[android-developers] Re: DEVELOPER CHALLENGE 2 - Can update of existing published app can participate?

[havexz]

Can any one from Google reply to this ...as time is passing
everyday?

 I M NOT A GOOGLE REPRESENTATIVE.THESE ARE MY PERSONAL VIEWS

 What I think that Google is not allowing published apps:
 - Published apps are more mature as they are live apps.
 - Published apps are coded way before so they have more set of
 features.
 - They want the apps for DC2 be built with in a month or two time
 frame.

 If they put restriction on these basis then a developer who is working
 for a long time on android platform should be competing with a
 developer who just started to develop for the DC2.

 * One more suggestion is that they can put a limit on time for
 which the application is published. Say application should be
 published before six months or something

 * Another suggestion is they create a new category for published
 apps and all published apps compete that category.

 * The last suggestion which i mentioned earlier also, that there
 has to be substantial difference between the feature set to be
 eligible for DC2

 What I feel that published apps be treated the same way as un
 published ones.

[android-developers] How to get Mimetype from extentions? (.txt/.vcf)

[ylx_presid...@hotmail.com]

Hi,

I am trying to get Mimetype from extention for .txt file, using below
method:
MimeTypeMap map = MimeTypeMap.getSingleton();
type = map.getMimeTypeFromExtension(extension);

But the returned type is always null.

Looking into MimeTypeMap.java code,  in function loadEntry(), I found
below codemsg.
private void loadEntry(String mimeType, String extension,
boolean textType) {
..
// here, we don't want to map extensions to text MIME types;
// otherwise, we will start replacing generic text/plain and
// text/html with text MIME types that our platform does not
// understand.
//
if (!textType) {
mExtensionToMimeTypeMap.put(extension, mimeType);
}
}

Per above codes, all text series extentions (like txt, rtf, text,
vcf...)  can not get Mimetype using the getMimeTypeFromExtension()
function.

Is there any other way to get Mimetype for *.txt or *.vcf file?

Thanks,
ylx

[android-developers] Re: READ_CALENDAR and WRITE_CALENDAR

[Kaj Bjurman]

Is there somewhere where we can see when it's scheduled for release?

Several people have told me that they don't like the Calendar widget
since it only displays the next upcoming event. It would be far better
if it could be configured to display the X next upcoming events within
a given horizon. E.g display maximum 5 events, but only if they are
within the next 2 weeks.

I thought it sounded pretty easy to create a widget that did that, but
it's kind of disappointing that it isn't possible right now :(

 Complains about what? The code you posted tries to read the entire file and

 has limited scope), there would not be anything left for it to read.

The front part of the values of the longitude will be the values of

I think that there is a bug about saving the gps attributes.

BTW, Does anyone has any idea about this topic?
There are few article around this topic on the internet...

[android-developers] ContentObserver _id - SMS, Contact Media

[Shibbs]

Hi All,

From the past two days I have been closely reading through the
ContentObserver discussion on the various scenarios like:
1.) SMS sent
2.) Contacts updated
3.) Media added.
4.) etc...

We all are aware that the onChange() of the ContentObserver() doesn't
notify us to what has been changed for obvious reasons.

We thought of coming up with a logic, though it is not fully proof,
just wanted to discuss the solution with you guys:

The scenarios we deal with here are:
1.) Last SMS Sent
2.) New Contacts added.

We had a close look at the db structure of the Contacts, SMS  Media.
They all have this primary column name - _id which is
autoincremental. Currently the limit of this stands at a whoofing:
9223372036854775807. (2^63)

each time a new contact has been added to contacts.db or new SMS sent
(record added to ( SMS db)) it is bound to have the greatest _id
value if the above limit (9223372036854775807)  has not been reached
yet.

Then in onChange()
1.) Filter out if the event is a new contact changed or SMS sent
{ simple logic posted in previous some post)
2.) If yes, then query and get the last record based on the ascending
order of _id value (default order) you can get the desired last SMS
sent or New contact added.

Note: This logic is not full proof, cause over a period of time if the
_id crosses 9223372036854775807, then this logic would fail or I
guess so.

Not sure what Android would do internally once the id crosses
9223372036854775807?
Will it start from -9223372036854775808.

Any better solution?


Thanks,
Shibbs

[android-developers] Re: drawRect not doing anything in a 1.5 MapView

You'll need to do fillPaint.setStyle(Paint.Style.FILL) I think.

 I'm having a problem getting drawRect to draw anything on a Canvas

 between 1.1 and 1.5 I'm not taking into account?

 The relevant code is as follows (in snippet form):
 (R.color.graticule_fill is #10FF; Graticule is an object that
 indicates a 1x1 degree area on the earth's surface)

 Context mContext; // comes in from constructor

 static Paint fillPaint = new Paint();
 fillPaint.setColor(mContext.getResources().getColor

 Graticule g) {
         // This method is called from draw(); c is passed in from
 there,
         // pr = mapView.getProjection(), g is provided by the class.
         if (g == null) {
             return;
         }

         // Two Points, the top-left and bottom-right of the graticule,
 taken from the
         // current Projection
         Point topleft = pr.toPixels(g.getTopLeftGeoPoint(), null);
         Point bottomright = pr.toPixels(g.getBottomRightGeoPoint(),
 null);

         // Should draw out a rectangle covering the graticule; this
 works in 1.1, but

 (sorry if this snippet doesn't make much sense out of context, I can
 provide more information if need be)

 AFAIK, there is no way to inspect the file system on a normal (i.e.,
 non-rooted) production device. That means you cannot browse it with DDMS.

 At least for debug-compiled apps, I used to have success using adb pull
 to directly reference a file and download it off the device, though I
 haven't tried that since Android 1.5 was released.

ex:Intent intent = new Intent(java3.this, java1.class);

[android-developers] Re: how to close activity?

[tstanly]

eg:
2.java has a variable s:
private String s;
i changed value probability,

but now,
when 3-1,i want to destroy 2 and kill variable s,
that means,
when back to 1 from 3,the s is null.

[android-developers] Re: how to close activity?

[Rock]

Hi...

  You are declared as private String s; So s variable cannot
access in 1.java 0r 3.java.. So
make the s variable declared as public static String s; So now you can
access variable in 1.java 0r 3.java
So assign value s=;

Thank You

[android-developers] SoundPool doesn't play sounds 100K in SDK 1.5

[Katsiaryna]

Hello,

I am trying to use SoundPool class from the new SDK. However, I
discovered that if I load sounds that are 100K (120K and 350K) from
resources I have problems playing them. The error messages that I get
are as follows:

06-23 10:53:42.263: ERROR/AudioFlinger(35): not enough memory for
AudioTrack size=1048640
06-23 10:53:42.263: DEBUG/MemoryDealer(35):   AudioTrack (0x25018,
size=1048576)
06-23 10:53:42.263: DEBUG/MemoryDealer(35): 0: 0002aaf0 |
0x | 0x00090940 | A
06-23 10:53:42.263: DEBUG/MemoryDealer(35): 1: 0002ab78 |
0x00090940 | 0x0006F6C0 | F
06-23 10:53:42.263: DEBUG/MemoryDealer(35):   size allocated: 592192
(578 KB)

Consequently, the playback never starts.

Curiously, the numbers in the message do not seem to change with sound
files of different sizes: whether it is 120K or 350K, it always says
not enough memory for AudioTrack size=1048640. Also, when I load the
sounds I see numerous messages in the log saying 06-23 10:53:35.743:
ERROR/AudioCache(35): Heap size overflow! req size: 1052672, max size:
1048576.

So, is there any official size limit on the size of the files you
can play, or are there any settings to adjust to solve this problem?
The test application where I get this doesn't actually do anything
else but loads and tries to play these sounds, so I do not think that
it is the problem of it using too much memory overall. I also tried
both .ogg and .mp3 files - equally without any success.

Any help would be much appreciated,

---
Best regards,
Katsiaryna

[android-developers] How to get a view from a custom layout ?

[Guian]

I've created a custom view via .xml file,
and I wanted to add it as a a contentView to an alert Dialog usinf a
dialogBuilder:


AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setNeutralButton( _Res.getString(R.string.close), new
DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int which) {
myDial.dismiss();
}
});
builder.setCancelable(true);
builder.setIcon(R.drawable.my_icon);
builder.setTitle(R.string.title);

builder.setView(   HERE I SHOULD USE myCustomLayout   );
builder.create();

TextView text = (TextView) myCustomLayout.findViewById(R.id.goTotext);
text.setText(toto);
... etc...

builder.show();



The problem is...  I can't get my view from my custom layout...
I only have an  id (int)...

I tried Resource.getLayout(int) = it returns an xmlParser... not very
usefull ...

finally the solution I comes up is so disgusting ( it worked but ...
let's have a look)

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setNeutralButton( _Res.getString(R.string.close), new
DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int which) {
myDial.dismiss();
}
});
builder.setCancelable(true);
builder.setIcon(R.drawable.my_icon);
builder.setTitle(R.string.title);

Dialog tmpDial = new Dialog(this); // create a tmp dialog ...
tmpDial.setContentView(R.layout.settings_dialog); // put my
custom layout as the content view of the tmp Dialog

View tmp  = (View)tmpDial.findViewById(R.id.setting_dial_lay); //
get my layout as a View ...
tmpDial.setContentView(new View(this)); // set a new content
View to the tmp dial to remove my view from his parent... (so sad
isn't it ?)

builder.setView(tmp); / here I have my view ready to be used
but isn't it really disgusting ... ??
builder.create();



... so guys,  how can I do that easily without using such a disgusting
way... ?

[android-developers] Drawing custom images in a ListView

[android-developers] No context menu on map view intended??

[Binesy]

Hi

Having been working with context menus with other views, which can be
done with

view.setLongClickable(true);
registerForContextMenu(view);

this does not seem to be the case with map view.  Is this intended??
Also overlays only seem to be able catch onTap events, is it possible
to catch long press events on these?

Many Thanks

Ross

[android-developers] Re: Errors In Android Run time I need suggestions

[Urs Grob]

Ok ..counting by hand I think this is the 31st line:
findViewById(R.id.cmdCalculate).setOnClickListener(new OnClickListener() {

So I guess findViewById(R.id.cmdCalculate) returns null.

Is there a definition for cmdCalculate in your main layout? (if there
is, there's maybe a typo?)

That's not the right design. Instead look into the alarm manager, you
want an inexact repeating alarm to send an intent to your service so
your process only runs when it's actually working. Make sure that
stopSelf() is always called, even if the process is killed half way
through the download!

The code is mostly from last summer's M5 SDK, and so these posts are a

 ... so guys,  how can I do that easily without using such a disgusting

Use LayoutInflater, obtained via getLayoutInflater() from your Activity.

[android-developers] Re: Errors In Android Run time I need suggestions

[Desu Vinod Kumar]

Hi

Yes absolutly correct that cmdcalculate button invoking webservices when i
press that button it is quitting

i am not getting how to solve
this

 Ok ..counting by hand I think this is the 31st line:
 findViewById(R.id.cmdCalculate).setOnClickListener(new OnClickListener() {

 So I guess findViewById(R.id.cmdCalculate) returns null.

 Is there a definition for cmdCalculate in your main layout? (if there
 is, there's maybe a typo?)

[android-developers] Re: ContentObserver _id - SMS, Contact Media

[Peli]

Don't worry about reaching the limit 9223372036854775807.

Even if you insert 1000 new entries per second into your database, it
will take you 290 million years until you reach that limit
( 9223372036854775807 / 1000 / 60 / 60 / 24 / 365 = 292 471 209 )

(dinosaurs died out 65 million years ago; the G1 would be a fossil by
that time:

 Hi All,

 From the past two days I have been closely reading through the
 ContentObserver discussion on the various scenarios like:
 1.) SMS sent
 2.) Contacts updated
 3.) Media added.
 4.) etc...

 We all are aware that the onChange() of the ContentObserver() doesn't
 notify us to what has been changed for obvious reasons.

 We thought of coming up with a logic, though it is not fully proof,
 just wanted to discuss the solution with you guys:

 The scenarios we deal with here are:
 1.) Last SMS Sent
 2.) New Contacts added.

 We had a close look at the db structure of the Contacts, SMS  Media.
 They all have this primary column name - _id which is
 autoincremental. Currently the limit of this stands at a whoofing:
 9223372036854775807. (2^63)

 each time a new contact has been added to contacts.db or new SMS sent
 (record added to ( SMS db)) it is bound to have the greatest _id
 value if the above limit (9223372036854775807)  has not been reached
 yet.

 Then in onChange()
 1.) Filter out if the event is a new contact changed or SMS sent
 { simple logic posted in previous some post)
 2.) If yes, then query and get the last record based on the ascending
 order of _id value (default order) you can get the desired last SMS
 sent or New contact added.

 Note: This logic is not full proof, cause over a period of time if the
 _id crosses 9223372036854775807, then this logic would fail or I
 guess so.

 Not sure what Android would do internally once the id crosses
 9223372036854775807?
 Will it start from -9223372036854775808.

 Any better solution?

 Thanks,

[android-developers] Re: how can i launch the intent to pick image from SD card?

I presume the video list activity has not been implemented
cooperatively enough for  ACTION_PICK.

An alternative is to try to use ACTION_GET_CONTENT, which is taken
better care of usually.

 But I only get a listView which shows the text of the video file name.
 And when I click on it, the video plays.

 How can i get it to show a 'preview thumbmail' of each video? (like of

[android-developers] Problem with a AndroidManifest.xml for a service

[GAYET Thierry]

Hello,

I have used the Eclipse IDE for starting an Android Service but i have one 
problem with my AndroidManifest.xml file on the line of the service tag.

Here is my AndroidManifest.xml :



package=com.OrangeLabs.gbaAndroid.BootstrapService
application
activity class=.BootstrapService android:label=@string/app_name
intent-filter
action android:value=android.intent.action.MAIN /
category android:value=android.intent.category.LAUNCHER /
/intent-filter
/activity
   service class=”.BootstrapService”/ -- my problem is here !!
/application
/manifest 

And my Service skeleton :


package com.OrangeLabs.gbaAndroid.BootstrapService;


import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
import android.os.Parcel;
import android.widget.Toast;

//Need the following import to get access to the app resources, since this
//class is in a sub-package.
import com.OrangeLabs.gbaAndroid.BootstrapService.R;

// @brief Main class for the BootstrapService Android service
public class BootstrapService extends Service 
{
// Actions to perform when service is started.
@Override
public void onStart(Intent intent, int startId)
{
// Test the TelephonyManager API (can we have an access to the 
authenfication
// function buildin the sim/usim card



// Create the shared memory used between the bootstrap client and the 
// application in link with a NAF server

// Check and wait until the WIFI become usable


} // onStart

// Initialize variables, get references to GUI objects
@Override
public void onCreate()
{



} // onCreate
@Override
public IBinder onBind(Intent intent) 
{


return null;
} // onBind
} // BootstrapService



Is there a place where i can view / download some services sample ?

[android-developers] Use own map layer in Google Maps

[JP]

Hi All,

I have a GIS layer, that holds information about some areas. It is
basically a rating for a specic area. So each shape defines a specific
rating.

I would like to be able to add this layer to Google Maps and then in
my Google Android phone be able to open a little application that just
shows that rating based on your current location as a big number on
the screen.

I am fairly new to Android development, so I don't know the Google
Maps API that well yet.

I would be very happy for any pointers in the right direction and even
happier if anyone could present an example!

Thanks,
JP

 Not built in, no. Your choices are to try a Java FTP JAR, or see if

 Curiously, the numbers in the message do not seem to change with sound
 files of different sizes: whether it is 120K or 350K, it always says
 not enough memory for AudioTrack size=1048640. Also, when I load the
 sounds I see numerous messages in the log saying 06-23 10:53:35.743:
 ERROR/AudioCache(35): Heap size overflow! req size: 1052672, max size:
 1048576.

 So, is there any official size limit on the size of the files you
 can play, or are there any settings to adjust to solve this problem?
 The test application where I get this doesn't actually do anything
 else but loads and tries to play these sounds, so I do not think that
 it is the problem of it using too much memory overall. I also tried
 both .ogg and .mp3 files - equally without any success.


That 120KB mp3 is decoded in to memory by SoundPool, and will expand to
something much bigger.
The exact numbers depend on the bitrate, sample rate and number of channels,
but as an example, a 100KB, 128kbit mp3 has a playback time of over 7
seconds, and if it's 44KHz stereo it will be about 1.3 megabyte when
decoded.
SoundPool is meant for short, sound effect style sounds that require very
low latency and low CPU overhead. For longer sounds, you should use
MediaPlayer.

[android-developers] Re: how to close activity?

[Marco Nelissen]

To close 2 when going from 3 to 1, use the CLEAR_TOP flag in
startActivity().
To kill the variables, just set them to null in the activity's onDestroy.

 not only close the 2,

[android-developers] Re: 6502 Emulator

[LouisB]

fadden, thanks for taking a looksy into the emulator.  Great ideas for
optimization BTW.  I've been looking at your ideas plus this document
(http://slack.net/~ant/nes-emu/6502.html) and wondering how much mhz I
can squeeze out of her.

 How are you determining performance?
Mhz is calculated by counting clock cycles per loop.

Might be pessimistic, but I'm thinking the G1 hardware is just too
slow.  It's at 1/3 mhz right now, and even if I squeeze another 1/3rd
out I'm still at .66Mhz.  The last 1/3 would probably be more trouble
than the time is worth (or impossible.)  I'm leaning heavily towards
waiting for the hardware to catch up.

Do you know anything about the NDK?  Would it allow me to do C
language type operations to speed this up?  i.e. get the JVM out of
the way and go straight to the cpu / memory?

 BTW, at some point you'll want to add support for a virtual keyboard.
 Not all devices have physical keyboards, which makes it tough to get
 things going.

True - I could use the built in one correct?

[android-developers] Re: Use own map layer in Google Maps

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

You could call a Google API based map that uses a custom tile layer or
other type of overlay as a webkit page directly from an Android
application. The easiest way to do so would be to use a parameter
based positioning method, another words, pass the coordinates of
interest to the map via lat and lng parameters to the page. It's not
too hard to do this, nor is it too difficult to create a page with a
custom tile overlay, putting it all together requires a lot of little
things so if you're new to both Android and Google Maps API, then
figure at least a month or two of hard work to understand the dozen or
so pieces of the puzzle.

Here's a link to a parameter based map that essentially does what
you're looking to do with a whole image overlay instead of a custom
tile layer.

[android-developers] Re: Copy SQL lite Database to Device (and not emulator)

[burton miller]

you can export it to file, then read that file in at run time.

however, if you are going to package the data with the app, i
recommend just putting the database in your assets, and copying it to
the database directory when you start up.  it won't take long
(compared to downloading from the net), and it is easier.  either way,
you waste the space.

how big is your db?

Picturefiles are never ascii.

However, to anwser the first part as where the files are saved: In
Windows VIsta they are stored in

or
C:\Users\YourWindowsUsername\AppData\Local\Android\SDK-1.0

but there are only image files inside, which you can't directly edit.

Nitpick: you're running the emulator, not the simulator.

The real reason I want to find the files is because I am downloading

 an png file and trying to create a bitmap via: Bitmap bitmap =

 However, the bitmap is always null.
 I am able to create a bitmap successfully if I have the file as a

Can you access the file otherwise? I.e. can you open and read the file

[android-developers] Re: Possible bug when extending themes

 The word ''@drawable is not correctly spelled

 But that is nonsense!
 I check the styles.xml that comes with android and found the following

 However even this gives me the error message?!!@

[android-developers] Build apk from command line

[sumd]

Hi,

 Is is possible to build apk with jar, Manifest.xml, and res
directory?

 I've a jar file with one activity. Application which will use this
jar can come from external.
I'm not giving my jar file to the app developer. I would like to build
an apk which includes my jar, application jar, application manifest
and resources.
According to this thread
http://groups.google.com/group/android-developers/browse_thread/thread/11aa21996839cef5/9d3d978fdfcd48e9?hide_quotes=no,
we can't include resources and manifest in a jar.
 My goal is to edit the manifest to list my activity (the one inside
jar) and make it as a launcher activity, and build apk with
application jar, resources and my jar. I understand ant needs other
things like build.xml and project properties.

Is there any other way to build apk from command line with jar,
manifest, biuld.xml and resources?

Thanks,
sumd

[android-developers] Spinner to play sound.

[KoZinE]

Hi,

I am currently doing an application which will play a sound from a
selection via a spinner. I've tried many ways but I still cannot get
it to play a sound.

Here is my code for the constraints and spinner.

// List-based Constants
public static final int HAPPY = 0;
public static final int LAUGHTER = 1;

//code for spinner
Spinner s = (Spinner) findViewById(R.id.SoundSpinner);
ArrayAdapter adapter = ArrayAdapter.createFromResource
(
   this, R.array.Sounds,
android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);
s.setAdapter(adapter);
s.setOnItemSelectedListener(OnItemSelectedListener);

Spinner.OnItemSelectedListener OnItemSelectedListerner
= new
OnItemSelectedListener() {
public void onItemSelected(AdapterView parent,
View v, int idNum,
long id) {


switch (idNum){
case HAPPY:
  Music.play(this, R.raw.happy);
break;
case LAUGHTER:
Music.play(this, 
R.raw.laughter);
break;

 }
 }
 public void onNothingSelected(AdapterView
arg0) {}
 };

I know android's spinner does not respond to setOnItemClickListener.
However, when I changed it to onClick, I get confused with the code
and the application quits by itself when I run it on the emulator. Can
anyone help me? Thank you so much! (:

  Possibly. You can go either way. I usually assume separate activities
  until something forces my hand to go to multiple pages in one activity.

[android-developers] onRecieve starting activity problem

[ani]

Guys,

I would like to know the reason behind this behaviour.I have a
broadcast reciever and in onrecieve i am trying to start an
activity,however if i am not giving the flags it is giving an
exception .On declaring the flags it is working perfectly fine,why?

I was under the impression that onRecieve runs in the main UI thread
and we can launch an activity in onRecieve.Error given by the emulator
is self explanatory but still why do i need to create an activity in a
new task(only in onRecieve)?

onRecieve {
Intent intent4activity2 = new Intent
(android.intent.action.activity2);
//intent4activity2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
arg0.startActivity(intent4activity2);
}

regards,
ani

[android-developers] Re: how to call Camera application from my own application

[N0m0r3l13s]

Hi.

I suppose there must be an Intent to call the camera app.

Other thing is if you want to capture video directly from camera.
The best way you can do it is analyzing the camera application that
comes from
google. And follow up the steps to set it up in you program.

Sorry, cannot help more.

Guys,

I was under the impression that onRecieve runs in the main UI thread

new task.Why do we need to create a new task and launch the activity
there.Why cant the activtiy launch in the task in which main UI thread
is running?

[android-developers] Google map does not work.

[Jack]

Hello all,

I'm new to android and need some help. I'm creating a basic Mapview
application which will display my current location on the google map.
Initially i had many doubts while creating the application, but thanks
to google archives that helped me to reach this point. I
have followed almost all the threads on the google site
but still unable to see my location on the google maps. It always
shows a white screen on the emulator with google image at the bottom.
Please help to make it work. From most of the threads I learn that we
need to sign our application with the correct fingerprint. I did so
but unsuccessful.

The following will explain the steps:
1. Using sdk version android-sdk-windows-1.0_r1
2. Created a new android application.
3. Signing the application:
a. C:\Program Files\Java\jdk1.6.0_13\binkeytool.exe -list -alias
androiddebugkey -
keystore D:\Profiles\fknq86\Local Settings\Application Data
\Android\debug.keyst
ore -storepass android -keypass android
b. Certificate fingerprint (MD5):
75:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:33
where XX=some alpha numeric data
c. signing up for an Android Maps API key! using link
Sign Up for the Android Maps API - Android Maps API - Google Code
4. Code below: There are 2 applications 1. Find Me 2. ShowMyLoc.
FindMe has a button which directs it to ShowMyLoc (using Intent) to
show the location on the google maps. For simplicity sake i'm pasting
the code only for ShowMyLoc app.

//ShowMyLoc.java
Code:

package org.anddev.android.findme;

import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;

import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;

public class ShowMyLoc extends MapActivity {
   private Location myLocation;
   protected MapView myMapView = null;
   protected LocationManager myLocationManager = null;
   protected MapController mapController;

   @Override
   protected boolean isRouteDisplayed() {
   // TODO Auto-generated method stub
   return false;
   }

   @Override
   protected void onCreate(Bundle icicle) {
   // TODO Auto-generated method stub
   super.onCreate(icicle);
   this.myMapView = new MapView(this,
0ZFOV5MY-5tIiNoVa_UiMuiMf39w_N6T5DalZzg);

   this.setContentView(myMapView);

   mapController = myMapView.getController();
   mapController.setZoom(15);

   this.myLocation = new Location(gps);
   this.myLocation.setLongitude(77.52436144125092);
   this.myLocation.setLatitude(13.05096452223662);
   updateView();
   }

   private void updateView(){
   Double lat = myLocation.getLatitude();
   Double lng = myLocation.getLongitude();

   GeoPoint point = new GeoPoint(lat.intValue(), lng.intValue());
   mapController.setCenter(point);

[android-developers] Porting RDP (Remote Desktop Protocol) to Android -- questions

[kirkbeaty]

Attempting to port RDP to Android ... saw someone had started this,
Desktoid/Connectoid, but that effort seems to have stopped .. and I
need this function immediately.   I have initial screen image of the
Desktop displayed (with some local Android GUI expert's help) on the
Android as a Bitmap.

There are several calls that RDP does which I can not find equivalents
in the Android GUI.   Those in the subject and others:

drawGlyph, setClip, Cursor,  IndexColorModel, etc.

Just to get the initial image was not without considerable effort ...
little things like which Bitmap.Config was used was key ... seems it
requires Bitmap.Config.RGB_565  (others did not work, and without
understanding as to why ?).

Willing to partner with any experts out there to get this completed.
Think it a very useful utility.

Of course, we need to have real ENTERPRISE WPA (even iPhone has this
out of the box) to really make this complete (instead of doing it on
emulator only :-)

Thanks for any assistance anyone can provide.

[android-developers] How to hang an outgoing call? (Revisited, Partly solved here)

[N0m0r3l13s]

Hi all,

I'm just doing an application that controls who to call and how many
rings let the call do. For example, to not wake up someone in the
morning we only do 3 tones...

I'm using the standard BroadcastReceiver method to stop the call from
going out.

I explain here for the people who want to do it, also.

[ Manifiest ]
1.- You need enough permissions:
uses-permission
android:name=android.permission.PROCESS_OUTGOING_CALLS /
uses-permission android:name=android.permission.CALL_PHONE /

To make calls and process outgoing calls.

2.- You need a broadcast receiver that catches the broadcast intent:

receiver android:name=.receiver.PhoneOutgoingCallReceiver
android:enabled=true 
intent-filter android:priority=0
action 
android:name=android.intent.action.NEW_OUTGOING_CALL /
/intent-filter
/receiver

[ Code ]

3.- You controls who can call in the:

@Override
public void onReceive(Context context, Intent intent) {

}

4.- If you don't want to let any call go out you can:

@Override
public void onReceive(Context context, Intent intent) {
setResultData(null);
}

5.- Use the to get the call information.

Bundle extras = intent.getExtras();

for(IteratorString 
it=extras.keySet().iterator(); it.hasNext();)
{
String key = it.next();
Log.d(LOG_TAG, key);
Log.d(LOG_TAG, Value:  + 
extras.getString(key));
}

BUT!

With this I can only censure calls, can't control how many time the
ring sounds.

the question is:


How can I delay a little bit the call cancellation?

I want to make it sound, for example, 3 seconds and then hang up.

Thank you all!

[android-developers] Transparency/Translucency working on emulator but not device

[Carl Minden]

I have tried to replicate the Transparency/Translucency effects
created in the API Demo(which works flawlessly) and the code i wrote
works on the emulator but not on my actual device(Google ION)

I copied the styles and colors.xml files from the API demos code and
set the theme of my activity I want to be transparent to @style/
Theme.Transparent in my activity i set my content view to a layout
which contains only a TextView containing :
TextView xmlns:android=http://schemas.android.com/apk/res/android;
android:id=@+id/text
android:layout_width=fill_parent
android:layout_height=fill_parent
android:gravity=center_vertical|center_horizontal
android:text=should have transparent background
/
 i have also tried setting the theme using: setTheme
(R.style.Theme_Transparent);

but nothing I try seems to work on the device, Any thoughts? is there
something I am missing?

Thanks

[android-developers] MemoryFile between processes

Hi,

I've been able to send data via shared memory between threads within a

passed.  The name for each call the MemoryFile's constructor was the
same.  Is it possible to share data between processes using a
MemoryFile?

speak in German and English, you live in a French speaking city and
you are part of the huge comunity from Latin América (nearly 25% of
Geneva's Market place speaks espanish)...you might write e-mails to
your family and olde friends once in a while..but with Android you
can't because that text language is not an option!!..

Using Android i'm surprise to find  that i can ONLY switch between
German, Italian, French, English and Portugues...

When deciding in between the Apple aplication for the Iphone and
Android i'm glad to see that apple let you switch between any single
text language..from Chinese to greek, japanese or Espanish etc..
without restriction..

What if you are part of those 10 thousend Chinese working at ONU
here?, or if your mother language is Sweedish?

[android-developers] IPsec support ?

[Ram]

Hi,

Is there IPsec support on Android.
Does Android support Application developers to make use of the IPsec ?

Thank you,

[android-developers] Re: Progress Dialog When Application Starts

[Brian Cloutier]

It's been a while since I last made an Android Application, so take this
with a grain of salt, but can't you just fire an intent to start the dialog
from onStart()?

On Mon, Jun 22, 2009 at 9:06 PM, Georgy georgearna...@gmail.com wrote:


 Hello,


 I am trying to initiate a progress bar when my application starts. The
 way my application works is that it collects info from the db that
 takes around 5 to 6 secs where the screen is completely black.  I am
 trying to initiate a progress dialog that gets triggered WITHOUT a
 button click or any other UI interaction but just when the user starts
 the application.

 All the previous posts handled something with handlers and UI
 interactions.

 any luck?

[android-developers] Re: Resizing an image

[p1erstef]

I met the same issue.
Here the workaround I found :

BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 8;
Bitmap bitmap = BitmapFactory.decodeFile(filename, options);
BitmapDrawable drawable = new BitmapDrawable(bitmap);
imageView.setImageDrawable(drawable);

Hope this helps,

Pierre

[android-developers] Re: Calibration with the environment may improve the readings ?!

[Gryyphyn]

I haven't looked through the source for the compass but there has to
be a set() method that you can apply a positive or negative value to,
possibly on tha app level. The compass is accurate enough so all you
would really have to do is assign a set() method to a menu calibration
option to allow the user to align with a standard compass and set the
value that modifies the OSD compass alignment, similar to the bubble
app and its calibration with the accelerometers. Just a thought...

Gryyphyn, out.

  I auto answer myself and the poor soul who fall on this post, so far
  the only way to calibrate is by making big 8-like gesture with the
  phone. Try it it worked for me.

 Yes, the digital compass in the G1 is self calibrating, but you have to make
 figure 8's or similar to make it do it, this isn't something you can do in
 software, the Android OS has magnetic field projections for the earth and if
 the current reading falls outside a specific range either something is
 artificially influencing it, such as the magnetic field in metals or
 electromagnetic fields caused by electronics and cars etc, or it needs
 calibration.

[android-developers] weird drawing on canvas bitmap

[sleith]

hi, i'm trying to draw bitmap in canvas.
the bitmap is used to draw text and background using canvas (named
canvasBitmap)
but the text or background that are drown to bitmap is not displayed,
as if it's out of bounds.
i have to translate the canvasBitmap at some points to make it draw at
right position.
The problem is i don't know how many pixel i should translate to.

here's the code example:

public OnDraw(Canvas c){

  Paint mBackgroundPaint = new Paint();
  mBackgroundPaint.setColor(Color.RED);

  String mText = Testing;

  Paint mFontPaint = new Paint();
  mFontPaint.setColor(Color.WHITE);

  //setting rect
  Rect mBackgroundRect = new Rect();
  mFontPaint.getTextBounds(mText, 0, mText.length(), mBackgroundRect);

  //the bitmap to be drawn a text and backgroundRect
  Bitmap mBitmap = Bitmap.createBitmap(mBackgroundRect.width(),
mBackgroundRect.height(), 
Bitmap.Config.ARGB_);
  Canvas mCanvasBitmap = new Canvas(mBitmap);

  //draw text and background to bitmap
  mCanvasBitmap.drawColor(Color.CYAN);
  mCanvasBitmap.drawRect(mBackgroundRect, mBackgroundPaint);
  mCanvasBitmap.drawText(mText, 0, 0, mFontPaint);

  //draw bitmap to canvas
  c.drawBitmap(mBitmap, 0, 0, null);
}

this will only drawn Cyan color, the text and red background is not
displayed
i have to translate for example :
mCanvasBitmap.translate(0, mBackgroundRect.height())

to make it displayed (but not 100% correctly position)
please help .
thx

[android-developers] Problem with createBitmap method

[hamlatzis]

My application crashes after I try to use the static Bitmap
createBitmap method to get a mutable bitmap in order to fill it later
with data.

If I only create one 1024x1024 the application works just fine, but
when I try to load the same image more than once (first making my
object null in each round) my application crashes on my third or
fourth try.

eg
Bitmap mpBitmap = null;

void CreateBitmap(int nWidth, int nHeight)
{
 if ( mpBitmap != null )
  mpBitmap = null;
 mpBitmap = Bitmap.createBitmap(nWidth, nHeight,
Bitmap.Config.ARGB_);
}


I get the same result if I create a smaller image but then I need more
runs before the crash. In all cases my application works just fine if
I only create the image (even 1024x1024) once, then exit my
application and run it again.

If there is a need for crash dump I can provide one.

Any help will be appreciated.

Thanks,

Iosif

[android-developers] SensorListener and MediaPlayer (Audio)

[Donn Felker]

I'm developing an application that responds to certain accelerometer
events such as movements to the left or right when a certain delta is
reached. When these deltas are fired I want to play a sound with the
MediaPlayer.

I'm using the Sensor Simulator by Open Intents to simulate sensor
events. I have the code set up, and I also have some basic
android.util.Log.e(...) statements telling me when these events are
fired. When I simulate the sensor, my deltas are met and my log
statements are output to LogCat. Therefore I know this is working.

However, I now want to play an audio resource file (mp3).

I added a method inside of the SensorListener definition called
PlayMedia(). This simply does the following:


private void PlayMedia()
{
if(mp != null)
{
android.util.Log.e(test,mp is not null, 
cleaning up!);
if(mp.isPlaying())
{
android.util.Log.e(test,Stopping the 
mp!);
mp.stop();
}
}
// is not playing.
android.util.Log.e(test,creating a new mp);
mp = MediaPlayer.create(getApplicationContext
(),com.MyCompany.Apps.MyApp.R.raw.mySound);

android.util.Log.e(test,Start the sound);
mp.start();
mp.reset();
}

However, when I calll this, no sound ever happens. The log messages
are output into LogCat. Therefore the code is making it into the
method, yet no sound is being output.

The odd thing is, I opened the ApiDemos and rand the Media demos and
they worked perfectly. The resource apidemo worked and played the
sound in the emulator. However, in my testing, I cannot get it to
play.

I've done the following: Moved the player code outside of the
sensorlistener into the activity and then called the PlayMedia() from
within the nested SensorListner, and it still doesnt work.

The only thing different in this code than in the ApiDemo is that my
MediaPlayer is inside of the SensorListener (as shown below). I also
use getApplicationContext() because in the ApiDemo's the example shows
this as it is inside of an Activity.

Why would the sound _not_ play? Its a 56kbps file. I've also taken the
same resource from the APiDemo's and tried to use that and still, no
dice.

I'm also noticing that I'm having to fully qualify my resources (R)
which is kind of odd. Anyone know why that would happen? Would that be
the cause? I've deleted, the gen folder and regnerated it a few times
and I still have to fully qualify my Resources. (I'm using Eclipse).

Does anyone know why this would not work?


Thanks,

Donn

--- Code below --

private final SensorListener mListener = new SensorListener() {

private MediaPlayer mp;

private final float[] mScale = new float[] { 2, 2.5f, 0.5f }; //
accel

private float[] mPrev = new float[3];

public void onSensorChanged(int sensor, float[] values) {
boolean show = false;
float[] diff = new float[3];

for (int i = 0; i  3; i++) {
diff[i] = Math
.round(mScale[i] * (values[i] - 
mPrev[i]) * 0.45f);
if (Math.abs(diff[i])  0) {
show = true;
}
mPrev[i] = values[i];
}

if (show) {
// only shows if we think the delta is big enough, in 
an attempt
// to detect serious moves left/right or up/down

 (
+ values[0] + ,  + values[1] + ,  + 
values[2] + )
+  diff( + diff[0] +   + diff[1] + 
  + diff[2]
+ ));

if ((gestX || gestY)  !(gestX  gestY)) {


if (gestX) {
if (x  0) {
PlayMedia();
android.util.Log.e(test,
 LEFT

[android-developers] handling events (click, tap, touch) for map (mapview, mapactivity)

[maijau]

Hello,

could anyone point me to some documentation or code on what's the
official way to handle events on a mapview or within a mapactivity? I
have searched around, there seem to be lots of questions regarding
this issue, few answers, and every answer is different.
As an example, I want to do something similar to the MyTracks
application: on a touch on the map, the builtin zoomcontrols appear,
panning still works, and in addition, other controls (the next/prev)
buttons are shown.

It seems I cannot achieve the desired effect using standard event
handlers, e.g. I could not get it to work by setting an
onClickListener or onTouchListener and implementing onClick()/onTouch
().

What is not clear to me:
- do I have to go directly to using overlays to achieve such an
effect? I understood overlays are more intended to display data on
maps, as opposed to controls?
- do I have to subclass mapview or mapactivity or both?
- is there a way without extending mapview, mapactivity and just
employing the standard event handling interface?

Thanks
Martin

[android-developers] Integrate your own application into the Maps application

[patschius]

Hello,

My question is: Is it possible to alter the standard Maps application
on Android in such a way that it is able to show for example some
specific POIs on the map

Google Latidude enhances Google Maps for its purposes in this way.

So is it possible for a developer outside of Google to enhance the Map
application too?

I have searched for the source of the Map application but did not
found anything. Is this part not Open Source?

thx for your answers

[android-developers] Skype Lite Intent Mangement

[Rick]

Does anyone know if it is possible to open up skype lite chat using
intents or some other API?

Suppose I wanted to create a short cut for a contact and I had their
skypename or skype id or skype email.

Would it be possible to do something like:
Intent i = new Intent(
 Intent.ACTION_VIEW,
 Uri.parse(skype:ladiesman217?chat)
);
i.setComponent(
new ComponentName(
 com.skype.android.lite,
 com.skype.android.lite.SkypeActivity)
);
startActivity(i);

I've pinged the Skype developer community about this with no results,
has anyone had any lucky with this?
