_listview.hello_listview}:
java.lang.NullPointerException

Can someone please explain why data is always null? Am I not using
getIntent().putExtra() correctly?

The source for the main Activity is:

public class hello_listview extends Activity
{
private Log logger;
private static final String TAG = hello_listview;

private String[] Pals;
private ArrayAdapterString adapter;
private Button addButton;
private String palName = ;
private static final int ADD_DIALOG = 0;
private static final int MAP_VIEW = 1;
Intent intent_addPal;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.palslist);
Pals = getResources().getStringArray(R.array.pals);
Arrays.sort(Pals);

ListView list = (ListView) findViewById(R.id.list);
adapter = new ArrayAdapterString(this, R.layout.listitem);
for (int i = 0; i  Pals.length; i++) {
adapter.add(Pals[i]);
}
list.setAdapter(adapter);

addButton = (Button) findViewById(R.id.addButton);
addButton.setOnClickListener(addButton_clicked);
intent_addPal = new Intent(this,
com.test.hello_listview.add_dialog.class);
}

OnClickListener addButton_clicked = new OnClickListener() {
@Override
public void onClick(View v) {
logger.i(TAG, add clicked);
startActivityForResult(intent_addPal, ADD_DIALOG);
}
};

@Override
public void onActivityResult(int requestCode, int resultCode,
Intent data) {
if ((resultCode == Activity.RESULT_OK)  (requestCode ==
ADD_DIALOG)) {

logger.i(TAG, add okay. data =  +
data.getStringExtra(PALNAME));// THIS LINE HERE

}
}

} // End of hello_mapview class


The source for the add_dialog Activity is:

public class add_dialog extends Activity {
EditText addText;
Button cancelButton;
Button doneButton;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

[android-developers] making videogame - newbie need help =P

2010-02-17 Thread Kofa

Hello, this is my first post, so sorry about the newbie thing lol.
Well, the problem is the next: I'm making a videogame of strategy, it
means i need an image (the background) that scrolls at the same time
with the objects on the screen (countrys, like RISK, TEG, EUROPA
UNIVERSALIS, .. but I can figure out how can do it. I mean, this
objects (the countrys) should be imageview or there is another view I
should use that it's better for interacting with the user, think in a
map of europe with every country selectable.
I was thinking of using an ImageView for the background and the other
objects on the screen to be imageviews too. Don't worry, I'm not
asking for code, just an idea of how?... and if it's not much to ask,
why?

Thanks!!

   3. For the SDK Location in the main panel, click Browse... and
locate your downloaded SDK directory.
   4. Click Apply, then OK.

What does locate your downloaded SDK directory refer to?  I can't
find the directory or file on my PC that the Eclipse interface is
referring to...

Thanks,
Sean

  Because this is a platform for smartphone. For example, if there has

  API test.

  If you have any information about it, please let me know :) Also if
  there has no information, how can I test some API to verify API.

[android-developers] Open input method automatically on showing Dialog

2010-02-17 Thread parthi

Hi,

I wanted to open input method automatically on showing Dialog, in my
Application. I created the dialog from layout xml and i have tried the
following.

1. Added android:windowSoftInputMode=stateAlwaysVisible|adjustResize
in the dialog's layout XML
2.  tried using InputMethodManager API.

 InputMethodManager
inputMethodManager=(InputMethodManager)this.getSystemService(INPUT_METHOD_SERVICE);
inputMethodManager.showSoftInput(ET.getRootView(),
InputMethodManager.SHOW_FORCED);

Both the approaches is not working. I seen the same behaviour for
preferences dialog well.

Is there any way to handle this?

[android-developers] Re: Moving the cursor to the beginning of an EditText

2010-02-17 Thread Kevin Park

You can do it like this.

EditText eidtText = new EditText(this);
// first, you set text and then..
editText.setSelection(1);
editText.extendSelection(0);
editText.setSelection(0);

 Using the following code, I am able to move thecursorafter the first

 Editable etext =editText.getText();
 Selection.setSelection(etext, 1);

 However, if I change it to Selection.setSelection(etext, 0) with the
 goal ofmovingthecursorto thebeginningof the text, it moves thecursor(or 
 doesn't move thecursor) to the end of the line instead of
 thebeginning.

 How can I move thecursorto thebeginningof the text?

 Hi All

 I wanted to get the info on the following query, could you guys please
 help me in getting the answer??

 I have set of platform api those will be tested byCTSto check
 compatibility, and I am making use of some 3rd party api in one of the
 platforms api. Suppose if I am changing or modifying the 3rd party api
 (to suit some of my requirement), isCTSis capable of telling whether
 compatibility is broken in  the 3rd party api??

 Example: Say i have api1, api2, api3…. Api n in our platform. In api3
 we have made use of  XyzThirdpartyApi.jar. And in XyzThirdpartyApi.jar
 we have done some modification to meet our requirement. AsCTStest
 each of the api to check compatibility is not broken, is there any way
 thatCTSinforms us compatibility is broken in XyzThirdpartyApi.jar??

 Or

 Is there any other tool to find out , compatibility is broken in the
 3rd party api’s (after any modification is done to suit our
 requirement)??
